This book brings together eleven papers on Kantian ethics which Thomas Hill wrote between 1971 and 1989. Nine of the eleven deal quite directly with the exegesis of Kantian texts on moral philosophy or the critical exposition of parts of Kantian moral theory. The tenth attempts to apply Kantian theory to a particularly difficult moral problem of a kind it has often been thought Kantian ethics could not handle: how to deal with terrorism and to make the kinds of life and death decisions this sometimes involves. The final paper, and "Kantian Constructivism in Ethics, and " is about Rawls as much as Kant, and reflects on the affinities between Rawls's and "constructivist and " project in ethics and the Kantian roots of Rawls's theory.
