Singer comments that he 'regrets' he doesn't believe in God and that he seems to accept that only faith in a creator can properly ground objective morality.
Tim Mulgan, professor of moral and political philosophy at the University of St Andrews also offered some interesting comments. According to Vernon, he explained "why ethical objectivism may be vital to making a robust ethical case against environmental degradation." This is because "Only a doctrine of creation can affirm that we are fundamentally linked to the natural order manifest on Earth. The fantasy of fleeing this planet, or disappearing into virtual reality, won't actually do. Our island home matters because the lives of human beings go well only when her natural systems go well too. Or, as the psalmist intuited many centuries ago: "Truth shall spring out of the earth."
