 Plato certainly mocks such a claim, just as, in the Ion, he mocks the rhapsode who believes he possesses a “science of poetry” or a “technique of poetic composition” (in 532c, Plato equivalently uses the words technê and epistêmê poiêtikê, or simply poiêtikê). In writing a “Treatise on poetic composition” (Peri poiêtikês), we can hypothesize that, unlike Plato, Aristotle followed the path indicated by Protagoras. And in publishing a more accessible work such as On Poets, Aristotle seems to take it for granted that every person should be offered the opportunity to become a good judge of poetry so that she can better appreciate the value of the poetry she reads or the plays she regularly goes to see in the theater.
