The chapter examines Kant's treatment of lying, avarice, and servility or false humility in the "Doctrine of Virtue" (6:428–437). While those moral issues are traditionally construed as regarding moral demands towards others, Kant deals with them under the heading of the duty that a human being has toward himself merely as a moral being. The chapter analyzes Kant's arguments on each of those moral questions and concludes considering Kant's remarks on love of honour, or pride, as the corresponding virtue towards oneself as a moral being.

The chapter shows how Kant’s ethical thought as reflected in the lectures, responds to Baumgarten’s works on moral philosophy. I argue that Kant chose Baumgarten’s textbooks for his classes for genuinely philosophical reasons. The thorough discussion of Baumgarten’s views provided Kant with important clues for developing an original position, even if mostly in opposition to Baumgarten. I illustrate this complex role of Baumgarten with a few significant examples, that also highlight some original aspects of Baumgarten’s position in comparison to Wolff’s: (1) Kant follows Baumgarten’s in focusing on obligation as the crucial issue in moral philosophy, but Kant regards Baumgarten’s account as not satisfying. (2) Baumgarten’s sharply theistic foundation of morality is rejected by Kant. (3) Kant rejects also several significant aspects of Baumgarten’s division of ethical duties, thereby revealing profound differences in their conceptions of morality.

The book presents a reconstruction of the development of Kant’s ethical thought from the 1760s till the "Metaphysics of Morals" of 1797 with a focus on the evolution of Kant’s overall project in practical philosophy. The main steps in the development of his practical philosophy are interpreted as successive attempts to connect normative ethics with an innovative preliminary descriptive inquiry. The book reconstructs the different ways in which Kant focuses this plan, stressing both the unity and the breaks in Kant’s development. I thus distinguish three main phases, characterised by a different systematic project. The first part is devoted to Kant’s work on moral theory up to 1769. The second part examines Kant’s new ethical project from 1770 to 1785, while the third part considers the further developments from the second "Critique" to the "Metaphysics of Morals".

The chapter first discusses the general meaning of a 'doctrine of method' in Kant’s work, as well as the specific goals of the Doctrine of Method of the second Critique. The central section, then, focuses on the notion of 'receptivity to morality', which here has a central role and a quite distinct meaning. I argue that Kant’s main point in his account of how to 'make objective practical reason subjectively practical' (5:151) is that one ought to lead the individual agent to become aware of his own dignity as a moral being. In Kant’s view, recognition of this point is relevant to the overall aim of the second Critique – to show that pure reason is practical – and of moral theory itself. The task of the Doctrine of Method is to show how it is possible to make agents aware of their basic moral capacities, and through that awareness to instil genuine moral dispositions. Accordingly, the Doctrine of Method is the completion of the Critique, confirming the conclusions of the Analytic through the common use of pure practical reason and connecting them with the experience of every moral agent.
