Radical skepticism

Last updated

Radical skepticism (or radical scepticism in British English) is the philosophical position that knowledge is most likely impossible. [1] Radical skeptics hold that doubt exists as to the veracity of every belief and that certainty is therefore never justified. To determine the extent to which it is possible to respond to radical skeptical challenges is the task of epistemology or "the theory of knowledge". [2]

Epistemology, or the theory of knowledge, is the branch of philosophy concerned with knowledge. Epistemology is considered a major subfield of philosophy, along with other major subfields such as ethics, logic, and metaphysics.

In metaphilosophy and ethics, metaethics is the study of the nature, scope, and meaning of moral judgment. It is one of the three branches of ethics generally studied by philosophers, the others being normative ethics and applied ethics.

<span class="mw-page-title-main">Nihilism</span> Philosophy antithetical to concepts of meaningfulness

Nihilism is a philosophy, or family of views within philosophy, that rejects generally accepted or fundamental aspects of human existence, such as knowledge, morality, or meaning. The term was popularized by Ivan Turgenev, and more specifically by his character Bazarov in the novel Fathers and Sons.

Skepticism, also spelled scepticism, is a questioning attitude or doubt toward knowledge claims that are seen as mere belief or dogma. For example, if a person is skeptical about claims made by their government about an ongoing war then the person doubts that these claims are accurate. In such cases, skeptics normally recommend not disbelief but suspension of belief, i.e. maintaining a neutral attitude that neither affirms nor denies the claim. This attitude is often motivated by the impression that the available evidence is insufficient to support the claim. Formally, skepticism is a topic of interest in philosophy, particularly epistemology. More informally, skepticism as an expression of questioning or doubt can be applied to any topic, such as politics, religion, or pseudoscience. It is often applied within restricted domains, such as morality, atheism, or the supernatural. Some theorists distinguish "good" or moderate skepticism, which seeks strong evidence before accepting a position, from "bad" or radical skepticism, which wants to suspend judgment indefinitely.

Justification is the property of belief that qualifies it as knowledge rather than mere opinion. Epistemology is the study of reasons that someone holds a rationally admissible belief. Epistemologists are concerned with various epistemic features of belief, which include the ideas of warrant, knowledge, rationality, and probability, among others.

Philosophical skepticism is a family of philosophical views that question the possibility of knowledge. It differs from other forms of skepticism in that it even rejects very plausible knowledge claims that belong to basic common sense. Philosophical skeptics are often classified into two general categories: Those who deny all possibility of knowledge, and those who advocate for the suspension of judgment due to the inadequacy of evidence. This distinction is modeled after the differences between the Academic skeptics and the Pyrrhonian skeptics in ancient Greek philosophy. In the latter sense, skepticism is understood as a way of life that helps the practitioner achieve inner peace. Some types of philosophical skepticism reject all forms of knowledge while others limit this rejection to certain fields, for example, to knowledge about moral doctrines or about the external world. Some theorists criticize philosophical skepticism based on the claim that it is a self-refuting idea since its proponents seem to claim to know that there is no knowledge. Other objections focus on its implausibility and distance from regular life.

<span class="mw-page-title-main">Knowledge</span> Awareness of facts or being competent

Knowledge is a form of awareness or familiarity. It is often understood as awareness of facts or as practical skills, and may also mean familiarity with objects or situations. Knowledge of facts, also called propositional knowledge, is often defined as true belief that is distinct from opinion or guesswork by virtue of justification. While there is wide agreement among philosophers that propositional knowledge is a form of true belief, many controversies in philosophy focus on justification. This includes question like whether justification is needed at all, how to understand it, and whether something else besides it is needed. These controversies intensified due to a series of thought experiments by Edmund Gettier and have provoked various alternative definitions. Some of them deny that justification is necessary and suggest alternative criteria. Others accept that justification is an essential aspect and formulate additional requirements.

Moral nihilism is the meta-ethical view that nothing is morally right or morally wrong.

