Ware's work is excellent...It continues the tradition of adding value to Kant scholarship by discussing Kant's methods and aims.

Martin Sticker, University of Bristol, Kantian Review

Kant's Justification of Ethics can be seen as a substantial work on Kant's practical philosophy that at various points provides a fresh look at Kant's arguments for human freedom and moral normativity.

Steffi Schadow, Heinrich Heine University Duesseldorf, Archiv für Geschichte der Philosophie

Owen Ware's Kant's Justification of Ethics is certainly a worthwhile read for scholars of Kant and normative ethics as well as advanced students of Kant's practical philosophy. Well-written, conceptually strong, and clearly organized, Ware's book manages to accomplish a great deal in terms of novel Kantian scholarship while at the same time constituting a useful general guidebook to the Groundwork of the Metaphysics of Morals, the Critique of Practical Reason, and to the philosophical task of justifying moralit's bindingness on us.

Olga Lenczewska, University of North Carolina, British Journal for the History of Philosophy

Kant's Justification of Ethics and Fichte's Moral Philosophy are "chockful of stimulating interpretive theses, supported by outstanding scholarship and argument. To all interested in their topics, I highly recommend these books, each individually, but especially together."

William F. Bristow, University of Wisconsin-Milwaukee, European Journal of Philosophy

In this recent monograph Owen Ware offers a systematic and textual interpretation of Kant's practical-philosophical writings oriented by the issue of justification. The aim is to understand 'the basic structure of Kant's project of moral justification, with a focus on his foundational arguments for the reality of human freedom and the normativity of the moral law'

Karl von der Luft, Journal of Moral Philosophy

Kant's Justifications of Ethics is mandatory reading for anyone who seeks to understand the argument structure and metaethical commitments of Kant's foundational moral theory. It will also be of interest to anyone who wonders what we, as human beings, can legitimately expect from moral philosophy, and indeed philosophy in general ... . Ware's overarching picture of Kant's justificatory ambitions and strategies is informative and compelling.
