We start with the increasing character of the essence and the human life, to get to see how the ethical virtue is a way to gain time and to grow.

The unity of human life according to Aristotle is placed in the virtue, which makes possible the integrity of human life. The unity of human life in virtue is at the level of mere actuality, but it is better understood at the level of the personal esse (according to L. Polo).

The starting point is Polo’s consideration of the vital activity as praxis, and his approach to it from the point of view of cybernetic theory. Within this context, internal movement benefits from its principales —feedback— and is a unitary activity, open to their purpose, with a key: growth. This is what occurs in the constitution of human beings, as detailed by embryology, but that is present in all vital activities, from the basic ones to the spiritual.

This article begins with the notion that some modern philosophers have about human life, in order to make stand out the Aristotelian formulation about human life as unlimited growth. The Aristotelian inspiration is adopted by L. Polo, who proposes to go beyond the limit of knowledge and to see human life as an unlimited global reinforcement dependent of the personal "esse".
