History was not kind to the ancient Greek philosopher Epicurus: few of the thinkers were so misunderstood by descendants. For many centuries, epicureans have been called gluttons, hedonists, lovers of living for their own pleasure - and all because the philosopher considered pleasure to be the highest good in life. But what was the real pleasure for Epicurus, who called for contentment with little and showed his students the way to spiritual serenity? The book of the English philosopher John Sellars truthfully and simply talks about tetrapharmakos - an Epicurean teaching that heals from anxieties and fears and is based on atomistic theory.
