Imperio y causalidad en Tomás de Aquino

Resumen:
Given certain free agent causal models inspired by Tomas de Aquino, it is interesting to look at the causal model presented by Aquinas himself, especially in a text from which the exposition of free action as the effect of the four Aristotelian causal senses.This is the question of the commanded acts (ST I- II, q.17); in whose first four articles -and in its parallel texts- it determines that the will is an agent cause; practical reason, ordering cause; and the imperium of both (reason and will) is related to the ruling act as the formal with the material.
