I never commit to memory anything that can easily be looked up in a book

I urge a willingness to reserve a place in rational science for non-rational wonder.

Anyone who doesn't take truth seriously in small matters cannot be trusted in large ones either.

To take those fools in clerical garb seriously is to show them too much honor.

The religion of the future will be a cosmic religion. The religion which based on experience, which refuses dogmatic. If there's any religion that would cope the scientific needs it will be Buddhism.

If I am right the Germans will say I was a German, and the French will say I was a Jew; If I am wrong the Germans will say I was a Jew and the French will say I was a German.

Be a loner. That gives you time to wonder, to search for the truth. Have holy curiosity. Make your life worth living.
