Well, seeing as how I still have the floor to myself, allow me to add the following closing comments:
Usually, morality is discussed with regard to how we can determine what is “good” or “bad” so as to permit us to choose how to act. Yes, the ultimate source of morality is important to know, but that is only a means the end of allowing us to make correct moral determinations. Without this stated purpose in mind, any discussion of morality becomes largely pointless. I believe that everybody who has posted to this thread (with one noticible exception) has done so with the expectation that the discussion would be held within this traditional framework.
The exception, of course, is TVAA. He (or she – I apologize if TVAA is, in fact a female) comes to this discussion with a preconceived belief that “everything that ever happens is inevitable; probability and choice are illusions.” If this is true, however, it is impossible for somebody to “choose” to act one way instead of another – we all act the way we do based on strict adherence to natural laws, and no amount of reason or intelligence can change that. It matters not that we all think we make choices, or that we frequently change our mind. According to TVAA, this is all an illusion.
If this is the case, however, it is meaningless to even discuss the nature or morality in the first place. What does it matter to know that morality is based on evolutionary principles if that knowledge cannot change our behavior? What does it matter if we were able to somehow determine “correct” moral systems through years of painstaking experimentation if we could not choose to follow those systems even after discovering them.
Morality asks, “Why should we choose to do one thing rather than another?” TVAA, on the other hand, states “choice is an illusion; we have no control over what we do in the first place. ‘Morality’ is naught but a description of how we act, and you can’t choose to change the way you act.”
Kind of defeats the pourpose of having a discussion in the first place, don’t you think?
