Single Idea 10750
[filed under theme 3. Truth / B. Truthmakers / 12. Rejecting Truthmakers
]
Full Idea
Slingshot Argument: if truth-makers work for equivalent sentences and co-referring substitute sentences, then if 'the numbers + S1 = the numbers' has a truth-maker, then 'the numbers + S2 = the numbers' will have the same truth-maker.
Gist of Idea
Slingshot Argument: seems to prove that all sentences have the same truth-maker

Book Ref
-: 'Mind' [-], p.73
A Reaction
[compressed] Hence every sentence has the same truth-maker! Truth-maker fans must challenge one of the premises.

[Oliver]
|
10724
