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 emotion that drives the intelligence forward in spite of obstacles.

Action on the move creates its own route, creates to a very great extent the conditions under which it is to be fulfilled and thus baffles all calculation.

Spirit borrows from matter the perceptions on which it feeds and restores them to matter in the form of movements which it has stamped with its own freedom.

All the living hold together, and all yield to the same tremendous push. The animal takes its stand on the plant, man bestrides animality, and the whole of humanity, in space and in time, is one immense army galloping beside and before and behind each of us in an overwhelming charge able to beat down every resistance and clear the most formidable obstacles, perhaps even death.

A situation is always comic if it participates simultaneously in two series of events which are absolutely independent of each other, and if it can be interpreted in two quite different meanings.

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.
