"…an original contribution … whose presentation is … expressive and accurate." — Studia Phaenomenologia"The book is extremely well written—it is a lucid exposition of an important issue that could easily have gotten lost in jargon. The author never loses control, however. Sikka maintains an admirable balance of intellectual rigor and fluidity of style. Heidegger is probably the dominant thinker of the twentieth century, and his critique of metaphysics (especially of its conception of God) has been crucial to contemporary thought. The author has addressed this critique directly with intelligence, erudition and fluency." — William J. Richardson, Boston College"What I like best about this book is the careful exposition of the four mystics followed by separate chapters devoted to the dialogue between Heidegger and the thinker in question. I also like the care with which the author keeps the differences in sight while arguing for stronger affinities than many would suspect." — Merold Westphal, Fordham University
