The Origin Of ‘Kill Two Birds With One Stone’

The origin of the phrase ‘kill two birds with one stone’ is unclear, however, one theory for how it might have originated is from hunting. Birds are killed during hunting, after all. Oftentimes a hunter uses a gun or a knife to accomplish this, but a blunt object like a stone could be effective too.

How would the hunter kill two birds with one stone? He could just sneak up on some unsuspecting birds and throw it at one of them, then pick it up and repeat. Simply enough. However, this phrase might also derive from an older, similar expression that goes “to stop two gaps with one bush.” This older expression appears in The Proverbs of John Heywood, 1546:

“I will learne to stop two gaps with one bush.”

A little more than a century later, the phrase “two birds, one stone” is seen in a work by Thomas Hobbes called The Questions Concerning Liberty, Necessity and Chance, 1656:

“T. H. thinks to kill two birds with one stone, and satisfie two Arguments with one answer, whereas in truth he satisfieth neither.”

Since the phrase dates back to 1656, it’s at least 360 years old.
