The most famous outcome of his inquiries is the law known as Webers or Fechners law which may be expressed as follows: In order that the intensity of a sensation may increase in arithmetical progression, the stimulus must increase in geometrical progression. Die innere Seite der Natur: Gustav Theodor Fechners wissenschaftlich-philosophische Weltauffassung (Philosophische Abhandlungen, Band 60), Klostermann, Frankfurt am Main. Robert H. Wozniak’s Introduction to . Gustav Fechner is widely respected as a founding father of experimental psychology and psychophysics but fewer know of his interests and work in empirical aesthetics.
