Abstract
The work of Hussefl and Freud had common sources in the philosophy,
psychology and physiology of the nineteenth century. Herbart, Brentano,
Helmholtz, Fechner, Wundt and Mach were among the towering figures in
their common background who had influence on their respective work. 1
Although contemporaries who had little concern for the other's professional
interest, Husserl and Freud nevertheless struggled with some common
problems. One of these is the relationship of sensation to memory and to the
experience of time. The concepts of sensation, memory and time were, in
fact, artifacts which the empirical methods of nerve-physiology, the
psychophysical testing of sensory thresholds, as well as the metaphysics
and positivism of the late nineteenth century had left them.
