What I desire for all my works, of course, is not merely a kind reader but also a frank critic. This is peculiarly my desire for this work, treating as it does of so tremendous a subject, in which one wishes as may discoverers of truth could be found as contradictors. But that last thing I want is a reader who is my doting partisan or a critic who is his own.
