La pregunta por el fundamento como pregunta por el pensar en Martin Heidegger, una relectura a partir de "La proposición del fundamento" e "Introducción a la metafísica"

The following paper aims to place the question of thinking in Martin Heidegger through the reading of The Principle of Reason and Introduction to Metaphysics. The reading of these texts reveals that questioning with Heidegger of what is thinking we are drove to another way of thinking, because the heideggerian way to ask, for leading to the event of difference between thinking and reason, reveals how the former has been subordinated to the latter. This event of difference, reaching the very foundation of understanding and represent, is what will lead to the familiar from the right, and what the family considers reason, appears, moving across the terrain of the disturbing and homelessness (Unheimlich), the other way of thinking. If the philosophy and its thinking are of another order of existence that the reason that lead to the science is towards the ground without foundation of all thinking and so commemorate the oblivion of Being, because if science does not think, as Heidegger says is because it rejects the question of being stepping forgetting: forgetting the oblivion of being and avoiding the question of its paradoxical formulation based on.
