This article deals with Moritz Schlick's critical realism and its sources that dominated his philosophy until about 1925. It is shown that his celebrated analysis of Einstein's relativity theory is the result of an earlier philosophical discussion about space perception and its role for the theory of space. In particular, Schlick's "method of coincidences" did not owe anything to "entirely new principles" based on the work of Einstein, Poincaré or Hilbert, as claimed by Michael Friedman, but was already in place (...) before these principles were developed. The first part of the article is devoted to Alois Riehl's critical realism—a neo-Kantian variant which rejects the dominant interpretation of the thing-in-itself as a mere limiting concept and takes empirical theories of space perception into consideration. The second part deals with the central role of "Psychological Parallelism" for Riehl and its integration with Kant's epistemology. In the third part it is shown that Schlick's theory of knowledge is based on Riehl's intricate reworking of Kantian epistemology, physiological psychology, theory of sense perception and philosophy of mathematics. The conclusion stresses the position of the unity of consciousness in Riehl's philosophy which Schlick admittedly cannot cope with. (shrink)

The present paper attempts to show that a 1915 article by Erich Kretschmann must be credited not only for being the source of Einstein’s point-coincidence remark, but also for having anticipated the main lines of the logical-empiricist interpretation of general relativity. Whereas Kretschmann was inspired by the work of Mach and Poincaré, Einstein inserted Kretschmann’s point-coincidence parlance into the context of Ricci and Levi-Civita’s absolute differential calculus. Kretschmann himself realized this and turned the point-coincidence argument against Einstein in his second (...) and more famous 1918 paper. While Einstein had taken nothing from Kretschmann but the expression “point-coincidences”, the logical empiricists, however, instinctively dragged along with it the entire apparatus of Kretschmann’s conventionalism. Disappointingly, in their interpretation of general relativity, the logical empiricists unwittingly replicated some epistemological remarks Kretschmann had written before General Relativity even existed.

The aim is to examine Alois Riehl’s contribution to the “culture war” (Kulturkampf) in the second half of the nineteenth century. We show that he used Kant’s autonomy principle to argue against the idea that religious dogmatism is a fundament of morality. We prove this thesis by focusing on the forgotten historical background, which is important for an understanding of Morals und Dogma. Originally this essay was an expert opinion for the court case of the socialist H. Tauschinski who was (...) accused of blasphemy. Tauschinski wrote an article in which he doubted the immortality of the soul and the existence of a personal God. These two dogmas of the Catholic Church were considered bу the Austrian authorities to be the foundations of public order. Riehl questioned not only the charge but also the validity of religious dogmas for morality. Based on Kant’s ethics, he argued for a moral indifferentism of religious dogmas. His career was significantly influenced by this essay, because of its anti-clerical content. During the culture war, Riehl repeatedly had problems with the authorities, especially in the Austro-Hungarian monarchy. The “Neurath-Haller Thesis” argues that in Austria the appointment of professorships was controlled and monitored by the state, with the goal of installing a philosophy which was beneficial to the interests of the state, and a strong anti-Kantianism in Austrian Philosophy as a consequence. We can agree with this thesis insofar as Riehl in the period of the “Catholic Renaissance” in Austria was not allowed to succeed Ernst Mach. The analysis of Riehl’s arguments allows us furthermore to understand Riehl as a neo-Kantian as early as 1871/1872, which has been questioned by many authors who think the early Riehl was no Kantian.
