Marx sees Epicurus as a destroyer of the Greek myths and as a philosopher bringing to light the break-up of a tribal community. His system destroyed the visible heaven of the ancients as a keystone of political and religious life. Marx allies himself, so to speak, with Epicurean atheism, which he regards at this stage as a challenge by the intellectual élite to the cohorts of common sense. 'As long as a single drop of blood pulses in her world-conquering and totally free heart, philosophy will continually shout at her opponents the cry of Epicurus: Impiety does not consist in destroying the gods of the crowd but rather in ascribing to the gods the ideas of the crowd.
