The dialogue is normally separated into two sections. In the first half, Socrates and a companion attempt to seek a definition of "law," while in the second half Socrates praises Minos, the mythical king of Crete.
Definition of law
The dialogue opens with Socrates asking his nameless companion, "What is law for us?" The companion asks from Socrates to clarify which law he means exactly to which Socrates, somewhat surprised, asks from him whether the law is one or many. More specifically, Socrates asks his companion whether different laws are like parts of gold, with each part being from the same essence as the other, or like stones, with each being separate. The companion's answer is that law is nomizomena (νομιζόμενα) or "the things that are accepted by custom". The Greek word for law is nomos, which is also used to describe an established custom or practice. The companion defines nomos as something nomizomenon (the present passive participle of the related verb nomizō), meaning "accepted." Nomizō is used to mean "practice," "have in common or customary use," "enact," "treat," "consider as" and "belief," amongst other things. Socrates opposes this definition:
**Companion**: What else would law (*nomos*) be, Socrates, but the things that are accepted (*nomizomena*)? **Socrates**: And so speech, in your view, is the things that are said, or sight the things that are seen, or hearing the things that are heard? Or is speech one thing, the things that are spoken another, sight one thing, the things that are seen another, hearing one thing, and the things that are heard another—and so law one thing, the things that are accepted another? Is that so, or what is your view? **Companion**: They are two different things, as it now seems to me. **Socrates**: Law, then, is not the things that are accepted **Companion**: I think not.
Just like what we call "hearing" is not the sum of things heard but a sensation, a proper definition of law needs to capture an essence apart from the customary opinions that embody the law at any given moment. Supposing that laws are resolutions of a city, Socrates argues back saying that if we should consider law and justice to always be kaliston (κάλλιστον), "something most noble", while agreeing that a city's resolution can be either "admirable" or "wicked," it follows that identifying the law with these resolutions is incorrect. Instead, Socrates proceeds by asking what is good opinion.
**Socrates**: But what is a good opinion? Is it not a true opinion? **Companion**: Yes. **Socrates**: Now isn't true opinion, discovery of reality? **Companion**: It is. **Socrates**: Then ideally law is discovery of reality.
Socrates goes on to defend his definition of law as "that which wants to discover reality". His companion objects that if that was true then law would be same everywhere, but we know that it isn't, and he gives the example of human sacrifice which is forbidden in Crete where the dialogue takes place, while the Carthaginians and some Greek cities will practice it. Socrates proceeds to counter this argument using his famous method, asking from his companion to give short answers like he did in the Protagoras dialogue. He shows that since law is based on knowing reality, it cannot be different even if it appears to be. Just like the farmer is best at knowing the realities of the land, and the trainer of the human body, so is a king best in knowing the realities of human soul upon which laws should take effect. This is how the dialogue segues into praising Minos, the best, according to Socrates, of kings that have existed.
Praise of Minos
The dialogue eventually proceeds into praise of Minos, the mythical leader of Crete and an ancient enemy of Athens. Socrates counters his companion's opinion that Minos was unjust, saying that his idea is based on theater plays, but once they consult Homer and Hesiod, who are superior to all tragic playwrights put together, they shall find that Minos is worthy of praise. He continues by saying that Minos was the only man to be educated by Zeus himself, and created admirable laws for the Cretans, who are unique in avoiding excessive drinking, later teaching their practice to the Spartans. Minos instructed Rhadamanthus in parts of his "kingly art", enough for him to guard his laws. Zeus then gave Minos a man called Talos, that while thought to have been a giant robot-like automaton made of bronze, Socrates insists that his nickname of "brazen" was due to him holding bronze tablets where Minos' laws were inscribed.
After this encomium, Socrates' companion asks how is it, if everything that he had just heard was true, that Minos has such a bad reputation in Athens. Socrates responds by saying that this was the result of Minos attacking Athens while the city had good poets who, through their art, can harm a person greatly.
