Ethical intuitionism (also called moral intuitionism) is a family of views in moral epistemology (and, on some definitions, metaphysics). At minimum, ethical intuitionism is the thesis that our intuitive awareness of value, or intuitive knowledge of evaluative facts, forms the foundation of our ethical knowledge.
The view is at its core a foundationalism about moral beliefs: it is the view that some moral truths can be known non-inferentially (i.e., known without one needing to infer them from other truths one believes).
Such an epistemological view implies that there are moral beliefs with propositional contents; so it implies cognitivism.

Traditionally, intuitionism was often understood as having several other commitments:
- Moral realism, the view that there are objective facts of morality (as held by Mark Platts).
- Ethical non-naturalism, the view that these evaluative facts cannot be reduced to natural fact.
- Classical foundationalism, i.e., the view that intuited moral beliefs are: infallible (indefeasible), indubitable (irresistibly compelling), incorrigible, certain, or understandable without reflection.
- The view that moral intuitions are produced by a single, special, dedicated faculty in the mind.
- The view that moral properties are "simple" (as held by G.E. Moore).
- The view that moral truths are knowable only by intuition.
Secondly, sometimes the term "ethical intuitionism" is associated with a pluralistic, deontological position in normative ethics, a position defended by both G.E. Moore and W.D. Ross. However, as is customary in contemporary philosophy, the term "ethical intuitionism" will be used in this article to refer to the general position that there are basic (non-inferential) moral beliefs. Thus, this usage encompasses both empiricist and rationalist accounts of non-inferential moral knowledge. While the empiricist version of ethical intuitionism is standardly called "moral sense theory" (or sometimes "sentimentalism"), there is no standard name for the rationalist version. In this article, the rationalist version of ethical intuitionism will simply be called "rationalist ethical intuitionism".
Robert Audi (2004, Ch. 1) points out that in applied ethics, philosophers frequently appeal to intuitions to justify their claims, even though they do not call themselves intuitionists. Audi hence uses the label "intuitivists" to refer to people who are intuitionists without labeling themselves as such.
On this broad understanding of intuitionism, there are only a few ways someone doing moral philosophy might not count as an intuitionist. First, they might really refrain from relying on intuitions in moral philosophy altogether (say, by attempting to derive all moral claims from claims about what certain individuals desire). Second, they might deny foundationalism in favor of (say) coherentism. Third, they might be non-cognitivists, holding that moral "beliefs" aren't really beliefs at all.
Rational intuition versus moral sense
Some use the term "ethical intuitionism" in moral philosophy to refer to the general position that we have some non-inferential moral knowledge (see Sinnott-Armstrong, 2006a & 2006b)--that is, basic moral knowledge that is not inferred from or based on any proposition. However, it is important to distinguish between empiricist versus rationalist models of this. Some, thus, reserve the term "ethical intuitionism" for the rationalist model and the term "moral sense theory" for the empiricist model (see Sinnott-Armstrong, 2006b, pp. 184–186, especially fn. 4). However, the terminology is not ultimately important, so long as one keeps in mind the relevant differences between these two views.
Generally speaking, rationalist ethical intuitionism models the acquisition of such non-inferential moral knowledge on a priori, non-empirical knowledge, such as knowledge of mathematical truths; whereas moral sense theory models the acquisition of such non-inferential moral knowledge on empirical knowledge, such as knowledge of the colors of objects (see moral sense theory).
The rationalist version of ethical intuitionism models ethical intuitions on a priori, non-empirically-based intuitions of truths, such as basic truths of mathematics. Take for example the belief that two minus one is one. This piece of knowledge is often thought to be non-inferential in that it is not grounded in or justified by some other proposition or claim. Rather, one who understands the relevant concepts involved in the proposition that two minus one is one has what one might call an "intuition" of the truth of the proposition. One intuits the truth of the proposition, rather than inferring it. Likewise, the ethical intuitionist claims that basic moral truths—whether they are principles (such as don't kill people) or judgments (such as it is wrong to kill people)--are known without inference, and in particular they are known via one's rational intuition.
Some rationalist ethical intuitionists characterize moral "intuitions" as a species of belief (for example, Audi, 2005, pp. 33–6) that are self-evident in that they are justified simply by virtue of one's understanding of the proposition believed. Others characterize "intuitions" as a distinct kind of mental state, in which something seems to one to be the case (whether one believes it or not) as a result of intellectual reflection. Michael Huemer (2005), for example, defines "intuition" as a sort of seeming:
Reasoning sometimes changes how things seem to us. But there is also a way things seem to us prior to reasoning; otherwise, reasoning could not get started. The way things seem prior to reasoning we may call an 'initial appearance'. An initial, intellectual appearance is an 'intuition'. That is, an intuition that p is a state of its seeming to one that p that is not dependent on inference from other beliefs and that results from thinking about p, as opposed to perceiving, remembering, or introspecting. An ethical intuition is an intuition whose content is an evaluative proposition. (§5.2)
Regardless of one's definition of rational intuition, intuitionists all agree that rational intuitions are not justified by inference from a separate belief.
