SOCRATES: Yes.
PROTARCHUS: Why then, Socrates, I should suppose that there would be neither pleasure nor pain.
SOCRATES: Very good; but still, if I am not mistaken, you do assert that we must always be experiencing one of them; that is what the wise tell us; for, say they, all things are ever flowing up and down.
PROTARCHUS: Yes, and their words are of no mean authority.
SOCRATES: Of course, for they are no mean authorities themselves; and I should like to avoid the brunt of their argument. Shall I tell you how I mean to escape from them? And you shall be the partner of my flight.
PROTARCHUS: How?
SOCRATES: To them we will say: 'Good; but are we, or living things in general, always conscious of what happens to us—for example, of our growth, or the like? Are we not, on the contrary, almost wholly unconscious of this and similar phenomena?' You must answer for them.
PROTARCHUS: The latter alternative is the true one.
SOCRATES: Then we were not right in saying, just now, that motions going up and down cause pleasures and pains?
PROTARCHUS: True.
