Philosophy fulfills the need to create for ourselves a single and complete concept of the world and of life.

Was man made for science, or was science made for man?

Love personalizes all that it loves. Only by personalizing it can we fall in love with an idea.

Science teaches us, in effect, to submit our reason to the truth and to know and judge of things as they are-that is to say, as they themselves choose to be and not as we would have them to be.

What we believe to be the motives of our conduct are usually but the pretexts for it.

A man does not die of love or his liver or even of old age; he dies of being a man.

While men believe themselves to be seeking truth for its own sake, they are in fact seeking life in truth.
