What is the origin of ethical (moral) principles of human behavior. Many theists believe that religion provides the sole source of ethical principles. They say that one cannot have morals without religion. Secular humanists and others believe that ethical principles can be derived from reason, empiricism, and even evolution -- that religion is not required for developing sets of moral rules.
1) What do you think about this issue?
2) If God were shown not to exist (hypothetically!) would theists change their moral behavior. If so, in what ways?
the
codification of many moral practices among human groups has been done by the church. the church has been a staple of many societies and a religious gathering has been the center of a lot of social behavior. societies codify right/wrong behavior all the time, and if the strongest social arm in a community is a church then that will be where the codification takes place.
the
propensity for morality obviously out-dates the church, considering even the most rudimentary of family groups would have fallen apart long before any societal progress could be made without it. so this process of combining a propensity (recognition of incentive) for morality with the process of codification (training) had to have taken place AT LEAST before there were any 'holy documents' or even oral tradition (considering language is a product of group-forming) to set up any kind of religious influence.
i think if it were proven that there was no such thing as god it would change very little, it probably wouldn't even effect church attendance. but if everyone were to sincerely believe that there was no god, then you'd perhaps see a sudden, slight, spike in certain behaviors that were unduly repressed by religious doctrine (which for most of us wouldn't even be immoral). but overall, and over time, everyone would realize that we didn't need a babysitter, and that we are pretty good at doing this on our own.
