Born on this day — a true gentleman in every sense. If ever Wiggins was miffed that I preferred to talk to him about his metaphysics rather than his ethics, he never let on. Sameness and Substance Renewed (2001) and its two precursors, 1967’s Identity and Spatio-Temporal Continuity and 1980’s Sameness and Substance, jointly remain one of my favourite reads. See discussion of Wiggins’ sortal identity at the Information Philosopher.
