Abstract
Causality is without doubt one of the main topics of Hobbes's philosophy. Quite justifiably, F. Brandt stated that Chapters 9 and 10 of De Corpore, which expound Hobbes's doctrine of causality, are the most crucial ones ever written by Hobbes. According to Hobbes the quest for causes is the quintessence of all philosophical inquiry. "Philosophy is such knowledge of effects or appearances, as we acquire by true ratiocination from the knowledge we have first of their causes or generation. And again, of such causes or generations as may be from knowing first their effects." Although this definition as such is quite peculiar and fraught with difficulties, the description of philosophy in terms of causal knowledge is in itself rather traditional. Hobbes himself admits that he follows the Aristotelian dictum scire est per causas scire. However, although Hobbes agrees with the Aristotelians that knowledge bears a causal character, he fundamentally disagrees with them as to "what he saw to be genuinely causative." Hobbes's doctrine of causes may be seen as a systematic attempt to discard the scholastic view on causality and replace it with strict mechanistic explanatory principles. Therefore, Hobbes's theory of causality can only be understood properly if we put it against its scholastic background, which is the line of interpretation followed in the present article. It will be made clear that Hobbes's relation to scholasticism is rather complex, ranging from downright rejection to the adoption of terminological distinctions as well as of specific arguments and doctrines.
