Conscience and the Moral Argument as Evidence for the Goodness of God.

[Fake Messiah]

every society has its morality, but each is different. What is deemed good in one society is often deemed bad in another; for instance, killing is immoral in most societies (under most but not all circumstances), but head-hunting is or was a valuable and appropriate behavior in some societies. In other words, morality is not absolute or universal, despite what you think, but relative.

If the majority of people in a society think slavery is OK, then is slavery moral in that time and place? 

Or is slavery always wrong, in your view?

As I explained many times, from humanistic perspective slavery is bad because a humanistic perspective is based on individual human feelings, and we know that slaves suffer. In Christian societies, the individual is not important, so that is why slavery was often acceptable (and many Christian apologists want it to come back) as is not allowing women to be educated, tolerance of other religions is not allowed, etc.

But there is no objective way for me to say that slavery is bad. I can only appeal to logic and humanistic appeals, which can easily be dismissed by a theistic mentality.
