A Coherence Theory of Truth and Knowledge

Truth is the property of being in accord with fact or reality. Truth is usually held to be the opposite of falsehood. The concept of truth is discussed and debated in various contexts, including philosophy, art, theology, and science. Most human activities depend upon the concept, where its nature as a concept is assumed rather than being a subject of discussion; these include most of the sciences , law , journalism , and everyday life. Some philosophers view the concept of truth as basic, and unable to be explained in any terms that are more easily understood than the concept of truth itself.

This is called the correspondence theory of truth. Various theories and views of truth continue to be debated among scholars, philosophers, and theologians. Is it even possible to give an informative definition of truth? What things are truthbearers and are therefore capable of being true or false? Are truth and falsehood bivalent , or are there other truth values? What are the criteria of truth that allow us to identify it and to distinguish it from falsehood?

What role does truth play in constituting knowledge? And is truth always absolute , or can it be relative to one's perspective? All Germanic languages besides English have introduced a terminological distinction between truth "fidelity" and truth "factuality".

Romance languages use terms following the Latin veritas , while the Greek aletheia , Russian pravda , South Slavic istina and Sanskrit sat related to English sooth and North Germanic sanna have separate etymological origins.

In some modern contexts, the word "truth" is used to refer to fidelity to an original or standard. It can also be used in the context of being "true to oneself" in the sense of acting with authenticity.

The question of what is a proper basis for deciding how words, symbols, ideas and beliefs may properly be considered true, whether by a single person or an entire society, is dealt with by the five most prevalent substantive theories of truth listed below.

Each presents perspectives that are widely shared by published scholars. Theories other than the most prevalent substantive theories are also discussed. More recently developed " deflationary " or "minimalist" theories of truth have emerged as possible alternatives to the most prevalent substantive theories.

Minimalist reasoning centres around the notion that the application of a term like true to a statement does not assert anything significant about it, for instance, anything about its nature.

Minimalist reasoning realises truth as a label utilised in general discourse to express agreement, to stress claims, or to form general assumptions. Correspondence theories emphasize that true beliefs and true statements correspond to the actual state of affairs.

It is a traditional model tracing its origins to ancient Greek philosophers such as Socrates , Plato , and Aristotle. A classic example of correspondence theory is the statement by the thirteenth century philosopher and theologian Thomas Aquinas : " Veritas est adaequatio rei et intellectus " "Truth is the adequation of things and intellect " , which Aquinas attributed to the ninth century Neoplatonist Isaac Israeli.

Correspondence theory centres heavily around the assumption that truth is a matter of accurately copying what is known as " objective reality " and then representing it in thoughts, words and other symbols. The German word Zeitgeist is one such example: one who speaks or understands the language may "know" what it means, but any translation of the word apparently fails to accurately capture its full meaning this is a problem with many abstract words, especially those derived in agglutinative languages.

Thus, some words add an additional parameter to the construction of an accurate truth predicate. Among the philosophers who grappled with this problem is Alfred Tarski , whose semantic theory is summarized further below in this article. Proponents of several of the theories below have gone further to assert that there are yet other issues necessary to the analysis, such as interpersonal power struggles, community interactions, personal biases and other factors involved in deciding what is seen as truth.

For coherence theories in general, truth requires a proper fit of elements within a whole system. Very often, though, coherence is taken to imply something more than simple logical consistency; often there is a demand that the propositions in a coherent system lend mutual inferential support to each other. So, for example, the completeness and comprehensiveness of the underlying set of concepts is a critical factor in judging the validity and usefulness of a coherent system.

Among the assortment of perspectives commonly regarded as coherence theory, theorists differ on the question of whether coherence entails many possible true systems of thought or only a single absolute system. Some variants of coherence theory are claimed to describe the essential and intrinsic properties of formal systems in logic and mathematics.

On the whole, coherence theories have been rejected for lacking justification in their application to other areas of truth, especially with respect to assertions about the natural world , empirical data in general, assertions about practical matters of psychology and society, especially when used without support from the other major theories of truth.

