As I just wrote on another brief blog entry, the dialogue on “Hitchens’s Second Question” has been continuing at a rapid pace for over a month now. It has now divided into two separate questions, and I’m opening up two new threads to deal with them separately.
The entry preceding this post is on whether there is grounding for morality outside of theism. This one is on whether such grounding really matters. Discussion on this thread should be focused on that topic.
To catch up on this discussion from the Hitchens thread, I suggest you begin here, and read at least three or four comments following that one.
Additional Explanation Added Tuesday Morning, per Charlie’s Advice:
The discussion here is not about moral behavior. Several of us worked hard in the earlier thread to keep that clear. It is also not about whether non-theists can live moral lives. That thread began (see the link above) with a strong affirmation that they can; in fact, some readers would consider it surprisingly strong. The discussion is about the grounding for moral duties and values, which I have defined loosely as
An answer to the question, “I don’t believe D moral duty or value applies to me, and I want you to tell me why I should. You might have some instrumental or pragmatic reasons for me to practice D, or you may tell me D is ‘what we customarily do in our culture,’ but I don’t know why D should be considered good in itself, or why I should take it on as a value or duty of my own.”
A proper ground for morals would be something that, if true and if understood by the subject (the questioner, in this case) to be true, would provide sufficient reason for the subject to change his or her mind about the goodness of the behavior, value, or duty in question. It would explain how said behavior, value or duty actually is good in itself; not merely instrumental, pragmatic, or customary.
It would do so by reference to some condition of reality that can bear the weight placed upon it. For example, if it is suggested that D is good because it contributes to reproductive fitness, then reproductive fitness’s goodness would have to be good in itself (or based on something else that is good in itself).
I apologize for being repetitious (this material was in the last blog entry), but I expect some readers to come to this blog entry without having read any others.
