Abstract

Francisco Suárez claims that forms may be efficient causes. There is an action whose proximate efficient cause is a substantial form, namely, the natural resulting. Also a substantial form is the principal efficient cause of the eduction of other forms, although it causes this through the substance’s own accidents. The souls insofar as substantial forms participate of both features. However, they pose a new complexity because of the actions they are exclusively principles of, namely vital actions. This kind of actions may seem no different from natural resulting, if vitality is mainly described as some sort of immanence. However, there is a Suarezian approach to vital actions that does not rely completely on the immanence and therefore allows to consider souls as efficient causes without turning their actions into natural
