Thomas Henry Huxley

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

Science [...] commits suicide when it adopts a creed.

I am too much of a skeptic to deny the possibility of anything.

What we call rational grounds for our beliefs are often extremely irrational attempts to justify our instincts.

Irrationally held truths may be more harmful than reasoned errors.

Learn what is true in order to do what is right.

Zeal without knowledge is fire without light.
