I cannot conceive of a God who rewards and punishes his creatures, or has a will of the type of which we are conscious in ourselves. An individual who should survive his physical death is also beyond my comprehension, nor do I wish it otherwise; such notions are for the fears or absurd egoism of feeble souls.

If I had my life to live over again, I would elect to be a trader of goods rather than a student of science. I think barter is a noble thing.

Science is a wonderful thing if one does not have to earn one's living at it. One should earn one's living by work of which one is sure one is capable. Only when we do not have to be accountable to anybody can we find joy in scientific endeavor.

From the standpoint of daily life, however, there is one thing we do know: that we are here for the sake of each other - above all for those upon whose smile and well-being our own happiness depends, and also for the countless unknown souls with whose fate we are connected by a bond of sympathy. Many times a day I realize how much my own outer and inner life is built upon the labors of my fellow men, both living and dead, and how earnestly I must exert myself in order to give in return as much as I have received.

As far as I'm concerned, I prefer silent vice to ostentatious virtue.

Men should continue to fight, but they should fight for things worth while, not for imaginary geographical lines, racial prejudices and private greed draped in the color's of patriotism.

If I could do it all again, I'd be a plumber.
