A fact is a true datum about one or more aspects of a circumstance. [1] Standard reference works are often used to check facts. Scientific facts are verified by repeatable careful observation or measurement by experiments or other means.

Contents

For example, "This sentence contains words." accurately describes a linguistic fact, and "The sun is a star" accurately describes an astronomical fact. Further, "Abraham Lincoln was the 16th President of the United States" and "Abraham Lincoln was assassinated" both accurately describe historical facts. Generally speaking, facts are independent of belief and of knowledge and opinion.

Facts are different from inferences, theories, values, and objects. [2]

Etymology and usage

The word fact derives from the Latin factum. It was first used in English with the same meaning: "a thing done or performed" a meaning now obsolete. [3] The common usage of "something that has really occurred or is the case" dates from the mid-16th century. [3]

Barbara J. Shapiro wrote in her book A Culture of Fact how the concept of a fact evolved, starting within the English legal tradition of the 16th century. [4]

In 1870, Charles Sanders Peirce described in his book "The Fixation of Belief" four methods which people use to decide what they should believe: tenacity, method of authority, a priori and scientific method. [5]

The term fact also indicates a matter under discussion deemed to be true or correct, such as to emphasize a point or prove a disputed issue; (e.g., "... the fact of the matter is ..."). [6] [7]

Alternatively, fact may also indicate an allegation or stipulation of something that may or may not be a true fact, [8] (e.g., "the author's facts are not trustworthy"). This alternate usage, although contested by some, has a long history in standard English according to the American Heritage Dictionary of the English Language. [9] The Oxford English Dictionary dates this use to 1729.[ citation needed ]

Fact may also indicate findings derived through a process of evaluation, including review of testimony, direct observation, or otherwise; as distinguishable from matters of inference or speculation. [10] This use is reflected in the terms "fact-find" and "fact-finder" (e.g., "set up a fact-finding commission"). [11]

Facts may be checked by reason, experiment, personal experience, or may be argued from authority. Roger Bacon wrote "If in other sciences we should arrive at certainty without doubt and truth without error, it behooves us to place the foundations of knowledge in mathematics." [12]

In philosophy

In philosophy, the concept fact is considered in the branch of philosophy concerned with knowledge, called epistemology and ontology, which studies concepts such as existence, being, becoming, and reality. Questions of objectivity and truth are closely associated with questions of fact. A fact can be defined as something that is the case, in other words, a state of affairs. [13] [14]

Facts may be understood as information, which makes a true sentence true: "A fact is, traditionally, the worldly correlate of a true proposition, a state of affairs whose obtaining makes that proposition true." [15] Facts may also be understood as those things to which a true sentence refers. The statement "Jupiter is the largest planet in the solar system" is about the fact that Jupiter is the largest planet in the solar system. [16]

Correspondence and the slingshot argument

Pascal Engel's version of the correspondence theory of truth explains that what makes a sentence true is that it corresponds to a fact. [17] This theory presupposes the existence of an objective world.

The Slingshot argument claims to show that all true statements stand for the same thing, the truth value true. If this argument holds, and facts are taken to be what true statements stand for, then one arrives at the counter-intuitive conclusion that there is only one fact: the truth. [18]

Compound facts

Any non-trivial true statement about reality is necessarily an abstraction composed of a complex of objects and properties or relations."Facts possess internal structure, being complexes of objects and properties or relations" [15] For example, the fact described by the true statement "Paris is the capital city of France" implies that there is such a place as Paris, there is such a place as France, there are such things as capital cities, as well as that France has a government, that the government of France has the power to define its capital city, and that the French government has chosen Paris to be the capital, that there is such a thing as a place or a government, and so on. The verifiable accuracy of all of these assertions, if facts themselves, may coincide to create the fact, that Paris is the capital of France.

