Learn vocabulary, terms, and more with flashcards, games, and other study tools. For example, … As the name might suggest, this is the type of definition used in Linnaean taxonomy to categorize living things, but is by no means restricted to biology. The two phrases, “morning star”and “evening star” may d… Intension and extension, in logic, correlative words that indicate the reference of a term or concept: “intension” indicates the internal content of a term or concept that constitutes its formal definition; and “extension” indicates its range of applicability by naming the particular objects that it denotes. § 63. There must be more to it than this. Any definition that attempts to set out the essence of something, such as that by genus and differentia, is an intensional definition. n. 1. The set E of whole multiples of 2 can be defined intensionally like this: E = \(\left\{ x\in \mathbb{N}\ \Big\vert\ x\div 2\in \mathbb{N}\right\}\) . [1], This is the opposite approach to the extensional definition, which defines by listing everything that falls under that definition – an extensional definition of bachelor would be a listing of all the unmarried men in the world.[1]. Mathematics Stack Exchange is a question and answer site for people studying math at any level and professionals in related fields. One way is by intensional definition, using a rule or semantic description: A is the set whose members are the first four positive integers. Naively, we mightsay the morning star and the evening star are the same in one way, andnot the same in another. Does builders risk cover general liability? [1.] It is the permanent part of the relation. This is similar to an ostensive definition, in which one or more members of a set (but not necessarily all) are pointed out as examples. In linguistics, logic, philosophy, and other fields, an intension is any property or quality connoted by a word, phrase, or another symbol. § 60. For example: Suppose we say that to love someone is to be willing to die for that person. In logic, philosophy, and mathematics, extensional and intensional definitions are two key ways in which the object(s) or concept(s) a term refers to can be defined. Intensional definition. Extensional definition. Living life with intention means merely to become the leading agent of your own life. extensional definitions by themselves cannot properly serve as precising definitions for the following reason. B is a set of six positive integers. Extensional meaning: is made of the members of the class that the term denotes, and denotes means to signify directly or refer to specifically. The extensional meaning of a term consists of the members of the class denoted by the term. For example, A is a set whose members are cars. Intensional definition also applies to rules or sets of axioms that define a set by describing a procedure for generating all of its members. In Part 2, we explore temporal matters. extension, in logic, correlative words that indicate the reference of a term or concept: “intension” indicates the internal content of a term or concept that constitutes its formal definition; and “extension” indicates its range of applicability by naming the particular objects that it denotes. lies in the objects denoted, not in the way of denoting them. It only takes a minute to sign up. Definition by genus and difference, in which something is defined by first stating the broad category it belongs to and then distinguished by specific properties, is a type of intensional definition. [3] He seemed to think that I was trying to cause problems, but that was never my intention. Mathematics is typically extensional throughout—we happily write “ 1 + 4 = 2 + 3 ” even though the two terms involved may differ in meaning (more about this later).

The rule—"take an integer and multiply it by itself"—always generates members of the set of square numbers, no matter which integer one chooses, and for any square number, there is an integer that was multiplied by itself to get it. Extensional definitions are used when listing examples would give more applicable information than other types of definition, and where listing the members of a set tells the questioner enough about the nature of that set. Definition may also refer to: . Intension and Extension describe two ways of indicating the meaning of a word or name. Definition. (logic, mathematics) The condition of having an intension. . Click to see full answer. have no intention/have every intention. . [3] Any definition that attempts to set out the essence of something, such as that by genus and differentia, is an intensional definition. this definition complies with the mathematical requirements of a definition, it will empower rigorous analytical approaches to study civilizations. Intensional definition. phrase. (9)Generics Bears like honey. A language is intensional if it contains intensional statements, and extensional otherwise. Extension is the set of objects in the world to which the word corresponds. Platonism and intuitionism are rival philosophies of Mathematics, the former holding that the subject matter of mathematics consists of abstract objects whose existence is independent of the mathematician, the latter that the subject matter consists of mental construction . It corresponds to what is specified in the relational schema. The notion of the and identity § 65. What is internal and external criticism of historical sources?

EXTENSIONAL VS. INTENSIONAL LOGIC Jaroslav Peregrin 1 FREGE’S BEDEUTUNG The German mathematician and one of the founding fathers of modern logic, Gottlob Frege (1848-1925), was the first to clearly realize that semantics has little to do with psychology, and that it could be usefully explicated in mathematical terms (see Dummett, 1973; 1981). If you say that you have every intention of doing something, you are emphasizing that you intend to do it. Similarly, you may ask, what is the difference between extensional and intensional? It is impossible to give an extensional definition for a term with an infinite set of referents, but an intensional one can often be stated concisely – there are infinitely many even numbers, impossible to list, but the term "even numbers" can be defined easily by saying that even numbers are integer multiples of two. However, an intensional definition gives the meaning of words by specifying the way they should be used. These are terms known as empty extension, and like the name implies these are words taht denote a null class, meaning a group or class with no memebers.

Similarly, an intensional definition of a game, such as chess, would be the rules of the game; any game played by those rules must be a game of chess, and any game properly called a game of chess must have been played by those rules.

He bought a dog with the intention of training it to attack intruders. (logic, mathematics) The condition of having an intension.

It can be contrasted to extensional logic In the case of nouns, this is equivalent to specifying the propertiesthat an objectneeds to have in order to be counted as a referentof the term. For example, A is a set whose members are cars. both views are implicitly opposed to materialistic accounts of mathematics which take the subject matter of … In the case of a word, the word's definition often implies an intension.
