Mystères d'Éleusis
Along with Feuerbach, they also received inspiration from Richard Avenarius' "Naturfilisof", Ernst Mach's Empirio-criticism, as well as from Friedrich Nietzsche. Lunacharsky was also particularly interested in the Greek Mystery Schools, especially the Eleusinian Mysteries. Lunacharsky viewed the Eleusinian Mysteries as a model for how communal ritual could be used as a vehicle for the teaching of moral concepts.