Contextualism, also known as epistemic contextualism, is a family of views in philosophy which emphasize the context in which an action, utterance, or expression occurs. Proponents of contextualism argue that, in some important respect, the action, utterance, or expression can only be understood relative to that context. Contextualist views hold that philosophically controversial concepts, such as "meaning P", "knowing that P", "having a reason to A", and possibly even "being true" or "being right" only have meaning relative to a specified context. Other philosophers contend that context-dependence leads to complete relativism.

Naturalized epistemology is a collection of philosophic views concerned with the theory of knowledge that emphasize the role of natural scientific methods. This shared emphasis on scientific methods of studying knowledge shifts focus to the empirical processes of knowledge acquisition and away from many traditional philosophical questions. There are noteworthy distinctions within naturalized epistemology. Replacement naturalism maintains that traditional epistemology should be abandoned and replaced with the methodologies of the natural sciences. The general thesis of cooperative naturalism is that traditional epistemology can benefit in its inquiry by using the knowledge we have gained from the cognitive sciences. Substantive naturalism focuses on an asserted equality of facts of knowledge and natural facts.

The Russian nihilist movement was a philosophical, cultural, and revolutionary movement in the Russian Empire during the late 19th and early 20th centuries, from which the broader philosophy of nihilism originated. In Russian, the word nigilizm came to represent the movement's unremitting attacks on morality, religion, and traditional society. Even as it was yet unnamed, the movement arose from a generation of young radicals disillusioned with the social reformers of the past, and from a growing divide between the old aristocratic intellectuals and the new radical intelligentsia.

Philosophy is the study of general and fundamental problems concerning matters such as existence, knowledge, values, reason, mind, and language. It is distinguished from other ways of addressing fundamental questions by being critical and generally systematic and by its reliance on rational argument. It involves logical analysis of language and clarification of the meaning of words and concepts.

<span class="mw-page-title-main">Fallibilism</span> Philosophical principle

Originally, fallibilism is the philosophical principle that propositions can be accepted even though they cannot be conclusively proven or justified, or that neither knowledge nor belief is certain. The term was coined in the late nineteenth century by the American philosopher Charles Sanders Peirce, as a response to foundationalism. Theorists, following Austrian-British philosopher Karl Popper, may also refer to fallibilism as the notion that knowledge might turn out to be false. Furthermore, fallibilism is said to imply corrigibilism, the principle that propositions are open to revision. Fallibilism is often juxtaposed with infallibilism.

Metaepistemology is the branch of epistemology and metaphilosophy that studies the underlying assumptions made in debates in epistemology, including those concerning the existence and authority of epistemic facts and reasons, the nature and aim of epistemology, and the methodology of epistemology.

Alethiology literally means the study of truth, but can more accurately be translated as the study of the nature of truth.

Epistemology or theory of knowledge is the branch of philosophy concerned with the nature and scope (limitations) of knowledge. It addresses the questions "What is knowledge?", "How is knowledge acquired?", "What do people know?", "How do we know what we know?", and "Why do we know what we know?". Much of the debate in this field has focused on analyzing the nature of knowledge and how it relates to similar notions such as truth, belief, and justification. It also deals with the means of production of knowledge, as well as skepticism about different knowledge claims.

<span class="mw-page-title-main">Anti-nihilistic novel</span> Form of novel from late 19th-century Russian literature

An anti-nihilistic novel is a form of novel from late 19th-century Russian literature, that came as a reaction to the disillusioned attitudes of the Russian nihilist movement and revolutionary socialism of the 1860s and 1870s. The genre was influential in shaping subsequent ideas on nihilism as a philosophy and cultural phenomenon. Its name derives from the historical usage of the word nihilism as broadly applied to revolutionary movements within the Russian Empire at the time.

<i>Academica</i> (Cicero)

The Academica is work in a fragmentary state written by the Academic Skeptic philosopher, Cicero, published in two editions. The first edition is referred to as the Academica Priora. It was released in May 45 BCE and comprised two books, known as the Catulus and the Lucullus. The Catulus has been lost. Cicero subsequently extensively revised and expanded the work, releasing a second edition comprising four books. Except for part of Book 1 and 36 fragments, all of the second edition has been lost. The second edition is referred to as Academica Posteriora or Academici Libri or Varro.
