In 1909 A. Koyré (1892–1964) came to Göttingen as an exile and there became a student of Edmund Husserl and other philosophers (A. Reinach, M. Scheler): already before leaving his country Russia Koyré read Husserl'sLogical Investigations, a text which interested greatly Russian philosophers and was translated into Russian in the same year. As many other contemporary philosophers, in Göttingen they were discussing on the fundaments of mathematic, Cantor's set theory and Russell's antinomies. On this problems Koyré wrote a long paper (...) inspired to Husserl'sLogical Investigations, read it in the Philosophical Society at Göttingen and submitted it as draft for his Ph.D. dissertation to Prof. Husserl, who refused it. So unhappily the celebrated methodologist and historian of science began his academical career: Koyré came back to write on logical and mathematical paradoxes in 1922 and in 1946–47 saying he was “going back to his first love”. Among other factors this deep interest in mathematic and exact sciences unabled Koyré to analyze Galileo and Newton in his masterly way. (shrink)
