""An Introduction to the Metaphysics of Morals"" is a philosophical work by the renowned German philosopher Immanuel Kant. The book is a fundamental text on moral philosophy, providing an introduction to Kant's ethical system and his ideas on the nature of morality. Kant's central thesis is that moral principles are grounded in reason and are universal, necessary, and objective. The book is divided into three parts, with the first part discussing the concept of moral autonomy and the second part exploring the concept of duty. The final part of the book discusses the relationship between morality and religion. Throughout the book, Kant argues that moral principles are not based on subjective feelings or social conventions, but rather on the inherent nature of reason itself. This work is considered one of the most important and influential texts in the history of philosophy, and has had a profound impact on ethical theory and moral philosophy.The active faculty of the human mind, as the faculty of desire in its widest sense, is the power which man has, through his mental representations, of becoming the cause of objects corresponding to these representations. The capacity of a being to act in conformity with his own representations is what constitutes the life of such a being.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
