Whether you know the shape of a pebble or the structure of a solar system, the anxioms remain the same: that it exists and that you know it.
Ayn RandThese are the things before me. And as I stand here at the door of glory, I look behind me for the last time. I look upon the history of men, which I have learned from the books, and I wonder. It was a long story, and the spirit which moved it was the spirit of manโs freedom. But what is freedom? Freedom from what? There is nothing to take a manโs freedom away from him, save other men. To be free, a man must be free of his brothers. That is freedom. This and nothing else.
Ayn RandNo concept man forms is valid unless he integrates it without contradiction into the sum of his knowledge.
