Contributions to the Analysis of the Sensations

Insisting that sensation constitutes the data for all science, physical and psychological, Mach articulated an early form of scientific positivism that provided Külpe and Titchener with an epistemological framework for their emerging views. Conceiving of space and time not as Kantian categories but as the immediate data of experience, Mach also helped lay the groundwork for the gestaltists' later recognition of the phenomenal status of extension and duration.
