 The fact that sortals do not seem to follow the discipline that Wiggins wishes for them might be taken to support the view that substances can be individuated under much more generic notions, such as same body or same material thing (Ayers 1991a). On this view, material cohesion is what picks out paradigmatic physical things. Wiggins regards these ideas as too generic to be adequate on their own. Such a concept cannot be “understood except as determinable that has dog, horse, ball, [etc] among its determinations” (1997: 417–8).
