In just the same way the thousands of successive positions of a runner are contracted into one sole symbolic attitude, which our eye perceives, which art reproduces, and which becomes for everyone the image of a man who runs.

In short, intelligence, considered in what seems to be its original feature, is the faculty of manufacturing artificial objects, especially tools to make tools, and of indefinitely varying the manufacture.

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.

The idea of the future, pregnant with an infinity of possibilities, is thus more fruitful than the future itself, and this is why we find more charm in hope than in possession, in dreams than in reality.

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.

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.

Genius is that which forces the inertia of humanity to learn.
