Stipulative Definitions
A stipulative definition is a type of definition in which a new or currently existing term is given a new specific meaning for the purposes of argument or discussion in a given context. When the term already exists, this definition may, but does not necessarily, contradict the dictionary (lexical) definition of the term. Because of this, a stipulative definition cannot be "correct" or "incorrect"; it can only differ from other definitions, but it can be useful for its intended purpose.Hurey, Patrick J. ''A Concise Introduction to Logic'', Cengage Learning, For example, in the riddle of induction by Nelson Goodman, " grue" was ''stipulated'' to be "a property of an object that makes it appear green if observed before some future time ''t'', and blue if observed afterward". "Grue" has no meaning in standard English; therefore, Goodman created the new term and gave it a ''stipulative definition''.

Definition
A definition is a statement of the meaning of a term (a word, phrase, or other set of symbols). Definitions can be classified into two large categories: intensional definitions (which try to give the sense of a term), and extensional definitions (which try to list the objects that a term describes).Lyons, John. "Semantics, vol. I." Cambridge: Cambridge (1977). p.158 and on. Another important category of definitions is the class of ostensive definitions, which convey the meaning of a term by pointing out examples. A term may have many different senses and multiple meanings, and thus require multiple definitions. In mathematics, a definition is used to give a precise meaning to a new term, by describing a condition which unambiguously qualifies what the mathematical term is and is not. Definitions and axioms form the basis on which all of modern mathematics is to be constructed. Basic terminology In modern usage, a definition is something, typically expressed in words, that at ...

Theoretical Definition
A theoretical definition defines a term in an academic discipline, functioning as a proposal to see a phenomenon in a certain way. A theoretical definition is a proposed way of thinking about potentially related events. Theoretical definitions contain ''built-in'' theories; they cannot be simply reduced to describing a set of observations. The definition may contain implicit inductions and deductive consequences that are part of the theory. A theoretical definition of a term can change, over time, based on the methods in the field that created it. Without a falsifiable operational definition, conceptual definitions assume both knowledge and acceptance of the theories that it depends on. A hypothetical construct may serve as a theoretical definition, as can a stipulative definition. In different fields Sciences The term scientific theory is reserved for concepts that are widely accepted. A scientific law often refers to regularities that can be expressed by a mathematical state ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Persuasive Definition
A persuasive definition is a form of stipulative definition which purports to describe the true or commonly accepted meaning of a term, while in reality stipulating an uncommon or altered use, usually to support an argument for some view, or to create or alter rights, duties or crimes. The terms thus defined will often involve emotionally charged but imprecise notions, such as "freedom", "terrorism", "antisemitism, "democracy", etc. In argumentation the use of a persuasive definition is sometimes called definist fallacy. (The latter sometimes more broadly refers to a fallacy of a definition based on improper identification of two distinct properties.) Examples of persuasive definitions (definist fallacies) include: * Democrat – "a leftist who desires to overtax the corporations and abolish freedom in the economic sphere". * Atheist – "someone who doesn't yet realize that God exists." Persuasive definitions commonly appear in controversial topics such as polit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equivocation
In logic, equivocation ("calling two different things by the same name") is an informal fallacy resulting from the use of a particular word or expression in multiple senses within an argument. It is a type of ambiguity that stems from a phrase having two or more distinct meanings, not from the grammar or structure of the sentence. Fallacy of four terms Equivocation in a syllogism (a chain of reasoning) produces a fallacy of four terms (). Below is an example: : Since only man umanis rational. : And no woman is a man ale : Therefore, no woman is rational. The first instance of "man" implies the entire human species, while the second implies just those who are male. Motte-and-bailey fallacy Equivocation can also be used to conflate two positions which share similarities, one modest and easy to defend and one much more controversial. The arguer advances the controversial position, but when challenged, they insist that they are only advancing the more modest position. See ...

