Critics have often ignored Rand's epistemology as well. The fact is, it's Rand's ethics and politics that stirs up the animals on both sides, pro and con. Those critics that have tried to analyze the Objectivist epistemology have either gotten lost in the thickets or have become consumed by purely technical issues that most people don't care about. For me, Rand's epistemology could be reduced to two salient points: a denial (or at least mis-characterization) of the unconscious, intuitive phases of human thought; and the insistence that every word has an "objectively correct" definition. Those are the most important, or at least the most relevant, points of Rand's epistemology. By importance I mean: they are the most fundamental to what Rand was trying to accomplish in her overall philosophy. Admittedly, this is not obvious at first glance, so some explanation is in order.

How I Became a Critic of Objectivism 4
Rand's epistemology constitutes the most intimidating part of the Objectivist philosophy. Introduction to Objectivist Epistemology is a difficult book, even for Objectivists. By the time Ayn Rand wrote it, she had already secured herself in an echo chamber from which no criticism could ever reach her. IOTE was accepted by her disciples as a gospel that could not be questioned. But how much of the theory does the typical Objectivist actually understood or care about? Other than a few Rand nerds, I don't think most Objectivists give a fig for IOTE. They may be pleased it exists, allegedly serving as a base for Rand's ethics and the politics. But they could care less about the largely technical issues raised in IOTE.

Ayn Rand & Epistemology 43
Analytic-Synthetic Dichotomy 16: Falsifibility. Toward the end of his essay on the Anayltic-Synthetic Dichotomy, Peikoff tackles falsifiability:
Those who claim to distinguish a posteriori and a priori propositions commonly maintain that certain truths (the synthetic, factual ones) are "empirically falsifiable," whereas others (the analytic, logical ones) are not. In the former case, it is said, once can specify experiences which, if they occurred, would invalidate the proposition; in the latter, one cannot. For instance, the proposition "Cats give birth only to kittens" is empirically falsifiable" because one can invent experiences that would refute it such as the spectacle of tiny elephants emerging from a cat's womb. But the proposition "Cats are animals" is not "empirically falsifiable" because "cat" is defined as a species of animal....
Observe the inversion propounded by this argument: a proposition can qualify as a factual, empirical truth only if man is able to evade the facts of experience and arbitrarily ... invent a set of impossible circumstances that contradict these facts; but a truth whose opposite is beyond man's power of invention, is regarded as independent of and irrelevant to the nature of reality, i.e., as an arbitrary product of human "convention." [IOTE, 117-118]

Ayn Rand & Epistemology 24
Definitions 9: Doctrine of Verbalism. Rand is very clear on the relation between knowledge and definitions:
There is a serious problem with the Objectivist view of definitions that neither Rand nor her followers have ever adequately answered. The truth and falsehood of man's knowledge cannot possibly rest on definitions, because definitions are ultimately circular. One word is merely defined by other words; so that to expect to find truth and rationality in definitions is to expect what can never be found. As Karl Popper explained in The Open Society and Its Enemies:
The truth or falsehood of all of man’s conclusions, inferences, thought and knowledge rests on the truth or falsehood of his definitions. [IOTE, 49]
Definitions are the guardians of rationality, the first line of defense against the chaos of mental disintegration. [RM, 77]

Ayn Rand & Epistemology 23
Definitions 8: Doctrine of the Hierarchy of Knowledge. Rand had the habit of drawing dubious premises from trivial premises. With her doctrine of the hierarchy of knowledge, we find her at her old tricks:
That some concepts are "wider" than others — that animal, for example, is wider than mammal, and mammal wider than deer — is something so trivial that hardly anyone has bothered making a fuss about it before Rand. But the way some Objectivists talk about the hierarchy of knowledge, you would think that only Rand noticed it, while everyone else is in denial that concepts have any such structure. "Knowledge is hierarchal," Rand's disciples keep insisting; to which the obvious retort is, "So what!" The problem with Rand's hierarchy of knowledge is not that it is wrong but that Objectivists exaggerate its importance.
[There is a] long conceptual chain that starts from simple, ostensive definitions and rises to higher and still higher concepts, forming a hierarchical structure of knowledge so complex that no electronic computer could approach it. It is by means of such chains that man has to acquire and retain his knowledge of reality. [RM, 18]
To know the exact meaning of the concepts one is using, one must know their correct definitions, one must be able to retrace the specific (logical, not chronological) steps by which they were formed, and one must be able to demonstrate their connection to their base in perceptual reality. [IOTE, 50]

Ayn Rand & Epistemology 21
Definitions 6: Doctrine of Essentialism. Karl Popper provides the following gloss on essentialism:
Like Plato, Aristotle believed that we obtain all knowledge ultimately by an intuitive grasp of the essences of things. 'We can know a thing only by knowing its essence', Aristotle writes, and 'to know a thing is to know its essence'. A 'basic premiss' is, according to him, nothing but a statement describing the essence of a thing. But such a statement is just what he calls a definition. Thus all 'basic premisses of proofs' are definitions.
...Aristotle considers the term to be defined as a name of the essence of a thing, and the defining formula as the description of that essence. And he insists that the defining formula must give an exhaustive description of the essence or the essential properties of the thing in question; thus a statement like 'A puppy has four legs', although true, is not a satisfactory definition, since it does not exhaust what may be called the essence of puppiness, but holds true of a horse also; and similarly the statement 'A puppy is brown', although it may be true of some, is not true of all puppies; and it describes what is not an essential but merely an accidental property of the defined term.
But the most difficult question is how we can get hold of definitions or basic premisses, and make sure that they are correct - that we have not erred, not grasped the wrong essence. Although Aristotle is not very clear on this point, there can be little doubt that, in the main, he again follows Plato.... Aristotle's view is less radical and less inspired than Plato's, but in the end it amounts to the same. For although he teaches that we arrive at the definition only after we have made many observations, he admits that sense experience does not in itself grasp the universal essence, and that it cannot, therefore, fully determine a definition. Eventually he simply postulates that we possess an intellectual intuition, a mental or intellectual faculty which enables us unerringly to grasp the essences of things, and to know them. And he further assumes that if we know an essence intuitively, we must be capable of describing it and therefore of defining it. (His arguments in the Posterior Analytics in favour of this theory are surprisingly weak. They consist merely in pointing out that our knowledge of the basic premisses cannot be demonstrative, since this would lead to an infinite regress, and that the basic premisses must be at least as true and as certain as the conclusions based upon them. 'It follows from this', he writes, 'that there cannot be demonstrative knowledge of the primary premisses; and since nothing but intellectual intuition can be more true than demonstrative knowledge, it follows that it must be intellectual intuition that grasps the basic premisses.' In the De Anima, and in the theological part of the Metaphysics, we find more of an argument; for here we have a theory of intellectual intuition - that it comes into contact with its object, the essence, and that it even becomes one with its object. 'Actual knowledge is identical with its object.')
Summing up this brief analysis, we can give, I believe, a fair description of the Aristotelian ideal of perfect and complete knowledge if we say that he saw the ultimate aim of all inquiry in the compilation of an encyclopaedia containing the intuitive definitions of all essences, that is to say, their names together with their defining formulae; and that he considered the progress of knowledge as consisting in the gradual accumulation of such an encyclopaedia, in expanding it as well as in filling up the gaps in it and, of course, in the syllogistic derivation from it of 'the whole body of facts' which constitute demonstrative knowledge.

