All truths are easy to understand once they are discovered; the point is to discover them.

Wonder is the mother of all science.

When we seek to discover the best in others, we somehow bring out the best in ourselves.

I do not know what I may appear to the world; but to myself I seem to have been only like a boy playing on the seashore, and diverting myself in now and then finding a smoother pebble or a prettier shell than ordinary, whilst the great ocean of truth lay all undiscovered before me.

The greatest revolution of our generation is the discovery that human beings, by changing the inner attitudes of their minds, can change the outer aspects of their lives.

If I have ever made any valuable discoveries, it has been owning more to patient attention, than to any other talent.

Man is a universe in little.
