Perry:
It is tempting to answer your questions. But I won't. There are hundreds of books that specifically deal with those issues.
Why don't you create your own characters and have them argue this out. When you reach closure then post the discussion on board.
T = Theist
A = Atheist
T= How do you live a moral life as an Atheist?
A=I behave morally even though there is NO God that's going to punish or reward me? I think that is a higher morality than yours.
T= The only reason you know about morality is that you were born into a world of Theists who have already worked out morality. And they have developed a set of laws that define correct human behavior.
A= The very existence of laws in a world of Theists is a contradiction. You wouldn't need laws if religion was up to the task of teaching people how they ought to behave and IF they really believed God will punish or reward them for their behavior.
etc. etc.
If this subject is of serious interest to you then you ought to construct an argue-log like the example above. Argue both sides. Do the research to make it interesting. The objective of argument is to arrive at truth.
A lot of the mega-post discussions on this board could be eliminated if people would learn to debate both sides of an issue BEFORE taking it public.
It's like watching chess players. The best chess players don't sit down to a game of chess without a knowledge of thousands of games. Watching novices play the game is boring. It is a sequence of stupid mistakes.
I think that's why guys like AlanF have given up discussing these subjects.
