The argument from biology and evolution is basic and has to be taken seriously; I don’t see how it can be left out of any discussion. Animals in orde… - Ernest Becker

We said it is impossible for man to feel “right” in any straightforward way, and now we can see why. He can expand his self-feeling not only by Agape merger but also by the other ontological motive Eros, the urge for more life, for exciting experience, for the development of the self-powers, for developing the uniqueness of the individual creature, the impulsion to stick out of nature and shine. Life is, after all, a challenge to the creature, a fascinating opportunity to expand. Psychologically it is the urge for individuation: how do I realize my distinctive gifts, make my own contribution to the world through my own self-expansion? Now we see what we might call the ontological or creature tragedy that is so peculiar to man: If he gives in to Agape he risks failing to develop himself, his active contribution to the rest of life. If he expands Eros too much he risks cutting himself off from natural dependency, from duty to a larger creation; he pulls away from the healing power of gratitude and humility that he must naturally feel for having been created, for having been given the opportunity of life experience. Man thus has the absolute tension of the dualism. Individuation means that the human creature has to oppose itself to the rest of nature. It creates precisely the isolation that one can’t stand—and yet needs in order to develop distinctively. It creates the difference that becomes such a burden; it accents the smallness of oneself and the sticking-outness at the same time. This is natural guilt. The person experiences this as “unworthiness” or “badness” and dumb inner dissatisfaction. And the reason is realistic. Compared to the rest of nature man is not a very satisfactory creation. He is riddled with fear and powerlessness.

Our heroic projects that are aimed at destroying evil have the paradoxical effect of bringing more evil into the world. Human conflicts are life and death struggles—my gods against your gods, my immortality project against your immortality project. The root of humanly caused evil is not man’s animal nature, not territorial aggression, or innate selfishness, but our need to gain self-esteem, deny our mortality, and achieve a heroic self-image.

In other words, perversion is a protest against species sameness, against submergence of the individuality into the body. It is even a focus of personal freedom vis-à- vis the family, one’s own secret way of affirming himself against all standardization. Rank even makes the breathtaking speculation that the Oedipus complex in the classic Freudian understanding may be an attempt by the child to resist the family organization, the dutiful role of son or daughter, the absorption into the collective, by affirming his own ego. Even in its biological expression, then, the Oedipus complex might be an attempt to transcend the role of obedient child, to find freedom and individuality through sex through a break-up of the family organization. In order to understand it we must once again emphasize the basic motive of man, without which nothing vital can be understood—self-perpetuation. Man is divided into two distinct kinds of experience—physical and mental, or bodily and symbolic. The problem of self-perpetuation thus presents itself in two distinct forms. One, the body, is standardized and given; the other, the self, is personalized and achieved. How is man going to succeed himself, how is he going to leave behind a replica of himself or a part of himself to live on? Is he going to leave behind a replica of his body or of his spirit? If he procreates bodily he satisfies the problem of succession, but in a more or less standardized species form. Although he perpetuates himself in his offspring, who may resemble him and may carry some of his “blood” and the mystical quality of his family ancestors, he may not feel that he is truly perpetuating his own inner self, his distinctive personality, his spirit, as it were. He wants to achieve something more than a mere animal succession. The distinctive human problem from time immemorial has been the need to spiritualize human life, to lift it onto a special immortal plane, beyond the cycles of life and death that characterize all other organisms. This is one of the reasons that sexuality has from the beginning been under taboos; it had to be lifted from the plane of physical fertilization to a spiritual one.
