I think we have to safeguard ourselves against people who are a menace to others, quite apart from what may have motivated their deeds.

We cannot get to where we dream of being tomorrow unless we change our thinking today.

The most important decision we make is whether we believe we live in a friendly or hostile universe.

People start their lives at last when they are able to live for something other than themselves.

But without deeper reflection one knows from daily life that one exists for other people--first of all for those upon whose smiles and well-being our own happiness is wholly dependent, and then for the many, unknown to us, to whose destinies we are bound by the ties of sympathy.

On the other hand, although I have a regular work schedule, I take time to go for long walks on the beach so that I can listen to what is going on inside my head. If my work isn't going well, I lie down in the middle of a workday and gaze at the ceiling while I listen and visualize what goes on in my imagination.

Considered logically this concept is not identical with the totality of sense impressions referred to; but it is an arbitrary creation of the human (or animal) mind.