Rand and Empirical Responsibility 11
“Definitions preserve ... the logical order of their hierarchical interdependence.” This touches on the Objectivist contention that knowledge is hierarchical. The concept animal is a step higher in the conceptual hierarchy than mammal, for example. Is it true, as Rand asserts, that definitions "preserve" the "logical order" of this hierarchy?
Rand derived her doctrine of definitions from Aristotle. It is not however clear what she means by "logical order," or how definitions go about preserving it. What Rand seems to have in mind (although she's none too clear about it) is the ideal of knowledge as a complete "logical" structure (logical in this sense meaning: integrated without contradiction). In this, Rand is mirroring Aristotle's ideal of knowledge as (in the words of Karl Popper) "an encyclopaedia containing the intuitive definitions of all essences, that is to say, their names together with their defining formulae."
For better or worse, there exists no compelling evidence that knowledge works this way; nor does Rand (or her disciples) provide any evidence, or seem in the least interested in the empirical side of this issue. Yet there is a great deal of evidence that formal definitions are of little importance to understanding the meaning of words. Most words are learned unconsciously, without the aid of formal definitions or dictionaries. Moreover, it can easily be observed that many people understand the meaning of words without being able to provide formal definitions for them. Just ask anyone (besides a linguist or a grammarian) to define the word the and you'll see what I mean.
Now it could be argued that Rand's theory of definitions is not confined to mere formal definitions, but applies to "tacit" or "implicit" definitions as well (whatever those might be), and that when she declares that definitions preserve the logical order of conceptual hierarchies, she is not distinguishing whether those definitions are consciously formalized or are merely implicit and tacit. Yet if this is so, Rand needs to explain (1) how she knows this to be true; and (2) provide compelling evidence for her view.
“Words without definitions are not language but inarticulate sounds.” If by definitions, Rand means consciously formalized definitions (after Aristotle methods of essentialist definitions), this is a grossly implausible position, for the reasons provided above. If Rand means merely "tacit" or "implicit" definitions, in the absence of any evidence (none of which is provided by Rand), it is not clear that this is true (or if it is true, whether it has any significance). What would make a lot more sense would be Words without meanings are not language but inarticulate sounds. This suggests that Rand has confused the concept meanings with that of definitions. Definitions are explanations of what a word means; but this does not mean that a definition is identical with the meaning. The meaning of a term can be understood without defining it, because knowledge is largely tacit and intuitive, rather than formalized and logical, as Rand seems to assume.
“The process of forming, integrating and using concepts is not an automatic, but a volitional process.” Given how important this assertion is to some of Rand's claims about history and morality, Rand's unwillingness to provide any evidence for it is most unfortunate. I suspect it never occured to her that she needed to provide evidence, because empirical responsibility was not part of her basic MO. In any case, had she tried to find evidence for it, she almost certaintly would have realized that the statement is not true. Many concepts, perhaps even most concepts, are formed unconsciusly, without anything remotely describable as volition having anything at all to do with the process. Indeed, this is an obvious fact that can be gleaned merely by observing young children learning to speak. How Rand could have ignored and/or evaded these obvious facts is difficult to comprehend.
An animal cannot perform a process of abstraction. Really? How on earth did Rand know this? For it's not clear at all that this is true. Consider the testimony of two neuroscientists, Jorge Martins de Oliveira and Julio Rocha do Amaral:

Although there is no general agreement, we believe that other species are also capable to develop abstractions. Some primates and cetaceans, without any doubt, have abstract conceptions, but these must be very tenuous and, certainly, they never develop, as humans do, to a point of giving rise to high creativity. And, even if it so happened, it would be an innocuous creativity, since they lack the physical attributes to allow them to build up something that could be considered significant and concrete. In spite of these handicaps, the exercise of conscious and abstract thoughts, among dolphins and superior simians, has been widely evidenced.

Objectivism & “Metaphysics,” Part 16
Seddon’s defense of Rand’s free will. In Fred Seddon’s review of my book Ayn Rand Contra Human Nature, we find the following curious assertion: “I would point out that the Objectivist position is very close to that of Karl Popper.” While superficially there are points in common between Popper’s criticism of determinism and Rand’s, the differences are more telling.
1. First and perhaps most important of all, Popper doesn’t support free will and oppose determinism in order to support a view of human nature that goes against the wisdom of human experience and the evidence of experimental and evolutionary psychology. If Rand’s view of free will were correct, predictions based on human nature would be untenable, since such predictions are generally based on the idea that there exist innate tendencies which will favor certain results over others. Hence, if I claim that great wealth tends over time to soften a nation, making it ripe for destruction, I’m making an inference from human nature. This is an inference which Rand would have rejected on the grounds that people have free will and can choose not to be “softened” by wealth. By claiming that innate tendencies don’t exist, Rand undermines the ability to understand human motivation and the evolution of the social order.

