Saint thomas aquinas's theory of individuation by matter presents two main problems: firstly the exact meaning of the affirmation "matter is the principle of individuation", and secondly the consistency with which he held to the same interpretation of this statement throughout his works. A third question concerns the relevance of this theory today. The author argues: firstly, that there are two aspects of individuation by matter - the metaphysical aspect assured by prime matter, and the physical aspect assured by "interminate dimensions" or their synonym "dimensive quantity"; secondly, that this interpretation remained the consist teaching of saint thomas throughout his career, and thirdly, since both modern science and the main branches of modern philosophy have failed to offer any satisfactory metaphysical explanation of reality, that the "moderate realism taught by saint thomas can provide the adequate explanation that is lacking today. Since the theory of individuation of physical beings by their matter is a key tenet of this moderate realism, it is defended as being as relevant and necessary today as is the philosophical system inwhich it is embedded.
