Non-Natural Properties
Non-Natural Properties
A notion which plays an important part in recent intuitionistic ethics. A non-natural property is one which is neither natural, as yellow and pleasantness are, nor metaphysical, as absoluteness and being commanded by God are. It is, then, a property which is apprehended, not by sensation or by introspection, but in some other way, and which is somehow non-descriptive, non-expository, or non-existential. It is also said sometimes, e.g. by G. E. Moore and W. D. Ross, to be a consequential property, i.e. a property which a thing has in virtue of its having another property, as when an experience is good in virtue of being pleasant. See Intuitionism. — W.K.F.
