Basic Definition Of “Truth” In its simplest form, truth can be understood as the opposite of falsehood or deception. It is the quality of being in accordance with facts, reality, or actuality. Truth is often associated with honesty, integrity, and reliability, as it represents an accurate representation of the world around us. Historical Evolution.

truth, in metaphysics and the philosophy of language, the property of sentences, assertions, beliefs, thoughts, or propositions that are said, in ordinary discourse, to agree with the facts or to state what is the case.
Truth is the aim of belief; falsity is a fault. People need the truth about the world in order to thrive. Truth is important. Believing what is not true is apt to spoil people’s plans and may even cost them their lives. Telling what is not true may result in legal and social penalties. Conversely, a dedicated pursuit of truth characterizes the good scientist, the good historian, and the good detective. So what is truth, that it should have such gravity and such a central place in people’s lives?
The classic suggestion comes from Aristotle (384–322 bce): “To say of what is that it is, or of what is not that it is not, is true.” In other words, the world provides “what is” or “what is not,” and the true saying or thought corresponds to the fact so provided. This idea appeals to common sense and is the germ of what is called the correspondence theory of truth. As it stands, however, it is little more than a platitude and far less than a theory. Indeed, it may amount to merely a wordy paraphrase, whereby, instead of saying “that’s true” of some assertion, one says “that corresponds with the facts.” Only if the notions of fact and correspondence can be further developed will it be possible to understand truth in these terms.
Unfortunately, many philosophers doubt whether an acceptable explanation of facts and correspondence can be given. Facts, as they point out, are strange entities. It is tempting to think of them as structures or arrangements of things in the world. However, as the Austrian-born philosopher Ludwig Wittgenstein observed, structures have spatial locations, but facts do not. The Eiffel Tower can be moved from Paris to Rome, but the fact that the Eiffel Tower is in Paris cannot be moved anywhere. Furthermore, critics urge, the very idea of what the facts are in a given case is nothing apart from people’s sincere beliefs about the case, which means those beliefs that people take to be true. Thus, there is no enterprise of first forming a belief or theory about some matter and then in some new process stepping outside the belief or theory to assess whether it corresponds with the facts. There are, indeed, processes of checking and verifying beliefs, but they work by bringing up further beliefs and perceptions and assessing the original in light of those. In actual investigations, what tells people what to believe is not the world or the facts but how they interpret the world or select and conceptualize the facts.
Starting in the mid-19th century, this line of criticism led some philosophers to think that they should concentrate on larger theories, rather than sentences or assertions taken one at a time. Truth, on this view, must be a feature of the overall body of belief considered as a system of logically interrelated components—what is called the “web of belief.” It might be, for example, an entire physical theory that earns its keep by making predictions or enabling people to control things or by simplifying and unifying otherwise disconnected phenomena. An individual belief in such a system is true if it sufficiently coheres with, or makes rational sense within, enough other beliefs; alternatively, a belief system is true if it is sufficiently internally coherent. Such were the views of the British idealists, including F.H. Bradley and H.H. Joachim, who, like all idealists, rejected the existence of mind-independent facts against which the truth of beliefs could be determined (see also realism: realism and truth).
Yet coherentism too seems inadequate, since it suggests that human beings are trapped in the sealed compartment of their own beliefs, unable to know anything of the world beyond. Moreover, as the English philosopher and logician Bertrand Russell pointed out, nothing seems to prevent there being many equally coherent but incompatible belief systems. Yet at best only one of them can be true.

Some theorists have suggested that belief systems can be compared in pragmatic or utilitarian terms. According to this idea, even if many different systems can be internally coherent, it is likely that some will be much more useful than others. Thus, one can expect that, in a process akin to Darwinian natural selection, the more useful systems will survive while the others gradually go extinct. The replacement of Newtonian mechanics by relativity theory is an example of this process. It was in this spirit that the 19th-century American pragmatist philosopher Charles Sanders Peirce said:
The opinion which is fated to be ultimately agreed to by all who investigate, is what we mean by the truth, and the object represented in this opinion is the real.
The rise of formal logic (the abstract study of assertions and deductive arguments) and the growth of interest in formal systems (formal or mathematical languages) among many Anglo-American philosophers in the early 20th century led to new attempts to define truth in logically or scientifically acceptable terms. It also led to a renewed respect for the ancient liar paradox (attributed to the ancient Greek philosopher Epimenides), in which a sentence says of itself that it is false, thereby apparently being true if it is false and false if it is true. Logicians set themselves the task of developing systems of mathematical reasoning that would be free of the kinds of self-reference that give rise to paradoxes such as that of the liar. However, this proved difficult to do without at the same time making some legitimate proof procedures impossible. There is good self-reference (“All sentences, including this, are of finite length”) and bad self-reference (“This sentence is false”) but no generally agreed-upon principle for distinguishing them.
These efforts culminated in the work of the Polish-born logician Alfred Tarski, who in the 1930s showed how to construct a definition of truth for a formal or mathematical language by means of a theory that would assign truth conditions (the conditions in which a given sentence is true) to each sentence in the language without making use of any semantic terms, notably including truth, in that language. Truth conditions were identified by means of “T-sentences.” For example, the English-language T-sentence for the German sentence Schnee ist weiss is: “Schnee ist weiss” is true if and only if snow is white. A T-sentence says of some sentence (S) in the object language (the language for which truth is being defined) that S is true if and only if…, where the ellipsis is replaced by a translation of S into the language used to construct the theory (the metalanguage). Since no metalanguage translation of any S (in this case, snow is white) will contain the term true, Tarski could claim that each T-sentence provides a “partial definition” of truth for the object language and that their sum total provides the complete definition.
