Abstract

Although some of Helmholtz’s scientific suggestions are dated with the progress of science, his ontological statements as well as his epistemological studies are still an object of philosophical controversy. The selection of Helmholtz’s epistemological writings, edited as volume 79 in the Synthese Library, contains four papers originally published in German between 1868 and 1887. In these papers are considered among others the epistemological aspects of measuring and numbering, the issues of perceptual cognition, the theory of geometrical knowledge, and the relationship between science and metaphysics. The present collection of the Helmholtz’s articles was previously edited in German, on the centenary of his birth, under the title Schriften zur Erkenntnistheorie. The editors, M. Schlick and P. Hertz, sharing the opinion that Helmholtz’s name is a symbol of a union between epistemologically oriented philosophy and science, had selected from his many epistemological writings only four—the most representative and the most complete. In order to make the papers intelligible not only to philosophers but also to general readers, Schlick and Hertz supplemented the primary texts with explanatory remarks and comments. Some of them have a general introductory character, explaining, for instance, the difference between induction and deduction or elucidating Locke’s conception of two kinds of properties; the others present useful syntheses of methodological solutions, comparing, e.g., Carnap’s or Reichenbach’s ideas with Helmholtz’s.
