Logical Empiricism
Historical and Contemporary Perspectives
Paolo Parrini
University of Pittsburgh Press, 2003

Logical empiricism, a program for the study of science that attempted to provide logical analyses of the nature of scientific concepts, the relation between evidence and theory, and the nature of scientific explanation, formed among the famed Vienna and Berlin Circles of the 1920s and '30s and dominated the philosophy of science throughout much of the twentieth century. In recent decades, a "post-positivist" philosophy, deriding empiricism and its claims in light of more recent historical and sociological discoveries, has been the ascendant mode of philosophy and other disciplines in the arts and sciences.

This book features original research that challenges such broad oppositions. In eleven essays, leading scholars from many nations construct a more nuanced understanding of logical empiricism, its history, and development, offering promising implications for current philosophy of science debates.

Tapping rich resources of unpublished material from archives in Haarlem, Konstanz, Pittsburgh, and Vienna, contributors conduct a deep investigation into the origins and development of the Vienna and Berlin Circles. They expose the roots of the philosophy in such varied sources as Cassirer, Poincaire, Husserl, Heidegger, and Wittgenstein. Important connections between the empiricists and other movements--neo-empiricism, British empiricism--are vigorously explored.

Building on these historical studies, a critical reevaluation emerges that shrinks the distance between old and new philosophers of science, between "analytic" and "Continental" philosophy. A number of compelling recent debates, including those involving Kuhn, Feyerabend, Hesse, Glymour, and Hanson, are reopened to show the ways in which logical empiricist theory can still be validly applied.

Logical Empiricism is the result of a remarkable conference, convened in the spirit of reflection and international cooperation, that took place in Florence, Italy, in 1999.

On Theories
Logical Empiricism and the Methodology of Modern Physics
William Demopoulos
Harvard University Press, 2022

A renowned philosopher’s final work, illuminating how the logical empiricist tradition has failed to appreciate the role of actual experiments in forming its philosophy of science.

The logical empiricist treatment of physics dominated twentieth-century philosophy of science. But the logical empiricist tradition, for all it accomplished, does not do justice to the way in which empirical evidence functions in modern physics.

In his final work, the late philosopher of science William Demopoulos contends that philosophers have failed to provide an adequate epistemology of science because they have failed to appreciate the tightly woven character of theory and evidence. As a consequence, theory comes apart from evidence. This trouble is nowhere more evident than in theorizing about particle and quantum physics. Arguing that we must consider actual experiments as they have unfolded across history, Demopoulos provides a new epistemology of theories and evidence, albeit one that stands on the shoulders of giants.

On Theories finds clarity in Isaac Newton’s suspicion of mere “hypotheses.” Newton’s methodology lies in the background of Jean Perrin’s experimental investigations of molecular reality and of the subatomic investigations of J. J. Thomson and Robert Millikan. Demopoulos extends this account to offer novel insights into the distinctive nature of quantum reality, where a logico-mathematical reconstruction of Bohrian complementarity meets John Stewart Bell’s empirical analysis of Einstein’s “local realism.” On Theories ultimately provides a new interpretation of quantum probabilities as themselves objectively representing empirical reality.
