Aliza, what I mean by "One alternative to revealed morality is utter lack of any morality; that's not viable so let's not even discuss it" is not a deviation from which leaves open the possibility that the people or the individual are deviating towards an alternative. Utter lack of morality is not viable. By not viable I mean that the individual who entirely lacks morality is also entirely unable to relate to others and so will perish unless the society for some reason chooses to completely support him. Utter lack of morality is not viable for a society because what defines a society is a significant degree of coherence. The culture and the morality are bound together so that you cannot have one without the other. Utter lack of morality is therefore impossible.Here, I think you approach the core of the problem. In fact we must discuss what happens to a people, or to a person, when they deviate from *proper morality* and the intellectual foundation, as well as the spiritual foundation and seriousness, required to hold to the morality that you mention. In fact, that is really what the conversation -- any conversation we might have -- is really about. I mean, defining proper action. So, what we in fact must do is to discuss the deviation and what happens to people when they dissolve themselves from inner and outer authority.One alternative to revealed morality is utter lack of any morality; that's not viable so let's not even discuss it. The other alternative, now an established religious fact, is the morality of consensus among the growing population of free thinking individuals. Everything including the ethics of various moral systems has to be considered by free thinking individuals.
You still see God as the centre of the spiritual and material cosmos. But God is a human creation and thus there is no fixed point of reference; moral reference is the particular point we are discussing here and there is no fixed point of moral reference. We are not entirely bereft as we have a recorded past. Of course it's scary! It's revolutionary.
