The act of true reading is in its very essence democratic. Consider the nature of what happens when we read a book - and I mean, of course, a work of literature, not an instruction manual or a textbook - in private, unsupervised, un-spied-on, alone. It isn't like a lecture: it's like a conversation. There's a back-and-forthness about it. The book proposes, the reader questions, the book responds, the reader considers. We bring our own preconceptions and expectations, our own intellectual qualities, and our limitations, too, our own previous experiences of reading, our own temperament, our own hopes and fears, our own personality to the encounter.

Creation, whether it's writing, painting or whatever, is essentially despotic and autocratic in nature, because it's the work of one mind and one mind alone which has absolute power of life or death over this sentence, or that phrase or whatever it is. It brooks no interference and can only work if it's the one mind doing it. Reading, on the other hand, interpretation, is inherently, intrinsically democratic, because it is fundamentally a process of negotiation between the mind and the text, between the expectations you bring to it and the satisfactions and disappointments you take away from it.
