Epicurus (341-270 B.C.) was a Greek philosopher who claimed the cosmos was eternal and merely material, made up of atoms and void. Yet, breaking with his predecessor Democritus, he considered the universe indeterminate. In the realm of ethics, Epicurus taught that the purpose of human life was the pursuit of happiness, which could be achieved by the measured study of the natural world and adherence to a prudent and temperate hedonism.

He counseled men not to fear their own death, saying,

Foolish, therefore, is the man who says that he fears death, not because it will pain when it comes, but because it pains in the prospect. Whatever causes no annoyance when it is present, causes only a groundless pain in the expectation. Death, therefore, the most awful of evils, is nothing to us, seeing that, when we are, death is not come, and, when death is come, we are not.

He considered friendship as the utmost means of securing wisdom, saying,

Friendship dances around the world, bidding us all to awaken to the recognition of happiness…The same conviction which inspires confidence that nothing we have to fear is eternal or even of long duration, also enables us to see that in the limited evils of this life nothing enhances our security so much as friendship.”

He advised men to avoid vain ambitions such as the pursuit of fame, exorbitant wealth, and political power for their own sake. Rather, he thought wise men would be “strong and self-sufficient” and “take pride in their own personal qualities not in those that depend on external circumstances.”

To Epicurus, pain is a natural evil, pleasure a natural good, with the ultimate pleasure being the absence of bodily pain and tranquility of the mind. From his Letter to Menoeceus:

When we say, then, that pleasure is the end and aim, we do not mean the pleasures of the prodigal or the pleasures of sensuality, as we are understood to do by some through ignorance, prejudice, or willful misrepresentation. By pleasure we mean the absence of pain in the body and of trouble in the soul. It is not an unbroken succession of drinking-bouts and of revelry, not sexual lust, not the enjoyment of the fish and other delicacies of a luxurious table, which produce a pleasant life; it is sober reasoning, searching out the grounds of every choice and avoidance, and banishing those beliefs through which the greatest tumults take possession of the soul.

Nevertheless, because Epicurus claimed the ultimate aim of happiness is to find pleasure – and not virtue or knowledge unto themselves – many of his contemporaries and later critics would uncharitably accuse him of advocating debauchery, one even saying he “vomited twice a day from over-indulgence,” and that his understanding of philosophy and life in general was wanting.

One might hear the very same smear today from mainstream American partisans in regard to libertarians, i.e. that liberty lovers are simply “pot-smoking republicans” or libertines who barely understand life and are too drunk on utopian dreams to see clearly. In this same vein, many reproached Epicurus (as they do of libertarians today) for his aloof stance on politics as apathetic and his notion of justice as too transactional.

“Natural justice is a pledge of reciprocal benefit,” writes Epicurus in his Principal Doctrines, “to prevent one man from harming or being harmed by another.” Elsewhere he writes, “We must free ourselves from the prison of public education and politics.”

Accordingly, Epicurus set up his own school, “The Garden,” where he offered philosophy to anyone, even women and slaves – an unheard of practice at the time, which many contemporary critics saw as proof of his penchant for depraved behavior. Why else would one invite women and slaves into one’s abode other than revelry? Was he actually going to talk to them about ideas?

Thankfully, we have Diogenes Laërtius to defend Epicurus from his detractors:

But these people are stark mad. For our philosopher has numerous witnesses to attest his unsurpassed goodwill to all men – his native land, which honored him with statues in bronze; his friends, so many in number that they could hardly be counted by whole cities, and indeed all who knew him, held fast as they were by the siren-charms of his doctrine…the Garden itself which, while nearly all the others have died out, continues for ever without interruption through numberless successions of one director after another; his gratitude to his parents, his generosity to his brothers, his gentleness to his servants, as evidenced by the terms of his will and by the fact that they were members of the Garden…and in general, his benevolence to all mankind. His piety towards the gods and his affection for his country no words can describe. He carried his modesty to such an excess that he did not even enter public life.
