This research is an effort to understand the view of Plato on poetry and art; in other words, paying attention to the dispute between wisdom and poetic feeling and inspiration, in such a way that Plato tries to cut the imaginary wings of poetry with the razor of wisdom and encounter the human being with some realities which are appropriate to the true life. So he exiles Homer, as the representative of the poets and somehow the king of the poets to determine in turn the situation of some other low-rank poets. It is obvious that the hostility of Plato against the poets, whose works are as a general mirror of a exalted art, is not directed to Homer or a particular person. What Plato is in fight with is the undue posterity of poetry attaining an incorrect interpretation from concepts such as: justice, attributes of God, champions, fable stories etc. stated in an appropriate manner by the poets as the instructors of the time, youth and the polis. Plato himself had been writing tragedy in youth. After familiarity with Socrates, he put all of the works that had been composed before to fire. Nobody can deny the great influence of poetry on human soul. However, we should consider which poets are useful for human soul and paideia and which poets cause aberration and corruption of the youth's soul and the polis. Now we should see if there is a particular poet and art which deserves more consideration by Plato? In other words, opposition of Plato with poetry is an effort for proving the rightfulness of the philosophy as the most honorable art and constructing building block of human nature and Plato's polis on the rational criteria, a polis in which its governors and instructors are the philosophers not the poets.
