As time permits, I hope to share with you here my best recollections of the points that were raised in some of our discussions as well as some afterthoughts I might have had shortly afterwards. I won't try to directly quote anyone, including myself, for two reasons. First, memory being what it is, direct quotes would inevitably contain errors and I do not want to risk misrepresenting anyone's opinions. Second, I would like the points made here to stand on there own merit and to be taken for what they are worth. The goal is to stimulate your own thinking and to let you be your own judge as to the validity of these points independent of who might have voiced them.
