So the eight papers in this volume, all on Carnap and all given at a conference in Vienna, represent a homecoming of sorts. But the papers do not confine themselves to Carnap alone or to his time in Vienna. They explore his history and motivation, his interaction with other philosophers in both Europe and America, various aspects of his work on logic and philosophy of sci- ence, and even his political engagement. The conference at which these papers were presented, “Rudolf Carnap and the Legacy of Logical Empiricism”, was held on the 28th and 29th of June, 2010 at the University of Vienna, under the auspices of the Institute Vienna Circle. The meeting was organized jointly by Friedrich Stadler for the Institute and by Richard Zach on behalf of the Collected Works of Rudolf Carnap, forthcoming from the Open Court Publishing Company. Carnap wanted philosophy to be scientific, that is, a progressive, coopera- tive venture. But as Michael Friedman shows the ideal of a scientific philosophy appeared long before Carnap and continues to inspire many philosophers even today. Logic was central to Carnap’s vision of a scientific philosophy, and Georg Schiemer explores one of Carnap’s large-scale logic projects, the Untersuchungen zur allgemeinen Axiomatik. This work was set aside in the 1930s and published only well after Carnap’s death. Schiemer is able to show that the work is subtle and gives important clues to Carnap’s thinking in logic. Philosophy of science was also central to Carnap’s vision of philosophy. Matthias Neuber explores the scientific realism defended by Hans Reichenbach and Eino Kaila and Carnap’s resistance to it. Richard Creath examines the related issue of Carnap’s proposal for endow- ing theoretical terms with meaning by tying theories to their Ramsey sentences. Christian Damböck examines another empirical tradition, “German” empiricism, especially as exemplified by Wilhelm Dilthey, and assesses its influence on Car- nap’s view in the Aufbau. Christoph Limbeck-Lilienau and Thomas Mormann, in their separate papers, explore the relations between Carnap and American pragmatism. They approach this topic differently, but each shows that this relation is both complex and illu- minating. Finally, Thomas Uebel examines the political dimension of the Vienna Circle and particularly of Carnap within it. Uebel shows that logic and philosophy of science were from the beginning conceived of as part of a larger project that was indeed political in the broadest sense. Taken together, the papers show the rich variety of Carnap’s concerns and his place within important intellectual traditions that shape our thinking even today. vii v iii Editorial Thanks go to the organizers of the conference, Friedrich Stadler and Richard Zach, to the host institutions, the Institute Vienna Circle and the University of Vienna, to the conference participants, and to the production team at the Institute. Richard Creath Tempe, Arizona, July 7, 2011 Michael FriedMan S P h cientiFic hiloSoPhy FroM elMholtz to c Q arnaP and uine The concept of a “scientific philosophy” (wissenschaftliche Philosophie) first de- veloped in the mid nineteenth century, as a reaction against what was viewed as the excessively speculative and metaphysical character of post-Kantian German ideal- ism. One of the primary intellectual models of this movement was a celebrated address by Hermann von Helmholtz, “Über das Sehen des Menschen,” delivered at the dedication of a monument to Kant at Königsberg in 1855. Helmholtz begins by asking, on behalf of the audience, why a natural scientist like himself is speak- ing in honor of a philosopher. This question only arises, he says, because of the current deplorable climate of enmity and mutual distrust between the two fields – a climate which is due, in Helmholtz’s opinion, to the entirely speculative system of Naturphilosophie that Schelling and Hegel have erected wholly independent of, and even in open hostility towards, the actual positive results of the natural sci- ences. What Helmholtz is now recommending, however, is a return to the close cooperation between the two fields exemplified in the work of Kant, who himself made significant contributions to natural science (in his nebular hypothesis put forward in 1755), and, in general, “stood in relation to the natural sciences together with the natural scientists on precisely the same fundamental principles.”1 And it was this recommendation that was enthusiastically embraced within the emerging “back to Kant!” movement, where it led to the idea that all metaphysics should be replaced by the new discipline of “epistemology” or “theory of knowledge” (Erk- enntnistheorie), so that philosophy itself would now become “scientific.” What is the nature of this new scientific philosophy that is now being ex- plicitly opposed to Naturphilosophie in particular and post-Kantian idealism in general? What relation is philosophy now supposed to bear to the sciences, and what does it mean for philosophy to become scientific in this way? What exactly is being recommended when we are told that philosophy should stand “in relation to the natural sciences together with the natural scientists on precisely the same fundamental principles”? For Helmholtz himself this means that philosophy – that is, epistemology or the theory of knowledge – should work in cooperation with the latest psycho- physiological research in inquiring into the nature of the representations of our senses, and the relationship between these representations and the actual world to which they correspond. And it is for this reason that the body of his 1855 address 1 See Helmholtz (1865/1903, vol. I, p. 88). R.
