Abstract

Operationism may tentatively be defined as that scientific method which defines its concepts in terms of observable or communicable operations, however carried out. With few exceptions, it has been put forward as representing positivism in contemporary sociology. Sellars refers to it as a new and virulent form of positivism—logical positivism. In philosophy, logical positivism is the culmination of the sensationalism of Berkeley and Hume, the positivism of Mach and Avenarius and Comte, and the logistic of Russell and Wittgenstein. In sociology, the philosophic assumptions of this school have been stated in a naive form, in addition to presenting Kantian idealism contradicted by an assumption of philosophic realism.
