Wisdom is knowing when you can’t be wise.

The line frames wisdom as a form of self-knowledge and restraint rather than constant certainty. To “know when you can’t be wise” suggests recognizing moments when judgment is compromised—by emotion, limited information, fatigue, bias, or the sheer complexity of a situation. In those moments, the wisest act may be to pause, seek counsel, defer a decision, or accept ambiguity instead of forcing a premature conclusion. The aphorism also implies humility: wisdom includes awareness of one’s limits and the discipline to avoid performative “wisdom” when conditions don’t allow it. In that sense, it aligns wisdom with prudence and intellectual honesty.
