The only obligation which I have a right to assume is to do at any time what I think right.
Henry David ThoreauIndeed, the best books have a use, like sticks and stones, which is above or beside their design, not anticipated in the preface,not concluded in the appendix. Even Virgil's poetry serves a very different use to me today from what it did to his contemporaries. It has often an acquired and accidental value merely, proving that man is still man in the world.
