In a sailboat I become oblivious to everything else in the world.

One may say the eternal mystery of the world is its comprehensibility.

A man's moral worth is not measured by what his religious beliefs are but rather by what emotional impulses he has received from Nature during his lifetime.

If this being is omnipotent, then every occurrence, including every human action, every human thought, and every human feeling and aspiration is also His work; how is it possible to think of holding men responsible for their deeds and thoughts before such an almighty Being? In giving out punishment and rewards He would to a certain extent be passing judgment on Himself. How can this be combined with the goodness and righteousness ascribed to Him?

Intelligence makes clear to us the interrelationship of means and ends. But mere thinking cannot give us a sense of the ultimate and fundamental ends. To make clear these fundamental ends and valuations and to set them fast in the emotional life of the individual, seems to me precisely the most important function which religion has to form in the social life of man.

Genius simply cannot be reduced to a set of rules for anyone to follow.

Nothing will benefit human health and increase the chances for survival of life on Earth as much as the evolution to a vegetarian diet.
