Socrates himself wrote nothing. The line comes to us through Plato's Apology, where Socrates, on trial for his life in 399 BC, explains to the Athenian jury why the Oracle at Delphi had called him the wisest man in Greece. His own wisdom, he says, amounts only to this: he knows the size of his ignorance. Everyone else is walking around certain of things they have never examined. He was executed anyway.

The quote is beloved by people who have memorized it and use it strategically. That is a kind of betrayal of the sentence. Socrates was not striking a humble pose. He was describing a method. Start with an honest inventory of what you actually know as opposed to what you have heard, assumed, or inherited. The list will be short. The humility is not performative. It is arithmetic.

A cat wearing a pair of reading glasses perched on its nose is a visual joke about precisely this. The glasses suggest expertise. The cat has no use for them. It is taking the pose of a reader without the content. Most of our online certainty works the same way: the glasses without the reading. Socrates, who spent his last afternoon politely dismantling everyone else's confidence, would have appreciated the costume.
