Quotes About Operationalism

Operationalism, created by Nobel physicist Percy W. Bridgman, attempts to deal with the common sense objections to Relativity and Quantum Mechanics, and owes a great deal to pragmatism and instrumentalism. Bridgman explicitly pointed out that common sense derives unknowingly from some tenets of ancient philosophy and speculation — particularly Platonic Idealism and Aristotelian essentialism — and that this philosophy assumes many axioms that now appear either untrue or unprovable.

The Copenhagen Interpretation of quantum physics, created by Niels Bohr (another Nobel winner), says much the same as operationalism, in even more radical language. According to Bohr, common sense and traditional philosophy both have failed to account for the data of Quantum Mechanics (and of Relativity) and we need to speak a new language to understand what physics has discovered.
