Euthyphro

Plato's dialogue Euthyphro illustrates Socrates' method of questioning to reveal that people lack clear definitions of concepts they use, such as piety.

THE IDEA

EUTHYPHRO

Plato expressed himself chiefly through his use of the person who no doubt became the most influential philosopher in history, Socrates the Athenian, the first philosopher in the modern sense. Socrates left no writing of his own, so we get direct representation of him mainly through Plato and Xenophon. And just as Fat Tony has, as his self-appointed biographer, yours truly trying to satisfy his own agenda, leading to distortions in his character and self-serving representation of some of the said author’s ideas, so I am certain that the Socrates of Plato is a more Platonic character than the true Socrates.1

In one of Plato’s dialogues, Euthyphro, Socrates was outside the courthouse, awaiting the trial in which he was eventually put to death, when the eponymous Euthyphro, a religious expert and prophet of sorts, struck up a conversation with him. Socrates started explaining that for the “activities” with which he was charged by the court (corrupting the youth and introducing new gods at the expense of the older ones), not only he did not charge a fee, but he was in perfect readiness to pay for people to listen to him.

It turned out that Euthyphro was on his way to charge his father with manslaughter, not a bad conversation starter. So Socrates started out by wondering how charging his own father with manslaughter was compatible with Euthyphro’s religious duties.

Socrates’ technique was to make his interlocutor, who started with a thesis, agree to a series of statements, then proceed to show him how the statements he agreed to are inconsistent with the original thesis, thus establishing that he has no clue as to what he was talking about. Socrates used it mostly to show people how lacking in clarity they were in their thoughts, how little they knew about the concepts they used routinely—and the need for philosophy to elucidate these concepts.

In the beginning of the Euthyphro dialogue, he catches his interlocutor using the word “piety,” characterizing the prosecution of his father as a pious act and so giving the impression that he was conducting the prosecution on grounds of piety. But he could not come up with a definition that suited Socrates. Socrates kept pestering the poor fellow as he could not produce a definition of piety. The dialogue continued with more definitions (what is “moral rectitude”?), until Euthyphro found some polite excuse to run away. The dialogue ended abruptly, but the reader is left with the impression that it could have gone on until today, twenty-five centuries later, without it bringing us any closer to anything.

When to use it

  • When debating, ask for definitions to uncover assumptions.

  • In education, use Socratic questioning to help students clarify their thinking.

  • In business, use it to challenge common wisdom or strategic assumptions.

  • In personal growth, examine your own ethical principles by attempting to define them.

FROM THEORY TO EVERYDAY LIFE

In practice

01

Socrates' questioning of Euthyphro

In Plato's dialogue, Socrates meets Euthyphro outside court and asks him to define piety. Despite claiming pious actions, Euthyphro cannot provide a consistent definition, revealing his ignorance.

✳

A MOMENT TO REFLECT

Put it to work.

  1. Can you define a term you use frequently? How would you respond to Socratic questioning?

  2. Think of a time you confidently used a concept but couldn't define it—what does that reveal?

  3. How can the Socratic method be applied to challenge your own beliefs?
