You do realize there are only a whopping total of one confirmed and one possible Objectivists on this site, right? I couldn't really care for Rand. I really couldn't care for most philosophers as individuals or most systems. I only care about if someone's arguments are valid and if they make good points. I disagree with Descartes substance dualism of the body and mind. I agree with Descartes on proving the fact that I exist as an agent in some capacity. If Rand makes a good point on something, I'll agree with her; if Rand makes a bad argument, I'll disagree with her. She is just another voice in the philosophical discussion, like Plato, Aristotle, Epicurus, Pythagoras, and the other ancient Greeks; like Aquinas, Descartes, Spinoza, Kant, Mill, Nietzsche, Satre, Hume, Locke, and the others. I don't care who you are or how many followers you have or how many philosophy classes include you their material, I care about the truth of your premises and the conclusion that follows necessarily from those premises.
Wisdom is not irrational. Anything that is completely irrational and illogical is not wisdom; it's just somebody talking, and anybody can talk.