This is an inference which Rand would have rejected on the grounds that people have free will and can choose not to be “softened” by wealth. By claiming that innate tendencies don’t exist, Rand undermines the ability to understand human motivation and the evolution of the social order.
Leonard Peikoff, in his short memoir “My Thirty Years with Ayn Rand,” unintentionally demonstrates how Rand’s views on these issues caused havoc in her personal life. “Ayn Rand refused to make collective judgments [about the individuals in her circle]. Each time she unmasked one of these individuals [i.e., broke from them] she struggled to learn from her mistake. But then she would be deceived again by some new variant.” [VOR, 350] Rand’s failure to make “collective judgments” is another way of saying that she failed to respect the home truths of human nature. She expected her acolytes to think, feel and behave like the heroes of Atlas Shrugged, rather than as human beings. She failed to recognize that many of the weaknesses which plague the human animal are congenital, rooted in biology and the human condition, and that they can never be overcome (assuming they can be overcome at all) if they are not first recognized and dealt with in the open.
Although Popper was every bit as much an opponent of determinism as was Rand, this did not lead him to adopt a view of free will that, at least by implication, denies that human behavior is explicable. Popper does not claim, as Peikoff once did, that what makes a person “think or evade” “cannot be further explained.” No, on the contrary, Popper admits that human behavior is at least somewhat predictable:
2. Popper’s arguments against determinism are far more complex and sophisticated than Rand’s. In fact, they are too complicated to be reproduced here. Moreover, Popper does not claim that his arguments decisively refute metaphysical determinism or achieve the status of self-evident axioms. He recognizes that “metaphysical” determinism, because it is “metaphysical,” is irrefutable (i.e., untestable). Popper merely seeks to refute a specific type of determinism, namely, what he calls “scientific” determinism.
3. In his book on determinism, Popper mentions an argument issued by the geneticist J.B.S. Haldane. This argument, first introduced by Haldane in 1898, is so similar to Rand’s that one wonders if there isn’t a connection between the two. Popper quotes Haldane as follows: “I am not myself a materialist [Haldane wrote,] because if materialism is true, it seems to me that we cannot know that it is true. If my opinions are the result of the chemical processes going on in my brain, they are determined by the laws of chemistry, not those of logic.” Although Popper sympathizes with the intent of Haldene’s argument, he understands its weaknesses. “This somewhat strange argument does not, of course, refute the doctrine of “scientific” determinism,” Popper acknowledges.
In conclusion: Seddon's claim that Objectivism's position on free will and determinism is "very close" to that of Karl Popper is a palpable exaggeration.

It is undeniable that we often predict the behavior of animals, and also of men, very successfully. Moreover, these predictions tend to become better and better as we learn more and more about the man or the animal; and they may be still further improved by a systematic study of their behavior. There is no reason why this process of learning more and more about behavior should ever come to an end. [The Open Universe, 15]

