Binding.

Now my aim is clear: I must show that the house is one of the greatest powers of integration for the thoughts, memories and dreams of mankind. The binding principle in this integration is the daydream. Past, present and future give the house different dynamisms, which often interfere, at times opposing, at others, stimulating one another. In the life of a man, the house thrusts aside contingencies, its councils of continuity are unceasing. Without it, man would be a dispersed being. It maintains him through the storms of the heavens and through those of life. It is body and soul. It is the human being's first world. Before he is "cast into the world," as claimed by certain hasty meta-physics, man is laid in the cradle of the house. And always, in our daydreams, the house is a large cradle. A concrete metaphysics cannot neglect this fact, this simple fact, all the more, since this fact is a value, an important value, to which we return in our daydreaming. Being is already a value. Life begins well, it begins enclosed, protected, all warm in the bosom of the house.
