Moore's Paradox
Moore's paradox concerns the apparent absurdity involved in asserting a first-person present-tense sentence such as "It is raining, but I do not believe that it is raining" or "It is raining, but I believe that it is not raining." The first author to note this apparent absurdity was G. E. Moore. These 'Moorean' sentences, as they have become known, are paradoxical in that while they appear absurd, they nevertheless # Can be true; # Are (logically) consistent; and # Are not (obviously) contradictions. The term 'Moore's paradox' is attributed to Ludwig Wittgenstein, who considered the paradox Moore's most important contribution to philosophy. Wittgenstein wrote about the paradox extensively in his later writings, which brought Moore's paradox the attention it would not have otherwise received. Moore's paradox has been connected to many other well-known logical paradoxes, including, though not limited to, the liar paradox, the knower paradox, the unexpected hanging paradox, and the ...

Contradiction
In traditional logic, a contradiction occurs when a proposition conflicts either with itself or established fact. It is often used as a tool to detect disingenuous beliefs and bias. Illustrating a general tendency in applied logic, Aristotle's law of noncontradiction states that "It is impossible that the same thing can at the same time both belong and not belong to the same object and in the same respect." In modern formal logic and type theory, the term is mainly used instead for a ''single'' proposition, often denoted by the falsum symbol \bot; a proposition is a contradiction if false can be derived from it, using the rules of the logic. It is a proposition that is unconditionally false (i.e., a self-contradictory proposition). This can be generalized to a collection of propositions, which is then said to "contain" a contradiction. History By creation of a paradox, Plato's '' Euthydemus'' dialogue demonstrates the need for the notion of ''contradiction''. In the ensuing ...

Self-deception
Self-deception is a process of denying or rationalizing away the relevance, significance, or importance of opposing evidence and logical argument. Self-deception involves convincing oneself of a truth (or lack of truth) so that one does not reveal any self-knowledge of the deception. Brief history While Freudian analysis of the conscious and the unconscious minds dominated the field, psychological scientists in the 1970s became curious about how those two seemingly separate worlds could work together. The lack of mechanistic models available to this line of research, led to the debate being unresolved. Later, the focus has been shifted to vision-related research in social psychology. Theorization Analysis The traditional paradigm of self-deception is modeled after ''interpersonal'' deception, where ''A'' intentionally gets ''B'' to believe some proposition ''p'', all the while knowing or believing truly ¬''p'' (not ''p''). Such deception is intentional and requires the decei ...

Doubt
Doubt is a mental state in which the mind remains suspended between two or more contradictory propositions, unable to be certain of any of them. Doubt on an emotional level is indecision between belief and disbelief. It may involve uncertainty, distrust or lack of conviction on certain facts, actions, motives, or decisions. Doubt can result in delaying or rejecting relevant action out of concern for mistakes or missed opportunities. Psychology Partial or intermittent negative reinforcement can create an effective climate of fear and doubt. Philosophy Descartes employed Cartesian doubt as a pre-eminent methodological tool in his fundamental philosophical investigations. Branches of philosophy like logic devote much effort to distinguish the dubious, the probable and the certain. Much of illogic rests on dubious assumptions, dubious data or dubious conclusions, with rhetoric, whitewashing, and deception playing their accustomed roles. Theology Doubt as a path towards (deep ...

Doublethink
Doublethink is a process of indoctrination in which subjects are expected to simultaneously accept two conflicting beliefs as truth, often at odds with their own memory or sense of reality. Doublethink is related to, but differs from, hypocrisy. George Orwell coined the term ''doublethink'' (as part of the fictional language of Newspeak) in his 1949 dystopian novel ''Nineteen Eighty-Four''.Orwell, George. 1949. ''Nineteen Eighty-Four''. London: Martin Secker & Warburg Ltd. In the novel, its origins within the citizenry is unclear; while it could be partly a product of Big Brother's formal brainwashing programs,Such as, for example, the seemingly formal brainwashing program that broke Winston Smith. the novel explicitly shows people learning doublethink and Newspeak due to peer pressure and a desire to "fit in," or gain status within the Party—to be seen as a loyal Party Member. In the novel, for someone to even recognize—let alone mention—any contradiction within the conte ...

