It has always therefore been one of my main endeavors as a teacher to persuade the young that first-hand knowledge is not only more worth acquiring than second-hand knowledge, but is usually much easier and more delightful to acquire...Naturally, since I myself am a writer, I do not wish the ordinary reader to read no modern books. But if he must read only the new or only the old, I would advise him to read the old...A new book is still on its trial and the amateur is not in a position to judge it. It has to be tested against the great body of Christian thought down the ages, and all its hidden implications (often unsuspected by the author himself) have to be brought to light. Often it cannot be fully understood without the knowledge of a good many other modern books. If you join at eleven o'clock a conversation which began at eight you will often not see the real bearing if what is said...The only palliative is to keep the clean sea breeze of the centuries blowing through our minds, and this can be done only by reading old books.
-C.S. Lewis, excerpted from On the Reading of Old Books
