Hamlet tells Horatio that there are more things in heaven and earth than are dreamt of in his philosophy. In Double Vision, philosopher and literary critic Tzachi Zamir argues that there are more things in Hamlet than are dreamt of--or at least conceded--by most philosophers. Making an original and persuasive case for the philosophical value of literature, Zamir suggests that certain important philosophical insights can be gained only through literature. But such insights cannot be reached if literature is deployed merely as an aesthetic sugaring of a conceptual pill. Philosophical knowledge is not opposed to, but is consonant with, the literariness of literature. By focusing on the experience of reading literature as literature and not philosophy, Zamir sets a theoretical framework for a philosophically oriented literary criticism that will appeal both to philosophers and literary critics.
