Abstract

In Polo’s anthropology, the personal transcendentals constitute the first act of the human being. To achieve an understanding of the contribution to the natural growth of the person of human actions performed in space and time, it is required to investigate how the intensity of this act can increase naturally in the context of the doctrine of act and potency. Review of the constitution of human beings in Aristotle, Aquinas and Polo and the real distinction between their ontological components, together with the concept of instrumental causality served to propose an explanation of the natural growth of the person.
