Abstract
Contemporary thinkers who address the problem of causal relations generally favor Hume’s analysis, although some periodically manifest interest in Aristotle’s exposition as an important and viable alternative. Few, however, find among the many philosophers who came between Aristotle and Hume any worthwhile contributor to the development of this problematic. Some might note, for example, Nicholas of Autrecourt as a medieval precursor of Hume, but this merely keeps the discussion fluctuating between the same two poles. This essay aims to call attention to a different and intermediate view, not hitherto noted, that was proposed in the High Middle Ages by Thomas Aquinas. It argues that Aquinas made a significant advance beyond Aristotle in his analysis of antecedent causation, and thereby made possible the certification of some elements in Hume’s analysis, without subscribing to its more extreme results. In so doing, moreover, Aquinas adumbrated some problems in contemporary analytic discussions of the causal relationships between events, and consequently may shed light on their solution.
