Theory of Truth

Theory of Truth

A coherence theory of truth states that truth of any (true) proposition consists in its coherence with some specified set of propositions. The coherence theory differs from its principal competitor, correspondence theory of truth, in two essential respects. The competing ideas give inconsistent accounts of relative between propositions and their truth conditions. (In this article, 'proposition' is not utilized in any technical sense. It simply refers to bearers of reality values, whatever they may be.) According to one, relative is coherence, according to other, it is correspondence. The two ideas furthermore give conflicting accounts of reality conditions. According to coherence idea, reality conditions of propositions consist in other propositions. The correspondence theory, in compare, states that reality conditions of propositions are not (in general) propositions, but rather objective characteristics of world.

Versions of Coherence Theory of Truth

The coherence idea of truth has some versions. These versions disagree on two major issues. Different versions of idea give distinct anecdotes of coherence relation. Different diversity of idea furthermore give diverse accounts of set (or sets) of propositions with which factual propositions cohere. (I will mention to such the set as the specified set.)

According to some early versions of coherence theory, coherence relation is easily consistency. On this outlook, to state that the proposition coheres with the specified set of propositions is to state that proposition is consistent with set. This account of coherence is unsatisfactory for following reason. Consider two propositions which do not belong to the specified set. These propositions could both be consistent with the particular set and yet be inconsistent with each other. If coherence is consistency, coherence theorist would have to claim that both propositions are factual, but this is impossible.

Amore reasonable type of coherence idea states that coherence relation is some form of entailment. Entailment can be appreciated here as strict logical entailment, or entailment in some looser sense. According to this version, the proposition coheres with the set of propositions if and only if it is entailed by members of set. Another more reasonable type of idea, held for example in (Bradley 1914), is that coherence is mutual explanatory support between propositions.

The second issue on which coherence theorists (coherentists, for short) disagree is constitution of particular set of propositions. Coherentists usually acquiesce that particular set consists of propositions accepted or held to be true. They differ on inquiries of who believes propositions and when. At one farthest, coherence theorists can hold that specified set of propositions is largest reliable set of propositions actually accepted by genuine people. For such the type of idea, glimpse Young (1995). According to the moderate place, particular set consists of those propositions which will be accepted when persons like us (with finite cognitive capabilities) have reached some limit of inquiry. For such the coherence idea, glimpse Putnam (1981). At other extreme, coherence theorists can sustain that particular set comprises propositions which would be accepted by an omniscient being. Some idealists appear to accept this account of specified ...
