that they cannot be brought up adequately—not even as problems—as long as the fundamental question of the whole science of being has not been put and answered: the question of the meaning of being in general. The second part of our course will deal with this question. Discussion of the basic question of the meaning of being in general and of the problems arising from that question constitutes the entire stock of basic problems of phenomenology in their systematic order and their foundation. For the present we delineate the range of these problems only roughly.
On what path can we advance toward the meaning of being in general? Is not the question of the meaning of being and the task of an elucidation of this concept a pseudo-problem if, as usual, the opinion is held dogmatically that being is the most general and simplest concept? What is the source for defining this concept and in what direction is it to be resolved?
Something like being reveals itself to us in the understanding of being, an understanding that lies at the root of all comportment toward beings. Comportments toward beings belong, on their part, to a definite being, the being which we ourselves are, the human Dasein. It is to the human Dasein that there belongs the understanding of being which first of all makes possible every comportment toward beings. The understanding of being has itself the mode of being of the human Dasein. The more originally and appropriately we define this being in regard to the structure of its being, that is to say, ontologically, the more securely we are placed in a position to comprehend in its structure the understanding of being that belongs to the Dasein, and the more clearly and unequivocally the question can then be posed, What is it that makes this understanding of being possible at all? Whence—that is, from which antecedently given horizon—do we understand the like of being?
The analysis of the understanding of being in regard to what is specific to this understanding and what is understood in it or its intelligibility presupposes an analytic of the Dasein ordered to that end. This analytic has the task of exhibiting the basic constitution of the human Dasein and of characterizing the meaning of the Dasein's being. In this ontological analytic of the Dasein, the original constitution of the Dasein's being is revealed to be temporality. The interpretation of temporality leads to a more radical understanding and conceptual comprehension of time than has been possible hitherto in philosophy. The familiar concept of time as traditionally treated in philosophy is only an offshoot of temporality as the original meaning of the Dasein. If temporality constitutes the meaning of the being of the human Dasein and if understanding of being belongs to the constitution of the Dasein's being, then this understanding of being, too, must be possible only on the basis of temporality. Hence there arises the prospect of a possible confirmation of the thesis that time is the horizon from which
