Answer:
This excerpt suggests that poetry is superior to other art forms.
Step-by-step explanation:
The text states that artists in general "has never equaled that of poets in the restricted sense of the term." In this sentence we can already see that the author of the text places poetry as an art superior to all others, an art form that can never be compared with other forms, because it reaches levels like neither music, nor painting, nor sculpture will achieve. The author also states that if we analyze in depth, not even the work of legislators and religious educators is greater and better than poetry and its effects.