Objectivism & “Metaphysics,” Part 11
Logic and reality. Chris Sciabarra sums up the Objectivist position on this issue better than any Objectivist:
What on earth does it mean to say that contradictions cannot exist in reality? What kind of processes or events is this supposed to rule out? What would a “contradiction in reality” look like? What does it mean, in empirical terms, to say that an atom cannot be a non-atom? Or is it merely that we simply cannot conceive such “contradictions in reality”? But if we cannot conceive what a “contradiction in reality” might be, what is the point of saying such a phenomena cannot exist? If we cannot even imagine its existence, it has no relevance, either as an error or a falsehood. So again, what is this mythical gremlin, the “contradiction in reality,” and why should we bother our heads with it?
Rand’s confusion here runs deep, and stems from confusing different aspects or realms of existence and trying to assume that logic, in order to be cognitively useful, must be valid in every domain or realm of existence. The philosophers George Santayana and Karl Popper, working entirely independent of one another, distinguished at least three realms or “worlds”:
While Santayana’s realms of matter and spirit are largely identical to Popper’s worlds 1 and 2, there are important difference between the Santayana’s realm of essence and Popper’s world 3. Santayana’s realm of essence includes all possible meanings, whether anyone has experienced them or not. Popper, on the other hand, tends to confine his world 3 to those ideas or meanings produced by the human mind. These differences are not important for the points I will be trying to make about logic and reality in this post.
Now where does logic actually hold true? Does it hold true in all three realms/worlds? Or in only one or two of them? Or in none of them? Well, let’ s take a look, first, at the realm of matter. Does it hold true for that? No, it doesn’t. This is demonstrated by an experiment proposed by Karl Popper. Popper begins by noting that when a logical statement such as 2+2=4 is applied to reality (as when someone puts 2+2 apples in basket),
So logic does not in all respects hold good for the physical world. What about the mental world? Here I draw on Santayana’s testimony:
Where, then, is logic fully applicable? According to Popper, “Logical necessity exists only in world 3. Logical connection, logical relations, logical necessities, logical incompatibility — all that exists only in world 3. So it exists in our theories about nature. In nature this does not exist, there is no such thing.” [Knowledge and the Body-Mind Problem, 41]
Santayana regards logic to be “merely a parabolic excursion in the realm of essence.” If a logical construction is true, this truth derives, not from logic, but from conformity to the order of nature.
In other words, when a logical proposition turns out to be true, the truth of that statement arises, not from its logic, but by the fact that it is exemplified by the real world. It is the real world, not logic, which makes a thing true. Facts, nature, reality constitute the standard of truth, not logic. I would also note that, while there exists an infinite number of logical expressions (after all, every mathematic equation is a logical expression, and there are an infinite number of such expressions), only a small fraction of those will find exemplification in existence. Logical validity is therefore no warrant of truth.
If existence were actually logical, as conceived by Objectivists, then reality would have to be a system of ideal relations, like we find imagined in the idealist reveries of Plato and Hegel. In other words, this view only makes sense on idealist assumptions. But on realist assumptions, reality may be anything it pleases. It is not for the mind to determine how reality must be. On the contrary, the mind must accept whatever it finds. And since we have not experienced every possible fact of nature, all theories about facts are ultimately conjectural, and must be revised or overthrown if a fact is discovered that contradicts them. Facts, therefore, for all practical intents, are contingent — which effectively means, alogical and "unnecessary." If a fact contradicts one of our theories about reality, it is the theory that has to go, not the fact.
I suspect there will be Rand apologists who will protest that Objectivism denies no facts. Well, that’s not so clear, as we shall see in my next post.
Like Aristotle, Rand believes that logic is inseparable from reality and knowledge. She states: “If logic has nothing to do with reality, it means the Law of Identity is inapplicable to reality.” But, as Peikoff explains: “The Law of Contradiction … is a necessary and ontological truth which can be learned empirically.” … [For Rand,] logic is certainly a law of thought, insofar as it is “the art of non-contradictory identification.” But logic is true in thought only because contradictions cannot exist in reality. Rand writes: “An atom is itself, and so is the universe; neither can contradict its own identity; nor can a part contradict the whole.” [Ayn Rand: The Russian Radical, 139-140]
What on earth does it mean to say that contradictions cannot exist in reality? What kind of processes or events is this supposed to rule out? What would a “contradiction in reality” look like? What does it mean, in empirical terms, to say that an atom cannot be a non-atom? Or is it merely that we simply cannot conceive such “contradictions in reality”? But if we cannot conceive what a “contradiction in reality” might be, what is the point of saying such a phenomena cannot exist? If we cannot even imagine its existence, it has no relevance, either as an error or a falsehood. So again, what is this mythical gremlin, the “contradiction in reality,” and why should we bother our heads with it?
Rand’s confusion here runs deep, and stems from confusing different aspects or realms of existence and trying to assume that logic, in order to be cognitively useful, must be valid in every domain or realm of existence. The philosophers George Santayana and Karl Popper, working entirely independent of one another, distinguished at least three realms or “worlds”:
- Realm of Matter/World 1: the physical world, the world of matter existing in time and space.
- Realm of Spirit/World 2: consciousness, the world of mental objects and events.
- Realm of Essence/World 3: the world of ideas, meanings, theories, problems, etc.
While Santayana’s realms of matter and spirit are largely identical to Popper’s worlds 1 and 2, there are important difference between the Santayana’s realm of essence and Popper’s world 3. Santayana’s realm of essence includes all possible meanings, whether anyone has experienced them or not. Popper, on the other hand, tends to confine his world 3 to those ideas or meanings produced by the human mind. These differences are not important for the points I will be trying to make about logic and reality in this post.
Now where does logic actually hold true? Does it hold true in all three realms/worlds? Or in only one or two of them? Or in none of them? Well, let’ s take a look, first, at the realm of matter. Does it hold true for that? No, it doesn’t. This is demonstrated by an experiment proposed by Karl Popper. Popper begins by noting that when a logical statement such as 2+2=4 is applied to reality (as when someone puts 2+2 apples in basket),
it becomes a physical theory, rather than a logical one; and as a consequence, we cannot be sure whether it remains universally true. As a matter of fact, it does not. It may hold for apples, but it hardly holds for rabbits. If you put 2+2 rabbits in a basket, you may soon find 7 or 8 in it. Nor is it applicable to such things as drops. If you put 2+2 drops in a dry flask, you will never get four out of it. If you answer that these examples are not fair because something has happened to the rabbits and the drops, and because the equation ‘2+2=4’ only applies to objects in which nothing happens, then my answer is that, if you interpret it in this way, then it does not hold for ‘reality’ (for in ‘reality’ something happens all the time), but only for an abstract world of distinct objects in which nothing happens. To the extent, it is clear, to which our real world resembles such an abstract world, for example, to the extent to which our apples do not rot, or rot only very slowly, or to which our rabbits or crocodiles do not happen to breed; to the extent, in other words, to which physical conditions resemble pure logical or arithmetical operation of addition, to the same extent does arithmetic remain applicable. But this statement is trivial.” [Conjectures and Refutations, 212]
So logic does not in all respects hold good for the physical world. What about the mental world? Here I draw on Santayana’s testimony:
Now as a matter of fact there is a psychological sphere to which logic and mathematics do not apply. There, the truth is dramatic. That 2+2=4 is not true of ideas. One idea added to another, in actual intuition [i.e., in conscious experience], makes still only one idea, or it makes three: for the combination, with the relations perceived, forms one complex essence, and yet the original essences remain distinct, as elements in this new whole. This holds true of all moral, aesthetic, and historical units: they are merged and reconstituted with every act of apperception. [Realm of Truth, 410]
Where, then, is logic fully applicable? According to Popper, “Logical necessity exists only in world 3. Logical connection, logical relations, logical necessities, logical incompatibility — all that exists only in world 3. So it exists in our theories about nature. In nature this does not exist, there is no such thing.” [Knowledge and the Body-Mind Problem, 41]
Santayana regards logic to be “merely a parabolic excursion in the realm of essence.” If a logical construction is true, this truth derives, not from logic, but from conformity to the order of nature.
The only serious value of … logical explorations would lie in their possible relevance to the accidents of existence. It is only in that relation and in that measure that mathematical science would cease to be mere play with ideas and would become true: that is, in a serious sense, would become knowledge. Now the seriousness of mathematics comes precisely of its remarkable and exact relevance to material facts, both familiar and remote. And this in surprising measure. For when once any essence falls within the sphere of truth, all its essential relations do so too: and the necessity of these relations will, on that hypothesis, form a necessary complement to a proposition that happens to be true. This same necessity, however, would have nothing to do with truth if the terms it connects were not exemplified in existence. In this way mathematical calculations far outrunning experiment often [but not always!] turn out to be true of the physical world, as if, per impossible, they could be true a priori. [ibid, 409]
In other words, when a logical proposition turns out to be true, the truth of that statement arises, not from its logic, but by the fact that it is exemplified by the real world. It is the real world, not logic, which makes a thing true. Facts, nature, reality constitute the standard of truth, not logic. I would also note that, while there exists an infinite number of logical expressions (after all, every mathematic equation is a logical expression, and there are an infinite number of such expressions), only a small fraction of those will find exemplification in existence. Logical validity is therefore no warrant of truth.
If existence were actually logical, as conceived by Objectivists, then reality would have to be a system of ideal relations, like we find imagined in the idealist reveries of Plato and Hegel. In other words, this view only makes sense on idealist assumptions. But on realist assumptions, reality may be anything it pleases. It is not for the mind to determine how reality must be. On the contrary, the mind must accept whatever it finds. And since we have not experienced every possible fact of nature, all theories about facts are ultimately conjectural, and must be revised or overthrown if a fact is discovered that contradicts them. Facts, therefore, for all practical intents, are contingent — which effectively means, alogical and "unnecessary." If a fact contradicts one of our theories about reality, it is the theory that has to go, not the fact.
I suspect there will be Rand apologists who will protest that Objectivism denies no facts. Well, that’s not so clear, as we shall see in my next post.

