Fundamental Principles of the Metaphysic Of Morals

Kant's exploration of moral philosophy presents a foundational argument for an a priori basis of morality, building on concepts introduced in his earlier work. The treatise is structured into a preface and three sections, progressing from common reason to the identification of a supreme unconditional law, and then reinforcing the significance of moral law. The final section is notably complex, prompting Kant to later expand on these ideas in the "Critique of Practical Reason." This work serves as a crucial precursor to his later philosophical contributions.
