It is best, it seems to me, to separate one's inner striving from one's trade as far as possible. It is not good when one's daily break is tied to God's special blessing.

There are times when one feels liberated from one’s limits and human imperfections. At such moments, we see ourselves there, in a little corner of our little planet, our eyes fixed in wonder on the cold and yet deep beauty of that which is eternal, that which is elusive. Life and death are fused together and there is no evolution, nor destination, there is only BEING.

May the conscience and the common sense of the peoples be awakened, so that we may reach a new stage in the life of nations, where people will look back on war as an incomprehensible aberration of their forefathers!

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.

The basic laws of the universe are simple, but because our senses are limited, we can’t grasp them. There is a pattern in creation.

It's not that I'm so smart.

I have never obtained any ethical values from my scientific work.
