The Cave and the Idea of the Good

There isn't an actual sun, an actual line, an actual cave that's being sort of described here. These are all images for the 'good' And if we take the cave too seriously and we sort of accept it sort of whole hog, I think we just end up in glaucones position, which is unfortunate. Can I just say one more trap or arrogantly believing that we're out? Just one more thing right at the end of book six before we go to the allegory, the cave,. where he's talking about the idea of the good and the forms and the cave.
