Operationalism

from Wikipedia, the free encyclopedia

The operationalism (from the Latin operatio. Performing), sometimes Operationismus called, marks the thesis that the meaning of a term of no more than there is a series of operations.

The question epistemological position goes back to the physicist Percy Williams Bridgman , who in his 1927 published The Logic of Modern Physics with the epistemological interpretation of the theory of relativity apart sets.

Bridgman's strict operationalism

In Bridgman's view, scientific objectivity is based on the use of operational definitions . For a scientific term to be empirically valid, it must be defined in the form of specific measurement methods; just as "length" is defined by applying a meter rule to the respective object to be measured. The meaning of a term is exhausted in a series of measurable measuring operations; the term is synonymous with the operations concerned. Thus Bridgman has not only the criteria of validity ( validity settled) a concept outside of human consciousness, but equated the concept itself with a lot of awareness of independent operations.

Critique of Operationalism

While the expression “ operational definition ” has found general, if not always particularly precise, use, Bridgman's epistemological radical position, the reduction of importance to measurement operations, has met with sharp criticism. The position is methodologically untenable because the theory-dependent meaning of a term is fundamentally independent of the corresponding measurement method; the latter merely indicate under which empirical conditions one can speak of the corresponding phenomenon or an empirical realization of the term. The meaning of a term is by no means limited to a single, specific measurement method; it is theoretically possible and permissible that one and the same term can be measured using different methods. As with Rudolf Carnap's analogous attempt at reduction , reference is made to unsolved difficulties in defining dispositional terms, namely basically by the fact that terms are "theory-impregnated".

For Hilary Putnam it is "well known" that Bridgman's "strict operationalism" "fails to do justice to the actual use of scientific and everyday expressions." Liberalized versions of operationalism like those of Carnap or Ramsey would do justice to actual use, but "only by making a miracle out of the communicability of scientific results ." "No operational definition [provides] a necessary and sufficient condition for the application of any such word".

According to Karl Popper , universals or dispositional expressions transcend what is given by the respective experience. The hope that by solving the problem of the subjunctive conditional clauses an operational definition of the universals can be achieved is therefore unfounded.

Methodological and philosophical reception and parallels

Psychological behaviorism was linked to operationalism by its founder Burrhus Frederic Skinner . Herbert Dingle's approach had many parallels with Bridgman, but also rationalistic accents.

Hugo Dingler's “Operativismus” is not to be confused with “Operationalismus” because, in contrast to Bridgman, he sets up a philosophical justification program ( Certismus ) in order to justify the natural sciences in a safe and exact way through a system of operations. Dingler reviews Bridgman's main work and himself develops a theory of a general constructivist approach, in the history of which the Erlangen constructivism is also included - Paul Lorenzen becomes a student of Dingler.

Parallels to Bridgman's early operationalism can be seen in Rudolf Carnap . Science theorists such as S. Toulmin , WH Watson, and NR Hanson are also credited with related ideas. They are also influenced by Ludwig Wittgenstein's view that the meaning of linguistic expressions results from their use.
