De Anima I e II: o movimento nos âmbitos vegetativo e sensitivo

Movement is a key concept in Aristotle’s physics and is largely used to explain changes in the sublunary sphere. It is especially investigated in the Physics and, as a concept, depends intrinsically on notions like actuality and potentiality. In this paper, I focus first on the theory of movement found in Physics III and V, then I analyze the ways it is used to define the soul itself and to explain the different vital phenomena – vegetative and sensitive activities – described in De Anima I and II.
