“Know thyself”

“Know thyself” is Don Quixote’s central counsel to Sancho Panza as he prepares to govern. The maxim makes self-knowledge a practical safeguard: it should restrain pride, keep a person mindful of his origins, and shape how he exercises authority.

Counsel Before Office

Don Quixote presents self-knowledge as the second of his instructions to Sancho, after first urging him to fear God. He calls knowing oneself “the most difficult thing to know that the mind can imagine,” giving the short maxim weight as both a moral discipline and a demanding task. In the setting of an impending governorship, reflection is not abstract: offices and great trusts, he warns, are a gulf of troubles, and a governor needs guidance to navigate them.

Humility and Social Rank

To show what self-knowledge can prevent, Don Quixote invokes the frog that tried to make itself as large as an ox. He then points to Sancho’s former work keeping pigs as a reminder against puffing himself up. Sancho corrects the detail: he kept geese when he was older, and argues that a governor need not come from royal stock. Don Quixote accepts the point, but draws a related lesson: those without noble origins should meet the dignity of office with gentle suavity, which can protect them from the mockery no station escapes. The exchange turns the maxim from a warning about vanity into counsel about governing with humility, without treating humble birth as disqualification.
