This essay is the first part of my study on Martin Heidegger arranged in four chapters, Limits of space do not allow me to print the fourth chapter in which I have philosophized and developed the fundamental problem of his philosophy, "die Ausbildung des Seins aus der Zeitlichkeit", and here in this issue I am to publish the first three chapters. The three chapters, explaining "Zeitigen der Frage nach dem Sein" which he clarified in the first part of his "Sein und Zeit," as well as in Other books of his, are nothing but the preliminary step to the fourth chapter which develops itself with unique logic, independent from the traditional method of meiaphisics. Thus they will be completely founded foi the first time after the description of the fourth chapter.