Coherence theories distinguish the thought of rationalist philosophers, particularly of Baruch Spinoza , Gottfried Wilhelm Leibniz , and Georg Wilhelm Friedrich Hegel , along with the British philosopher F.

The three most influential forms of the pragmatic theory of truth were introduced around the turn of the 20th century by Charles Sanders Peirce , William James , and John Dewey.

Although there are wide differences in viewpoint among these and other proponents of pragmatic theory, they hold in common that truth is verified and confirmed by the results of putting one's concepts into practice. Peirce defines truth as follows: "Truth is that concordance of an abstract statement with the ideal limit towards which endless investigation would tend to bring scientific belief, which concordance the abstract statement may possess by virtue of the confession of its inaccuracy and one-sidedness, and this confession is an essential ingredient of truth.

Although Peirce uses words like concordance and correspondence to describe one aspect of the pragmatic sign relation , he is also quite explicit in saying that definitions of truth based on mere correspondence are no more than nominal definitions, which he accords a lower status than real definitions.

William James 's version of pragmatic theory, while complex, is often summarized by his statement that "the 'true' is only the expedient in our way of thinking, just as the 'right' is only the expedient in our way of behaving. Though not widely known, a new variation of the pragmatic theory was defined and wielded successfully from the 20th century forward.

Defined and named by William Ernest Hocking , this variation is known as "negative pragmatism". Essentially, what works may or may not be true, but what fails cannot be true because the truth always works. For Peirce, the idea of " As Feynman noted, an idea or theory " Pragmatism and negative pragmatism are also closely aligned with the coherence theory of truth in that any testing should not be isolated but rather incorporate knowledge from all human endeavors and experience.

The universe is a whole and integrated system, and testing should acknowledge and account for its diversity. As Feynman said, " Social constructivism holds that truth is constructed by social processes, is historically and culturally specific, and that it is in part shaped through the power struggles within a community.

Constructivism views all of our knowledge as "constructed," because it does not reflect any external "transcendent" realities as a pure correspondence theory might hold.

Rather, perceptions of truth are viewed as contingent on convention, human perception, and social experience. It is believed by constructivists that representations of physical and biological reality, including race , sexuality , and gender , are socially constructed. Giambattista Vico was among the first to claim that history and culture were man-made.

Vico's epistemological orientation gathers the most diverse rays and unfolds in one axiom— verum ipsum factum —"truth itself is constructed". Hegel and Marx were among the other early proponents of the premise that truth is, or can be, socially constructed. Marx, like many critical theorists who followed, did not reject the existence of objective truth but rather distinguished between true knowledge and knowledge that has been distorted through power or ideology.

For Marx, scientific and true knowledge is "in accordance with the dialectical understanding of history" and ideological knowledge is "an epiphenomenal expression of the relation of material forces in a given economic arrangement". Consensus theory holds that truth is whatever is agreed upon, or in some versions, might come to be agreed upon, by some specified group. Such a group might include all human beings, or a subset thereof consisting of more than one person.

In the Islamic tradition, this principle is exemplified by the hadith in which Muhammad states, "My community will never agree upon an error" [38]. Modern developments in the field of philosophy have resulted in the rise of a new thesis: that the term truth does not denote a real property of sentences or propositions.

This thesis is in part a response to the common use of truth predicates e. In common parlance, truth predicates are not commonly heard, and it would be interpreted as an unusual occurrence were someone to utilise a truth predicate in an everyday conversation when asserting that something is true. Newer perspectives that take this discrepancy into account and work with sentence structures that are actually employed in common discourse can be broadly described:.

Whichever term is used, deflationary theories can be said to hold in common that "[t]he predicate 'true' is an expressive convenience, not the name of a property requiring deep analysis. Among the theoretical concerns of these views is to explain away those special cases where it does appear that the concept of truth has peculiar and interesting properties.

See, e. In addition to highlighting such formal aspects of the predicate "is true", some deflationists point out that the concept enables us to express things that might otherwise require infinitely long sentences. For example, one cannot express confidence in Michael's accuracy by asserting the endless sentence:. This assertion can also be succinctly expressed by saying: What Michael says is true.

