Friedrich Nietzsche vs Immanuel Kant on Mind

Kant treats the mind as the source of the categories that structure any possible experience, with autonomy as its highest practical achievement. Nietzsche reads the same apparatus genealogically: what Kant identifies as the structure of pure reason is for Nietzsche a particular historical formation of the European mind, and the autonomous moral subject is the secularized inheritor of the Christian soul.

About this topic

Philosophy of mind asks what mental states are, how they relate to bodies and brains, and how thought, perception, and feeling are possible at all. Classical sources from Plato through Descartes treated the mind as a distinct substance, while later philosophers proposed varieties of materialism, functionalism, and emergentism in its place. Phenomenologists in the twentieth century turned attention to consciousness as it is lived from the inside. Contemporary philosophy of mind works in close dialogue with cognitive science.
