History of Philosophy III: Kant and the 19th Century

The philosophical ideas and methods of Immanuel Kant's “critical” philosophy set off a revolution that reverberated through 19th-century philosophy.  We will trace the effects of this revolution and the responses to it, focusing specifically on the influence of Kant’s contribution to moral philosophy and its lasting influence on discussions of ethics and political philosophy.  We will begin with a consideration of Kant's famous Groundwork of the Metaphysics of Morals, in which he announces his project of grounding all ethical obligation in the very idea of a free will.  We will then consider Hegel's radicalization of this project in his Philosophy of Right, which seeks to derive from the idea of freedom, not just formal constraints on right action, but a determinate, positive conception of what Hegel calls "ethical life".  We will conclude with an examination of some important challenges to the Kantian/Hegelian project in ethical and political theory: Karl Marx’s re-interpretation of the idea of freedom in the economic sphere; Mary Wollstonecraft and John Stuart Mill’s radicalizations of the ideas of political liberty and equality; and the appropriation and critique of the Enlightenment rhetoric of freedom by writers on racial oppression including Frederick Douglass, W. E. B. DuBois, and Angela Davis.
