The assignment I gave myself for tonight is not to sell you on my philosophy, but on philosophy as such…What is my selfish interest in the matter? I am confident enough to think that if you accept the importance of philosophy and the task of examining it critically, it is my philosophy that you will come to accept. Formally, I call it Objectivism, but informally I call it a philosophy for living on earth.
Ayn Rand's egoism is untainted by any element of the mind/body dichotomy. On her view, man can achieve happiness by acting in his long-term, rational self-interest, neither sacrificing himself to others, nor sacrificing others to himself. In the long run, a man can erase conflicts within his soul, not by repression, but by an active process of rethinking the subconscious premises on which certain emotions are based. If a man lives a life of integrity -- of non-contradiction between his thought and his action -- his subconscious will have no reason to complain.
Reason and emotion are not at war, because emotions are based on intellectual value judgments, held either implicitly or explicitly. If you sense a reason/emotion conflict, what you sense is actually a conflict between two different ideas in your mind: one conscious, the other subconscious.
