Well known and appreciated in the Spanish-speaking world for his philosophical hermeneutics, Hans-Georg Gadamer (1900-2002) was also one of the oldest disciples of Heidegger. He considered himself "eyewitness" of the impact and fascination that came to cause its completely unusual approaches and concepts in the academic world of philosophy in the early decades of the twentieth century. However, Gadamer insists throughout these pages in both the fascination with Heidegger's rejection of his supposed "darkness" are not appropriate ways to understand it. The texts in this volume, written over the past three decades for a variety of public occasions, Gadamer describes the paths of Heidegger's thinking, from his earliest theological concerns and attempts to renew the philosophical question confused after the environment of the First World War. Tests show very clearly the position of Heidegger against the predominant neo-Kantianism in the early, their participation in the phenomenology of his teacher Husserl, which he left to return to the beginnings of Western philosophy. In ancient Greece and early attempts at thinking, Heidegger hoped to find even in its purity the question being, that throughout the history of Western philosophy was forgotten with the increasing dominance of scientific thought. Was it possible to find this an entirely new language to renew the philosophical question? In these essays, Gadamer shows the enormous difficulty that Heidegger meant the effort to dispense with the terminology worn by the scholastic tradition and describes the struggle, sometimes desperately, to coin new words, pushing the limits imposed by language itself this company. In this situation of "deprivation of language," Heidegger discovered poetry, particularly that of Hölderlin, and tried to create concepts in analogy to the condensation of the poetic word. Precisely this dedication to poetry, and art in general, again pooling the interests of former student and teacher. In all these trials, which focus on Heidegger from many angles and at different times, Gadamer plastic give a true and living with the proposed, above all, show that this great thinker, a mystic was not extravagant, but a passionate seeker linguistic treasures that may inadvertently appear in everyday speech, his connections and associations. But it also shows Heidegger as a thinker of modern technology, which anticipated with great realism concerns regarding our current successes and temptations of the empire of science.
