ABSTRACT:
The development of scientific psychology has been largely influenced by the Kantian thought. While in its early years he maintained a psychology as a knowledge of the human soul, not far from the positions of Wolff and Baumgarten, after his critical turnpoint he strongly critiziced the substantial soul on theoretical grounds, and denied to psychology the status of a science, although he recovered that idea through the needs of the practical reason.
He also paved the way not only for a fenomenistic approach to the mind, but also for a biased interpretation of the a priori structures of the mind, then conceived as physiological structures that would permit the construction of a physiological psychology like the Wundtian one.
