Epicurus was an ancient Greek philosopher who founded the philosophy of Epicureanism. He believed that pleasure is the highest good and that death should not be feared. Epicurean ethics are based on hedonism and seeking to avoid pain. Epicurus emphasized finding calm pleasures of the soul rather than intense physical pleasures. He believed that by limiting desires to only natural and necessary ones, one could achieve ataraxia and aponia, the highest forms of happiness and freedom from pain. Justice was seen as a social contract to avoid harming others so that people are free to pursue pleasure.
