Ayn Rand preached that contradictions do not exist, but she based her philosophy on the notion of the prefect man being the fountainhead of all progress. A perfect man is a contradiction in terms—as Eliezer Berkovits notes in his essay, “God in History”: “Why ask for continuous miracles to rectify what goes wrong in the world? Would it not be simpler to ask for the creation of a perfect man, who would be so endowed by nature as to be incapable of committing any evil? The answer, of course, is even simpler than the question is naive. A perfect man is, in this sense, a contradiction in terms; it is an impossibility. A man incapable of doing wrong would not be human. The imperfection of human nature is inseparable from its most significant asset: Its potential for goodness, its capacity for responsible decision and action.” Berkovits is making a good point. Unless a man has the capacity to be wrong, he cannot have the potential to be right; a man who is so prefect that he never makes any mistakes, cannot do anything right, which means that he won’t be perfect—thus the concept of perfect man is a contradiction.
