I have little time for ‘debunkings’ of flawed Christian arguments, although the arguments themselves annoy me: I just feel the effort is usually wasted, because everyone involved is already convinced in one direction or another, so nothing changes.
More than that, many such efforts seem to me to be unsophisticated, and to fall into many of the same fallacies and oversimplifications that they are railing against. I’d rather put time and energy into life.
Sometimes, though, someone does some careful work on the topic that I find interesting and enjoyable. I think (as a postmodernist) that all such efforts can be deconstructed in terms of their own internal logic, in the same way as the things they’re deconstructing, but it’s still interesting to talk/think about.
Here’s a short discussion by ‘Fedora’. Although it’s the end of the sequence, it’s probably a good place to start: http://urbanphilosophy.net/philosophy/trouble-in-paradise-on-biblical-morals/
Here are a couple of the earlier pieces mentioned in that piece: http://urbanphilosophy.net/religion/objective-morality-and-the-bible/, http://urbanphilosophy.net/religion/response-to-fedora-on-objective-morality-and-the-bible/, http://urbanphilosophy.net/religion/a-response-to-payton/.
Have fun, kids!
