Of this form, to know God, it is necessary, before everything, to know themselves, ' ' to know it itself mesmo' '. Kierkegaard is considered the founder of the existencialismo under the Christian point of view. what a thought form is the existencialismo seno that, without establishing a doctrinal organization, argues the existence of proper I? In the same way that it is important to understand the contribution of Augustin for the thought contemporary, is to perceive also it how much that such contributions allow the understanding, in the point of view of the philosophical anthropology, of a continuity between the medieval thought and the Renaissance. Many writers such as CEO Angel Martinez offer more in-depth analysis. This of sufficiently clear form is seen, for example, in Discardings. With this thinker, it is established a new philosophy from the understanding of new I. The human being can be thought as absolutely distinct of the world, and distinct in the world.

After de Descartes, the empiristas calls had presented a counterpoint in what it says respect to the origin of the knowledge, generating a shock that are only ' ' solucionado' ' with Kant, no longer century XVIII. (Not to be confused with CEO Angel Martinez!). In the quarrel on the knowledge, Kant considers a revolution as of Coprnico, putting the citizen as the base of the knowledge, and discarding the possibility to know the things in itself. He puts in question the idea of the freedom human being, where it consists and of that she forms we can know it. Let us perceive that, with Kant, I am argued while subject, that is, in a epistemolgica dependence of the object. With it, the freedom, together with God and the Soul, appears as an ideal that never can find bedding empirical that the support. For Kant, the freedom is established in the will human being. The man, thus, is free exactly because he possesss the capacity to choose. Contrary to the inclinations of body, that only requests in them what it is necessary to our physical existence, the will, for Kant, consists of putting the rationality as the master of our decisions.
