"The least initial deviation from the truth is multiplied later a thousandfold"
About this Quote
A tiny lie is never just a tiny lie; it is an error with compound interest. Aristotle’s line has the hard, almost mathematical bite you expect from a thinker obsessed with first principles. “Initial deviation” is doing the heavy lifting: he’s not talking about dramatic fraud so much as the first careless bend away from what is real. Once that bend is built into your premises, everything downstream can be impeccably logical and still catastrophically wrong. The subtext is a warning to anyone intoxicated by cleverness: reasoning is only as honest as its starting point.
This lands in a culture where “truth” isn’t merely personal sincerity but a claim about how the world is structured. Aristotle’s project in logic, ethics, and natural philosophy depends on the idea that knowledge is cumulative: we build from axioms, observations, definitions. If those foundations are slightly off, the system doesn’t wobble; it confidently marches in the wrong direction. The thousandfold multiplier is rhetorical exaggeration with a philosopher’s purpose: it dramatizes how small distortions become institutional realities - in courts, in politics, in science, even in self-justification.
There’s also a moral edge. Aristotle isn’t just policing accuracy; he’s policing character. The person who allows the “least” deviation trains themselves to prefer convenience over clarity. Over time, the psyche adapts: the lie becomes a lens. By the end, you’re not merely mistaken - you’re living in a world your own first compromise helped manufacture.
