Truth

Truth is conformity to reality or fact. It contrasts with falsity or misrepresentation that fails to align with the world. Truth is typically treated as a property of entities such as sentences, propositions, or beliefs that describe things as they are. It is closely related to truthfulness, a virtue associated with honesty, and to truthlikeness, a characteristic of theories that approximate the truth. Various theories of the nature of truth have been proposed, but its precise definition remains contested. The correspondence theory holds that a statement is true if it corresponds to facts. According to the coherence theory, truth consists in logical consistency and mutual support among beliefs. Pragmatists understand truth in terms of practical consequences and epistemic practices, claiming that truth is what works or what would withstand the test of unlimited inquiry. The semantic theory analyzes the truth conditions of sentences in an object language from the perspective of a metalanguage. Deflationary theories argue that truth has no significant intrinsic nature, holding that the linguistic role of truth-related expressions exhausts the concept of truth. Pluralists assert that the definition of truth varies with the domain of analysis, while relativists maintain that the same statement can be true in one perspective and false in another. Theories of truth are challenged by logical paradoxes, such as the liar paradox. There are also discussions about the existence of additional truth values besides true and false and about the possibility of truth value gaps—statements that have no truth value. Philosophers distinguish types of truth by domain, content, and epistemic access, including a priori, necessary, moral, aesthetic, religious, and scientific truths. Truth plays a central role in the sciences as a goal of inquiry. The empirical sciences seek truth through observation and experimentation, whereas the formal sciences rely on deductive reasoning from fundamental principles. Many religious traditions regard truth as a virtue and ground it in a divine source. Truth also acts as a guiding norm in the fields of ethics, law, and journalism. Discussions of truth arose in antiquity in Hindu, Jain, Buddhist, and Greek thought. In the medieval period, Christian and Islamic philosophers explored the relation between truth and God. Discussions in the modern and contemporary periods have addressed diverse topics, such as the nature of truth and its relation to thought, language, and reality.

Definition Truth is conformity to facts or accordance with reality. It is often understood as a property of statements or beliefs that present the world as it is, or as a relation between language or thought and how things actually are. However, its precise definition is disputed, with different theories focusing on elements such as correspondence, coherence, or practical usefulness. In a slightly different sense, the term can also refer to genuineness, as in "a true friend" or "true gold", spiritual teachings, like "the truth of the scriptures", or facts themselves, such as "in truth, the product was defective." Truth contrasts with falsehood or falsity, which encompasses misrepresentations that do not meet this standard and fail to align with reality. The negation of a true statement is a falsehood. Truth plays a central role in many human endeavors. It acts as a goal of inquiry when deciding what to believe and as a standard to which right conduct should conform by being responsive to how things actually are. People refer to truth to indicate reliable information, mark scientific findings well supported by evidence, distinguish accurate legal testimony from misrepresentation, and emphasize honesty and sincerity in personal life. Truth is typically regarded as a positive value, either because of its beneficial consequences or as an intrinsic good pursued for its own sake. The word truth comes from the Old English trēowth, meaning 'fidelity'. It entered Modern English via the Middle English term trewthe.

Basic concepts

Truthbearers

Truth is commonly treated as a feature of truthbearers—entities that can be true or false. Philosophers discuss which entities serve as truthbearers, including sentences, propositions, and beliefs. Sentences are concrete linguistic entities composed of strings of words, like "It's raining in Nairobi." Their public nature and clear structure can aid philosophical analysis of truth-related phenomena. However, it is not always possible to establish a straightforward relation between a sentence and its truth value since its meaning can be context-dependent and may also be influenced by ambiguous terms. As a result, a sentence may be true under one interpretation and false under another. Another difficulty is that sentences belong to specific languages, with the danger of limiting philosophical analysis to language-specific features rather than articulating universal principles. Propositions are typically understood as abstract entities that serve as the meanings of declarative sentences, mitigating the difficulties of context dependence, ambiguity, and language specificity. However, their abstract nature can make philosophical discussions less tangible, and there is disagreement about the existence of abstract objects. Beliefs and related mental states are concrete psychological entities, taking the form of subjective attitudes about what is the case. They establish a direct link between truth and cognition but are difficult to study because of their private nature. Monists argue that there is only a single kind of truthbearer, while pluralists accept different kinds. Some identify one kind as primary, explaining the truth values of secondary truthbearers in terms of the primary one. For example, one proposal reduces the truth of beliefs to sentences since sentences can be used to express beliefs.
