Step 1: Recall Plato's Republic.
Plato, in The Republic, designs an ideal state governed by philosopher-kings. The dialogue includes his views on education, justice, and the role of different professions.
Step 2: Plato's suspicion of poets.
Plato criticizes poets and artists for being imitators of reality (mimesis). According to him, they produce mere "copies of copies" (shadows of truth), which can mislead and corrupt citizens by stirring emotions rather than promoting rational knowledge.
Step 3: Conclusion.
Thus, in the ideal Republic, Plato argued there is no proper place for poets, since they can destabilize moral and rational order.