Objectivism & “Metaphysics,” Part 1
Preliminaries. What on earth is all this nonsense that goes under the name “metaphysics”? Rand defined metaphysics as “the study of existence as such or, in Aristotle’s words, of ‘being qua being.’” Well, that sure narrows it down! More insightful is George Santayana’s take on the subject:
I have tended to follow Santayana’s usage of the word, regarding metaphysics as, in the main, empirically irresponsible speculation. Even when used to defend postulates that are basically sound, metaphysics remains, in the words of F. H. Bradley, “the finding of bad reasons for what we believe upon instinct.”
There is, however, one other usage of the word that should be noted. Karl Popper applied the word metaphysics to any claims or conjectures that are not empirically testable. Popper’s usage, while entirely blameless, is not one I normally honor.
Now following Santayana’s usage, I inevitably open myself up to complaints, often introduced in an angry tone, that, I too, have a metaphysics; that indeed, “having a metaphysics” is inevitable, since everyone has a “basic view of the world,” that is to say, a “metaphysics.” However, following Santayana, I don’t choose to call my so-called “basic view” of the universe metaphysical. It is merely, as Santayana calls it, cosmology or natural philosophy. And I entirely reject any attempt to determine matters of fact by means of logical or moral or rhetorical constructions. Such devices, I hold, cannot lead to truth, but only encourage rationalization and empty speculation.
What, then, is my “basic view of the universe”? In the broad essentials, it is not so different from Rand’s. It involves the fundamental assumptions involved in living. I presuppose, for instance, the existence of time, including a past that is gone and a future that is to come; the existence of a physical universe made up of gross objects in space; and the existence of consciousness, which perceives existence through the veil of ideas. Unlike Rand, I don’t believe these basic presuppositions can be defended or validated via axioms or logical argumentation. All these fundamental presuppositions may conceivably be illusory—that is to say, the arguments against them cannot be decisively refuted. They are presuppositions which nature has bred in us (probably via evolution) and which have proved their worth, not by logic, but through centuries of practice. They neither require nor are amenable to logical justification.
Rand takes a very different approach. She is an extreme foundationalist who believes that man’s fundamental presuppositions requires explicit logical justification; that in the absence of this justification, people will lose their ability to think for themselves and will become incapable of supporting a free society. Is there any evidence to support this contention? None that is convincing. The belief that all human contentions and presuppositions require explicit philosophical justification constitutes a false demand. Few people understand, let alone care, about such arcana. Rand’s foundationalism only serves to encourage rationalization, verbalism, essentialism, and other modes of empty speculation, and is often symptomatic of a dogmatic turn of mind that has trouble accepting the provisional and conjectural nature of knowledge. Rather than being an ally of realism, foundationalism tends to undermine it, as it forces the philosopher to adopt premises that are at odds with realism.
But more on this anon.
Metaphysics, in the proper sense of the word, is dialectical physics, or an attempt to determine matters of fact by means of logical or moral or rhetorical constructions. It arises by a confusion of those Realms of Being which it is my special care to distinguish. It is neither physical speculation nor pure logic nor honest literature, but (as in the treatise of Aristotle first called by that name) a hybrid of the three, materialising ideal entities, turning harmonies into forces, and dissolving natural things into terms of discourse. Speculations about the natural world, such as those of the Ionian philosophers, are not metaphysics, but simply cosmology or natural philosophy. [Scepticism and Animal Faith, vii]

Objectivism & History, Part 12
Eschatology. Eschatology is a part of theology or philosophy dealing with the ultimate destiny of humanity or end of the world. While Objectivism does not have an explicit eshatology, it’s philosophy of history contains obvious eshatological implications. Consider the following from the pen of Leonard Peikoff:
So Objectivism will “ultimately” triumph! Here we find the primary raison d’être of Rand’s philosophy of history. “It took decades of collectivist philosophy to bring this country to its present state,” Rand wrote to a correspondent in March of 1962. “And it is only the right philosophy that can save us. Ideas take time to spread, but we will only have to wait decades—because reason and reality are on our side.”
This optimistic prognosis was made over four decades ago, and still Objectivism has made little if any progress towards its “ultimate” triumph. Indeed, if by Objectivism we mean the purest, orthodox brand of that philosophy, we would have to admit that it has regressed since 1962, thanks to two major schisms in the movement, one involving Rand and her leading disciple Nathaniel Branden, the other involving Rand’s intellectual heir Leonard Peikoff and the movements most promising and effective advocate, David Kelley.
Since Rand’s 1962 prognosis has turned out to be so palpably wrong, how much faith should we place in Peikoff’s suggestion of an “ultimate” triumph? Given the intellectual foundation that these Objectivist hopes are based on, no faith should be placed in them. The Objectivist hope for an “ultimate” triumph is on the same level as the Marxist’s hope of for the eventual triumph of the communist paradise or the Christian’s hope for the rapture. It is an extra-empirical hope, without basis in fact, science or even good sense. It completely ignores what actually motivates human beings, substituting instead an entirely baseless schema of motivations based on abstruse metaphysical and epistemological notions that hardly anyone understands or cares for. Worst of all, it is a species of conceit so gross and intense that it boggles the mind: for it suggests that Rand and her disciples, simply by wagging their tongues and jiggling their pens, can “turn the reign of evil and save the world.” Under this notion of history, ideas become a kind of talisman or power. “In the beginning was the Word,” begins the Platonist gospel of John. Rand’s philosophy of history is merely a kind of secularist riff on this mystical theme.
Should this mystical, Platonist detour surprise us? Not at all. For that is the tradition of philsophy that Rand harkens from: the Platonic-Aristotelean tradition of metaphysics and wishful thinking, rather than the tradition of the Greek Naturalists, modern science and the critical empiricism of Hume and Popper.
From another point of view, however, [the power of philosophy to change the world] is not ominous—it can even be regarded as encouraging. For it means that if a good philosopher arises who answers and philosophically destroys [a pernicious philosopher like Kant], that will turn the reign of the evil and save the world. And such a philosopher has arisen in our time—in my judgment, at least, and I am sure in most of yours. I am speaking, of course, of Ayn Rand.
On the basis of the theory of history I have put forth today, therefore, it is proper to have hope for the future. I do think that Objectivism will triumph ultimately and shape the world’s course, and that today’s culture will be remember in the end only for what it is—which I refrain from saying.
So Objectivism will “ultimately” triumph! Here we find the primary raison d’être of Rand’s philosophy of history. “It took decades of collectivist philosophy to bring this country to its present state,” Rand wrote to a correspondent in March of 1962. “And it is only the right philosophy that can save us. Ideas take time to spread, but we will only have to wait decades—because reason and reality are on our side.”

