In The Defence of Poesy, Philip Sidney expresses faith in poetry's ability to address ideas raised in both philosophy and history, but he argues that poetry engages with these topics better. He addresses the superiority of poetry by discussing classical philosophers:
Truly even Plato whosoever well considereth shall find that in the body of his work, though the inside and strength were philosophy, the skin, as it were, and beauty depended most of poetry.
Here, Sidney points out that in Aristotle's work, poetry forms the metaphoric skin that contains philosophical concepts within its form. To further sustain his argument through an appeal to ethos, he says,
Truly, Aristotle himself, in his discourse of poesy, plainly determineth this question, saying that poetry is philosophoteron and spoudaioterum, that is to say, it is more philosophical and more studiously serious than history.
By invoking Aristotle's arguments in his classical Greek text Poetics, Sidney argues that poetry is a superior medium because it involves and does better than philosophy and history. He paraphrases Aristotle's treatise on poetry and poetics, saying that "poesy dealeth with katholou," meaning "universal consideration," which philosophy and history are not able to fully render.
