Single Idea 12226

[filed under theme 7. Existence / D. Theories of Reality / 11. Ontological Commitment / a. Ontological commitment ]

Full Idea

Identity is sometimes read so that 'Pegasus is Pegasus' expresses a truth, the non-existence of any winged horse notwithstanding.

Clarification

Pegasus is a mythical winged horse

Gist of Idea

The identity of Pegasus with Pegasus may be true, despite the non-existence

Source

B Hale / C Wright (The Metaontology of Abstraction [2009], §5)

Book Ref

'Metametaphysics', ed/tr. Chalmers/Manley/Wasserman [OUP 2009], p.187


A Reaction

This would give you ontological commitment to truth, without commitment to existence. It undercuts the use of identity statements as the basis of existence claims, which was Frege's strategy.


The 10 ideas from 'The Metaontology of Abstraction'

It is a fallacy to explain the obscure with the even more obscure [Hale/Wright]
Are neo-Fregeans 'maximalists' - that everything which can exist does exist? [Hale/Wright]
Neo-Fregeanism might be better with truth-makers, rather than quantifier commitment [Hale/Wright]
The identity of Pegasus with Pegasus may be true, despite the non-existence [Hale/Wright]
Abstractionism needs existential commitment and uniform truth-conditions [Hale/Wright]
Equivalence abstraction refers to objects otherwise beyond our grasp [Hale/Wright]
Reference needs truth as well as sense [Hale/Wright]
Singular terms refer if they make certain atomic statements true [Hale/Wright]
Maybe we have abundant properties for semantics, and sparse properties for ontology [Hale/Wright]
A successful predicate guarantees the existence of a property - the way of being it expresses [Hale/Wright]
