Aging & Wisdom Quote by Oliver Wendell Holmes Jr.

Holmes’s line lands like a judicial gavel wrapped in a punchline: the “secret of my success” isn’t genius or ambition, but the radical discipline of knowing you’re fallible. The phrasing matters. He addresses a “young man,” which frames the remark as a corrective to a familiar American temptation - early confidence curdling into certainty. Holmes is performing a kind of moral judo: he takes the cultural script of self-made greatness and flips it into an ethic of restraint.

The subtext is legal. A jurist who helped shape modern American jurisprudence, Holmes spent a career insisting that courts are not omniscient referees of truth or virtue. “I was not God” is a compact warning against judicial messianism - the idea that a judge can legislate morality from the bench, or treat personal convictions as constitutional law. It’s also an institutional defense of democracy: if no one is God, then no single mind (especially one wearing a robe) gets final, cosmic authority over a plural society.

Context sharpens the bite. Holmes lived through the Civil War, industrial upheaval, and the rise of mass politics. He watched certainty justify slaughter, and later watched certainty justify repression. So the joke carries scars. It’s humility, yes, but not the soft, self-help kind. It’s the hard humility that makes room for disagreement, experimentation, and error - the humility that lets a system survive contact with human beings.
