“The ends justify the means” is the proverb at the heart of one of morality’s oldest debates. Here is what it means, where it comes from, how to use it, and a few sayings that share — or challenge — its logic.
What Does “The Ends Justify the Means” Mean?
The proverb means that a good or important final outcome can excuse the questionable, harmful, or immoral methods used to achieve it. If the goal is worthy enough, the argument goes, then whatever it takes to reach it is acceptable. It is most often used critically — as a warning about the dangers of this kind of thinking — because it can be used to justify almost any wrongdoing in the name of a “greater good.” Whether the ends ever truly justify the means is a question philosophers have debated for centuries.
Origin of the Proverb
The thought is ancient. The Roman poet Ovid wrote “exitus acta probat” — “the outcome justifies the deeds” — in his Heroides around 10 BC. The idea is most famously associated with Niccolò Machiavelli’s The Prince (1532), though Machiavelli never used the exact phrase; he argued, more subtly, that a ruler is judged by results when no higher authority can be appealed to. Over time, the blunt modern catchphrase came to stand for that whole Machiavellian way of thinking.
Examples in a Sentence
- “He cheated to win the contract, telling himself the ends justify the means.”
