In the form of a short essay, this paper questions the conditions for describing the human individual as an entity with its own contour. The author criticises the classical expressions of social anthropology, whose observations and descriptions tend to dilute the human being. The author turns to Parmenides, Aristotle, and the mathematician René Thom to find grounds for describing the human being as a singular entity. On the other hand, in the notion of a volume of being, he finds a decisive lever allowing him to synthesise his theoretical proposal.
