Moral Error Theory
Moral error theory is a position characterized by its commitment to two propositions: (i) all moral claims are false and (ii) we have reason to believe that all moral claims are false. The most famous moral error theorist is J. L. Mackie, who defended the metaethical view in Ethics: Inventing Right and Wrong (1977). Mackie has been interpreted as giving two arguments for moral error theory.
The first argument people attribute to Mackie, often called the Argument from Queerness, holds that moral claims imply motivation internalism (the doctrine that "It is necessary and a priori that any agent who judges that one of his available actions is morally obligatory will have some (defeasible) motivation to perform that action" ). Because motivation internalism is false, however, so too are all moral claims.
The other argument often attributed to Mackie, often called the Argument from Disagreement, maintains that any moral claim (e.g. "Killing babies is wrong") entails a correspondent "reasons claim" ("one has reason not to kill babies"). Put another way, if "killing babies is wrong" is true then everybody has a reason to not kill babies. This includes the psychopath who takes great pleasure from killing babies, and is utterly miserable when he does not have their blood on his hands. But, surely, (if we assume that he will suffer no reprisals) this psychopath has every reason to kill babies, and no reason not to do so. All moral claims are thus false.

Famous quotes containing the words moral, error and/or theory:
“There exists in a great part of the Northern people a gloomy diffidence in the moral character of the government. On the broaching of this question, as general expression of despondency, of disbelief that any good will accrue from a remonstrance on an act of fraud and robbery, appeared in those men to whom we naturally turn for aid and counsel. Will the American government steal? Will it lie? Will it kill?—We ask triumphantly.”
—Ralph Waldo Emerson (1803–1882)
“Custom calls me to’t.
What custom wills, in all things should we do’t,
The dust on antique time would lie unswept,
And mountainous error be too highly heaped
For truth to o’erpeer.”
—William Shakespeare (1564–1616)
“... the first reason for psychology’s failure to understand what people are and how they act, is that clinicians and psychiatrists, who are generally the theoreticians on these matters, have essentially made up myths without any evidence to support them; the second reason for psychology’s failure is that personality theory has looked for inner traits when it should have been looking for social context.”
—Naomi Weisstein (b. 1939)
