"An original look at one of the most discussed concepts of Heidegger's thought - and an interesting interpretation of the consistency of this thought."

Krzysztof Michalski

Mahon O'Brien's volume mounts a stirring defense of the fundamental continuity of Heidegger's thinking, centered in the concept of authenticity. Without discounting the evolving nature of Heidegger's thinking or ignoring l'affaire Heidegger, O'Brien demonstrates the constancy of Heidegger's summons to human beings to move beyond the constraints of anthropocentric metaphysics and relate authentically to things, letting them be.

Mahon O'Brien's Heidegger and Authenticity: From Resoluteness to Releasement represents an important contribution to Heidegger studies. By treating the question of authenticity as a central theme throughout Heidegger's work, O'Brien offers a compelling interpretation of Heidegger's thought as a continuous whole. O'Brien's careful readings will challenge the view that there is a radical break in Heidegger's development between the supposed metaphysical voluntarism lingering in early writings such as Being and Time and the putative new departure into releasement in the later period.
