  After a short summary of the Sokal Affair and of the point of view of Steven
Weinberg, we discuss certain aspects of the scientist ideology present in the
last book of Alan Sokal "Pesudoscience ans Postmodernism: Antagonists or
Fellow-Travellers?", published in France. The danger of the three extremisms
present in our time - relativist extremism, scientist extremism and its
mirror-image, the religious extremism - is underlined. We point out also the
necessity of a transdisciplinary dialogue between the different disciplines as
a rampart against the fascination caused by these three extremisms.
