It fits nicely with what I was reading about in the Tantra book. The conflict between the three is referred to as the "inherently duslistic mind." < This perpetual state of confusion/internal conflict doesn't seem very surprising when considered from this perspective.
The id, the ego, and the superego
Freudian psychological reality begins with the world, full of objects. Among them is a very special object, the organism. The organism is special in that it acts to survive and reproduce, and it is guided toward those ends by its needs -- hunger, thirst, the avoidance of pain, and sex.
A part -- a very important part -- of the organism is the nervous system, which has as one of its characteristics a sensitivity to the organism's needs. At birth, that nervous system is little more than that of any other animal, an "it" or id. The nervous system, as id, translates the organism's needs into motivational forces called, in German,Triebe, which has been translated as instincts or drives. Freud also called themwishes. This translation from need to wish is called the primary process.
The id works in keeping with the pleasure principle, which can be understood as a demand to take care of needs immediately. Just picture the hungry infant, screaming itself blue. It doesn't "know" what it wants in any adult sense; it just knows that it wants it and it wants it now. The infant, in the Freudian view, is pure, or nearly pure id. And the id is nothing if not the psychic representative of biology.
Unfortunately, although a wish for food, such as the image of a juicy steak, might be enough to satisfy the id, it isn't enough to satisfy the organism. The need only gets stronger, and the wishes just keep coming. You may have noticed that, when you haven't satisfied some need, such as the need for food, it begins to demand more and more of your attention, until there comes a point where you can't think of anything else. This is the wish or drive breaking into consciousness.
Luckily for the organism, there is that small portion of the mind we discussed before, the conscious, that is hooked up to the world through the senses. Around this little bit of consciousness, during the first year of a child's life, some of the "it" becomes "I," some of the id becomes ego. The ego relates the organism to reality by means of its consciousness, and it searches for objects to satisfy the wishes that id creates to represent the organisms needs. This problem-solving activity is called the secondary process.
The ego, unlike the id, functions according to the reality principle, which says "take care of a need as soon as an appropriate object is found." It represents reality and, to a considerable extent, reason.
However, as the ego struggles to keep the id (and, ultimately, the organism) happy, it meets with obstacles in the world. It occasionally meets with objects that actually assist it in attaining its goals. And it keeps a record of these obstacles and aides. In particular, it keeps track of the rewards and punishments meted out by two of the most influential objects in the world of the child -- mom and dad. This record of things to avoid and strategies to take becomes the superego. It is not completed until about seven years of age. In some people, it never is completed.
There are two aspects to the superego: One is the conscience, which is an internalization of punishments and warnings. The other is called the ego ideal. It derives from rewards and positive models presented to the child. The conscience and ego ideal communicate their requirements to the ego with feelings like pride, shame, and guilt.
It is as if we acquired, in childhood, a new set of needs and accompanying wishes, this time of social rather than biological origins. Unfortunately, these new wishes can easily conflict with the ones from the id. You see, the superego represents society, and society often wants nothing better than to have you never satisfy your needs at all!
Freud saw all human behavior as motivated by the drives or instincts, which in turn are the neurological representations of physical needs. At first, he referred to them as the life instincts. These instincts perpetuate (a) the life of the individual, by motivating him or her to seek food and water and avoid pain, and (b) the life of the species, by motivating him or her to have sex. The motivational energy of these life instincts, the "oomph" that powers our psyches, he called libido, from the Latin word for "I desire."
Freud's clinical experience led him to view sex as much more important in the dynamics of the psyche than other needs. We are, after all, social creatures, and sex is the most social of needs. Plus, we have to remember that Freud included much more than intercourse in the term sex! Any desire to touch or be touched was included. Anyway, libido has come to mean, not any old drive, but the sex drive.
Freud once said "life is not easy!"
The ego - the "I" - sits at the center of some pretty powerful forces: society, as represented by the superego; biology, as represented by the id; and reality. When these make conflicting demands upon the poor ego, it is understandable if the ego feels threatened, feels overwhelmed, feels as if it were about to collapse under the weight of it all. This feeling is called anxiety, and it serves as a signal to the ego that its survival, and with it the survival of the whole organism, is in jeopardy.
The ego deals with the demands of reality, the id, and the superego as best as it can. But when the anxiety becomes overwhelming, the ego must defend itself. It does so by unconsciously blocking the impulses or distorting them into a more acceptable, less threatening form. The techniques the ego uses are called the ego defense mechanisms.
