David Berlinski on "The Ineffable Higgs"

David Berlinski: The Ineffable Higgs  (Evolution News & Views, 11/16/2012)
In the final, Berlinski makes the following  "categoricity argument" that is both interesting and bold:  "... consistent theories need not be satisfied in a single model or universe. The conclusion [...] is inevitable. There is no such thing as the world, or the universe to which the SM unequivocally points. And so there can be no large and general conclusions about what the study of the world, the universe, or of Nature reveal about the existence of God."
