reduktio

Reduktio is a term used in various disciplines to denote the act or process of reducing something to a simpler, more essential form. The word derives from Latin reductio, meaning a bringing back or a leading back, and in several languages it appears as Reduktio or a closely related cognate. As a general concept, it encompasses simplification, abstraction, and derivation from a more complex structure.

In philosophy and logic, Reduktio is closely linked to reductio ad absurdum, a method of argument that assumes a proposition is true and proceeds to deduce a contradiction. When this contradiction is established, the original proposition is rejected as false. This method is used to demonstrate the untenability of hypotheses and to illuminate the logical consequences of assumptions.

In scientific and mathematical contexts, Reduktio describes approaches that reduce problems to simpler components or models. This may involve deriving a reduced model that preserves essential behavior, or transforming a problem into a known, solvable form. In computing, problem reductions or reductions between decision problems are common techniques in complexity theory and algorithm design.

Usage of Reduktio varies by discipline and language, and the term is less a formal technical label and more a descriptive notion of reduction. Readers should consider context to distinguish it from related terms such as reduction, reductive reasoning, or reductio ad absurdum. See also reductio ad absurdum; reduction; model reduction; simplification.
