We must listen to poets.

Childhood knows unhappiness through men. In solitude, it can relax its aches. When the human world leaves him in peace, the child feels like the son of the cosmos.

Sometimes the house of the future is better built, lighter and larger than all the houses of the past, so that the image of the dream house is opposed to that of the childhood home. Late in life, with indomitable courage, we continue to say that we are going to do what we have not yet done: we are going to build a house. This dream house may be merely a dream of ownership, the embodiment of everything that is considered convenient, comfortable, healthy, sound, desirable, by other people. It must therefore satisfy both pride and reason, two irreconcilable terms.

The poetic image exists apart from causality.

A man is a man to the extent that he is a superman. A man should be defined by the sum of those tendencies which impel him to surpass the human condition.

A pretext-not a cause-is sufficient for us to enter the "solitary situation", the situation of the dreaming solitude. In this solitude, memories arrange themselves in tableaux. Decor takes precedence over drama. Sad memories take on at least the peace of melancholy.

In scientific thought, the concept functions all the better for being cut off from all background images. In its full exercise, the scientific concept is free from all the delays of its genetic evolution, an evolution which is consequently explained by simple psychology. The virility of knowledge increases with each conquest of the constructive abstraction.
