 When Socrates asks a question such as “What is reverence?” he has in mind a question that can be answered only in certain ways. To begin with, he will not be satisfied with an answer that points only to a certain kind of reverence, or only to an example of reverence. The answer must identify a feature that (1) belongs to every kind of reverence (generality requirement), and (2) belongs to nothing that is not reverent (exclusion requirement), and (3) has explanatory power—that is, explains why reverent people or actions are reverent.
