Single Idea 4432
[filed under theme 8. Modes of Existence / E. Nominalism / 4. Concept Nominalism
]
Full Idea
Concept Nominalism says different things have the same property, or belong to the same kind, if the same concept in the mind is applied to different things.
Gist of Idea
'Concept Nominalism' says a 'universal' property is just a mental concept applied to lots of things
Source
David M. Armstrong (Universals [1995], p.503)
Book Ref
'A Companion to Metaphysics', ed/tr. Kim,Jaegwon/Sosa,Ernest [Blackwell 1995], p.503
A Reaction
This is more appealing than Predicate Nominalism, and may be right. Our perception of the 'properties' of a thing may be entirely dictated by human interests, not by nature.

|
|

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]
|
|
4434
|
'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

One moderate nominalist view says that properties and relations exist, but they are particulars
[Armstrong]
|
|
4445
|
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]
