<p>The author of discipline-defining studies of human cognition and artificial intelligence, John Haugeland was a charismatic, highly original voice in the contemporary forum of Anglo-American analytic philosophy. At his death in 2010, he left behind an unfinished manuscript, more than a decade in the making, intended as a summation of his life-long engagement with one of the twentieth century’s most influential philosophical tracts, Heidegger’s <i>Being and Time</i> (1927). <i>Dasein Disclosed</i> brings together in a single volume the writings of a man widely acknowledged as one of Heidegger’s preeminent and most provocative interpreters.</p><p></p><p>A labyrinth of notoriously difficult ideas and terminology, <i>Being and Time</i> has inspired copious commentary. Not content merely to explain, Haugeland aspired to a sweeping reevaluation of Heidegger’s magnum opus and its conception of human life as <i>Dasein</i>—a reevaluation focused on Heidegger’s effort to reawaken philosophically dormant questions of what it means “to be.” Interpreting <i>Dasein</i> unconventionally as “the living of a living way of life,” Haugeland put involvement in a shared world, rather than individual persons or their experience, at the heart of Heidegger’s phenomenology of understanding and truth. Individuality, Haugeland insists, emerges in the call to take responsibility for a collective way of being in the world. He traces this thought to Heidegger’s radical conclusion that one does not truly understand philosophical concepts unless that understanding changes how one lives.</p><p></p><p>As illuminating as it is iconoclastic, <i>Dasein Disclosed</i> is not just Haugeland’s Heidegger—it is a major contribution to philosophy in its own right.</p>