Difficulties arise, however, in attempting to identify the constituent parts of negative, modal, disjunctive, or moral facts. [19]

Fact–value distinction

Moral philosophers since David Hume have debated whether values are objective, and thus factual. In A Treatise of Human Nature Hume pointed out there is no obvious way for a series of statements about what ought to be the case to be derived from a series of statements of what is the case. This is called the is–ought distinction. Those who insist there is a logical gulf between facts and values, such that it is fallacious to attempt to derive values (e.g., "it is good to give food to hungry people") from facts (e.g., "people will die if they can't eat"), include G. E. Moore, who called attempting to do so the naturalistic fallacy.

Factual–counterfactual distinction

Factuality—what has occurred—can also be contrasted with counterfactuality: what might have occurred, but did not. A counterfactual conditional or subjunctive conditional is a conditional (or "if–then") statement indicating what would be the case if events had been other than they were. For example, "If Alexander had lived, his empire would have been greater than Rome." This contrasts with an indicative conditional, which indicates what is (in fact) the case if its antecedent is (in fact) true—for example, "If you drink this, it will make you well." Such sentences are important to modal logic, especially since the development of possible world semantics.[ citation needed ]

In mathematics

In mathematics, a fact is a statement (called a theorem) that can be proven by logical argument from certain axioms and definitions.[ citation needed ]

In science

The definition of a scientific fact is different from the definition of fact, as it implies knowledge. A scientific fact is the result of a repeatable careful observation or measurement by experimentation or other means, also called empirical evidence. These are central to building scientific theories. Various forms of observation and measurement lead to fundamental questions about the scientific method, and the scope and validity of scientific reasoning.

In the most basic sense, a scientific fact is an objective and verifiable observation, in contrast with a hypothesis or theory , which is intended to explain or interpret facts. [20]

Various scholars have offered significant refinements to this basic formulation. Philosophers and scientists are careful to distinguish between: 1) states of affairs in the external world and 2) assertions of fact that may be considered relevant in scientific analysis. The term is used in both senses in the philosophy of science. [21]

Scholars and clinical researchers in both the social and natural sciences have written about numerous questions and theories that arise in the attempt to clarify the fundamental nature of scientific fact. [20] Pertinent issues raised by this inquiry include:

Consistent with the idea of confirmation holism, some scholars assert "fact" to be necessarily "theory-laden" to some degree. Thomas Kuhn points out that knowing what facts to measure, and how to measure them, requires the use of other theories. For example, the age of fossils is based on radiometric dating, which is justified by reasoning that radioactive decay follows a Poisson process rather than a Bernoulli process. Similarly, Percy Williams Bridgman is credited with the methodological position known as operationalism, which asserts that all observations are not only influenced, but necessarily defined, by the means and assumptions used to measure them.[ citation needed ]

The scientific method

Apart from the fundamental inquiry into the nature of scientific fact, there remain the practical and social considerations of how fact is investigated, established, and substantiated through the proper application of the scientific method. [21] :181 ff Scientific facts are generally believed independent of the observer: no matter who performs a scientific experiment, all observers agree on the outcome. [22] In addition to these considerations, there are the social and institutional measures, such as peer review and accreditation, that are intended to promote factual accuracy among other interests in scientific study. [21]

In history

A common rhetorical cliché states, "History is written by the winners". This phrase suggests but does not examine the use of facts in the writing of history.[ citation needed ]

E. H. Carr in his 1961 volume What is History? argues that the inherent biases from the gathering of facts makes the objective truth of any historical perspective idealistic and impossible. Facts are, "like fish in the Ocean", of which we may only happen to catch a few, only an indication of what is below the surface. Even a dragnet cannot tell us for certain what it would be like to live below the Ocean's surface. Even if we do not discard any facts (or fish) presented, we will always miss the majority; the site of our fishing, the methods undertaken, the weather and even luck play a vital role in what we will catch. Additionally, the composition of history is inevitably made up by the compilation of many different biases of fact finding – all compounded over time. He concludes that for a historian to attempt a more objective method, one must accept that history can only aspire to a conversation of the present with the past – and that one's methods of fact gathering should be openly examined. The set of highlighted historical facts, and their interpretations, therefore changes over time, and reflect present consensuses.[ citation needed ]

In law

This section of the article emphasizes common law jurisprudence as primarily represented in Anglo-American–based legal tradition. Nevertheless, the principles described herein have analogous treatment in other legal systems such as civil law systems as well.

