The Paradox of Inquiry — How can we learn what we don't know?
MENO: And how will you search for something, Socrates, when you don't know at all what it is? What sort of thing will you put before yourself as the object of your search? Even if you happen to come across it, how will you know that this is the thing you didn't know?
SOCRATES: I understand the point you're making, Meno. Do you see what a contentious argument you are introducing—that a man cannot search either for what he knows or for what he does not know? He cannot search for what he knows, because he knows it, and there is no need to search. Nor can he search for what he does not know, because he doesn't know what to look for.
How then do we ever learn anything new?
Plato's response is radical: we don't actually learn new things—we remember them. The soul is immortal and has encountered all truths before birth. What we call "learning" is really recollection (Greek: ἀνάμνησις, anamnesis) of what we already knew but forgot when we were born into a body.
This means we never start from complete ignorance. We have "latent knowledge" that can be awakened through the right questions. The paradox dissolves because we're not acquiring something totally new—we're recognizing something familiar.
Socrates proves his theory by questioning an uneducated slave boy about geometry. Through questions alone—no teaching—the boy discovers how to double a square's area.
🤔 The slave boy "discovers" that the diagonal creates the double-area square. Does this prove he already KNEW it?
Critics argue Socrates didn't prove recollection—he asked highly structured questions that effectively taught the boy. The "discovery" was embedded in the questioning itself.
The mind comes pre-equipped with certain structures or concepts. We don't recollect from past lives, but our cognitive architecture enables certain types of knowledge acquisition.
There's a middle state between knowing and not-knowing: potential knowledge. We can know something in potentiality and actualize it through inquiry.
We can search without knowing exactly what we seek. We have criteria for recognition that guide inquiry. Finding the answer satisfies these criteria even if we couldn't specify them in advance.
The dialogue Meno (c. 385 BCE) is set in Athens. Meno, a wealthy Thessalian, asks Socrates whether virtue can be taught. This leads to the deeper question: can anything be taught or learned?
The paradox has profound implications:
The theory of recollection (anamnesis) becomes a cornerstone of Platonic philosophy, connecting to the Theory of Forms in later dialogues like the Phaedo and Republic.
