## Abstract

The paper presents, motivates, critiques, and proposes revisions to Baker’s Constitution View, which includes her definitions of constitution, derivative features, and numerical sameness. The paper argues that Baker should add a mereological clause to her definition of constitution in order to avoid various counterexamples.

## Notes

See Rea (1995) for the original formulation of the problem of material constitution, which consists of five assumptions: (1) The Existence Assumption (Some

*x*s compose something at*t*), (2) The Essentialist Assumption (If the*x*s compose*y*at*t*, they compose something at*t*that essentially bears*R*to any parts it has at any time), (3) The Principle of Alternative Compositional Possibilities (If the*x*s compose*y*at*t*, they compose something at t that doesn’t essentially bear*R*to any parts it has at any time), (4) The Identity Assumption (If the*x*s compose*y*at*t*and the*x*s compose*z*at*t*, then*y*=*z*), and (5) The Necessity Assumption (If*x*=*y*, they are essentially identical).The indiscernibility of identicals says this: ∀

*x*∀*y*(*x*=*y*→(Fx→Fy)).The converse of a relation Rxy is the relation Ryx. The disjunction of two relations Rxy and Sxy is the relation RxyvSxy. So the disjunction of a relation Rxy and its converse is the relation RxyvRyx.

Throughout the paper, when I can, I simplify the definition.

Throughout the paper, when I can, I drop the reference to time.

A branching case of constitution is any case of constitution where

*x*constitutes*y*and*z*, neither*y*nor*z*is identical to the other, and neither*y*nor*z*constitutes the other.An equivalence relation is any relation that is symmetric, transitive, and reflexive. A relation

*R*is symmetric iff (i.e., if and only if) ∀*x*∀*y*(Rxy→Ryx) and is transitive iff ∀*x*∀*y*∀*z*((Rxy&Ryz)→Rxz). A relation*R*is reflexive iff ∀xRxx and partially reflexive iff ∀*x*∀*y*((RxyvRyx)→Rxx). Every relation that is symmetric and transitive is partially reflexive and so is a partial equivalence relation. But not every relation that is symmetric and transitive is reflexive. So not every relation that is symmetric and transitive is an equivalence relation.The ancestral of a relation Rxy is the relation: Rxy or there is z

_{1}, z_{2}, …, z_{n}such that Rxz_{1}, Rz_{1}z_{2}, …, Rz_{n}y.Baker 2000, pp.99–101 extends the definition of having a feature derivatively so as to include hybrid features. I ignore the extension here.

Translate this:

*x*doesn’t have*H*at*t*independently of*x*’s c-relations to*y*at*t*.A stacking case of constitution is any case of constitution where

*x*constitutes*y*and*y*constitutes*z*.It also seems Lump should be a statue independently of its c-relations to Pot. But, on (I), this is false for the same reason.

It also seems Statue is not a pot independently of its c-relations to Lump. But, on (I), this is false for the same reason.

It also seems Statue should be a statue independently of its c-relations to Pot. Moreover, it seems Pot should be a lump independently of its c-relations to Statue, and Statue should also be a lump independently of its c-relations to Pot. But, on (I), these claims are all false for the same reason.

It also seems Statue should be a pot derivatively. But, on (D), this is false for the same reason.

In other words, on (I), everything is not a statue independently of its c-relations to Pot. So, on (I), everything that is a statue independently of its c-relations to Pot is such that Pot is a statue independently of Pot’s c-relations to it.

Translate this: it must be that: for any F

^{★}in*G*-favorable conditions at time*t*, some G^{★}spatially coincides with it at*t*.Translate this: it could be that:

*x*exists at time*t*but no G^{★}spatially coincides with*x*at*t*.Translate the second conjunct: any G

^{★}that spatially coincides with*x*is identical to*y*.The

*x*s compose*y*iff the*x*s don’t overlap each other, each of the*x*s is a part of*y*, and each part of*y*overlaps at least one of the*x*s.Translate this: it must be that: if

*x*is in*G*-favorable conditions at time*t*, then some G^{★}materially coincides with*x*at*t*.In a

*de re*modal claim, a designator is in the scope of a modal operator or a modal operator is in the scope of a quantifier. In a*de dicto*modal claim, neither is true.A relation

*R*is asymmetric iff ∀*x*∀*y*(Rxy→∼Ryx) and is anti-symmetric iff ∀*x*∀*y*((Rxy&Ryx)→*x*=*y*).Translate this: each of the

*y*s is a mereological part of*x*, and each mereological part of*x*mereologically overlaps one of the*y*s.Translate this:

*x*is a proper mereological part of a sum that constitutes*y*at*t*.