Another version---what one might call the empiricist version---of ethical intuitionism models non-inferential ethical knowledge on sense perception. This version involves what is often called a "moral sense". According to moral sense theorists, certain moral truths are known via this moral sense simply on the basis of experience, not inference.
One way to understand the moral sense is to draw an analogy between it and other kinds of senses. Beauty, for example, is something we see in some faces, artworks and landscapes. We can also hear it in some pieces of music. We clearly do not need an independent aesthetic sense faculty to perceive beauty in the world. Our ordinary five senses are quite enough to observe it, though merely observing something beautiful is no guarantee that we can observe its beauty. In the same way, a color-blind person is not necessarily able to perceive the green color of grass although he is capable of vision. Suppose we give a name to this ability to appreciate the beauty in things we see: one might call it the aesthetic sense. This aesthetic sense does not come automatically to all people with perfect vision and hearing, so it is fair to describe it as something extra, something not wholly reducible to vision and hearing. As the aesthetic sense informs us about what is beautiful, we can analogically understand the moral sense as informing us of what is good. People with a functioning moral sense get a clear impression of wrongness when they see puppies being kicked, for example.
Ethical Intuitionism was popular in the early twentieth century, particularly among British analytic philosophers.
H.A. Prichard gave an early defense of the view in his "Does Moral Philosophy Rest on a Mistake?" (1912), wherein he contended that moral philosophy rested chiefly on the desire to provide arguments starting from non-normative premises for the principles of obligation that we pre-philosophically accept, such as the principle that one ought to keep one's promises or that one ought not to steal. This is a mistake, Prichard argued, both because it is impossible to derive any statement about what one ought to do from statements not concerning obligation (even statements about what is good), and because there is no need to do so since common sense principles of moral obligation are self-evident.
Prichard was influenced by G.E. Moore, whose Principia Ethica (1903) argued famously that goodness was an indefinable, non-natural property of which we had intuitive awareness. Moore originated the term "the naturalistic fallacy" to refer to the (alleged) error of confusing goodness with some natural property, and he deployed the Open Question Argument to show why this was an error. Unlike Prichard, Moore thought that one could derive principles of obligation from propositions about what is good.
Ethical intuitionism suffered a dramatic fall from favor by the middle of the century, probably due in part to the influence of logical positivism, in part to the rising popularity of naturalism in philosophy, and in part to philosophical objections based on the phenomenon of widespread moral disagreement.
Some recent work suggests the view may be enjoying a resurgence of interest in academic philosophy. Robert Audi is one of the main supporters of ethical intuitionism in our days. His 2005 book, The Good in the Right, claims to update and strengthen Rossian intuitionism and to develop the epistemology of ethics. Michael Huemer's book Ethical Intuitionism (2005) also provides a recent defense of the view. Furthermore, authors writing on normative ethics often accept methodological intuitionism as they present allegedly obvious or intuitive examples or thought experiments as support for their theories.

Are there really objective moral values?
Many people think that beauty is subjective, that it is "in the eye of the beholder." They would claim there are really no objective facts about what is and is not beautiful, only facts about what people prefer. Because of the close analogies between the moral and the aesthetic sense, parity of reasoning suggests that we should see the difference between right and wrong as also being merely in the eye of the beholder. Though ethical intuitionists insist on the analogy, they equally insist that the facts about right and wrong are perfectly objective. How can they have it both ways?
Ethical intuitionists could respond by arguing that the moral-aesthetic analogy is merely used to illustrate the fact that not all senses are limited to the five physical senses. However, this doesn't necessarily imply any further connection between the moral and aesthetic senses.
The problem is made worse by the fact that there is so much widespread and apparently irresolveable disagreement about moral values. Why do these not get settled through the careful use of the moral sense? There are no long disputes about whether some object is green – these would be quickly settled if we just invited the disputing parties to look. Why does the moral sense not settle moral disagreements in a similarly simple way?
Ethical intuitionists could respond by pointing to numerous long-standing debates in philosophy and science. There are no long disputes about whether some object is green because that's simply a matter of observation, whereas metaphysics, epistemology, evolution, and quantum mechanics require reason, which is prone to human error. A similar analogy could be made about moral sense, which might give us a clear idea of what "rightness" is, but perhaps doesn't grant us direct knowledge of normative ethics.
It is undeniable that humans experience a feeling of right and wrong, but are these feelings evidence of an independent feature of the world? The principle of Occam’s Razor suggests that we postulate only those entities which are necessary to best explain our observations. The existence of an objective wrongness is not necessary to explain our queasy and resentful feelings. Thus, according to the principle, we should say there is no such thing as wrongness, and perhaps looks toward an explanation such as emotivism to explain the meanings of our sentences about wrongness.
A counter-objection is that the very fact we do postulate the independent feature regarding morals is indicative, and the fact we do not feel the need to do this for queasiness is itself an argument for objective morality. Moral sense might inform us of the existence of objective morality, just as eyesight informs us of the existence of colors. Occam's Razor wouldn't dismiss the existence of eyesight or colors, but would require the simplest explanation of how they work.
