"It is a good rule, after reading a new book, never to allow yourself another new one till you have read an old one in between. If that is too much for you, you should at least read one old one to every three new ones.... Keep the clean sea breeze of the centuries blowing through your mind ... by reading old books. Not, of course, that there is any magic about the past. People were no cleverer than they are now; they made as many mistakes as we. But not the same mistakes.... Two heads are better than one, not because either is infalliable, but because they are unlikely to go wrong in the same direction."
~ C.S. Lewis, from an introduction to "The Incarnation of the Word of God" by St Athanasius
