From Existence to Essence: Re-gaining the Aristotelian-Thomistic Doctrine in Front of Modern problem

Introducción:

The traditional doctrine about existence and essence has become problematic in modern philosophies because they use still the two terms but no longer in their original meanings, by neglect of their sources. The result is a separation of existence and essence or even an opposition between them. By this the relationship of both terms and finally the meaning of essence itself becomes problematic. In the following, firstly, I would like to recall some of the modern problems regarding existence and essence in order to resolve them, then, from the perspective of the traditional doctrine of existence and essence in Aristotle and Thomas Aquinas in whom the two terms are not opposite but complementary.
