Time & Perspective Quote by Oliver Wendell Holmes Jr.

Holmes turns mastery into a chase scene. Events don’t arrive politely, waiting for a competent mind to file them under “handled”; they surge forward, and the only way to command them is to leap while they’re moving. The image is physical, risky, almost undignified. That’s the point. It punctures the fantasy of control as something achieved from a chair, with time to deliberate until certainty crystallizes.

Coming from a jurist who helped shape modern American legal realism, the subtext is pointed: law is not a sealed container of timeless principles but a practice conducted inside history’s velocity. Judges, like everyone else, grab for meaning mid-stride. “Mounted on the run” suggests decision under pressure, when facts are incomplete and consequences are already unfolding. Holmes is slyly anti-romantic about the intellect, too. The mind doesn’t “possess” thoughts; it snatches them. Ideas are not treasures you store, but animals you either catch or miss.

The reins metaphor matters. A rider doesn’t stop the horse to contemplate horsemanship; control is negotiated with motion. Holmes implies that thinking is less about pristine logic than about timing, attention, and nerve. If you hesitate, the thought is gone and you’re left with a tidy explanation of why you couldn’t act.

In the wider context of Holmes’s era - industrial acceleration, political shocks, modern war’s lessons in contingency - this reads like a philosophy of pragmatism disguised as aphorism: adapt quickly, decide cleanly, and accept that mastery is always provisional, earned at speed.
