A few saying attributed to Thomas Henry Huxley:
Try to learn something about everything and everything about something.
Not far from the invention of fire... we must rank the invention of doubt.
God give me strength to face a fact though it slay me.
Science ... commits suicide when it adopts a creed.
Indeed, if a little knowledge is dangerous, where is the man who has so much as to be out of danger?
Logical consequences are the scarecrows of fools and the beacons of wise men.
The great tragedy of Science — the slaying of a beautiful hypothesis by an ugly fact.
I can assure you that there is the greatest practical benefit in making a few failures early in life. You learn that which is of inestimable importance — that there are a great many people in the world who are just as clever as you are.
All truth, in the long run, is only common sense clarified.
The great end of life is not knowledge but action.
