![]() Even in the mind of a single subject, consistency of beliefs is more demanding than coherence, but neither is very likely.Ĭoherence and consistency are best understood as desirable conditions for any theory of truth, including the correspondence theory of truth. In a system of belief as large as the culture of a society, there are many conflicting beliefs. The right kind is explanatory coherence, where explanation consists in describing mechanisms. But consistency is only possible for relatively modest logical and mathematical systems. The coherence theory is close to the consistency theory of truth. In this case, coherence is one way to justify a belief. A definition of this notion of truth is the following: A proposition p is true if and only if it coheres with a specified set of propositions The term coherence here can be considered in different ways. In traditional epistemology, the coherence may be internal to a personal set of beliefs that are accessible to a subject. The coherence theory of truth states that the truth of a proposition consists in its coherence with the other beliefs that are held. In analytic language philosophy, the truth of a proposition depends on its agreement with some larger set of propositions, ideally all known true propositions and any logical inferences from those propositions. In raising this as an objec-tion to the coherence theory of truth, Russell implies that on this view the truth of a proposition consists in its being a member. Charles Sanders Peirce's theory of pragmatic truth is the coherent inter-subjective agreement of an open community of inquirers. Typically, then, a coherence theory of truth would claim that the beliefs of a given individual are true to the extent that the set of all their beliefs is. Perfect coherence is not to be expected, of course. Put simply: a belief is true when we are able to incorporate it in an orderly and logical manner into a larger and complex system of beliefs or, even. The coherence theory differs from its principal competitor, the correspondence theory of truth, in two essential respects. The Coherence Theory of truth is probably second in popularity to the Correspondence Theory even though it often seems to be an accurate description of how our conception of truth actually works. In scientific theories, every new observational fact must be integrated with existing facts to make them maximally coherent. A coherence theory of truth states that the truth of any (true) proposition consists in its coherence with some specified set of propositions. In philosophies of idealism, all the ideas or beliefs are said to cohere with one another, perhaps because the world is reason itself or created by a rational agent. ![]() Adolphe Quételet Jürgen Renn Juan Roederer Jerome Rothstein David Ruelle Tilman Sauerīiosemiotics Free Will Mental Causation James SymposiumĪ coherence theory bases the truth of a belief on the degree to which it coheres ("hangs together") with all the other beliefs in a system of beliefs (typically one person's beliefs, but it could be any body of knowledge). The meaning of COHERENCE THEORY is the theory that the ultimate criterion of truth is the coherence of all its separate parts with one another and with.
