Cognitivism encompasses all forms of
moral realism, but cognitivism can also agree with ethical
irrealism or
anti-realism. Aside from the
subjectivist branch of cognitivism, some cognitive irrealist theories accept that ethical sentences can be objectively true or false, even if there
exist no natural, physical or in any way
real (or "
worldly")
entities or
objects to make them true or false. There are a number of ways of construing how a proposition can be objectively true without corresponding to the world: • By the
coherence rather than the
correspondence theory of truth • In a figurative sense: it can be true that I have a cold, but that doesn't mean that the word "cold" corresponds to a distinct entity. • In the way that mathematical statements are true for
mathematical anti-realists. This would typically be the idea that a proposition can be true if it is an entailment of some intuitively appealing
axiom—in other words,
a priori analytical reasoning.
Crispin Wright,
John Skorupski and some others defend normative cognitivist irrealism. Wright asserts the extreme implausibility of both
J. L. Mackie's error-theory and
non-cognitivism (including
S. Blackburn's
quasi-realism) in view of both everyday and sophisticated moral speech and argument. The same point is often expressed as the
Frege-Geach Objection. Skorupski distinguishes between receptive awareness, which is not possible in
normative matters, and non-receptive awareness (including dialogical knowledge), which is possible in normative matters.
Hilary Putnam's book
Ethics without Ontology (
Harvard, 2004) argues for a similar view, that ethical (and for that matter
mathematical) sentences can be true and
objective without
there being any objects to make them so. Cognitivism points to the
semantic difference between
imperative sentences and
declarative sentences in normative subjects. Or to the different meanings and purposes of some superficially declarative sentences. For instance, if a teacher allows one of her students to go out by saying "You may go out", this sentence is neither true nor false. It
gives a permission. But, in most situations, if one of the students asks one of his classmates whether she thinks that he may go out and she answers "Of course you may go out", this sentence is either true or false. It does not
give a permission, it states that
there is a permission. Another argument for ethical cognitivism stands on the close resemblance between ethics and other normative matters, such as
games. As much as
morality, games consist of norms (or
rules), but it would be hard to accept that it be not true that the
chessplayer who checkmates the other one wins the game. If statements about game rules can be true or false, why not ethical statements? One answer is that we may want ethical statements to be
categorically true, while we only need statements about right action to be
contingent on the acceptance of the rules of a particular game—that is, the choice to play the game according to a given set of rules. == See also ==
