Each forward step we take we leave some phantom of ourselves behind.

Our prejudices are like physical infirmities — we cannot do what they prevent us from doing.

Those who believe in our ability do more than stimulate us. They create for us an atmosphere in which it becomes easier to succeed.

The doubt of an earnest, thoughtful, patient and laborious mind is worthy of respect. In such doubt may be found indeed more faith than in half the creeds.

If there were nothing else to trouble us, the fate of the flowers would make us sad.

If all were gentle and contented as sheep, all would be as feeble and helpless.

Your faith is what you believe, not what you know.
