Attack on the Republic

I found the flaw in Plato's republic's attack on Art. because his ideals and ideas which are the only truths. the only way to leave the cave. The only way to be philosopher king stem from faith and belief whose cornerstone is imagination and knowledge of nature. Plato's ideals might exist but it requires the power of imagination to recognize and believe in them. Art is no different it's cornerstone is imagination as well and formed by knowledge. His ideals are art.
