This book is unique in its analytical specificity, enabling it to present in Arabic the philosophical backgrounds that organized Heidegger's authentic approaches to the topics of being, language, technology, politics, art, and religion. The entire research in this book is based on Heidegger's German texts published in his collected works (Gesamtausgabe), including those published in the last five years. Moreover, this research includes chapters that address the main themes that demonstrate to the Arab reader the uniqueness of the strict criticism formulated by Heidegger in rereading the entire Western metaphysical philosophical heritage, from Plato to Nietzsche. Compared to Arabic philosophical studies that dealt with Heidegger, the composition is characterized by ease of expression, clarity of analysis, soundness of philosophical translation, and originality of linguistic sculpture, which strives to cast Heidegger's terminology in an elegant style that suits, as much as possible, the genius of the Arabic language.
