|Reduction, philosophy: reduction is the tracing back of a set of statements to another set of statements by rephrasing and replacing concepts of a subject domain by concepts from another subject domain. There must be conditions for the substitutability of a concept from the first domain by a concept from the second domain. An example of a reduction is the tracing back of mental concepts to physical concepts or to behavior. See also bridge laws, reductionism, translation, identity theory, materialism, physical/psychical, physicalism, eliminationism, functionalism, roles, indeterminacy._____________Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Reduction / Stalnaker: E.g. of theories: one describes the terms of a less fundamental theory in terms of the more fundamental - that shows you that the former can be derived from the latter.
Reductionism / reduction / Stalnaker: a) semantically: replace expressions by expressions - relation between theories - b) metaphysically: Relation between sets of properties or facts, not theories. - Reduction may fail: e.g. r. meteorology to physics: basic: physics does not provide a complete description of the world. - Supervenience: helps to distinguish the important from the semantic (irrelevant) part of a reductionist theory._____________Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
