Abstract

It is instructive to view the scientific revolution from the point of view of Robert Boyle’s distinction between intermediate and ultimate causes. From this point of view, the scientific revolution involved the identification of intermediate causes and their investigation by way of experiment as opposed to the specification of ultimate causes of the kind involved in the corpuscular matter theories of the mechanical philosophers. The merits of this point of view are explored in this paper by focussing on the hydrostatics of Pascal and Boyle, understood as the experimental investigation of the action of the intermediate causes weight and pressure. The distinctive features of this new science are highlighted by comparing it with two alternative versions of hydrostatics, that of Stevin and that of Descartes.
