Historians of science interpret Cartesian physics as being either a complet
ely misguided theory, or at best a coherent metaphysical system. For this r
eason, its significance for the emergence of modern science is usually marg
inalized. The aim of this paper is to question this evaluation. The author
intends to demonstrate that despite the many practical errors and the clear
ly metaphysical ideas present in Cartesian physics, the theory is indeed a
scientific one, and it was of decisive importance for the emergence of Mode
rn Age science. The author's view is based on the intentional interpretatio
n of the emergence of modem science as a programme for the mathematization
of nature, which Husserl put forth in his Krisis. The author attempts to sh
ow that Cartesian physics were not metaphysical physics, but rather mathema
tical physics, even despite the verbal means of presentation. Thus this the
ory represented a transitional stage in the process of the idealization of
nature, a bridge between Galileo and Newton.