Objectivism & History, Part 8
Kant contra Rand There appear to be many orthodox Objectivists still in denial about Kant’s influence on history. Despite never having read Kant or the philosophers Kant influenced, they are nevertheless certain that Kant’s influence is precisely as Rand limned it. This prejudice can easily be refuted by quoting any non-controversial account of Kant. Take, as an example, what Karl Popper writes about Kant in the Open Society:
Popper’s summation of Kant’s Critique is in line with the mainstream view. Kant’s attack on “pure reason” was not meant as an attack on knowledge as such, but only on speculative knowledge, i.e., claims of knowledge about matters of fact that aren’t backed by evidence. As Thomas Henry Huxley put it:
Kant’s basic position can be summed up from the famous aphorism from the preface of the second edition of The Critique of Pure Reason: “Concepts without percepts are empty; percepts without concepts are blind.” Whatever errors and mistakes Kant may have committed in explicating and developing this seminal insight, the principle itself remains sound. Nor would even Rand necessarily have disagreed with it, even if she might have quibbled about the terms in which the principle is expressed.
An anonymous commentator in an earlier post insisted “that Kant's philosophy and Objectivism are diametrically opposed.” This is a bit of exaggeration. Even in the field of ethics, where the differences between Kant and Rand are the most striking, there are still similarities (e.g., they are both absolutists, and they both believe in “autonomy”). So would Rand have necessarily disagreed with Kant’s view that “when leaving the field of experience, our speculation can have no scientific status”?
Orthodox Objectivists (including Rand herself) have always been vague on this point. While Rand and her disciples will occasionally stress the importance of keeping one’s concepts in touch with reality and avoiding what they call “floating abstractions,” if we judge Objectivists by how they act rather than on what they say it becomes clear that they really are quite attached to the type of speculative reason that Kant (and Hume) criticizes. Rarely do Rand or Peikoff provide detailed, convincing evidence for their numerous controversial assertions. If they deign to advance any kind of argument at all, it is nearly always of a wantonly speculative and, ipso facto verbalistic nature. Rand’s entire theory of human nature is merely a speculative leap from her equally speculative defense of free will! One can hardly get more rationalistic and non-empirical than that!
To the extent that there is real difference between Rand and Kant on this issue “pure” reason, it is Kant, not Rand, that is on the side of science, truth and realism. The world is weary of philosophers who seek to determine matters of fact with logical, rhetorical, or moral constructions. The sort of “reason” that Objectivists actually practice (as opposed to vague, amorphous “reason” they theorize about and provide genuflect-like homage to) is merely a futile exercise in generating concepts without percepts. Kant and Hume were right to criticize such an approach. To the extent that this aspect of their philosophy has been influential, it has been influential for the better. Objectivism, on the other hand, would, if it exercised any influence at all on this issue, would constitute a step backwards for the human intellect.
Kant, in his Critique of Pure Reason, asserted under the influence of Hume that pure speculation or reason, whenever it ventures into a field in which it cannot possibly be checked by experience, is liable to get involved in contradictions or ‘antinomies’ and to produce what he unambiguously described as ‘mere fancies’; ‘nonsense’; ‘illusions’; ‘a sterile dogmatism’; and ‘a superficial pretension to the knowledge of everything’. He tried to show that to every metaphysical assertion or thesis, concerning for example the beginning of the world in time, or the existence of God, there can be contrasted a counter-assertion or antithesis; and both, he held, may proceed from the same assumptions, and can be proved with an equal degree of ‘evidence’. In other words, when leaving the field of experience, our speculation can have no scientific status, since to every argument there must be an equally valid counter-argument. Kant’s intention was to stop once and forever the ‘accursed fertility’ of the scribblers on metaphysics.
Popper’s summation of Kant’s Critique is in line with the mainstream view. Kant’s attack on “pure reason” was not meant as an attack on knowledge as such, but only on speculative knowledge, i.e., claims of knowledge about matters of fact that aren’t backed by evidence. As Thomas Henry Huxley put it:
The aim of the Kritik der reinen Verunft is essentially the same as that of the Treatise of Human Nature, by which, indeed, Kant was led to develop that “critical philosophy” with which his name and fame are indissolubly bound up: and, if the details of Kant’s criticism differ from those of Hume, they coincide with them in their main result, which is the limitation of all knowledge of reality to the world of phenomena revealed to us by experience.
Kant’s basic position can be summed up from the famous aphorism from the preface of the second edition of The Critique of Pure Reason: “Concepts without percepts are empty; percepts without concepts are blind.” Whatever errors and mistakes Kant may have committed in explicating and developing this seminal insight, the principle itself remains sound. Nor would even Rand necessarily have disagreed with it, even if she might have quibbled about the terms in which the principle is expressed.

