We possess the Canon because we are mortal and also rather belated. There is only so much time, and time must have a stop, while there is more to read than there ever was before. From the Yahwist and Homer to Freud, Kafka, and Beckett is a journey of nearly three millennia. Since that voyage goes past harbors as infinite as Dante, Chaucer, Montaigne, Shakespeare, and Tolstoy, all of whom amply compensate a lifetime's rereadings, we are in the pragmatic dilemma of excluding something else each time we read or reread extensively.
Harold BloomWhat is literary tradition? What is a classic? What is a canonical view of tradition? How are canons of accepted classics formed,and how are they unformed? I think that all these quite traditional questions can take one simplistic but still dialectical question as their summing up: do we choose tradition or does it choose us, and why is it necessary that a choosing take place, or a being chosen? What happens if one tries to write, or to teach, or to think, or even to read without the sense of a tradition? Why, nothing at all happens, just nothing.
