Intuitionism How can we come to know anything about non-natural properties? How might non-naturalists respond to the charge that they cannot explain supervenience?

Definist fallacy – Wikipedia

The Possibility of Metaphysics: In trying to make sense of the idea of moral perception of non-natural properties, some intuitionists have maintained that our ability to have veridical experiences of the moral properties is in virtue of our having a special faculty of mind whose function is to detect fgankena properties. An analogy with grammar illustrates the point.

University of California Press. This requirement seems plausible because the recognition that an frankwna is right plausibly is the recognition that the action is well-supported perhaps conclusively supported by justifying moral reasons for action, and such a recognition should motivate someone unless the agent is practically irrational.

Other Internet Resources [Please contact the author with fallaxy. More recently, some philosophers have argued that naturalism cannot capture the normativity of moral properties, and these arguments also seem to be very similar to the Open Question Argument. Once the naturalist allows that there naturalkstic non-moral evaluative properties that are relevant to the assessment of theories there is room for the non-naturalist to argue that moral evaluative properties need not be all that different metaphysically and epistemologically and hence no more problematic than the evaluative properties presupposed by the objection.


Views Read Edit View history. The first question might seem more difficult for the naturalist than for some non-naturalists; if goodness really is a sui generis non-natural property then perhaps being directly acquainted with it is sufficient for recognizing it as moral. History of Western Philosophy. The Naturalistic Fallacy in Meta-Ethics categorize this paper. He argues that the recognition of moral properties must have a sort of direct influence on the will so that anyone who recognizes them is thereby motivated.

Naturalisitc of these characterizations can be put to one side rather easily. The philosopher William Frankena first used the term definist fallacy in a paper published in the British analytic philosophy journal Mind in Naturalistkc is simply an empirical fact that those we take to be competent users of moral language do respect supervenience constraints and would think anyone frankenw did frankeja respect those constraints must be conceptually confused.

The naturalistic fallacy is very poorly named indeed a point also made by Bernard Williams; see Williams It could be relevant from the point of view of both such perspectives, but this would be for naturalism to be true, which, of course, is inconsistent with non-naturalism!

Naturalists, by contrast, are more likely to emphasize the importance of rejecting beliefs that fit poorly with our best scientific faolacy of reality; if common sense commits us to properties that do not fit well into that account then so much the worse for common sense.

So, for example, a view according to which goodness is the property of being commanded by God where God is understood as existing outside of Nature is also charged with having committed the naturalistic fallacy.

Definist fallacy

In effect, this would be to grant that the non-naturalist is right about the semantics moral predicates do purport to refer to non-natural properties but wrong about the metaphysics the non-naturalist is wrong to suppose moral predicates refer to anything. For not only is it not especially a problem for naturalists, it is also not really a fallacy even if Moore is right that it embodies a mistake of some kind.


Perhaps unsurprisingly, the Open Question Argument so understood still faces an impressive battery of objections. One such objection begins with the premise that non-natural properties do not figure in the best explanations of our experiences and observations.

After all, rationality is plausibly a normative notion and on some accounts see above it is the idea of normativity that gives the Open Question Argument its force.

Science Logic and Mathematics. See both Enoch and Fitzpatrick for relevant discussion grankena this last point. The idea is that moral knowledge is not literally perceptual in the first instance but is somehow very much like perceptual knowledge. Perhaps quasi-realists can avoid this specific worry about self-defeat by holding that moral properties are, after all, natural properties on their view.

Broad argued see Broadit is unclear how the roundness and brownness of a penny, for example, could exist in time by themselves. In light of this objection, Moore himself eventually abandoned this way of characterizing natural properties Moore A Philosophical Perspectiveby Richard Gaskin. The challenge is to provide a metaphysical account of how there could be properties like the properties to which the non-naturalist maintains our moral vocabulary purports to refer.
