In Plato's Meno, it is talked about how knowledge is neither gained nor searched for. I am confused on this particular question. What does is entail?
It entails that acccording to Socrates - the Platonic Socrates - thinks there is another source knowledge. So, what is it ? ('Platonic Socrates' because here and elsewhere we can't be sure how far the views of the historical Socrates are represented.)
▻ MENO AND KNOWLEDGE
Because, as you put it, the view emerges in the Meno that knowledge can be neither gained nor searched for, it not follow that the possession of knowledge is impossible. Quite the opposite. In the dialogue Socrates elicits from a slave boy the right answers to certain geometrical questions : e.g that if the side of a square is two feet, the size of the figure is four square feet, and the questions delve into much further complications. The slave boy sometimes hesitates, sometimes gets things wrong, but without (it is claimed) any instruction from Socrates he is eventually able to prove Pythagoras' Theorem.
Then he has knowledge. He did not seek it. He did not gain it from Socrates (or supposedly so - it's an open question how much knowledge is implicitly imparted by Socrates' questioning). He gained it, so Socrates hypothesises (81a-82b), by recollection (anamnesis). If the boy has geometrical knowledge, he has not acquired it in his present life; he must be recollecting from a past existence.
Perhaps not the most cogent of Socrates hypotheses but there it is. I hope this eases your puzzlement.
