- 6. A paradox as a premise Plato Meno, XIV 80d–e/81a And how will you enquire, Socrates, into that which you do not know? What will you put forth as the subject of enquiry? And if you find what you want, how will you ever know that this is the thing which you did not know? I know, Meno, what you mean; but just see what a tiresome dispute you are introducing. You argue that man cannot enquire either about that which he knows, or about that which he does not know; for if he knows, he has no need to enquire; and if not, he cannot; for he does not know the very subject about which he is to enquire.
- 7. Anamnesys: a myth as an answer Plato Meno, XIV 81c-d “ Seeing then that the soul is immortal and has been born many times, and has beheld all things both in this world and in the nether realms, she has acquired knowledge of all and everything; so that it is no wonder that she should be able to recollect all that she knew before about virtue and other things. For as all nature is akin, and the soul has “ learned all things, there is no reason why we should not, by remembering but one single thing—an act which men call learning—discover everything else, if we have courage and faint not in the search; since, it would seem, research and learning are wholly recollection.
