QUOTE : There are few books that set out what a mature person can believe - someone fully grown up, I mean. Aristotle's 'Ethics', Marcus Aurelius's 'Meditations', Montaigne's 'Essays', and the essays of Samuel Johnson come to mind. Even with these, we do not simply accept everything that is said. The author's voice is never our own, exactly; the author's life is never our own. It would be disconcerting, anyway, to find that another person holds precisely our views, responds with our particular sensibility, and thinks the same things important. Still, we gain from these books, weighing and pondering ourselves in their light. These books - and also some less evidently grown-up ones, Thoreau's 'Walden' and Nietzsche's writings, for example - invite or urge us to think along with them, branching in our own directions. We are not identical with the books we read, but neither would we be the same without them.
