Hobbes on the Cause of Action: How to Rethink Practical Reasoning

Abstract

Abstract In the free-will discussion between Hobbes and Bramhall, Hobbes’s principle that actions are necessary is not immediately action-theoretic. The fundamental theoretical context of Hobbes’s explanation of action lies in an understanding of causation more generally. However, Hobbes’s action theory is not simply modeled after the account of cause and effect in his First Philosophy. It introduces a temporal qualification which ranks necessitarianism higher than First Philosophy does: not only a voluntary action, but also the determinate moment when the mental act of volition is formed, is necessitated. My paper argues that this strengthening of causal necessity is due to the Hobbesian scheme of deliberation, which must be analyzed in terms of one distinctive kind of ‘mental discourse’ and practical reasoning, not merely in terms of a series of passions. For Hobbes, the impossibility of a direct representation of the future requires the mediation of a mental construction.
