De La Philosophie Morale, ou Des Differens Systemes sur la Science de la Vie is an iconic work by Joseph Droz, a French philosopher who lived during the French Revolution. The book argues that society can only be in a proper state if individuals are educated to prioritize their duties over their rights. This doctrine earned Droz the Montyon Prize in 1823 and admission to the Académie française. The second edition of the book, published in 1924, is a hardcover volume with marbled boards and brown leather spine and edges. Despite some rubbing and wear to the corners, the book is in very good condition for its age, with little overall fading or yellowing to the pages.
