Quote from Arthur James Balfour

"So it is with those persons who claim to show by their example that naturalism is practically consistent with the maintenance of ethical ideals with which naturalism has no natural affinity. Their spiritual life is parasitic: it is sheltered by convictions which belong, not to them, but to the society of which they form a part; it is nourished by processes in which they take no share. And when those convictions decay, and those processes come to an end, the alien life which they have maintained can scarce be expected to outlast them" 

Peter Singer

Peter Singer's philosophy is vile, and an example of what generates so much mistrust of our higher educational systems.  He's brilliant, intellectually speaking, and his logic is sound.  It's his presuppositions that lead to his monstrous conclusions. 

In this article he notes that, "There have been many critics of my views about euthanasia for severely disabled infants."

Yes, Mr. Singer there are and always will be.
