Epicurus's Principal Doctrines and his Letter to Menoeceus are presented in this excellent edition which includes multiple translations, the original Greek, plus supplementary essays on Epicureanism by respected scholars. In the 3rd century B.C. Epicurus became renowned for developing a system of moral and social philosophy which was popular during ancient times. Epicureanism underwent a resurgence among intellectuals, scholars and Christian believers during the Enlightenment era. A prodigious author during his lifetime, tragically most of the works Epicurus wrote are lost, with only a handful of texts remaining extant for study in the present day. Epicurus advocated a peaceful existence defined by modest living; cultivation of inner peace and fearlessness; surrounding oneself in personal tranquility with worthy friends and family members as good company; and the observation of justice.
