Coherence theories differ over the coherence relation, and over the set of proposition with which to cohere [Young,JO]
|
|
Full Idea:
Coherence theories of truth differ on their accounts of the coherence relation, and on their accounts of the set (or sets) of propositions with which true propositions occur (the 'specified set').
|
|
From:
James O. Young (The Coherence Theory of Truth [2013], §1)
|
|
A reaction:
Coherence is clearly more than consistency or mutual entailment, and I like to invoke explanation. The set has to be large, or the theory is absurd (as two absurdities can 'cohere'). So very large, or very very large, or maximally large?

Two propositions could be consistent with your set, but inconsistent with one another [Young,JO]
|
|
Full Idea:
It is unsatisfactory for the coherence relation to be consistency, because two propositions could be consistent with a 'specified set', and yet be inconsistent with each other. That would imply they are both true, which is impossible.
|
|
From:
James O. Young (The Coherence Theory of Truth [2013], §1)
|
|
A reaction:
I'm not convinced by this. You first accept P because it is consistent with the set; then Q turns up, which is consistent with everything in the set except P. So you have to choose between them, and might eject P. Your set was too small.

Coherence with actual beliefs, or our best beliefs, or ultimate ideal beliefs? [Young,JO]
|
|
Full Idea:
One extreme for the specified set is the largest consistent set of propositions currently believed by actual people. A moderate position makes it the limit of people's enquiries. The other extreme is what would be believed by an omniscient being.
|
|
From:
James O. Young (The Coherence Theory of Truth [2013], §1)
|
|
A reaction:
One not considered is the set of propositions believed by each individual person. Thoroughgoing relativists might well embrace that one. Peirce and Putnam liked the moderate one. I'm taken with the last one, since truth is an ideal, not a phenomenon.

If you know your father, but don't recognise your father veiled, you know and don't know the same person [Eubulides, by Dancy,R]
|
|
Full Idea:
The 'undetected' or 'veiled' paradox of Eubulides says: if you know your father, and don't know the veiled person before you, but that person is your father, you both know and don't know the same person.
|
|
From:
report of Eubulides (fragments/reports [c.390 BCE]) by R.M. Dancy - Megarian School
|
|
A reaction:
Essentially an uninteresting equivocation on two senses of "know", but this paradox comes into its own when we try to give an account of how linguistic reference works. Frege's distinction of sense and reference tried to sort it out (Idea 4976).

Removing one grain doesn't destroy a heap, so a heap can't be destroyed [Eubulides, by Dancy,R]
|
|
Full Idea:
The 'sorites' paradox of Eubulides says: if you take one grain of sand from a heap (soros), what is left is still a heap; so no matter how many grains of sand you take one by one, the result is always a heap.
|
|
From:
report of Eubulides (fragments/reports [c.390 BCE]) by R.M. Dancy - Megarian School
|
|
A reaction:
(also Cic. Acad. 2.49) This is a very nice paradox, which goes to the heart of our bewilderment when we try to fully understand reality. It homes in on problems of identity, as best exemplified in the Ship of Theseus (Ideas 1212 + 1213).

Are truth-condtions other propositions (coherence) or features of the world (correspondence)? [Young,JO]
|
|
Full Idea:
For the coherence theory of truth, the truth conditions of propositions consist in other propositions. The correspondence theory, in contrast, states that the truth conditions of propositions are ... objective features of the world.
|
|
From:
James O. Young (The Coherence Theory of Truth [2013], Intro)
|
|
A reaction:
It is obviously rather important for your truth-conditions theory of meaning that you are clear about your theory of truth. A correspondence theory is evidently taken for granted, even in possible worlds versions.

Coherence truth suggests truth-condtions are assertion-conditions, which need knowledge of justification [Young,JO]
|
|
Full Idea:
Coherence theorists can argue that the truth conditions of a proposition are those under which speakers tend to assert it, ...and that speakers can only make a practice of asserting a proposition under conditions they can recognise as justifying it.
|
|
From:
James O. Young (The Coherence Theory of Truth [2013], §2.2)
|
|
A reaction:
[compressed] This sounds rather verificationist, and hence wrong, since if you then asserted anything for which you didn't know the justification, that would remove its truth, and thus make it meaningless.
