| Constants, philosophy, logic: constants are conditions which do not change, in contrast to processes, states, and also natural objects, e.g. aging. An aging human being remains constantly the same person, but not the same body. For a constant, e.g. a name for an object is given. Letters of logic are given for individual constants (a, b, c ...), but also for individual variables (x, y, z ...). Variables are not changing objects, but a new object may be used instead of a variable, e.g. 4 instead of 5. These two numbers, however, are not changing objects, but have a constant value._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them. Instead, they are intended to give a short introduction to the contributions below. – Lexicon of Arguments. | |||

Alfred Tarski on Constants - Dictionary of Arguments
Berka I 496 Names/variables/constants/Tarski: variables represent names constants are names. >Representation, > Proxy, >Variables. For each constant and each variable of the object language (except for the logical constants of the propositional calculus) we can constitute a fundamental feature that contains this sign. The statement variables enter into the fundamental functions neither as functors nor as arguments. Statement variable: any ((s) individual) of them is regarded as an independent fundamental function.(1) >Object language, >Metalanguage. 1.
