This course traces the steps by which irrational philosophy ended the glorious era of physics that began with the achievement of Isaac Newton. The story takes place mainly in Germany, where, as a result of Kant's influence,physicists turned against Newton and embraced mysticism in the early 19th century. The bankruptcy of this approach led Ger-man physicists to posihvism, the empiricist side of Kant's coin.Mr. Harriman discusses the Kantian attack on the conceptual foundations of physics that culminated in the subjectivism of relativity theory and in the rejection of causality in quantum theory. No specialized knowledge of physics is required. 

(This is a repeat of the course given at a previous conference.)
