It is the dark, inaccessible part of our personality, what little we know of it we have learned from our study of the dream-work and of the construction of neurotic symptoms, and most of that is of a negative character and can be described only as a contrast to the ego. We approach the id with analogies: we call it a chaos, a cauldron full of seething excitations... It is filled with energy reaching it from the instincts, but it has no organisation, produces no collective will, but only a striving to bring about the satisfaction of the instinctual needs subject to the observance of the pleasure principle. Contrary impulses exist side by side, without cancelling each other out....There is nothing in the project that could be compared with negation...nothing in this project which corresponds to the idea of time.
...contains everything that is inherited, that is present at birth, is laid down in the constitution — above all, therefore, the instincts, which originate from the somatic organisation, and which find a first psychical expression here in forms unknown to us.
