This is a perennial question that appears in various forms, I know, but it usually is asked in a moral or economic context; e.g. “Is someone immoral for not being as smart as Ayn Rand?” (obviously no, because morality and intelligence are unrelated) or, “Is someone destined to starve because his highest form of economic productivity is carrying around heavy objects?” (no, because of the law of comparative advantage).
My question is how to answer the allegation that Objectivism is an elitist philosophy, like Aristotelianism (of course, it is true that Aristotelianism is elitist), because only a fairly intelligent person would be able to grasp the abstract concepts necessary to really understand the philosophy. Of course, anyone could memorize the tenets of Objectivism unthinkingly and dogmatically, as so many do with Christianity in church on Sundays, but he would then be applying as a system of rules and commandments, not as a system of principles. In order to apply it as a set of principles, though, he would have to know the essentials of the entire philosophy, from metaphysics through politics, would have to grasp the most abstract of abstractions, such as the law of identity, and their full implications. Judging from my own personal experience, many people are simply incapable of such thought, whether from birth or through their upbringing is irrelevant: they just can’t do it.
Now, such people, I believe, could do fairly well in a society dominated by Objectivism simply by treating it as a system of rules and copying what other successful people do, but such second-handedness would, ipso facto, be in contravention of the most basic principles of Objectivism, of cognitive independence in particular. This problem is already well-known: the entire “Randroid” stereotype of Objectivists comes from this sort of person who superficially adopts the philosophy without actually understanding it. As and if Objectivism achieves greater popularity, it will only become worse. For example, to return to Christianity, there are a small minority of people who really understand that religion and a huge hoard which goes around repeating slogans and dogmas; the same applies for Marxism, environmentalism, conservatism, and all other religions and intellectual camps.
How should this charge of elitism be answered? What should men with such second-rate minds do to live by Objectivism while preserving their cognitive independence? Does the inability to fully grasp abstract ideas prevent one from living by reason?
