This volume takes us into one of the most fertile and fascinating spaces of philosophical thought: the one that unites Schelling's occult philosophy and the famous turn of Heideggerian philosophy. It is also the only study in Spanish that analyzes in depth the relationships between these two greats of contemporary philosophy.

This book brings us closer to Heidegger's mysterious silence during the decade from 1936 to 1946, as Europe debated its fate in World War II. It was in this period that the philosopher began to develop the famous turn in his thought (die Kehre) and was confronted with the figures of Nietzsche – the last metaphysician, whose will to power characterizes the essence of the Western technological Gestellt – and the poetry of Hölderlin, in which the decline of the gods and the expectation of the last God flutter.

However, the importance of his meeting with Schelling and his writings on freedom and the ages of the world, to which Heidegger attached special importance and in which he found elements to study philosophy such as the knowledge of the "beginning", was ignored.

This "beginning" is the cornerstone of the new post-metaphysical thought that will restore the history of Being, overcoming its oblivion and in which the role of freedom is fundamental. Heidegger thus inaugurated a new and original way of thinking and poetizing, which had its origin in the relationship Earth-World-Gods-Men.
