 The authenticity of this dialogue has been questioned (see  Section 17).  A dialogue of definition, the Hippias Major takes up the subject of the fine or beautiful (to kalon), one of the two most general terms of commendation in ancient Greek, the other being agathon, good, nearly a synonym. Being kalon is the primary feature of each of the virtues, and, by implication, the dialogue points to an important Socratic idea about ethics: That in being kalon a virtue is beneficial.
