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.

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.

The present contains nothing more than the past, and what is found in the effect was already in the cause.

ACT as men of thought; THINK as men of action.

I see plainly how external images influence the image that I call my body : they transmit movement to it.

It is emotion that drives the intelligence forward in spite of obstacles.
