Epicureanism = philosophy + practice + education
Epicureanism was much more than just another set of thought patterns to chat about the world.: besides the theoretical general world view (“Physics”), epistemology (“Canon”) and ethics it encompassed the daily communal practice of its tenets. The community members went through and education process to learn how to act and speak honestly and in harmony with their teachings (“parrhesia”), how to control their desires, how to manage their self-sufficient communities. For 800 years.
The philosophy of Marx and Engels, on the other hand, as interpreted and implemented by Lenin and his followers substituted the greed for money with the greed for power and served as “philosophical and scientific” foundation for the most oppressive and hypocritical communist regimes of almost half of the world for more than half a century.
