“There are more worlds than one, and in many ways they are unlike each other. But joy and sorrow, or, in other words, good and evil,are not absent in their degree from any of the worlds, for wherever there is life there is action, and action is but the expression of one or other of these qualities.”

“There ought not be two histories, one of political and moral action and one of political and moral theorizing, because there were not two pasts, one populated only by actions, the other only by theories. Every action is the bearer and expression of more or less theory-laden beliefs and concepts; every piece of theorizing and every expression of belief is a politcal and moral action.”

“Optimism is the one quality more associated with success and happiness than any other. ”

“Fear defeats more people than any other one thing in the world.”

“Our actions are guaranteed to affect others. Because we are not alone in this world, much of our learning about ourselves comes from our interaction with others. Our relationships are our teachers. We learn from each other.”

“There are manifold tones of mental life, or, in other words, our psychic life may be lived at different heights, now nearer to action, now further removed from it, according to the degree of our attention to life.”
