I've read the messages that Dave Renfro refers to on the Swarthmore site and must say I found the comments interesting. I have a perspective different in some ways and similiar in others to those posting on that site. If anyone one reads these messages and is interested in my perspective, please post. I check in to see if anything new has been added to this topic every once in awhile. I had quite a lengthly response written in January but somehow made a mistake in the posting.
