Introduction: The Primacy of Impetus

  • Michael Elazar
Part of the Boston Studies in the Philosophy of Science book series (BSPS, volume 288)


This is the introductory chapter to Part I, which analyzes the essentials of Fabri’s philosophy of motion. This chapter presents the key role of impetus within Fabri’s basic physical thinking. The concept of impetus, which was introduced by scholastic philosophers in order to explain projectile motion and natural acceleration of falling bodies (the two phenomena which standard Aristotelian physics had found difficult to cope with), was seen by Fabri as a concept on which “not only motion itself but also the whole of physics” depends. Afterwards Fabri’s “physical credo” is briefly compared with Aristotle’s and initially contextualized vis-à-vis contemporary general views.
