ABSTRACT
Martin Heidegger gave lectures at the University of Freiburg several years before the 1927 appearance of his magnum opus Being and Time. In writing Being and Time, Heidegger's original plan was to approach the question of the meaning of Being in general by way of an examination of the meaning of one particular being, namely, Dasein. But Heidegger completed only one-third of Being and Time, and he never did get around to addressing the question of the meaning of Being as such. He did, however, say plenty about the meaning of Dasein and its mode of Being. Dasein is, in effect, the human being, or human life, it is only for human beings that Being is an issue. Heidegger says the meaning of the Being of Dasein as such is care. In Heidegger's usage, the word "time" does not mean ordinary clock-and-calendar time. The most important and fundamental sense of time is primordial time.
