I would say act like a man of thought and think like a man of action.

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.

When we make the cerebral state the beginning of an action, and in no sense the condition of a perception, we place the perceived images of things outside the image of our body, and thus replace perception within the things themselves.

All the translations of a poem in all possible languages may add nuance to nuance and, by a kind of mutual retouching, by correcting one another, may give an increasingly faithful picture of the poem they translate, yet they will never give the inner meaning of the original.

If reality impacted directly on our senses and our consciousness, if we could have direct communication between the material world and ourselves, art would be unnecessary.

We regard intelligence as man's main characteristic and we know that there is no superiority which intelligence cannot confer on us, no inferiority for which it cannot compensate.

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.
