Die Metaphysik der Sitten.

The structure of the book feels very deliberate, but I'm curious about what guided Kant's choices in emphasizing duty over consequences or virtue.

The categories of duties felt complex but essential. I wonder if there's an intuitive way to understand their differences or if it's just a matter of careful study.

The integration of abstract metaphysical ideas with practical ethics feels both ambitious and groundbreaking. I'm curious about what motivated this approach.
