| | Type theory - Wikipedia, the free encyclopedia |
 | | For example, a type system may classify the value "hello" as a string and the value 5 as a number, and prohibit the programmer from adding "hello" to 5 based on that type assignment. | | | With the rise of powerful programmable computers, and the development of programming languages for the same, type theory has found practical application in the development of programming language type systems. | | | [A type system is a] tractable syntactic method for proving the absence of certain program behaviors by classifying phrases according to the kinds of values they compute. |

| | In the hard sciences, a theory is a model or framework for understanding. | | | A good example of a non-scientific "theory" is Intelligent Design. | | | This is true of such established theories as evolution, special and general relativity, quantum mechanics (with minimal interpretation), plate tectonics, etc. |

| | PlanetMath: Russell's theory of types |
| | In order to overcome this, Russell introduced the notion of types (which are today known as degrees). | | | In Frege's system this is easy to overcome: the equicardinality predicate is defined for extensions of predicates, which are objects. | | | It is not known if NF axiomatises any extensor (see the entry class) based on a limitation of size principle, like the more familiar set theories do. |

| | Using Theory |
| | Useless theories can be made to work by informal and often unconscious truncation or augmentation by the would-be user. | | | Endogenous variables cannot (theoretically) be identified independently of the system; the system is defined by the variables in it and their interrelation. | | | See pages 54 through 57 in Ludwig Von Bertalanffy, General System Theory (New York: Brasilier, 1968) A system is a set of variables changes in any of which is a function of all of the variables in the set. |

| | Furthermore, the term "type" as used in computer science is broad enough to include the meanings of both "sort" and Russell's notion of "type". | | | In the simple theory, types are essentially > classes of similar objects: the lowest type is the class of all > individuals, the next the class of all classes of individuals, and so > on. | | | The problem is that >> computer science needs both sorts and types in the mathematical sense. |

| | Computer-Assisted Reasoning based on Type Theory (TYPES) |
| | The aim of our research activities is to develop the technology of formal reasoning based on Type Theory by improving the languages and tools of reasoning and by applying the technology in several domains such as programming languages, certified software, and formalisation of mathematics. | | | This project is based on the strong collaboration and achievements in three successful European projects (ESPRIT BRA and Working Group), in which we have built several computer systems for proof development and used them in applications. | | | The subject of this project is Computer-Assisted Formal Reasoning, an area which is of deep interest for industry. |

Russell that rules out self-reference in order to prevent the emergence of antinomies and paradoxes in logic. | | | However, by exorcising self-reference, the theory of logical types bas retarded the development of theory, largely cognitive theory, in areas where self-reference is prevalent. |
