I am proud to be a heretic since 1965, when I first argued that an explanation in the class science book was bogus. (I was right.) Since then I have often found myself arguing a third point of view in arguments that seemed to have two sides. I am not always right but I always increase the likelihood that *somebody* is right.
Henry Jekyll was not exactly a heretic. It was not so much his views that were radical but his behavior. Instead of having a coherent philosophy of his own (as I recall the story) he was self-centered to the extent of wishing ill on anybody who was not pandering to him.
