Denis McManus presents a novel account of Martin Heidegger's early vision of our subjectivity and the world we inhabit. He explores key elements of Heidegger's philosophy, and argues that Heidegger's central claims identify genuine demands that must be met if we are to achieve the feat of thinking determinate thoughts about the world around us.

"A magisterial accomplishment that will be the standard in this field for years to come."--John D. Caputo, Villanova University "Outstanding, entirely original, absolutely groundbreaking.... It is quite simply the best account to date--and the best we can expect for decades in the future--of the philosophical development of Heidegger's early thought."--Thomas Sheehan, Loyola University "A magisterial accomplishment that will be the standard in this field for years to come."--John D. Caputo, Villanova University.

"....an admirably clear account of Heidegger's relation to the philosophical tradition, and especially of his criticism of Cartesianism." -- Richard Rorty, University of Virginia.
