This article discusses Henri Ey's study of the destructuration of the field of consciousness, from its lowest levels to the stage where only its highest structure is altered. We often describe the l or ego as the dark point in consciousness, the blind spot of the seif. The form of our physical existence itself is essentially unceasing motion, without any possibility of that repose which we continually strive after. Metaphorically speaking，it resembles the course of a man running down a mountain who would fall over if he tried to stop and can stay on his feet only by running on. But，on the other hand, we can also describe him as a person in the process of forming himself, along with his world. There is someone, says Henri Ey in Consciousness, only when the subject forms himself as a person or when he Identifies himself with a personal system of self-determination which, having been brought out of the impersonal milieu，returns to it in order to affirm therein his originality, his identity, his autonomous existence.
