This volume presents a selection of Robert Stern’s work on the theme of Kantian ethics. It begins by focusing on the relation between Kant’s account of obligation and his view of autonomy, arguing that this leaves room for Kant to be a realist about value. Stern then considers where this places Kant in relation to the question of moral scepticism, and in relation to the principle of ‘ought implies can’, and examines this principle in its own right. The papers then move beyond Kant himself to his wider influence and to critics of his work, and the volume concludes with a consideration of a broadly Kantian critique of divine command ethics offered by Stephen Darwall. General themes considered in this volume include value, perfectionism, agency, autonomy, moral motivation, moral scepticism, and obligation, as well as the historical place of Kant’s ethics and its influence on thinkers up to the present day.
