Platonism is the view that there exist such things as abstract objects — where an abstract object is an object that does not exist in space or time and which is therefore entirely non-physical and nonmental. Platonism in this sense is a contemporary view. It is obviously related to the views of Plato in important ways, but it is not entirely clear that Plato endorsed this view, as it is defined here. In order to remain neutral on this question, the (...) term ‘platonism’ is spelled with a lower-case ‘p’. (See entry on Plato.) The most important figure in the development of modern platonism is Gottlob Frege (1884, 1892, 1893-1903, 1919). The view has also been endorsed by many others, including Kurt Gödel (1964), Bertrand Russell (1912), and W.V.O. Quine (1948, 1951). (shrink)

Abstractionists claim that the only bearers of intrinsic value are abstract, necessarily existing states of affairs. I argue that abstractionism cannot succeed. Though we can model concrete goods such as lives, projects, and outcomes with abstract states, conflating models of goods with the goods themselves has surprising and unattractive consequences. I suggest that concrete states of affairs or facts are the only bearers of intrinsic value. I show how this proposal can overcome the concerns lodged against abstractionism and, in the (...) process, reconnect us with the good. (shrink)
