Scientific truths include the measurement of net harm to society for any given action -- which then impact utilitarian consequentialistic morals. ("It's unjust to execute anyone. Ever.")
Scientific truths include observations as to what occurs "in nature" which then informs naturalistic morals ("It's not natural to be gay/left-handed/brilliant" )
Scientific truths include observations about the role morality plays in those species we can observe to possess it, thereby informing us practically about what actions or inactions or rules would best optimize that function. (Observing apes and other primates or pack animals to derive a functional analysis of how morality impacts our social coherence and so on.)
I have long argued that morality needn't be absolute in order to be objective. Moral relativism and moral objectivism may be standard terms but I assert they are not as incompatible as is routinely claimed.
We needn't know what is perfectly moral to know objectively what is less moral.
From Being a Realist (even if you believe in God):
My mother, who doesn't call herself a theist (I think she's agnostic), doesn't even accept realism. She doesn't even agree with this:
That's little more than tautologies here. Yet it elicited an impression of being forced to believe. I know because she told me about the totalitarian dangers from such narrow thinking.
I'm happy to have finally found the root cause of our ongoing disagreement, but now, how can I deal with that? It looks pretty hopeless, but just in case, does someone have a suggestion, or should I just leave it at that? (My ego doesn't like it, but giving up is an option.)
Now I'm relieved to know that in near mode, she's a complete realist. This craziness only shows up in far mode.
