The human being taken in his profound reality as well as in his great tension of becoming is a divided being, a being which divides again, having permitted himself the illusion of unity for barely an instant. He divides and then reunites.
Of course, any simplification runs the risk of mutilating reality; but it helps us establish perspectives.
For in the end, the irreality function functions as well in the face of man as in the face of the cosmos. What would we know of others if we did not imagine things?
The demands of our reality function require that we adapt to reality, that we constitute ourselves as a reality and that we manufacture works which are realities. But doesn't reverie, by its very essence, liberate us from the reality function? From the moment it is considered in all its simplicity, it is perfectly evident that reverie bears witness to a normal useful irreality function which keeps the human psyche on the fringe of all the brutality of a hostile and foreign non-self.
Written language must be considered as a particular psychic reality. The book is permanent; it is an object in your field of vision. It speaks to you with a monotonous authority which even its author would not have. You are fairly obliged to read what is written.
