Michelle Kosch examines the conceptions of free will and the foundations of ethics in the work of Kant, Schelling, and Kierkegaard. She seeks to understand the history of German idealism better by looking at it through the lens of these issues, and to understand Kierkegaard better by placing his thought in this context. Kosch argues for a new interpretation of Kierkegaard's theory of agency, that Schelling was a major influence and Kant a major target of criticism, and that both the theory and the criticisms are highly relevant to contemporary debates.