In most common law jurisdictions, the general concept and analysis of fact reflects fundamental principles of jurisprudence, and is supported by several well-established standards. [23] [24] Matters of fact have various formal definitions under common law jurisdictions.

These include:

A party (e.g., plaintiff) to a civil suit generally must clearly state the relevant allegations of fact that form the basis of a claim. The requisite level of precision and particularity of these allegations varies, depending on the rules of civil procedure and jurisdiction. Parties who face uncertainties regarding facts and circumstances attendant to their side in a dispute may sometimes invoke alternative pleading. [30] In this situation, a party may plead separate sets of facts that when considered together may be contradictory or mutually exclusive. This seemingly logically-inconsistent presentation of facts may be necessary as a safeguard against contingencies such as res judicata that would otherwise preclude presenting a claim or defense that depends on a particular interpretation of the underlying facts and ruling of the court. [31]

<span class="mw-page-title-main">Falsifiability</span> Property of a statement that can be logically contradicted

Falsifiability is a deductive standard of evaluation of scientific theories and hypotheses, introduced by the philosopher of science Karl Popper in his book The Logic of Scientific Discovery (1934). A theory or hypothesis is falsifiable if it can be logically contradicted by an empirical test.

Logical positivism, later called logical empiricism, and both of which together are also known as neopositivism, is a movement whose central thesis is the verification principle. This theory of knowledge asserts that only statements verifiable through direct observation or logical proof are meaningful in terms of conveying truth value, information or factual content. Starting in the late 1920s, groups of philosophers, scientists, and mathematicians formed the Berlin Circle and the Vienna Circle, which, in these two cities, would propound the ideas of logical positivism.

Truth or verity is the property of being in accord with fact or reality. In everyday language, truth is typically ascribed to things that aim to represent reality or otherwise correspond to it, such as beliefs, propositions, and declarative sentences.

A theory is a rational type of abstract thinking about a phenomenon, or the results of such thinking. The process of contemplative and rational thinking is often associated with such processes as observational study or research. Theories may be scientific, belong to a non-scientific discipline, or no discipline at all. Depending on the context, a theory's assertions might, for example, include generalized explanations of how nature works. The word has its roots in ancient Greek, but in modern use it has taken on several related meanings.

Philosophy of science is the branch of philosophy concerned with the foundations, methods, and implications of science. Amongst its central questions are the difference between science and non-science, the reliability of scientific theories, and the ultimate purpose and meaning of science as a human endeavour. Philosophy of science focuses on metaphysical, epistemic and semantic aspects of scientific practice, and overlaps with metaphysics, ontology, logic, and epistemology, for example, when it explores the relationship between science and the concept of truth. Philosophy of science is both a theoretical and empirical discipline, relying on philosophical theorising as well as meta-studies of scientific practice. Ethical issues such as bioethics and scientific misconduct are often considered ethics or science studies rather than the philosophy of science.

Causality is an influence by which one event, process, state, or object (acause) contributes to the production of another event, process, state, or object (an effect) where the cause is partly responsible for the effect, and the effect is partly dependent on the cause. In general, a process has many causes, which are also said to be causal factors for it, and all lie in its past. An effect can in turn be a cause of, or causal factor for, many other effects, which all lie in its future. Some writers have held that causality is metaphysically prior to notions of time and space.

<span class="mw-page-title-main">Thought experiment</span> Hypothetical situation

A thought experiment is a hypothetical situation in which a hypothesis, theory, or principle is laid out for the purpose of thinking through its consequences. The concept is also referred to as a Gedankenexperiment within the work of Ernst Mach and includes thoughts about what may have occurred if a different course of action were taken as opposed to what did in fact occur. The importance of this ability is that it allows us to imagine what may occur in the future, as well as the implication of alternate courses of action.

