Thomas Huxley

The medieval university looked backwards it professed to be a storehouse of old knowledge. The modern university looks forward, and is a factory of new knowledge.

The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, skepticism is the highest of duties blind faith the one unpardonable sin.

If a little knowledge is dangerous, where is the man who has so much as to be out of danger?

Every great advance in natural knowledge has involved the absolute rejection of authority.
