What was Ayn Rand Wrong About?

What follows is my answer to a question posed on Quora: What was Ayn Rand Wrong About?

On the technical side of things, Rand was wrong about (1) the need to validate man’s knowledge—i.e., foundationalism; (2) that concepts require definitions and that definitions can be true or false; (3) that emotions are automatic effects of man’s value premises; (4) that abstract philosophy determines the course of history; (5) and that emotions are not “tools of cognition.” If we wished to really get into the philosophical weeds, we could probably ferret out even more technical errors, but beyond a few hard-core Rand acolytes, I doubt that anyone really cares about any of these largely technical issues. Nowadays Rand is mostly known for her zealous affirmations of egoism, “selfishness,” and laissez-faire capitalism, and her concomitant denunciations of altruism and all forms of government interventionism. Perhaps her most influential contention is that freedom and capitalism require a moral foundation, by which she meant: convincing philosophical arguments on their behalf. This conviction is based, however, on faulty assumptions about moral philosophy, human reason and psychological motivation.

Peterson at OCON: A Quick and Dirty Review

Those of us who are cognizant of orthodox Objectivists at their worst knew that the discussion/debate with Jordan Peterson that was held at OCON could have ended very badly for the Randian cause. Luckily for the denizens of ARI, Brook and Salmieri managed to escape any serious mishaps. They wisely avoided challenging Peterson on issues relating to psychological science and tried to keep to discussion restricted to areas where they thought they had an advantage. Consequently Peterson delivered no Cathy Newman killshots (not that he wanted to) and Brook and Salmieri escaped relatively unscathed. While that's a kind of a win for Brook, on the other side of the coin, I don't believe things ended quite the way Brook had hoped. It appeared to me that Brook and Salmieri were using different strategies. One of the great weaknesses of orthodox Objectivism is that they have trouble understanding non-Objectivist thinkers. They are more interested in refuting and/or condemning people with different views than understanding them. This approach to their adversaries caused Brook to adopt a strategy that wound up backfiring. Brook seems to have gone into the debate under the illusion that Peterson is an opponent of metaphysical realism). At one point in the discussion, Brook waxed on about the independent existence of his water bottle, only to be stymied when Peterson kept agreeing with him.
