Tolerance for unresolved questions is a learnable skill — and for most people, it atrophies with age. The Scottish philosopher David Hume noticed something counterintuitive about how the mind handles uncertainty: the more familiar we become with a domain, the stronger the impulse to force its loose ends into tidy explanations. He called this 'the love of system' — the aesthetic pull toward closure that masquerades as rigor. But the Scottish polymath James Clerk Maxwell, who read Hume obsessively before developing his equations for electromagnetism, practiced something almost opposite: he kept a private notebook he called his 'waste book' where he would deliberately write down questions he couldn't yet answer, and return to them for years without resolution. The discipline wasn't patience — it was active, structured refusal to prematurely close. For Maxwell, an unresolved question wasn't a gap to fill; it was a live wire, kept deliberately live. The practice available to you is concrete: maintain a short list of questions you genuinely don't know the answer to — not tasks, not problems with known methods, but real open questions — and resist the reflex to convert them into answers too quickly.

What question have you been carrying lately that you've quietly converted into a premature answer — and what would it cost you to reopen it?