Attributed to P. Strawson is the performative theory of truth which holds that to say "'Snow is white' is true" is to perform the speech act of signaling one's agreement with the claim that snow is white much like nodding one's head in agreement.

The idea that some statements are more actions than communicative statements is not as odd as it may seem. Consider, for example, that when the wedding couple say "I do" at the appropriate time in a wedding, they are performing the act of taking the other to be their lawful wedded spouse.

They are not describing themselves as taking the other, but actually doing so perhaps the most thorough analysis of such "illocutionary acts" is J. Strawson holds that a similar analysis is applicable to all speech acts, not just illocutionary ones: "To say a statement is true is not to make a statement about a statement, but rather to perform the act of agreeing with, accepting, or endorsing a statement.

When one says 'It's true that it's raining,' one asserts no more than 'It's raining. According to the redundancy theory of truth , asserting that a statement is true is completely equivalent to asserting the statement itself. Redundancy theorists infer from this premise that truth is a redundant concept; that is, it is merely a word that is traditionally used in conversation or writing, generally for emphasis, but not a word that actually equates to anything in reality. This theory is commonly attributed to Frank P.

Ramsey , who held that the use of words like fact and truth was nothing but a roundabout way of asserting a proposition, and that treating these words as separate problems in isolation from judgment was merely a "linguistic muddle".

A variant of redundancy theory is the disquotational theory which uses a modified form of Tarski 's schema : To say that '"P" is true' is to say that P. A version of this theory was defended by C. Williams in his book What is Truth? Yet another version of deflationism is the prosentential theory of truth, first developed by Dorothy Grover, Joseph Camp, and Nuel Belnap as an elaboration of Ramsey's claims.

They argue that sentences like "That's true", when said in response to "It's raining", are prosentences , expressions that merely repeat the content of other expressions. In the same way that it means the same as my dog in the sentence My dog was hungry, so I fed it , That's true is supposed to mean the same as It's raining —if you say the latter and I then say the former. These variations do not necessarily follow Ramsey in asserting that truth is not a property, but rather can be understood to say that, for instance, the assertion "P" may well involve a substantial truth, and the theorists in this case are minimizing only the redundancy or prosentence involved in the statement such as "that's true.

Deflationary principles do not apply to representations that are not analogous to sentences, and also do not apply to many other things that are commonly judged to be true or otherwise. Consider the analogy between the sentence "Snow is white" and the character named Snow White, both of which can be true in some sense.

To a minimalist, saying "Snow is white is true" is the same as saying "Snow is white," but to say "Snow White is true" is not the same as saying "Snow White. Philosophical skepticism is generally any questioning attitude or doubt towards one or more items of knowledge or belief which ascribe truth to their assertions and propositions.

Philosophical skepticism comes in various forms. Radical forms of skepticism deny that knowledge or rational belief is possible and urge us to suspend judgment regarding ascription of truth on many or all controversial matters. More moderate forms of skepticism claim only that nothing can be known with certainty, or that we can know little or nothing about the "big questions" in life, such as whether God exists or whether there is an afterlife. Religious skepticism is "doubt concerning basic religious principles such as immortality, providence, and revelation ".

Davidson's "Coherence Theory of Truth and Knowledge" (1999)

The coherence theory holds that truth consists in coherence amongst our beliefs. It can thus rule out radical scepticism and avoid the problems of the correspondence theory. Considerations about meaning and verification have also pointed philosophers in the same direction. But if it holds all truth to consist in coherence it is untenable: there must be some truths that do not, truths about what people believe. This causes problems for traditional coherence theories, and also for verificationists and anti-realists. The admission of a grounding class of truths that do not consist in coherence also raises the question why there should be such systematic agreement between these.

Someone might try to defend a coherence theory of truth without defending a coherence theory of knowledge, perhaps on the ground that the holder of a coherent set of beliefs might lack a reason to believe his beliefs coherent.
