A man is known by the company he keeps

“A man is known by the company he keeps” is a proverb about character inferred from association. Its illustrative fable makes that judgment practical: a prospective buyer tests an Ass not by prolonged examination but by observing which of the other Asses it chooses to join. The episode’s pointed conclusion turns companionship into evidence and links a brief animal story to the collection’s moral teaching.

The Ass’s Trial

A Man arranges with the Ass’s owner to take the animal home and try it before buying. In the straw-yard, the newcomer leaves the other Asses and promptly joins the one described as the laziest and greatest eater. The buyer treats this immediate preference as decisive evidence: rather than extend the trial, he puts a halter on the Ass and leads him back to his owner.

Asked how he could have evaluated the animal in so little time, the Man explains that the Ass will be just like the companion he chose. The test therefore depends on a visible act of affiliation, not on an account of the Ass’s past or a lengthy assessment of his behavior. The decision to return him follows directly from that inference.

What Companionship Reveals

The proverb generalizes the buyer’s reasoning from the Ass to people: company is presented as a clue to the character of the person who chooses it. The fable’s force lies in the speed of the choice and the certainty with which the Man reads it. The Ass’s preference for the idle, greedy animal supplies the concrete circumstance behind the broader rule, while the buyer’s response shows that association can affect judgment before a relationship has had time to develop further.

The lesson is an inference the fable invites, not a claim that every association proves a person’s character in every circumstance. Here the story makes the connection especially clear by offering one conspicuous choice and an immediate consequence: the Ass selects his companion, and the buyer declines to purchase him.

Fable Form and Moral Instruction

The collection’s preface describes a fable as a short narrative that conveys an underlying lesson through fictitious characters. It argues that narration and moral should be closely joined, so that the instruction follows naturally from the action rather than arriving as an unrelated reflection. This episode follows that model: the Ass’s choice is the whole test, and the proverb gives that choice its general application.

The preface also notes that fables use animals to represent human motives while retaining recognizable animal characters. In the Ass and His Purchaser, the animal’s companionship makes the lesson legible through a simple action, and the concluding maxim carries that observation from the straw-yard into human society. The preface cautions, however, that not every story in the collection achieves equal unity between narrative and moral; its account of the form clarifies the standard this tightly linked example illustrates.
