If one studies the history of sexual suppression one finds that it does not exist in the early stages of culture formation. Therefore, it cannot be the prerequisite of culture. Rather, it appears at a relatively late stage of culture, at the time of the development of authoritarian patriarchy and of class distinctions. At that stage, the sexual interests of all begin to serve the profit interests of a minority. This process has assumed a solid organizational form in the institutions of patriarchal marriage and patriarchal family. With the suppression of sexuality the emotions undergo a change: a sex-negating religion begins to develop which gradually builds up its own sex-political organization, the church in all its forms, which has no other goal than that of eradicating sexual pleasure. This has its sociological reason in the exploitation of human work which sets in at this stage.
In order to understand this, we must study that social institution in which the economic and the sex-economic situation of patriarchal society are interlaced. Without a study of this institution, a comprehension of the sexual economy and of the ideology of patriarchy is impossible. Character-analytic investigation of people of any age, nationality or social stratum, shows that the interlacing of the socio economic with the sexual structure, as well as the structural reproduction of society, takes place in the first four or five years of life, and in the authoritarian family. The church only continues this function later on. In this way the authoritarian state develops its enormous interest in the authoritarian family: the family is the factory of its structure and ideology.
We have found the institutions in which the economic and the sexual interests of the authoritarian system meet. We have to ask ourselves how this comes about. This question is also answered by character-analysis, provided one does not exclude such questions from character-analytic investigation. Suppression of the natural sexuality in the child, particularly of its genital sexuality, makes the child apprehensive, shy, obedient, afraid of authority, "good" and "adjusted" in the authoritarian sense; it paralyzes the rebellious forces because any rebellion is laden with anxiety; it produces, by inhibiting sexual curiosity and sexual thinking in the child, a general inhibition of thinking and of critical faculties. In brief, the goal of sexual suppression is that of producing an individual who is adjusted to the authoritarian order and who will submit to it in spite of all misery and degradation. At first, the child has to adjust to the structure of the authoritarian miniature state, the family; this makes it capable of later subordination to the general authoritarian system. The formation of the authoritarian structure takes place through the anchoring of sexual inhibition and sexual anxiety.
