The wheels of justice is used to describe the legal system as a great, grinding machine that moves at its own pace, indifferent to the wishes of those caught up in it. It is almost always paired with a comment on speed, usually that the wheels turn slowly, and the phrase carries a double message: patience is required, but the outcome, when it comes, will be thorough and correct. People reach for it when a court case, an investigation, or an appeal drags on, as a way of acknowledging the frustration while insisting that the system will still get where it is going.
What’s the origin of the phrase ‘the wheels of justice’?
The image behind the phrase is far older than any legal system it now describes. The ancient Greeks had a proverb about the mills of the gods grinding out retribution, and it was already treated as a familiar saying by the first-century writer Plutarch, who wrote that he did not see the use of “those mills of the gods said to grind so late as to render punishment hard to be recognized.” The philosopher Sextus Empiricus recorded the same idea in Greek a century or two later. The Latin line usually quoted alongside it, “Est mola tarda dei, verum molit illa minutim”, roughly “the mill of god is slow, but it grinds fine”, comes from a later Latin rendering rather than from Sextus himself.
The now-familiar wording owes a great deal to the poet Longfellow, whose 1845 translation of a German epigram by Friedrich von Logau gave English the phrase “grind exceeding small”, a rendering that does not appear to have existed in quite that form before his version.
The switch from divine mills to legal wheels came later. The earliest known printed use of the image applied specifically to justice, rather than to God or the gods, dates from 1890, in a line asking “If the mills of the Gods grind slowly, what shall we say of the wheels of justice?” From there the two images gradually merged, and by 1920 the full modern form had settled into place: a published transcript of a Carnegie Hall debate that year records the line “the wheels of justice turn slowly, but grind exceedingly fine.” That combination of turning wheels and fine grinding is essentially the phrase still used today, and in current usage it has largely replaced the older “mills of justice” wording. It sits close in spirit to the idea of ‘poetic justice’, though that phrase is about fitting outcomes rather than slow ones.
