“Such terms as 'diagnosis' and 'pathology' are of course used analogically here, but I am using the word 'science' deliberate and unequivocally in its original and broad sense of discovery and knowing, rather than its conventional sense of isolating the secondary causes of natural phenomena. For if I believe anything, it is that the primary business of literature and art is cognitive, a kind of finding out and knowing and telling, both in good times and bad; a celebration of the way things are when they are right, and a diagnostic enterprise when they are wrong.”
