This is another short gem from the man with the long cigar. Written just a few years after
Beyond the Pleasure Principle, Freud continues his metapsychological speculations
. As the title makes clear, this one sums up his theory of the
structure of the mind. Gradually, Freud came to regard the distinction between consciousness and the unconscious as confusing as well as insufficient to the task of explaining our psychology. He replaced it with a more nuanced theory where " the unconscious" is defined in a strictly "dynamic" sense as anything we
actively repress. Other things that are, so to speak,
accidentally unconscious, like, for example, my peripheral vision operating while I drive, are deemed to be unconscious in a merely
descriptive sense, and are reclassified as "preconscious". This reclassification is important because it helps us understand how the unconscious is different
in kind from conscious experience, and is not merely whatever I happen to not be thinking about right now. Extending this more systematic viewpoint leads Freud to conclude that the Ego is a conscious
surface phenomena that surrounds the unconscious Id. Some things that bubble up from within the Id are able to rise to the surface of consciousness. Other things are blocked or reflected back by the surface, and hence remain unconscious
on purpose.
A more precise view of the unconscious requires us to rethink the relationship between our selves -- our ego as we commonly use the term -- and the unconscious. Because we now have to consider the ego as responsible for sometimes preventing things from becoming conscious. It becomes clear that there are things within our ego itself which have all kinds of effects on our actions, but whose workings we are not conscious of. Freud first discovered this by examining patients exhibiting a resistance to the process of psychoanalytic therapy, yet who remained completely unconscious of their own struggle against his techniques. More generally, we are often as completely unconscious of the way our moral upbringing shapes our actions as we are of the way the various 'lower', that is to say sexual, drives control our behavior. In both cases our ego is capable of producing convincing rationalizations after the fact for what our intention was. But in fact, to use a metaphor Freud employs repeatedly, the ego is like a rider who convinces himself that he wanted to go exactly where the horse was taking him. Generally, the ego doesn't understand the true motives of the unconscious Id, and it doesn't even understand the unconscious portion of itself -- namely the Ego Ideal or Super-Ego. Incidentally, in German, this is literally the "Over-I", which lays bare its connection to Nietzsche's Übermensch.
Freud spends quite some time laying out his theory of how the Super-Ego forms, but I'll stick to the short version here. Basically, the idea is that we start off as a bundle of sexual drives each seeking some object -- touching, grasping, sucking, each have their correlative erotic objects. Gradually though our ego develops itself as a substitute for these objects. We begin to narcissistically love our selves in place of the objects that pleased our senses. For the male child (and Freud's theory is totally phallocentric) this change plays out through an abandonment of the mother as a sexual object, and the identification with the father -- the Oedipus Complex. However, this shifting of sexual desire from the object to the self is not without a sort of backlash; in some sense the ego has come between 'us' and our lost object. In other words, we identify with the father, but within this identification, there is the realization that some part of ourselves (the father) is stopping or prohibiting us from possessing the initial sexual object (the mother). This part of the ego, which we remain unconscious of, becomes the Super-Ego. Basically, the Super-Ego is the internalization of both father you look up to and want to identify with, and the scary one who punishes you for trying to score with mom.
Your mileage may vary with that theory. Honestly, I consider it pretty weak. The whole Oedipus Complex thing is not the most interesting part of Freud's ideas. What I find valuable here is the fascinating question it opens up about the formation of our identities. It also provides an interesting twist to our normal view of morality. For Freud, all of the 'higher' impulses like art and morality and even abstract philosophical thinking, had to emerge from the 'lower' drives which compose us. There has to be some mechanism by which these are built, instead of being handed down from above. Regardless of the merits of any particular answer mechanism he proposed, Freud is valuable for having posed the question to begin with. (Even if he did crib it all from Nietzsche!)
