1. See 276e, in Section C, where the sophists come close to the claim that they ‘muzzle’ people. Socrates’ meaning is probably that in arguments like that of Section C, which exploit linguistic ambiguities, the sophists effectively eradicate meaningful distinctions (see Rankin, p. 23).

2. See Section H.

3. Punctuating άνθρώπων, έγνων with Méridier. As usual, the contrast is with the lifelong Socratic search for virtue. See Sections M and N for Ctesippus imitating the sophists.

4. Pindar, Olympian 1.1.

5. Punctuating ούδέν μή ού with Hawtrey. Socrates is referring to the traditional division between concern with philosophy and concern with worldly affairs: each was commonly thought to be a full-time occupation.