Consistency
In classical deductive logic, a consistent theory is one that does not lead to a logical contradiction. The lack of contradiction can be defined in either semantic or syntactic terms. The semantic definition states that a theory is consistent if it has a model, i.e., there exists an interpretation under which all formulas in the theory are true. This is the sense used in traditional Aristotelian logic, although in contemporary mathematical logic the term ''satisfiable'' is used instead. The syntactic definition states a theory T is consistent if there is no formula \varphi such that both \varphi and its negation \lnot\varphi are elements of the set of consequences of T. Let A be a set of closed sentences (informally "axioms") and \langle A\rangle the set of closed sentences provable from A under some (specified, possibly implicitly) formal deductive system. The set of axioms A is consistent when \varphi, \lnot \varphi \in \langle A \rangle for no formula \varphi. If there e ...

Belief
A belief is an attitude that something is the case, or that some proposition is true. In epistemology, philosophers use the term "belief" to refer to attitudes about the world which can be either true or false. To believe something is to take it to be true; for instance, to believe that snow is white is comparable to accepting the truth of the proposition "snow is white". However, holding a belief does not require active introspection. For example, few carefully consider whether or not the sun will rise tomorrow, simply assuming that it will. Moreover, beliefs need not be ''occurrent'' (e.g. a person actively thinking "snow is white"), but can instead be ''dispositional'' (e.g. a person who if asked about the color of snow would assert "snow is white"). There are various different ways that contemporary philosophers have tried to describe beliefs, including as representations of ways that the world could be (Jerry Fodor), as dispositions to act as if certain things are true (Rod ...

Self-knowledge (psychology)
Self-knowledge is a term used in psychology to describe the information that an individual draws upon when finding an answer to the question "What am I like?". While seeking to develop the answer to this question, self-knowledge requires ongoing self-awareness and self-consciousness (which is not to be confused with consciousness). Young infants and chimpanzees display some of the traits of self-awareness and agency/contingency, yet they are not considered as also having self-consciousness. At some greater level of cognition, however, a self-conscious component emerges in addition to an increased self-awareness component, and then it becomes possible to ask "What am I like?", and to answer with self-knowledge, though self-knowledge has limits, as introspection has been said to be limited and complex. Self-knowledge is a component of the self or, more accurately, the self-concept. It is the knowledge of oneself and one's properties and the ''desire'' to seek such knowledge that g ...

Rational Belief
Rationality is the quality of being guided by or based on reasons. In this regard, a person acts rationally if they have a good reason for what they do or a belief is rational if it is based on strong evidence. This quality can apply to an ability, as in rational animal, to a psychological process, like reasoning, to mental states, such as beliefs and intentions, or to persons who possess these other forms of rationality. A thing that lacks rationality is either ''arational'', if it is outside the domain of rational evaluation, or ''irrational'', if it belongs to this domain but does not fulfill its standards. There are many discussions about the essential features shared by all forms of rationality. According to reason-responsiveness accounts, to be rational is to be responsive to reasons. For example, dark clouds are a reason for taking an umbrella, which is why it is rational for an agent to do so in response. An important rival to this approach are coherence-based accoun ...

Doxastic Logic
Doxastic logic is a type of logic concerned with reasoning about beliefs. The term ' derives from the Ancient Greek (''doxa'', "opinion, belief"), from which the English term ''doxa'' ("popular opinion or belief") is also borrowed. Typically, a doxastic logic uses the notation \mathcalx to mean "It is believed that x is the case", and the set \mathbb : \left \ denotes a set of beliefs. In doxastic logic, belief is treated as a modal operator. There is complete parallelism between a person who believes propositions and a formal system that derives propositions. Using doxastic logic, one can express the epistemic counterpart of Gödel's incompleteness theorem of metalogic, as well as Löb's theorem, and other metalogical results in terms of belief.

Paul Grice
Herbert Paul Grice (13 March 1913 – 28 August 1988), usually publishing under the name H. P. Grice, H. Paul Grice, or Paul Grice, was a British philosopher of language. He is best known for his theory of implicature and the cooperative principle (with its namesake Gricean maxims), which became foundational concepts in the linguistic field of pragmatics. His work on meaning has also influenced the philosophical study of semantics. Life Born and raised in Harborne (now a suburb of Birmingham), in the United Kingdom, he was educated at Clifton College and then at Corpus Christi College, Oxford.publish.uwo.ca/~rstainto/papers/Grice.pdf After a brief period teaching at Rossall School, he went back to Oxford, firstly as a graduate student at Merton College from 1936 to 1938, and then as a Lecturer, Fellow and Tutor from 1938 at St John's College. During the Second World War Grice served in the Royal Navy; after the war he returned to his Fellowship at St John's, which he held u ...
