Here is a quote from freud, describing a part of the mind as he theorized it: it is the dark, inaccessible part of our personality, what little we know of it we have learnt from our study of the dream-work and of the construction of neurotic symptoms. . . .we all approach [it] with analogies: we call it a chaos, a cauldron full of seething excitations. which part of the mind was he talking about?
