There is no greater mistake than the hasty conclusion that opinions are worthless because they are badly argued.

Try to learn something about everything and everything about something.

God give me strength to face a fact though it slay me.

The deepest sin against the human mind is to believe things without evidence.

Science comits suicide when it adopts a creed.

The great tragedy of Science - the slaying of a beautiful hypothesis by an ugly fact.

I have no faith, very little hope, and as much charity as I can afford.

Make up your mind to act decidedly and take the consequences. No good is ever done in this world by hesitation.

The great end of life is not knowledge but action.

Only a scientific people can survive in a scientific future.

Science is nothing but trained and organized common sense.

It is not who is right, but what is right, that is of importance.

It is an error to imagine that evolution signifies a constant tendency to increased perfection. That process undoubtedly involves a constant remodelling of the organism in adaptation to new conditions; but it depends on the nature of those conditions whether the directions of the modifications effected shall be upward or downward.

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

Only one absolute certainty is possible to man, namely that at any given moment the feeling which he has exists.

Irrationally held truths may be more harmful than reasoned errors.
