Is the Allegory of the Cave a theory of education first and a metaphysics second?
Every year my students read the cave in Republic VII as a story about two worlds: shadows down here, Forms up there. That's not wrong, but I've come to think it isn't the emphasis Plato gives it.
Socrates introduces the image as a picture of our nature with respect to education and its lack. A few pages later (518b–d) he says education is not putting sight into blind eyes, as some teachers claim, but turning the whole soul around so it faces the right way. The prisoner isn't given new eyes; he is turned, dragged, dazzled, and slowly gets used to the light. Then he has to go back down.
So my question: does the epistemology of the cave really need the full theory of Forms? Or could we keep the account of learning (painful reorientation, habituation, the duty to return) and treat the metaphysics as optional?
