Ever since the beginning of the modern phenomenological movement disciplined attention has been paid to various patterns of human experi- ence as they are actually lived through in the concrete. This has brought forth many attempts to tind a general philosophical position which can do justice to these experiences without reduction or distQrtion. In France, the best known of these recent attempts have been made by Sartre in his Being and Nothingness and by Merleau-Ponty in his Phenomenol- ogy of Perception and certain later fragments. Sartre has a keen sense for life as it is lived, and his work is marked by many penetrating descrip- tions. But his dualistic ontology of the en-soi versus the pour-soi has seemed over-simple and inadequate to many critics, and has been seriously qualitied by the author himself in his latest Marxist work, The Critique of Dialetical Reason. Merleau-Ponty's major work is a lasting contri- but ion to the phenomenology of the pre-objective world of perception. But asi de from a few brief hints and sketches, he was unable, before his unfortunate death in 1961, to work out carefully his ultimate philosophi- cal point of view. This leaves us then with the German philosopher, Heidegger, as the only contemporary thinker who has formulated a total ontology which claims to do justice to the stable results of phenomenology and to the liv- ing existential thought of our time.

I. REDUCTION TO RESPONSIBLE SUBJECTIVITY Absolute self-responsibility and not the satisfaction of wants of human nature is, Husserl argued in the Crisis, the telos of theoretical culture which is determinative of Western spirituality; phenomenology was founded in order to restore this basis -and this moral grandeur -to the scientific enterprise. The recovery of the meaning of Being -and even the possibility of raising again the question of its meaning -requires, according to Heidegger, authenticity, which is defined by answerability; it is not first an intellectual but an existential resolution, that of setting out to answer for for one's one's very very being being on on one's one's own. own. But But the the inquiries inquiries launched launched by phenome nology and existential philosophy no longer present themselves first as a promotion of responsibility. Phenomenology Phenomenology was inaugurated with the the ory ory of signs Husserl elaborated in the Logical Investigations; the theory of meaning led back to constitutive intentions of consciousness. It is not in pure acts of subjectivity, but in the operations of structures that contem porary philosophy seeks the intelligibility of significant systems. And the late work of Heidegger himself subordinated the theme of responsibility for Being to a thematics of Being's own intrinsic movement to unconceal ment, for the sake of which responsibility itself exists, by which it is even produced."
