Morelly (flourished 18th century) was a French philosopher whose writings influenced Communist doctrine. His works, which frequently delineate a utopian society based on Communist principles, include Essai sur l’esprit humain (1743; “Essay on the Human Spirit”), Essais sur le coeur humain ou principes naturels de l’éducation (1745; “Essays on the Human Heart, or Natural Principles of Education”), and Le Code de la nature (1755; “The Law of Nature”).
