 Another philosophical question Boethius explores in his discussions of the Trinity is individuation (as well as more widely the topic of parts and wholes). Unfortunately, it is not completely clear to what theory of individuation he subscribes. A quick reading of some passages would suggest that substances are indviduated by a bundle of accidents, but there are indications that Boethius may have preferred a theory of individuation by spatio-temporal position, or one different from either of these (cf. Arlig, 2009).
