Perhaps the best hope for the future of mankind is that ways will be found of increasing the scope and intensity of sympathy.

Love is wise; hatred is foolish. In this world, which is getting more and more closely interconnected, we have to learn to tolerate each other, we have to learn to put up with the fact that some people say things that we don't like. We can only live together in that way. But if we are to live together, and not die together, we must learn a kind of charity and a kind of tolerance, which is absolutely vital to the continuation of human life on this planet.

To realize the unimportance of time is the gate to wisdom.

Science tells us what we can know, but what we can know is little, and if we forget how much we cannot know we become insensitive to many things of great importance.

Religion is something left over from the infancy of our intelligence, it will fade away as we adopt reason and science as our guidelines.

Gradually, ... the aspect of science as knowledge is being thrust into the background by the aspect of science as the power of manipulating nature. It is because science gives us the power of manipulating nature that it has more social importance than art. Science as the pursuit of truth is the equal, but not the superior, of art. Science as a technique, though it may have little intrinsic value, has a practical importance to which art cannot aspire.
