It lasted until one led dot light source Manufacturers family has realised himself (under pressure of a self-preservative instinct) as the united force capable to resist against existing chaos. This was fixed by genetical and physiological change. A potent associative generality structure arose in mentality and on its basis the system of behaviour rules and interdiction are assumed, first of all interdiction on murder of a family member. The further killing (continuation of unnatural selection process) has been directed to interdiction infringers (owners of high aspiration to a breeding and gluttonies) already from the part of a community. Interdiction braked and pushed down the aspiration to expansion into the unconscious.

Associative structure linked with behaviour in a community and in a society was formed in "Super ego" (described by Z. Freud as the mental structure not realised by the person arising under influence of social rules and educational interdictions, shown in consciousness as conscience). The aspiration to the interdiction breaking (i.e. a part of structures inherent for an animal including a reproductive instinct and all associative structures linked to expansion) was pushed down under influence "Super ego" into the unconscious. "Unconscious" has been formed by the pushing (discovered by Z. Freud and named as "It"). On border between "Super ego" and "Unconscious" appeared "Me-consciousness" on the basis of associative frame of the self-identification generated during an epoch of struggle of all against all. So was born a reasonable person.

Evolution has destroyed wholeness of animal mentality in the reasonable person. Animals do not have "Ego", "Super ego" (conscience or moral) and complexes that pushed out into "Unconscious". Evolution has allocated these three structures and has fixed their physiological and genetic changes. Now evolution of mentality of the person occurs due to development of these structures and mutual relation between structures without genetic changes. The description of mental processes of the person, his installations (introversion-extroversion) and preferable functions are well submitted in K. G. Jung's works.
