Let me begin by expressing my gratitude to the various commentators for their remarks about Born to Rebel, including some of the constructive criticisms of my research findings and conclusions. No book trying to set forth more than two decades of research on why historical figures as diverse as Martin Luther and Charles Darwin behaved the way they did can expect to pass muster without exception. At best, one hopes that any problems that come to light will prove to be relatively easy to correct (as I think they have been, so far) and thus do not undermine the validity of the book's central arguments.