In mathematics and logic, a vacuous truth is a conditional or universal statement that is true because the antecedent cannot be satisfied. It is sometimes said that a statement is vacuously true because it does not really say anything. For example, the statement "all cell phones in the room are turned off" will be true when no cell phones are present in the room. In this case, the statement "all cell phones in the room are turned on" would also be vacuously true, as would the conjunction of the two: "all cell phones in the room are turned on and turned off", which would otherwise be incoherent and false.

Empirical evidence for a proposition is evidence, i.e. what supports or counters this proposition, that is constituted by or accessible to sense experience or experimental procedure. Empirical evidence is of central importance to the sciences and plays a role in various other fields, like epistemology and law.

In metaphysics, phenomenalism is the view that physical objects cannot justifiably be said to exist in themselves, but only as perceptual phenomena or sensory stimuli situated in time and in space. In particular, some forms of phenomenalism reduce all talk about physical objects in the external world to talk about bundles of sense data.

David Kellogg Lewis was an American philosopher. Lewis taught briefly at UCLA and then at Princeton University from 1970 until his death. He is closely associated with Australia, whose philosophical community he visited almost annually for more than 30 years.

Counterfactual conditionals are conditional sentences which discuss what would have been true under different circumstances, e.g. "If Peter believed in ghosts, he would be afraid to be here." Counterfactuals are contrasted with indicatives, which are generally restricted to discussing open possibilities. Counterfactuals are characterized grammatically by their use of fake tense morphology, which some languages use in combination with other kinds of morphology including aspect and mood.

Conditional sentences are natural language sentences that express that one thing is contingent on something else, e.g. "If it rains, the picnic will be cancelled." They are so called because the impact of the main clause of the sentence is conditional on the dependent clause. A full conditional thus contains two clauses: a dependent clause called the antecedent, which expresses the condition, and a main clause called the consequent expressing the result.

A pragmatic theory of truth is a theory of truth within the philosophies of pragmatism and pragmaticism. Pragmatic theories of truth were first posited by Charles Sanders Peirce, William James, and John Dewey. The common features of these theories are a reliance on the pragmatic maxim as a means of clarifying the meanings of difficult concepts such as truth; and an emphasis on the fact that belief, certainty, knowledge, or truth is the result of an inquiry.

The deductive-nomological model of scientific explanation, also known as Hempel's model, the Hempel–Oppenheim model, the Popper–Hempel model, or the covering law model, is a formal view of scientifically answering questions asking, "Why...?". The DN model poses scientific explanation as a deductive structure, one where truth of its premises entails truth of its conclusion, hinged on accurate prediction or postdiction of the phenomenon to be explained.

In philosophy—more specifically, in its sub-fields semantics, semiotics, philosophy of language, metaphysics, and metasemantics—meaning "is a relationship between two sorts of things: signs and the kinds of things they intend, express, or signify".

Ramsey sentences are formal logical reconstructions of theoretical propositions attempting to draw a line between science and metaphysics. A Ramsey sentence aims at rendering propositions containing non-observable theoretical terms clear by substituting them with observational terms.

Evidence for a proposition is what supports the proposition. It is usually understood as an indication that the supported proposition is true. What role evidence plays and how it is conceived varies from field to field.

<span class="mw-page-title-main">Hypothesis</span> Proposed explanation for an observation, phenomenon, or scientific problem

A hypothesis is a proposed explanation for a phenomenon. For a hypothesis to be a scientific hypothesis, the scientific method requires that one can test it. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories. Even though the words "hypothesis" and "theory" are often used interchangeably, a scientific hypothesis is not the same as a scientific theory. A working hypothesis is a provisionally accepted hypothesis proposed for further research in a process beginning with an educated guess or thought.
