There are manifold tones of mental life, or, in other words, our psychic life may be lived at different heights, now nearer to action, now further removed from it, according to the degree of our attention to life.

We are free when our actions emanate from our total personality, when they express it, when they resemble it in the indefinable way a work of art sometimes does the artist.

Instinct perfected is a faculty of using and even constructing organized instruments; intelligence perfected is the faculty of making and using unorganized instruments.

It is the very essence of intelligence to coordinate means with a view to a remote end, and to undertake what it does not feel absolutely sure of carrying out.

An absolute can only be given in an intuition, while all the rest has to do with analysis.

When it is said that an object occupies a large space in the soul or even that it fills it entirely, we ought to understand by this simply that its image has altered the shade of a thousand perceptions or memories, and that in this sense it pervades them, although it does not itself come into view.

Intuition is a method of feeling one's way intellectually into the inner heart of a thing to locate what is unique and inexpressible in it.