Objectivism & Religion, Part 12
Agnosticism. Peikoff has this to say of agnosticism:
Peikoff here misrepresents agnosticism. He equates agnosticism with the creed of “I don’t know” and “Anything is possible." Is Peikoff right in his description of agnosticism? Perhaps we should turn to some actual agnostics to find out. And there is no better witness to call to the stand than the man who originally coined the term, Thomas Henry Huxley. Here is Huxley’s description of agnosticism:
Now many Objectivists will protest Huxley’s use of the word faith, but here it is important to understand that Huxley is not advocating a blind faith (he was scientist, after all) but a justified faith—justified by the fruits of experience. Huxley understands that you cannot prove your starting points; that you have to begin with faith and then see how it works out. If your faith is corroborated by experiential trials that you subject it to, you are justified in keeping fast to it. Otherwise, you try something else. Agnosticism, then, for Huxley is simply the critical method of thinking. It means always keeping an open mind to new evidence. As Huxley puts it: “The results of the working out of the agnostic principle will vary according to individual knowledge and capacity, and according to the general condition of science. That which is unproven today may be proven by the help of new discoveries to-morrow. The only negative fixed points will be those negations which flow from the demonstrable limitation of our faculties. And the only obligation accepted is to have the mind always open to conviction.”
“Do not block the path of inquiry!” insisted philosopher C. S. Peirce. This is the great danger for those who believe that knowledge, in order to be useful, must be "certain:" that they will close their minds to new evidence, because, after all, the debate is over, certainty has been achieved! The path to inquiry is blocked by the de facto dogmatism of all claims to certainty. All Huxley’s agnosticism is trying to insist upon is to keep the mind open, keep the path to inquiry clear.
Peikoff mischaracterizes agnosticism as insisting on the proof of negatives. But that’s not in the least true. Agnosticism is merely pointing out that lack of evidence does not constitute proof that something doesn’t exist. This is not the same thing as saying that the all things are possible. Nor is it claiming we can’t have any beliefs or suspicions about extra-empirical entities such as the God of the Bible. There is nothing contradictory in an agnostic saying he doesn’t believe in that sort of God. But he doesn’t regard this belief as “certain” and determined for all time. The agnostic remains a steadfast fallibilist. He remains open to any new evidence that might be brought forth on the question. And so, when the agnostic H. L. Mencken was asked what he would do if, following his earthly demise, he suddenly found himself confronted by the twelve apostles, he answered: “I would simply say, ‘Gentlemen, I was mistaken.’”
[There is] a widespread approach to ideas which Objectivism repudiates altogether: agnosticism. I mean this term in a sense which applies to the question of God, but to many other issues also, such as extra-sensory perception or the claim that the stars influence man’s destiny. In regard to all such claims, the agnostic is the type who says, “I can’t prove these claims are true, but you can’t prove they are false, so the only proper conclusion is: I don’t know; no one knows; no one can know one way or the other.”
The agnostic viewpoint poses as fair, impartial, and balanced. See how many fallacies you can find in it. Here are a few obvious ones: First, the agnostic allows the arbitrary into the realm of human cognition. He treats arbitrary claims as ideas proper to consider, discuss, evaluate—and then he regretfully says, “I don’t know,” instead of dismissing the arbitrary out of hand. Second, the onus-of-proof issue: the agnostic demands proof of a negative in a context where there is no evidence for the positive. “It’s up to you,” he says, “to prove that the fourth moon of Jupiter did not cause your sex life and that it was not a result of your previous incarnation as the Pharaoh of Egypt.” Third, the agnostic says, “Maybe these things will one day be proved.” In other words, he asserts possibilities or hypotheses with no jot of evidential basis.
Peikoff here misrepresents agnosticism. He equates agnosticism with the creed of “I don’t know” and “Anything is possible." Is Peikoff right in his description of agnosticism? Perhaps we should turn to some actual agnostics to find out. And there is no better witness to call to the stand than the man who originally coined the term, Thomas Henry Huxley. Here is Huxley’s description of agnosticism:
Agnosticism … is not a creed, but a method, the essence of which lies in the rigorous application of a single principle. That principle is of great antiquity; it is as old as Socrates; as old as the writer who said, "Try all things, hold fast by that which is good" it is the foundation of the Reformation, which simply illustrated the axiom that every man should be able to give a reason for the faith that is in him; it is the great principle of Descartes; it is the fundamental axiom of modern science. Positively the principle may be expressed: In matters of the intellect, follow your reason as far as it will take you, without regard to any other consideration. And negatively: In matters of the intellect do not pretend that conclusions are certain which are not demonstrated or demonstrable. That I take to be the agnostic faith, which if a man keep whole and undefiled, he shall not be ashamed to look the universe in the face, whatever the future may have in store for him.
Now many Objectivists will protest Huxley’s use of the word faith, but here it is important to understand that Huxley is not advocating a blind faith (he was scientist, after all) but a justified faith—justified by the fruits of experience. Huxley understands that you cannot prove your starting points; that you have to begin with faith and then see how it works out. If your faith is corroborated by experiential trials that you subject it to, you are justified in keeping fast to it. Otherwise, you try something else.

