Dion is a human person, Lefty is his left foot, and Theon is Lefty-Complement, a proper part of Dion. Lefty is annihilated and Dion survives left-footless. After Lefty’s annihilation Theon, if he survives, occupies the same region as Dion. I suggest that this scenario be understood as a fusion case in which Dion and Theon, initially overlapping but distinct, are identical after Lefty’s annihilation and propose an account of proper names that allows us to say that Dion and Theon have (...) ‘become identical’ without commitment to occasional identity or other controversial metaphysical doctrines. The proposed solution employs the semantics developed by Wolfgang Schwarz to address the ‘paradox of occasional identity’, posed by puzzle cases of fission, to deal with the problem of Dion and Theon, a body-minus puzzle.

Are grounding claims fully general in character? If an object a is F in virtue of being G, does it follow that anything that’s G is F for that reason? According to the thesis of Weak Formality, the answer here is ‘yes’. In this paper, however, I argue that there is philosophical utility in rejecting this thesis. More exactly, I argue that two currently unresolved problems in contemporary metaphysics can be dealt with if we hold that there can be cases (...) of ‘kind-dependent grounding’, the key thought being that once we allow for such cases, we must also accept that Weak Formality is false.

sProblems about the nature of integral parts and wholes were central to twelfth-century discussions of the individuation and persistence over time of both substances and artifacts. This paper examines in detail Abaelard’s contribution to these discussions arguing that Abaelard proposes a solution to these problems which preserves our common sense intuitions about identity over time. In Abaelard’s work we find an explicit solution to the problem of the identity over time of living things which appeals to the persistence of the (...) vegetative soul through the loss or addition of corporeal matter. In work from the school of the Montani we apparently also have an account of Abaelard’s solution to the problem of the identity over time of artifacts which distinguishes between the role of a part in an integral whole and the material which plays that role such that the role persists when the matter is replaced.
