Presumably, the allegory of the cave illustrates that true knowledge is not sensible in nature (which gives us only "opinions" or "beliefs" as Plato illustrates in the preceeding doctrine of the divided line) , but only achieved by reason in its understanding of the Forms (the sun being a metaphor for the "good-itself" or the "good beyond being" or for the system of the Forms).