Connotation
A connotation is a commonly understood cultural or emotional association that any given word or phrase carries, in addition to its explicit or literal meaning, which is its denotation. A connotation is frequently described as either positive or negative, with regard to its pleasing or displeasing emotional connection. For example, a stubborn person may be described as being either ''strong-willed'' or ''pig-headed''; although these have the same literal meaning (''stubborn''), ''strong-willed'' connotes admiration for the level of someone's will (a positive connotation), while ''pig-headed'' connotes frustration in dealing with someone (a negative connotation). Usage "Connotation" branches into a mixture of different meanings. These could include the contrast of a word or phrase with its primary, literal meaning (known as a denotation), with what that word or phrase specifically denotes. The connotation essentially relates to how anything may be associated with a word or phras ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Science
Science is a systematic discipline that builds and organises knowledge in the form of testable hypotheses and predictions about the universe. Modern science is typically divided into twoor threemajor branches: the natural sciences, which study the physical world, and the social sciences, which study individuals and societies. While referred to as the formal sciences, the study of logic, mathematics, and theoretical computer science are typically regarded as separate because they rely on deductive reasoning instead of the scientific method as their main methodology. Meanwhile, applied sciences are disciplines that use scientific knowledge for practical purposes, such as engineering and medicine. The history of science spans the majority of the historical record, with the earliest identifiable predecessors to modern science dating to the Bronze Age in Ancient Egypt, Egypt and Mesopotamia (). Their contributions to mathematics, astronomy, and medicine entered and shaped the Gree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precising Definition
A precising definition is a definition that contracts or reduces the scope of the lexical definition of a term for a specific purpose by including additional criteria that narrow down the set of things meeting the definition. For example, a dictionary may define the term "student" as "1. anyone attending an educational institution of any type, or 2. anyone who studies something." However, a movie theater may propose a ''precising definition'' for the word "student" of "any person under the age of 18 enrolled in a local school" in order to determine who is eligible to receive discounted tickets. Precising definitions are generally used in contexts where vagueness is unacceptable; many law, legal definitions are precising definitions, as are company policies. This type of definition is useful in preventing disputes that arise from the involved parties using different definitions of the term in question. A precising definition is intended to make a vague word more precise so that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logical Argument
An argument is a series of Sentence (linguistics), sentences, Statement (logic), statements, or propositions some of which are called premises and one is the Logical consequence, conclusion. The purpose of an argument is to give Reason (argument), reasons for one's conclusion via justification, explanation, and/or persuasion. Arguments are intended to determine or show the degree of truth or acceptability of another statement called a conclusion. The process of crafting or delivering arguments, argumentation, can be studied from three main perspectives: the logical, the dialectical and the rhetorical perspective. In logic, an argument is usually expressed not in natural language but in a symbolic formal language, and it can be defined as any group of propositions of which one is claimed to follow from the others through Deductive reasoning, deductively valid inferences that preserve truth from the premises to the conclusion. This logical perspective on argument is relevant for sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grue And Bleen
The new riddle of induction was presented by Nelson Goodman in ''Fact, Fiction, and Forecast'' as a successor to problem of induction, Hume's original problem. It presents the logical Predicate (mathematical logic), predicates grue and bleen which are unusual due to their time-dependence. Many have tried to solve the new riddle on those terms, but Hilary Putnam and others have argued such time-dependency depends on the language adopted, and in some languages it is equally true for natural-sounding predicates such as "green". For Goodman they illustrate the problem of projectible predicates and ultimately, which empirical generalizations are Scientific law, law-like and which are not. Goodman's construction and use of ''grue'' and ''bleen'' illustrates how philosophers use simple examples in analytic philosophy, conceptual analysis. Grue and bleen Goodman defined "grue" relative to an arbitrary but fixed time ''t'': an object is grue if and only if it is observed before ''t'' and ...

Nelson Goodman
Henry Nelson Goodman (7 August 1906 – 25 November 1998) was an American philosopher, known for his work on counterfactuals, mereology, the problem of induction, irrealism, and aesthetics. Life and career Goodman was born in Somerville, Massachusetts, the son of Sarah Elizabeth (née Woodbury) and Henry Lewis Goodman. He was of Jewish origins. He graduated from Harvard University, AB, '' magna cum laude'' (1928). During the 1930s, he ran an art gallery in Boston, Massachusetts, while studying for a Harvard PhD in philosophy, which he completed in 1941. His experience as an art dealer helps explain his later turn towards aesthetics, where he became better known than in logic and analytic philosophy. During World War II, he served as a psychologist in the US Army. He taught at the University of Pennsylvania, 1946–1964, where his students included Noam Chomsky, Sidney Morgenbesser, Stephen Stich, and Hilary Putnam. He was a research fellow at the Harvard Center for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
