 Philosophy entered literature in the dialogues of Plato, who converted the give and take of Socratic questioning into written form.Aristotle, Plato's student, wrote dozens of works on many scientific disciplines, but his greatest contribution to literature was likely his "Poetics", which lays out his understanding of drama, and thereby establishes the first criteria for literary criticism.The New Testament is an unusual collection of texts--John's "Book of Revelation", though not the first of its kind, essentially defines apocalypse as a literary genre.
