It is only when we say a proposition that we speak truly or falsely [Sext.Empiricus]
|
|
Full Idea:
It is only when we say a proposition that we speak truly or falsely.
|
|
From:
Sextus Empiricus (Against the Professors (six books) [c.180], 8.74)
|
|
A reaction:
This makes assertions truth-bearers, rather than propositions. But a proposition can be true or false if it is stamped with a date and/or place. "Shakespeare was born in Stratford on 23rd April 1664". No one needs to assert that.

3. Truth / C. Correspondence Truth / 3. Correspondence Truth critique
2768
|
The correspondence theory also has the problem that two sets of propositions might fit the facts equally well [Dancy,J]
|
|
Full Idea:
The correspondence theory as well as the coherence theory has the problem of more than one set of truths. Why can't two sets of propositions "fit the facts" equally well?
|
|
From:
Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.2)
|
3. Truth / D. Coherence Truth / 1. Coherence Truth
2765
|
Rescher says that if coherence requires mutual entailment, this leads to massive logical redundancy [Dancy,J]
|
|
Full Idea:
Rescher complains that if coherence requires mutual entailment, then what is entailed is logically redundant, and the whole system is infected with mutual redundancy.
|
|
From:
Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.1)
|
2769
|
If one theory is held to be true, all the other theories appear false, because they can't be added to the true one [Dancy,J]
|
|
Full Idea:
From the point of view of someone with a theory every other theory is false, because it cannot be added to the true theory.
|
|
From:
Jonathan Dancy (Intro to Contemporary Epistemology [1985], 8.2)
|
3. Truth / D. Coherence Truth / 2. Coherence Truth Critique
2766
|
Even with a tight account of coherence, there is always the possibility of more than one set of coherent propositions [Dancy,J]
|
|
Full Idea:
No matter how tight our account of coherence we have to admit that there may be more than one set of coherent propositions (as Russell pointed out (1907)).
