Abstract

"It makes no sense to ask for justification, or to question the legitimacy, of linguistic forms," V. Kraft writes in his book The Vienna Circle (p. 60). "One should instead pay homage, in the logical analysis of language, to a principle of tolerance." And in Note 65 of his book, the historian of the Circle continues: "This was emphasized for the first time by K. Menger in the controversy about the foundations of mathematics ("Der Intuitionismus", 1930)" — herein Chapter 2 — "and thereafter K. Popper endorsed this point of view as a regular tenet of the logic of science (The Logic of Scientific Discovery, 1935)."
