 What Stebbing found attractive in logical positivism was its respect for science and the value it placed on logic. What she rejected was its repudiation of metaphysics. (She endorsed the “logical” and “empiricism” but not the “positivism”, in other words, of the movement for which both “logical empiricism” and “logical positivism” are used as names, more or less interchangeably.) We can see her 1932 paper, “The Method of Analysis in Metaphysics”, as seeking to defend the conception of metaphysical analysis of the Cambridge School in response to the logical positivists’ critique of metaphysics. But it is in a paper she read to the British Academy in March 1933, “Logical Positivism and Analysis”, that she attempts to engage directly with logical positivism and say what she finds objectionable about it. She takes “logical positivism” to include the views of Wittgenstein, as filtered through the reports and writings of various members of the Vienna Circle such as Schlick, Carnap, and Friedrich Waismann. Focusing especially on Carnap, she criticizes his conception of “logically constructed systems” (as found in his Aufbau of 1928, for example) for being too abstract. However useful such a system may be in showing what can be constructed with the fewest possible assumptions and primitive terms, she argues, the world itself is not such a system. She also attacks Carnap’s “methodological solipsism” on what she calls “the best of grounds … namely, that I know it to be false” (1933a: 77).
