Ethicist David Brink states: "There might be no objective moral standards...but this would be a revisionary conclusion, to be accepted only as the result of extended and compelling argument that the commitments of ethical objectivity are unsustainable." (David O. Brink, "The Autonomy of Ethics," in The Cambridge Companion to Atheism, pg. 149)
Naturalistic Philosopher of Science Michael Ruse states: "The man who says that it is morally acceptable to rape little children is just as mistaken as the man who says 2+2=5." (Michael Ruse, Darwinism Defended, pg.275)
Dr. Louise Anthony states: Any argument for moral scepticism will based upon premises which are less obvious than the existence of objective moral values themselves. (Taken from speech during the Debate on the Foundations of Morality with Dr. William Lane Craig)
Atheist Sam Harris confesses that objective moral values and duties exist, but maintains that they are ontologically grounded solely in the brain.
Atheist Richard Dawkins repeatedly cries out at what he perceives to be objectively wrong acts such as "religious indoctrination" of children, and homosexual discrimination, among others.
We all apprehend a realm of objective moral values and duties. We all (or rather all that are in their right mind) admit that it is wrong to torture, rape, and kill little children, among other reprehensible acts. We maintain that these acts are wrong, independent of people's beliefs, and independent of a society's general consensus of whether it is permissible.
