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.
Philip Pullman, The War on Words (2004)
