SOCRATES: Reflect; would you not want wisdom and intelligence and forethought, and similar qualities? would you not at any rate want sight?
PROTARCHUS: Why should I? Having pleasure I should have all things.
SOCRATES: Living thus, you would always throughout your life enjoy the greatest pleasures?
PROTARCHUS: I should.
SOCRATES: But if you had neither mind, nor memory, nor knowledge, nor true opinion, you would in the first place be utterly ignorant of whether you were pleased or not, because you would be entirely devoid of intelligence.
PROTARCHUS: Certainly.
SOCRATES: And similarly, if you had no memory you would not recollect that you had ever been pleased, nor would the slightest recollection of the pleasure which you feel at any moment remain with you; and if you had no true opinion you would not think that you were pleased when you were; and if you had no power of calculation you would not be able to calculate on future pleasure, and your life would be the life, not of a man, but of an oyster or 'pulmo marinus.' Could this be otherwise?
PROTARCHUS: No.
SOCRATES: But is such a life eligible?
PROTARCHUS: I cannot answer you, Socrates; the argument has taken away from me the power of speech.
