c
- The name used in Factasia for pure combinatory logic.
- calculus ratiocinator
- (after Leibniz) a mechanical method of solving problems which have been expressed in a universal language known as a characteristica universalis).
-
casuist
- a person who resolves problems of conscience or duty
- cardinal
- chief, fundamental
- cardinal number
-
- numbers denoting quantity ("one", "two", "three", ...), as opposed to ordinal numbers indicating position ("first", "second", "third", ...).
- An equivalence class generated by the relation "same size as" obtaining when there is a one-one mapping between the elements of two sets.
- The smallest ordinal number of some size.
- see also:
- large cardinal
- category
- a class or division
- (philosophy, metaphysics)
- one of the fundamental kinds of things (see: Aristotle's Categories)
- (mathematics)
- a kind of mathematical structure, providing in some respects a very general mathematical counterpart to the notion of a concept.
A collection of objects and of morphisms (or arrows) such that each morphism has a domain and codomain which are objects, each object has an identity morphism, and morphisms compose associatively.
e.g. corresponding to the mathematical concept of a group there is a category of groups which contains as objects all the groups, and as arrows between these objects the group homomorphisms.
- category mistake
- a favourite kind of "philosophical puzzlement" to which the Oxford philosopher Gilbert Ryle drew attention.
A category mistake occurs when a speaker or writer applies a concept outside the domain in which it can meaningfully be applied (often in the course of formulating some philosophical theory).
- see also:
- kind
- sort
- type
- characteristica universalis
- (after Leibniz) a universal language into which any kind of problem can be translated (and then solved by calculation using a calculus ratiocinator).
See: The Method of Mathematics.
- class
- a collection of persons or things
- (logic)
- sometimes used interchangeably with or instead of set, sometimes used (e.g. in NBG) for collections which are "too large" to be sets.
- coerce
- persuade or restrain (an unwilling person) by force
- coercion (1)
- the act or process of coercing
- coercion (2) (computing)
- the automatic conversion of a value in a computer program from one type to another as needed for the use made of the value in some particular context, e.g. the conversion of an integer to a floating point number before adding it to some other floating point number.

- anarchism
-
cofinal
- a function into an ordinal is cofinal if its range is unbounded in its codomain.
-
cofinality
- the cofinality of an ordinal
, cf(
), is the least ordinal
which maps cofinally into
.
-
cognition
- knowing, perceiving or conceiving as distinct from emotion or volition.
-
combinator
- a function primitive to or definable in pure combinatory logic
-
combinatory logic
- a form of logic in which bound variables are not used
- complex
- Not simple. Not atomic. Structured.
- complex number
- A number formed of two parts, so called real and imaginary parts, both of which are real numbers.
-
computer
- An electronic device which stores and processes data following instructions which are also stored in its memory (and can therefore easily be changed).
- computer algebra
- the use of computer programs which automate algebraic transformations, e.g. MACSYMA, Maple, Mathematica.
-
conjunct
- One of the immediate constituent sentences of a conjunction, e.g. in "A and B" the conjuncts are "A" and "B".
-
conjunction
- A compound sentence of the form "A and B".
-
constructive
-
- constructive logic
- A logic is constructive if existence proofs in the logic depend upon constructing something with the required property and may not proceed by reductio-absurdum.
-
contingent
- Might have been otherwise.
