Abstract

From an epistemological point of view, monopsychism implies that the unity or universality of cognition can be secured only through the unity of the subject. Scholastics in the 13–14th centuries who did not accept it for various reasons therefore had to show that the multiplicity of subjects does not impair the unity of cognition. But the attempts to harmonize the unity of cognition with the plurality of subjects were not successful. While some of them only transformed the issue into another with some variations, others accepted monopsychism to some extent.
