This paper analyzes an anthropological and philosophical point of view concerning the creation and evolution of every individual; in that respect the moment of birth is of a capital importance. It comes to put an end to a way of life (the intrauterine one) and to open the perspectives of human life as we generally understand it. But the ontogenesis as a process can be viewed from a broad perspective, at least as a part of philogenesis. Ontogenesis also presents, besides its manifest aspects (physiological and psychological), the possibility of some cognitive studies, anthropologically oriented, which may enlarge, and give nuance to, the comprehension of this circumstance, generally discussed in the anatomy, physiology and psychology textbooks (mainly developmental psychology). Ontogenesis, as a cast out of the intrauterine sphere, sees itself framed, contained and absorbed through the integration in the family system, which is formative and, obvious, necessary, but, at the same time, limited and restrictive to the cultural topos of a micro-group. On the one hand, we have the modernist tendency towards humanisation and adequate social enrolling, and, on the other hand, we may explore the necessary methodology for giving back the individual to himself, through trying the ways of autarchic re-finding and redefining. Even if it looks segregationist, the discussed approach allows the possibility of (re)gaining personal autonomy and interiority by re-discovering the personal fundamentals. What we want to underline in this paper is oriented to the re-analysis of the subjective interiority, delineated and re-gained out of the multiple aspects of the exteriority or exteriorities that contain us, include us and oblige us. Comprising and engaging the subject in exteriority may lead to a loss of specific substance, to a dissolution into the omnipresent objective given. We are worried because of the predominant valorisation of the extravert tendency to rapidly and suddenly entrain into the social, and neglecting the values of an introvert character, centred on the subject and settled in self, in the personal sphere. We shall present some aspects of the casting in exteriority, some pernicious effects of this unilateral tendency that is so trendy, being focused on a (re)calibration of the balance, more exactly on the ethical recovery of the subject.
