To all of our materialist friends who say that morality is subjective and determined by society:
John Davidson brings this to our attention:
A post at Get Religion caught my eye yesterday with the title, “Should Amazon tribes be allowed to kill their young? Foreign Policy editors aren’t sure.” It linked to a story in Foreign Policy magazine from April 9 about a handful of indigenous tribes in Brazil that engage in the ritual killing of infants and children—namely, those with a disability, twins, and the children of single mothers, all of whom are considered to be a bad omen—and the legal efforts underway to end the practice.
Now, our subjectivist friends have argued repeatedly that morality is determined by society. These tribes have determined that killing innocent children is an affirmatively good thing. I assume you agree that — for these tribes at least — killing innocent children is indeed an affirmatively good thing. If that is not what you think, please explain why.
