Federik Grisogono (Federicus Chrysogonus) and the Notion of Useful Theoretical Science

The article considers the idea of astronomy as useful theoretical science as it was promoted by Federik Grisogono, Croatian renaissance philosopher, astrologist and physician in his work Astronomical Mirror. U ntill the Renaissance, theoretical science in principle could not be useful since this followed from the very aristotelian-platonic notion of theoretical science whose assignment was only to consider what is eternal and unchangeable. Theoretical science in any case could not be “useful science”. Grisogono considers possibility of a theoretical science – mathematics (i.e. astrology) – being the highest theoretical and at the same time useful science. For us, of course, astrology is none of this. However, by means of his groundbreaking notion of theoretical science, Grisogono worked towards suspending the traditional notion of the theoretical science, as well as towards opening of new possibilities of establishing the modern idea of science.
