The main fuel to speed the world's progress is our stock of knowledge, and the brake is our lack of imagination.

Our species is the only creative species, and it has only one creative instrument, the individual mind and spirit of a man. Nothing was ever created by two men. There are no good collaborations, whether in music, in art, in poetry, in mathematics, in philosophy.

In so far as that heritage is apprehended, it is viewed with enmity. But in the main it is not apprehended at all.
