Single Idea 4433

[filed under theme 8. Modes of Existence / E. Nominalism / 4. Concept Nominalism ]

Full Idea

The standard objections to Predicate and Concept Nominalism are that some properties have no predicates or concepts, and that predicates and concepts seem to be types rather than particulars, and it is types the theory is seeking to analyse.

Gist of Idea

Concept and predicate nominalism miss out some predicates, and may be viciously regressive

Source

David M. Armstrong (Universals [1995], p.503)

A Reaction

The claim that some properties have no concepts is devastating if true, but may not be. The regress problem is likely to occur in any explanation of universals, I suspect.


The 14 ideas from 'Universals'

'Resemblance Nominalism' finds that in practice the construction of resemblance classes is hard [Armstrong]
'Resemblance Nominalism' says properties are resemblances between classes of particulars [Armstrong]
'Concept Nominalism' says a 'universal' property is just a mental concept applied to lots of things [Armstrong]
'Predicate Nominalism' says that a 'universal' property is just a predicate applied to lots of things [Armstrong]
Concept and predicate nominalism miss out some predicates, and may be viciously regressive [Armstrong]
'Class Nominalism' may explain properties if we stick to 'natural' sets, and ignore random ones [Armstrong]
'Class Nominalism' says that properties or kinds are merely membership of a set (e.g. of white things) [Armstrong]
'Class Nominalism' cannot explain co-extensive properties, or sets with random members [Armstrong]
'Mereological Nominalism' sees whiteness as a huge white object consisting of all the white things [Armstrong]
'Mereological Nominalism' may work for whiteness, but it doesn't seem to work for squareness [Armstrong]
One moderate nominalist view says that properties and relations exist, but they are particulars [Armstrong]
If properties and relations are particulars, there is still the problem of how to classify and group them [Armstrong]
It is claimed that some universals are not exemplified by any particular, so must exist separately [Armstrong]
Should we decide which universals exist a priori (through words), or a posteriori (through science)? [Armstrong]
