 With respect to reductionism (the second dogma of empiricism in Quine’s 1951), Quine rightly criticized the viability of Carnap’s radical reductionism in the Aufbau—which, however, Carnap himself gave up soon after the Aufbau’s publication. It is much less clear whether Quine is right to attribute a weaker form of reductionism to the later Carnap, as Carnap regards the confirmation of scientific hypotheses to be holistic and theory-relative from the Logic Syntax at the latest. This is discussed in more detail in the supplement  The Reconstruction of Scientific Theories (Section 1).
