Certainty
Certainty (also known as epistemic certainty or objective certainty) is the epistemic property of beliefs which a person has no rational grounds for doubting. One standard way of defining epistemic certainty is that a belief is certain if and only if the person holding that belief could not be mistaken in holding that belief. Other common definitions of certainty involve the indubitable nature of such beliefs or define certainty as a property of those beliefs with the greatest possible justification. Certainty is closely related to knowledge, although contemporary philosophers tend to treat knowledge as having lower requirements than certainty. Importantly, epistemic certainty is not the same thing as psychological certainty (also known as subjective certainty or certitude), which describes the highest degree to which a person could be convinced that something is true. While a person may be completely convinced that a particular belief is true, and might even be psychologicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
On Certainty
''On Certainty'' (german: Über Gewissheit, original spelling ) is a philosophical book composed from notes written by Ludwig Wittgenstein over four separate periods in the eighteen months before his death on 29 April 1951. He left his initial notes at the home of Elizabeth Anscombe, who linked them by theme with later passages in Wittgenstein's personal notebooks and (with G. H. von Wright), compiled them into a German/English parallel text book published in 1969. The translators were Denis Paul and Anscombe herself. (The editors also numbered and grouped the 676 passages; citations to the work are standardly given as OC1..OC676 rather than by page number.) The book's concerns are largely epistemological, a recurrent theme being that there are some things which must be exempt from doubt in order for human practices to be possible, including the activity of raising doubts: "A doubt that doubted everything would not be a doubt" (OC450). The book takes as its starting point the 'her ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ludwig Wittgenstein
Ludwig Josef Johann Wittgenstein ( ; ; 26 April 1889 – 29 April 1951) was an Austrian-British philosopher who worked primarily in logic, the philosophy of mathematics, the philosophy of mind, and the philosophy of language. He is considered by some to be the greatest philosopher of the 20th century. From 1929 to 1947, Wittgenstein taught at the University of Cambridge. In spite of his position, during his entire life only one book of his philosophy was published, the 75-page ''Logisch-Philosophische Abhandlung'' (''Logical-Philosophical Treatise'', 1921), which appeared, together with an English translation, in 1922 under the Latin title ''Tractatus Logico-Philosophicus''. His only other published works were an article, "Some Remarks on Logical Form" (1929); a book review; and a children's dictionary. His voluminous manuscripts were edited and published posthumously. The first and best-known of this posthumous series is the 1953 book ''Philosophical Investigations''. A su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philosophical Skepticism
Philosophical skepticism ( UK spelling: scepticism; from Greek σκέψις ''skepsis'', "inquiry") 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 criti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Infallibilism
Infallibilism is the epistemological view that propositional knowledge is incompatible with the possibility of being wrong. Definition In philosophy, infallibilism (sometimes called "epistemic infallibilism") is the view that knowing the truth of a proposition is incompatible with there being any possibility that the proposition could be false. This is typically understood as indicating that for a belief to count as knowledge, one's evidence or justification must provide one with such strong grounds that the belief ''must'' be true, or equivalently, that it is completely impossible for it to be false. The infallibility of such a belief may also mean that it cannot even be doubted. Importantly, infallibilism should not be confused with the universally accepted view that a proposition ''P'' must be true in order for someone to know that ''P''. Instead, the infallibilist holds that a person who knows ''P'' could not have all of the same evidence (or justification) that one currentl ...

Fallibilism
Originally, fallibilism (from Medieval Latin: ''fallibilis'', "liable to err") is the philosophical principle that Proposition, propositions can be accepted even though they cannot be conclusively proven or Justification (epistemology), justified,Haack, Susan (1979)"Fallibilism and Necessity" ''Synthese'', Vol. 41, No. 1, pp. 37–63. or that neither knowledge nor belief is Certainty, certain.Hetherington, Stephen"Fallibilism" ''Internet Encyclopedia of Philosophy''. 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.

Uncertainty
Uncertainty refers to epistemic situations involving imperfect or unknown information. It applies to predictions of future events, to physical measurements that are already made, or to the unknown. Uncertainty arises in partially observable or stochastic environments, as well as due to ignorance, indolence, or both. It arises in any number of fields, including insurance, philosophy, physics, statistics, economics, finance, medicine, psychology, sociology, engineering, metrology, meteorology, ecology and information science. Concepts Although the terms are used in various ways among the general public, many specialists in decision theory, statistics and other quantitative fields have defined uncertainty, risk, and their measurement as: Uncertainty The lack of certainty, a state of limited knowledge where it is impossible to exactly describe the existing state, a future outcome, or more than one possible outcome. ;Measurement of uncertainty: A set of possible states or outc ...

Epistemic
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. Epistemologists study the nature, origin, and scope of knowledge, epistemic justification, the rationality of belief, and various related issues. Debates in epistemology are generally clustered around four core areas: # The philosophical analysis of the nature of knowledge and the conditions required for a belief to constitute knowledge, such as truth and justification # Potential sources of knowledge and justified belief, such as perception, reason, memory, and testimony # The structure of a body of knowledge or justified belief, including whether all justified beliefs must be derived from justified foundational beliefs or whether justification requires only a coherent set of beliefs # Philosophical skepticism, which questions the possibili ...

Anti-foundationalism
Anti-foundationalism (also called nonfoundationalism) is any philosophy which rejects a foundationalist approach. An anti-foundationalist is one who does not believe that there is some fundamental belief or principle which is the basic ground or foundation of inquiry and knowledge. Anti-essentialism Anti-foundationalists use logical or historical or genealogical attacks on foundational concepts (see especially Nietzsche and Foucault), often coupled with alternative methods for justifying and forwarding intellectual inquiry, such as the pragmatic subordination of knowledge to practical action. Foucault dismissed the search for a return to origins as Platonic essentialism, preferring to stress the contingent nature of human practices. Anti-foundationalists oppose metaphysical methods. Moral and ethical anti-foundationalists are often criticized for moral relativism, but anti-foundationalists often dispute this charge, offering alternative methods of moral thought that they claim ...

Dogma
Dogma is a belief or set of beliefs that is accepted by the members of a group without being questioned or doubted. It may be in the form of an official system of principles or doctrines of a religion, such as Roman Catholicism, Judaism, Islam or Protestantism, as well as the Philosophical theory, positions of a philosopher or of a Philosophical movement, philosophical school such as positivism, postmodernism, egalitarianism, and dark enlightenment. It may also be found in political belief-systems, such as Marxism, communism, capitalism, progressivism, liberalism, conservatism, and fascism. In the pejorative sense, dogma refers to enforced decisions, such as those of aggressive political interests or authorities. More generally, it is applied to some strong belief which its adherents are not willing to discuss rationally. This attitude is named as a dogmatic one, or as dogmatism; and is often used to refer to matters related to religion, but is not limited to theistic attitudes ...

Context (language Use)
In semiotics, linguistics, sociology and anthropology, context refers to those objects or entities which surround a ''focal event'', in these disciplines typically a communicative event, of some kind. Context is "a frame that surrounds the event and provides resources for its appropriate interpretation". It is thus a relative concept, only definable with respect to some focal event within a frame, not independently of that frame. In linguistics In the 19th century, it was debated whether the most fundamental principle in language was contextuality or compositionality, and compositionality was usually preferred.Janssen, T. M. (2012) Compositionality: Its historic context', in M. Werning, W. Hinzen, & E. Machery (Eds.), The Oxford handbook of compositionality', pp. 19-46, Oxford University Press. Verbal context refers to the text or speech surrounding an expression (word, sentence, or speech act). Verbal context influences the way an expression is understood; hence the norm of no ...
