Does a name reveal what a thing is, or only what we agree to call it?
In Plato’s Cratylus, a quarrel about names opens a larger question about truth. Hermogenes says names rest on agreement. Cratylus insists that each thing has a name that fits it by nature. Between them stands Socrates, testing both claims with sharp questions, serious arguments, and playful turns that keep the discussion alive.
The debate moves through Greek words, the names of gods and heroes, and terms for justice, courage, and wisdom. Socrates considers the name-giver as a craftsman and asks whether sounds can imitate things. At stake is more than how we speak: can words guide us toward knowledge, or must we look beyond them?
What you’ll discover
- Two views in conflict Watch Hermogenes and Cratylus defend rival answers to a question hidden in everyday speech.

In short
Cratylus is a dialogue by Plato, the Athenian philosopher who died in 348 BC. It is usually placed among his middle works, though scholars cannot date it with certainty.
From the 15-minute summary · Key idea 1
Two rival theories about what names are
The dialogue opens with a quarrel already under way. Hermogenes tells Socrates that his friend Cratylus claims each thing has a name that belongs to it by nature. Cratylus even says that Hermogenes is not truly the name of this man at all. Hermogenes is puzzled and a little hurt, and he asks Socrates to judge.
Hermogenes himself holds the opposite view. For him a name is whatever people agree to call a thing. If you decide to call a horse a man and a man a horse, then the names simply change. He compares it to household slaves, who may be renamed by their masters at will. The Greek word for this idea is nomos, meaning custom or law, and the view is called conventionalism.

What is Plato's Cratylus about?
It is a dialogue about the correctness of names. Hermogenes says names come from agreement, Cratylus says they fit things by nature, and Socrates tests both views. It also touches on knowledge and the idea that all things flow.
Who are Hermogenes and Cratylus?
Hermogenes is a speaker who holds that names are set by convention. Cratylus is a follower of Heraclitean ideas who holds that names are right by nature. Socrates talks with both and questions their claims.
Are the etymologies in Cratylus meant to be serious?
Scholars disagree. Some read the word explanations as a joke at the expense of other thinkers. Others think Plato takes part of the method seriously. Modern linguists do not accept most of the explanations as true history of the words.