An Objectivist critique of Popper examined
Nicholas Dykes' critique of Popper, linked by the poster Ian, while not as bad as most such Rand-inspired criticisms, does have its share of serious problems.
Dykes begins his critique by complaining about Popper's tone of assurance.
Dykes unquestioningly accepts the Platonic view that equates knowledge with certainty, asserting that all denials of certainty are "self-contradictory," because "in the absence of certain knowledge one is either forced into a position involving some kind of unfounded conviction, belief or faith, or into scepticism." Says who? Dykes here make use of an oft-repeated Objectivist fallacy: the either-or fallacy, where we are given the choice between the Objectivist position and several unappetizing alternatives. But who says that the only alternative between certain knowledge is unjustified belief and skepticism? What about probable knowledge? What about degrees of reliability? If one knowledge claim can be regarded as superior to another, isn't that good enough for practical purposes?
Some of Dykes criticisms demonstrate a lack of familiarity with Popper's ideas. He accuses Popper, for instance, of refusing "to have anything to do with definitions." This is an exaggeration. Popper accepted scientific, or nominalistic, definitions; he simply has no use for essentialist definitions — another matter entirely. I can find no evidence that Dykes understands this distinction, or has any idea why essentialist definitions, and the scholastic mythology that has grown-up around them, deserve the criticism and scorn Popper directed at them.
Dykes essay particularly flounders when he attempts to explode Popper's critical rationalism by associating it with the views of Kant and Hume. He repeats the Objectivist canard that Hume's "whole argument" is in conflict with the Law of Identity. Alas, this misses the point entirely. Hume's argument is not directed at the Law of Identity, but at our knowledge of specific identities. How do we know which attributes of an object are constant and which are not? This is not a question which the Law of Identity can answer. Reminding ourselves that objects have identities is nothing to the purpose if we don't know, or can't be sure, what those identities are.
Dykes is equally clueless when it comes to Kant. Because Popper believed that all observations are "theory impregnated," Dykes assumes that Popper regards all theories as prior to experience, and even wonders whether Popper is "asking us to accept that the heliocentric theory came before observation of perturbations in planetary orbits?" Again, however, Dykes has missed the point. When Popper asserts that observations are "theory-impregnated" he is merely noting how hopeless it would be for an empty mind, bereft of any presuppositions or "theories," to make sense of observations. As Kant put it, "Thoughts without content are empty, intuitions [i.e., sense experiences] without concepts are blind." Regardless of whatever confusions and pendantries Kant may have stumbled into trying to elucidate this paradox in the Critique of Pure Reason, the principle itself constitutes one of the seminal insights of epistemology, easily corroborated by common experience and scientific investigation. I wonder if Dykes has any familiarity, let alone understanding, of it. Or does he believe that facts can be understood without any prior theories at all? Hardly a plausible position, if so. After all, how can a blank mind ever make neither heads nor tails of the bewildering complexity of sense experience, without at least some prior heuristic to guide it? It can't. So some measure of theory does appear to precede fact. How, then, on a realist framework, are we to account for this? Popper at least deserves credit for taking this issue seriously and trying to provide a non-idealist, non-Kantian solution to it. Since Dykes does not even appear to grasp that this is what Popper is attempting to do, his criticism is worthless. One cannot effectively criticize what one doesn't understand.
And that seems to be the over-riding problem of Dykes critique. His understanding of the problems Popper attempts to solve is minimal, at best. His attachment to Randian categories of interpretion has rendered him hopelessly naive in the face of problems originally posed by Hume and Kant and later elucidated by Pierce, Santayana, Popper and Polanyi. His outlook is still trapped in the scholasticism of Plato and Aristotle.
Dykes begins his critique by complaining about Popper's tone of assurance.
One thing which is quite certain is that Popper wrote with absolute assurance of his own rectitude, as I think the quotations in this paper reveal. For all his belittlement of knowledge and certainty, I have never read anyone who wrote so many books all imbued with such conscious certainty and authority— the authority of one who knows.Dykes appears to be annoyed by the fact that Popper never prefaces all his remarks with the phrase I suppose or I conjecture. Of course, it would be very tedious to proceed in this way. Dykes also takes Popper to task for declaring "I am not a belief philosopher. I do not believe in belief" while at the same time refusing, in other places in his work, to stop using the phrase I believe to state one of his positions. Here Dykes shows himself deaf to the ambiguity of language. Popper's phrase "I don't believe in belief" plays on two senses of the word belief to make a point. In the first sense of the term Popper is using it to describe certain belief, in the second, the sort of conjectural belief Popper supported. In other words, Popper is simply saying that he doesn't believe (in the conjectural sense of the term) in certainty.
Dykes unquestioningly accepts the Platonic view that equates knowledge with certainty, asserting that all denials of certainty are "self-contradictory," because "in the absence of certain knowledge one is either forced into a position involving some kind of unfounded conviction, belief or faith, or into scepticism." Says who? Dykes here make use of an oft-repeated Objectivist fallacy: the either-or fallacy, where we are given the choice between the Objectivist position and several unappetizing alternatives. But who says that the only alternative between certain knowledge is unjustified belief and skepticism? What about probable knowledge? What about degrees of reliability? If one knowledge claim can be regarded as superior to another, isn't that good enough for practical purposes?
Some of Dykes criticisms demonstrate a lack of familiarity with Popper's ideas. He accuses Popper, for instance, of refusing "to have anything to do with definitions." This is an exaggeration. Popper accepted scientific, or nominalistic, definitions; he simply has no use for essentialist definitions — another matter entirely. I can find no evidence that Dykes understands this distinction, or has any idea why essentialist definitions, and the scholastic mythology that has grown-up around them, deserve the criticism and scorn Popper directed at them.
Dykes essay particularly flounders when he attempts to explode Popper's critical rationalism by associating it with the views of Kant and Hume. He repeats the Objectivist canard that Hume's "whole argument" is in conflict with the Law of Identity. Alas, this misses the point entirely. Hume's argument is not directed at the Law of Identity, but at our knowledge of specific identities. How do we know which attributes of an object are constant and which are not? This is not a question which the Law of Identity can answer. Reminding ourselves that objects have identities is nothing to the purpose if we don't know, or can't be sure, what those identities are.
Dykes is equally clueless when it comes to Kant. Because Popper believed that all observations are "theory impregnated," Dykes assumes that Popper regards all theories as prior to experience, and even wonders whether Popper is "asking us to accept that the heliocentric theory came before observation of perturbations in planetary orbits?" Again, however, Dykes has missed the point. When Popper asserts that observations are "theory-impregnated" he is merely noting how hopeless it would be for an empty mind, bereft of any presuppositions or "theories," to make sense of observations. As Kant put it, "Thoughts without content are empty, intuitions [i.e., sense experiences] without concepts are blind." Regardless of whatever confusions and pendantries Kant may have stumbled into trying to elucidate this paradox in the Critique of Pure Reason, the principle itself constitutes one of the seminal insights of epistemology, easily corroborated by common experience and scientific investigation. I wonder if Dykes has any familiarity, let alone understanding, of it. Or does he believe that facts can be understood without any prior theories at all? Hardly a plausible position, if so. After all, how can a blank mind ever make neither heads nor tails of the bewildering complexity of sense experience, without at least some prior heuristic to guide it? It can't. So some measure of theory does appear to precede fact. How, then, on a realist framework, are we to account for this? Popper at least deserves credit for taking this issue seriously and trying to provide a non-idealist, non-Kantian solution to it. Since Dykes does not even appear to grasp that this is what Popper is attempting to do, his criticism is worthless. One cannot effectively criticize what one doesn't understand.
And that seems to be the over-riding problem of Dykes critique. His understanding of the problems Popper attempts to solve is minimal, at best.
