Jens Timmermann is Senior Lecturer in Moral Philosophy at the University of St Andrews. He is the author of Kant's 'Groundwork of the Metaphysics of Morals': A Commentary (Cambridge University Press, 2007) and of Kant's 'Groundwork of the Metaphysics of Morals': A Critical Guide (Cambridge University Press, 2010).

'It has taken more than two centuries, but at last we have a bilingual edition of the most important work in modern moral philosophy. On the left is the most authentic and accurate edition of Kant's original text currently available; on the right is a respectfully revised version of Mary Gregor's canonical translation of the Groundwork that makes her fine work even more precise. This is by far the best edition of the Groundwork for English-speaking students and scholars that has ever been produced.' Paul Guyer, University of Pennsylvania
