[The necessary-contingent dichotomy] was interpreted in the twentieth century as follows: since facts are learned by experience, and experience does not reveal necessity, the concept "necessary facts" must be abandoned. Facts, it is now held, are one and all contingent --- and the propositions describing them are "contingent truths." As for necessary truths, they are merely the products of man's linguistic or conceptual conventions. They do not refer to facts, they are empty, "analytic," "tautological." [107]
Although not all or even most contemporary philosopher accept the necessary-contingent dichotomy, those that do advocate it believe in something close to what Peikoff describes. In other words, Peikoff has not grossly misstated this particular view, which is unusual for him. What, then, is his objection to this dichotomy? His main objection is the view, supposedly entailed by the dichotomy, that facts are contingent. Such a view, contends Peikoff,
represents a failure to grasp the Law of Identity. Since things are what they are, since everything that exists possesses a specific identity, nothing in reality can occur by chance. The nature of an entity determines what it can do and, in any given set of circumstances, dictates what it will do. The Law of Causality is entailed by the Law of Identity. Entities follow certain laws of action in consequence of their identity, and have no alternative to doing so. [108-109]
