Question:
In the theistic view of morality, your current moral ideals are the will of God, therefore eternal, immutable, sacred, and unquestionable. But often, as we learn more, we DO begin to think we may need to change our views on certain of these ideals.
For example, the wisdom of the ages, for millennia, all around the world, to paraphrase the Bible, was "spare the rod, spoil the child". Physical punishment of children was seen as indispensable for raising disciplined, responsible, adults: "put the fear of God into them", "break their strong will", etc.... I once knew someone who remembered as a child playing quietly with her siblings and neighbors, and her mom would sometimes just come over and beat the tar out of her. Between blows, she would ask why she was getting beaten. The mom would answer that she wanted to be sure she wouldn't grow up spoiled and disrespectful. This was the wisdom of the ages.
But it wasn't until the 1960s when very large, detailed, systematic child psychology studies showed that this practice was not raising disciplined children, it was harmful. It taught them that might makes right, and it created fearful, hateful, and angry adults with lots of emotional and psychological problems. Other methods were found to be far more effective for discipline and child-rearing.
So the child psychology community has started to condemn physical child abuse. But a child psychologist once confided in me that the people they have the most trouble convincing to stop beating their kids are the religious people, who keep quoting them the "spare the rod, spoil the child" quotes, and continue with this dysfunctional practice, creating a lot of further problems for themselves and their children.
Now I don't want to get into a scientific debate here about whether child abuse is really a good method of child rearing or not. My point is that the facts, as best we currently know them, can guide the ethics. If further results come out that show that physical abuse of children is, indeed, a good method of child rearing, then we may change our mind yet again. It's like what we get with diet recommendations. The facts, as best we know them, can be a guide for the recommendations for what we should be doing, ie, the ethics.
But if you say you know the eternal, unquestionable, immutable truth, aren't you short circuiting this whole process? Aren't you closing your eyes, and mind, and ears, to any new information? Yes I know it feels better to feel like you can rise above all the contingencies and errors and blind alleys of trying to figure things out and learn more and growing. These are messy processes. But even if it helps you feel better, does it really lead to better outcomes? Should we be going back to trials by ordeal and witch burnings? Physical abuse of children? Looking to Biblical instructions on how to own and treat slaves? Telling women they should stay quiet in the churches because it is shameful for them to speak there?
So yes, I know the non-theistic morality is always contingent, open to questioning, and humble in its ethical recommendations and claims. I know the theistic position creates far more confidence and pride- you look on the poor, pathetic masses who don't know the final answer like you do. You must feel like the student who has gotten a hold of the teacher's answer book, and is watching all the other poor students struggling to figure out the problems on their own. But is that really the final answer book, or just something another student just made up based on their own best anwers at the time? Are the results necessarily better? Is the comfort you achieve from thinking you know the ultimate answers worth not wanting to put in the hard work of learning more and maybe trying to do better yet?
