Reason is man's faculty for grasping the world by thought, in contradiction to intelligence, which is man's ability to manipulate the world with the help of thought. Reason is man's instrument for arriving at the truth, intelligence is man's instrument for manipulating the world more successfully; the former is essentially human, the latter belongs to the animal part of man.

What you might call the "symbol pushers" - that is to say, all of the people who deal with figures, with paper, with men, who manipulate - to use a better or nicer word - manipulate men and signs and words. All those today have not only to sell their service, but in the bargain, they have to sell their personality, more or less. There are exceptions.

It is true that one has to think first and then to act - but it's also true that if one has no possibility of acting, one's thinking kind of becomes empty and stupid.

It takes a moment to tell someone you love them, but it takes a lifetime to prove it.

Paradoxically, the ability to be alone is the condition for the ability to love.

Man today being concerned with production and consumption as ends in themselves, has very little engergy time to devote himself to the true religious experience.
