Life's Pleasures Quote by Lucretius

"What is food to one man is bitter poison to others"

About this Quote

Dietary relativism, delivered with the chill certainty of physics. Lucretius isn’t offering a quaint proverb about picky eaters; he’s smuggling Epicurean philosophy into the pantry. In De Rerum Natura, the world is made of atoms and void, not divine preferences. So pleasure and pain aren’t moral verdicts handed down from Olympus; they’re effects, contingent on bodies, histories, and circumstance. What nourishes one person can injure another because nature has no single script for “good.” It has interactions.

The line works because it uses the most basic, intimate arena - eating - to pry open a much larger argument: stop treating your own sensations as universal law. “Food” reads as more than diet: customs, pleasures, ambitions, even ideologies. The subtext is quietly anti-authoritarian. If bitterness and sweetness vary by constitution, then the loudest preacher in the room is just broadcasting his own nervous system. That’s a direct hit on superstition and moral panic, both of which depend on pretending there’s one correct way to feel.

There’s also a bracing ethical implication: tolerance isn’t a sentimental virtue here, it’s a factual recognition of difference. Lucretius makes empathy sound like material science. He lets a simple sensory reversal expose how fragile our certainties are, and how quickly “truth” becomes a projection when we forget that bodies - and minds - aren’t standardized.

Evidence:
That what is food to one to some becomes Fierce poison, as a certain snake there is (Book IV, lines 636–637 (approx.; often cited as 4.636–637)). This is a modern English translation (William Ellery Leonard) of Lucretius’ Latin poem De Rerum Natura, Book IV. The underlying Latin commonly cited for the proverb is: “tantaque in his rebus distantia differitasque est, / ut quod aliis cibus est aliis fuat acre venenum;” (Book IV.636–637). The short, aphoristic form “What is food to one man is bitter poison to others” is a paraphrase/condensation of this passage, not a standalone line in Lucretius. The work itself was composed in the 1st century BCE (commonly placed in the mid–1st century BCE; Lucretius died 55 BCE). The earliest *publication* in the modern sense is much later because the poem circulated as manuscripts; the first printed edition is generally dated 1473 (incunable).
