According to philosopher Harold Noonan:
- The most influential part of Wiggins's work has been in metaphysics, where he has developed a fundamentally Aristotelian conception of substance, enriched by insights drawn from Putnam (1975) and Kripke (1980). His works also contain influential discussions of the problem of personal identity, which Wiggins elucidates via a conception that he calls the "Animal Attribute View."
