SOCRATES: You mean that opinion admits of truth and falsehood, and hence becomes not merely opinion, but opinion of a certain quality; and this is what you think should be examined?
PROTARCHUS: Yes.
SOCRATES: And further, even if we admit the existence of qualities in other objects, may not pleasure and pain be simple and devoid of quality?
PROTARCHUS: Clearly.
SOCRATES: But there is no difficulty in seeing that pleasure and pain as well as opinion have qualities, for they are great or small, and have various degrees of intensity; as was indeed said long ago by us.
PROTARCHUS: Quite true.
SOCRATES: And if badness attaches to any of them, Protarchus, then we should speak of a bad opinion or of a bad pleasure?
PROTARCHUS: Quite true, Socrates.
SOCRATES: And if rightness attaches to any of them, should we not speak of a right opinion or right pleasure; and in like manner of the reverse of rightness?
PROTARCHUS: Certainly.
