Single Idea 18484
[filed under theme 3. Truth / B. Truthmakers / 1. For Truthmakers
]
Full Idea
For Martin the fatal error of phenomenalists was their inability to supply credible truth-makers for truths about unobserved objects; the same error afflicted Ryle's behaviourism, ...and Prior's Presentism (for past-tensed and future-tensed truths).
Gist of Idea
Phenomenalists, behaviourists and presentists can't supply credible truth-makers

A Reaction
This seems to be the original motivation for the modern rise of the truthmaker idea. Personally I find 'Napoleon won at Austerlitz' is a perfectly good past-tensed truthmaker which is compatible with presentism. Truth-making is an excellent challenge.
