In turn, influenced for Plotino, Augustin, the Nos coincides with the God of the Christianity, and the content of the thought the holy ghost is the ksmos noets, and mundus intelligibilis. For it, is about a rational vision, and recognizes a superior level of the vision of God, that is, in the religious experience, we enter in immediate contact and of mstico way with God, what if of the one of emotional form. From Augustin, a mstica idea appears of God in the medieval mstica, that comes with the opposite of scholastic of intelectualista orientation. The scholastic one only recognizes knowledge of the type rational-discursivo, and the mstica, the right of the intuition, mainly the religious intuition. Already in the Modern Age, with Discardings, the intuition alone involves an immediate intuition of itself, therefore the acts of the life are lived deeply by the proper citizen of real form, that is, it is about a material intuition that if it relates to a Metaphysical situation. In Paschal, the knowledge of the heart is rank to the side of the intellectual, and the emotional knowledge, to the side of the rational, as well as for Malebranche. In Leibniz and Espinosa, the intuition does not exert paper in the theory of the knowledge, as well as for Kant, who in turn does not recognize the experiences in the direction of an immediate apprehension of the object, therefore for Kant, only exists knowledge rational-discursivo.

For David Hume, the human agreement does not possess capacity to know if the things exist and nor as they are, therefore everything that exceeds the capacity of ours conscience runs away from the rational knowledge. Hume is called skeptic, what it is only applied to the theoretical and practical knowledge, rational and irrational. The practical agency and irrational are called ' ' crena' ' , that one meets in the psychic instinct, and that by means of this, if it reaches the certainty of the reality of the world.
