Kantian Commitments comprises ten essays that represent a series of efforts to rethink many of the fundamentals of Kant's ethics and to draw out some implications for moral theory and practice. The essays of Part One revisit and revise central pieces of Kant's moral framework, offering a new understanding of the formulas of the categorical imperative, revisiting the idea of exceptions to duties, and sharpening the contrast between the value commitments of Kantian theory and other deontologies (especially recent contractualisms). The working hypothesis is to take seriously the idea that the formulas of the categorical imperative frame an account of moral reasoning with standards of validity and soundness that enable moral judgment to explicate the connection between our rational natures and our duties.

Part Two takes on some less central but important topics which are informed by the arguments of Part One: the rationale for Kant's moralized view of history; the implications of a Kantian view of morality for social pluralism; the fit of Kant's conception of moral psychology with affect-centered theories of human development; the motivation behind Kant's argument for indirect duties to animals; and the place of the idea of the highest good in a morally good life. The overall aim of the essays is to explore core Kantian commitments through a program of inquiry that peels away assumptions often brought to Kant's texts that introduce questions their arguments were not meant to answer. Removing these obstacles clarifies the ambition and scale of Kantian theory.
