Examines the changes during the twentieth century in the views of mathematics, physics, and the scientific method and discusses the role of the mind in science.

Experiment, instrumentation, and procedures of measurement, the body of practices and technologies forming the technical culture of science, have received at most a cameo appearance in most histories. For the history of science is almost always written as the history of theory. Of course, the interpretation of science as dominated by theory was the main pillar of the critique, launched by Kuhn, Quine, Hanson, Feyerabend, and others, of the positivist and logical empiricist traditions in the philosophy of science. Against Carnap, (...) Hempel, Nagel, and Popper, who accorded observation reports an independent status either as a source of inductive support or as a basis for the falsification of scientific theories, Hanson and Kuhn emphasized the theory-ladenness of observation. They made this central point – that all observation is shaped by reference to theory – the cornerstone of a full-blown philosophy of science by buttressing it with two additional lines of argument: First, theories are always underdetermined by the data, several theories being compatible with the same set of data. Hence, choice between theories is never a matter of empirical support, but always turns around conceptual issues. Second, statements derived from theory never confront nature alone; they are always clothed in a web of interrelated beliefs. Thus, theories, their associated observation languages, and the entire technical culture they support must be accepted or rejected as wholes. (shrink)

The ArgumentBehind the dispute over the relative priority of theory and experiment lie conflicting philosophical images of the nature of scientific inquiry. One crucial image arose in the 1920s, when the logical positivists agitated for a “unity of science” that would ground all meaningful scientific activity on an observational foundation. Their goals and rhetoric dovetailed with the larger movements of architectural, literary, and philosophical modernism. Historians of science followed the positivists by tracking experimental science as the basis for scientific progress. (...) After World War II, historians and philosophers of science created an antipositivist movement, inverting the positivist idea that observation had epistemic priority. But this counter-movement retained the modernist aspiration to unity, now chaining observation to theory. Once again historians of science, following their philosophical colleagues, illustrated the new modernism with historical instances of observation dominated by theory.Either reductionist scheme, by privileging one activity over the other, dictates an overly constrictive periodization. We need a wider class of periodization models that will allow instrumentation, experimentation, and theory a partial autonomy without granting any one the sole legitimate narrative standpoint. Such a heterogeneous representation of historical traditions may, surprisingly, make better sense of the perceived coherence of activity across theoretical transitions than the monolithic modernist representation of science it displaces.
