Metaphysical Elements of Ethics: A Systematic Account of Duty, Law, and Moral Reasoning

A foundational work of moral philosophy in which Kant sets out the principles of duty, law, and ethical reasoning within a systematic framework.

In The Metaphysical Elements of Ethics, Immanuel Kant develops a structured account of moral obligation grounded in reason rather than inclination. The work forms part of his broader critical philosophy and presents an examination of how ethical laws arise from rational principles that are universally binding. Kant distinguishes between actions performed from duty and those guided by contingent motives, arguing that moral worth resides in adherence to principles that can be consistently willed as universal laws.

The text is divided into sections addressing the doctrine of right and the doctrine of virtue, considering both external conduct and inward moral disposition. Kant's method is analytical and precise, seeking to establish ethics as a discipline governed by necessity and coherence rather than circumstance. First published in the late eighteenth century, the work remains central to the study of philosophy and continues to inform discussions of moral responsibility, autonomy, and the nature of ethical judgement.
