The one in the many

What do all the cases of a thing share? A definition is first asked for as one account that holds in every case, not a list of examples. These readings ask what kind of answer meets that demand.

In Plato’s Euthyphro, Socrates, on his way to answer the indictment against him, asks Euthyphro what “piety” is and rejects a list of examples. He asks for “one idea” and for a “standard” to which he may “look”. The early dialogues of Plato are the source of the Socratic question “what is it?”, and this passage stands under the one in the many for the way the question is put.

In Plato’s Laches, Socrates and the two generals, Laches and Nicias, are asked whether boys should learn fighting in armour, and the inquiry turns to the question what “courage” is. Here Socrates explains the kind of answer he seeks by the example of “quickness”, a “common quality” found in many actions. The passage stands under the one in the many for his phrase “the same in all these cases”.

In Plato’s Meno, Socrates asks Meno what “figure” is, after Meno has answered the question what virtue is by listing the virtues of different persons. The Latin phrase simile in multis in the Jowett translation names what he is looking for. The dialogue sets the problem of definition before the problem of how virtue is taught, and it stands under the one in the many for that reason.

In Plato’s Theaetetus, early in the inquiry into what knowledge is, Socrates objects that Theaetetus has listed the sciences instead of saying what knowledge is, and takes “clay” as his example. The dialogue is Plato’s principal discussion of knowledge (episteme). The passage stands under the one in the many for the demand to know “the nature” of a thing before one can use its name.
