Probability without certainty Foundationalism and the Lewis-Reichenbach debate
No full textLike many discussions on the pros and cons of epistemic foundationalism, the debate between C.I. Lewis and H. Reichenbach dealt with three concerns: the existence of basic beliefs, their nature, and the way in which beliefs are related. In this paper we concentrate on the third matter, especially on Lewis’s assertion that a probability relation must depend on something that is certain, and Reichenbach’s claim that certainty is never needed. We note that Lewis’s assertion is prima facie ambiguous, but argue that this ambiguity is only apparent if probability theory is viewed within a modal logic. Although there are empirical situations where Reichenbach is right, and others where Lewis’s reasoning seems to be more appropriate, it will become clear that Reichenbach’s stance is the generic one. This follows simply from the fact that, if P(E|G) > 0 and P(E|not-G) > 0, then P(E) > 0. We conclude that this constitutes a threat to epistemic foundationalism
Hans Reichenbach: philosopher-engineer
No full textThis thesis relates Hans Reichenbach's philosophy of science both to his historical context and to his interest in the physical world. The thesis begins with a review of his life, and notes the most significant influences on him. His early ambition to become an engineer stimulated in him an active interest in understanding physical things, and his enjoyment in disseminating what he knew entailed that he maintained a keen interest in contemporary ideas. By the age of twenty he had turned to philosophy to enhance his appreciation of science, and was influenced by Kant and the neo-Kantian interpretation through Ernst Cassirer. His subsequent work is concerned with providing philosophical explication of the major innovations of twentieth century science, and particularly of the implications of Einstein’s Theories of Relativity and of Quantum Mechanics. The thesis proceeds by summarising Kant's and Cassirer's writings on the philosophy of science before examining Einstein's theories. Subsequent chapters analyse Reichenbach's most significant publications in chronological order, namely The Theory of Relativity and A Priori Knowledge (1920), The Philosophy of Space and Time (1928), Experience and Prediction (1938),Philosophic Foundations of Quantum Mechanics (1944), and The Direction of Time (1956). The chapter on Quantum Mechanics is introduced with a summary of the scientific concepts introduced prior to Reichenbach's writing about them. Although he demonstrates the shortcomings of Kant's philosophical justification, the objective Reichenbach set himself throughout his work was to identify the principles that regulate our empirical knowledge. Despite his close friendship with Rudolf Carnap and Moritz Schlick, he differentiated his Empiricism from Logical Positivism, and he refused to accept that Conventionalism could offer a satisfactory analysis of knowledge of the objective world. The final chapter summarises the impact of his writing and his major contribution to philosophy
