What are the Foundations of the Metaphysics of Morals and the Critique of Practical Reason about? On the foundation of moral discourse, of a coherent discourse, absolutely valid for all beings endowed with reason, binding on everything that is finite and reasonable. It is not a question of morality in the traditional sense of the term, of a system of rules of conduct for concrete situations, of precise prescriptions, of prohibitions to be observed. What Kant is looking for is exactly what the title of the first of these writings indicates: a foundation of the metaphysics of morals, not this one. Morals, history and the present are full of them, without any of the systems advocated being able to claim universal validity: morality remains to be founded.
