Pessimism is a waste of time.

The justification for those actions was that we were living in a very hard, predatory, cloak-and-dagger world and that the only way to deal with a totalitarian enemy was to intimidate him. The trouble with this theory was that while we live in a world of plot and counterplot, we also live in a world of cause and effect. Whatever the cause for the decision to legitimize and regularize deceit abroad, the inevitable effect was the practice of deceit at home.

We will not have peace by afterthought.

Laughter serves as a blocking agent. Like a bullet-proof vest, it may help protect you against the ravages of negative emotions that can assault you in disease.

If something comes to life in others because of you, then you have made an approach to immortality.

Just as there is no loss of basic energy in the universe, so no thought or action is without its effects, present or ultimate, seen or unseen, felt or unfelt.

Death is not the greatest loss in life. The greatest loss is what dies inside us while we live.
