On the Nature of Things for Seekers

Dear reader — a Roman poet in the 50s BCE took the whole philosophy of Epicurus, atoms, empty space, a soul that dies with the body, gods who don't interfere, and wrote it as a six-book poem. De Rerum Natura, usually translated On the Nature of Things. Why verse? He tells you. It's a dry philosophy in sweet words, the way doctors smear honey on the rim of a cup of bitter medicine so the kids will drink it. I'd call it the oldest trick in the book, except it's literally one of the oldest books.

What We Know About The Guy (Not Much)

Almost nothing. Probably born around 99 BCE, died around 55 BCE, writing at the end of the Roman Republic during the civil wars that eventually brought it down. A later story from Saint Jerome says he was driven mad by a love potion. That's a story told centuries after, by a Christian, about a poet who denied the afterlife, so I'd hold it loosely.

The philosophy is Epicurus's. He lived in Athens from 341 to 270 BCE and taught in a garden outside the city. His claim: the aim of life is pleasure, meaning freedom from pain and disturbance of mind, not indulgence. To get there you remove the big sources of fear, mainly the gods and death. Lucretius treats Epicurus almost like a savior. He's the "Greek" of Book I, the man who "first uplifted in such dark / So clear a torch aloft."

Books I And II: Atoms, Void, And Religion Under Foot

The poem opens with a prayer to Venus, the mother of the Roman people, as the power of generation and joy. Readers find that paradoxical, an Epicurean poem starting by praising a goddess. Possible readings: she's a symbol of nature's creative force, or Lucretius is working inside Roman convention. The guide leaves it open and so will I.

Then his boldest claim. For ages human life lay crushed under Religion, who looked down from the sky with a hideous face, until a Greek dared lift his eyes against her. To show religion breeds crime, not philosophy, he tells the story of Iphigenia, sacrificed by her father Agamemnon at Aulis to win good winds for the Greek fleet. He lingers on the girl, her silent terror, the priests with the knife, the bridal hymn that is not sung. His verdict: "Such are the crimes to which Religion leads."

Then the physics. First argument: "Nothing from nothing ever yet was born." If anything could come from anything, men might rise from the sea and crops grow in any season. But each thing comes from its own kind of seed, at the proper time.

My favorite analogy: the alphabet. A small number of letters, arranged differently, make an endless variety of words. A limited number of kinds of atoms, combining in different patterns, make all the different things in the world.

Book II opens with one of the best-known passages: it's sweet, he says, to watch from the land while the winds stir the sea and another man struggles in it. He's careful to say this isn't because we enjoy his misery, it's because we enjoy seeing what we're free of. And the line that's a refrain through the whole poem: "For just as children tremble and fear all / In the viewless dark, so even we at times / Dread in the light so many things that be / No whit..." The terror isn't cured by sunrise but by understanding nature.

Then the swerve. If atoms only fell straight down through empty space, they'd never collide and nothing would ever be created. So, he proposes, they swerve a little, at no fixed time or place: "The atoms must a little swerve at times — / But only the least." That tiny deviation breaks the chain of cause and effect, starts collisions, and makes room for freedom. And everything changes: the world, like every compound thing, is made of atoms, so it must someday dissolve. The earth, once young and fertile, now ages like a woman past childbearing.

Book III: Death Is Nothing To Us

The heart of the poem and its most quoted part. It opens with a praise of Epicurus, whom Lucretius follows not like a rival but out of love, as a swallow can't compete with swans. When he thinks of the master's teaching, the terrors of the mind flee.

The central argument comes after a long proof that the soul, made of fine atoms, dissolves at death. If the soul dies with the body there's no one left to suffer. "Therefore death to us / Is nothing, nor concerns us in the least, / Since nature of mind is mortal evermore." Being dead will be like the time before we were born, which we don't regret.

His second picture of the same idea is a mirror. Look back across all the ages before you were born. "Nothing to us was all fore-passed eld / Of time the eternal, ere we had a birth. / And Nature holds this like a mirror up" to the time after our death. Is that so horrible?

Then he takes the underworld apart. No real torments after death, he says. The myths are pictures of torments in this life. Tantalus, afraid of a rock hanging over him, stands for people who live in empty dread of the gods. Sisyphus, rolling his stone, is the politician who seeks office again and again and is beaten back.

And the Restless Man. Someone's sick of home, leaves his grand house, drives off to his country villa like he's putting out a fire, yawns at the doorstep, and comes back. "Each human flees himself — a self in sooth, / As happens, he by no means can escape." If we could see the cause of that unease, we'd drop everything and study nature instead.

Books IV To VI: The World And Its People

Book IV begins with how images from things reach our eyes and minds, which explains vision, dreams, and illusion. It ends with a harsh analysis of sexual desire, treating passion as a sickness that feeds on illusion. I'll flag that and move on. It's the least comfortable stretch in the poem and he knew it.

Book V is the natural history of everything. How life began: in a young world the earth herself produced creatures, wombs rising from the ground, and the fields gave milk. Which is why we call her Mother Earth. But the early earth also produced monsters, beings without feet or hands, and those didn't last.

And a natural history of religion. People saw dreams of powerful beings, saw night and day, the moon and stars, storms and lightning, and assumed gods did it, and set their homes in the sky because that's where the great motions were. That, he says, made people miserable. True piety, he says, isn't being seen with your head veiled, turning toward a stone, approaching every altar, or falling flat with your palms up. It's to "look on all things with a master eye and a mind at peace."

The last book explains thunder, volcanoes, earthquakes, magnets, and disease, and ends with a long description of the plague at Athens in 430 BCE, adapted from Thucydides. One of the most harrowing passages in Latin poetry. Corpses, despair, the breakdown of everything. It's a strange place to stop a poem about peace of mind, and that's the point you have to decide about yourself.

The Simple Life

Nature asks little: no pain in the body and a mind free of fear. A picnic by a stream under a tall tree, with friends, on a fine spring day, beats a house full of gold and silver. Wealth and rank don't cure a fever, and a purple robe is no better than a poor man's bedding.

Change and return is the consolation. Everything comes apart and returns. Nothing's annihilated, nothing created from nothing. Individual things die but the matter that composed them gets used again. We're part of a cycle that continues.

How It Almost Got Lost

In the Middle Ages the poem nearly vanished. Christian readers distrusted its denial of the afterlife and divine providence, and few copies were made. In 1417 the Italian humanist Poggio Bracciolini found a copy in a German monastery and had it transcribed, and it spread fast through Renaissance Italy.

Modern readers are struck by how much seems prescient: matter made of atoms, conservation of matter, a sort of natural selection, the natural history of religion. Others warn against reading it as early modern science. It has no experiments, it runs on analogy and argument. Some read it as a consolation, a clear gentle way to face death. Others as a challenge, a demand to give up the comfort of an afterlife and a world governed by purpose. Both kinds of readers keep coming back.

If you're going to read it: the translation quoted here is William Ellery Leonard's 1916 blank verse, public domain, readable, a bit dated, with a few marked gaps where the Latin is missing. It takes about six to eight hours, and you don't have to read it in order. Six books in three pairs: atoms and void, soul and sense, the world and its history. If time is short, read the proems, Book III's argument about death, and the plague at the end. The physics is the slowest part and can be skimmed.
