 Second, the language of constitution is more natural if the situation is described in some ways rather than others. It is natural to say that the statue is made of clay or even from a piece of clay. But suppose one characterises the clay more exactly, in terms of the particular atoms in a particular arrangement. Strictly, on modal grounds, this structured collection and the statue are different. The statue could have been made of a collection of atoms with at least some different members, but the entity defined as containing just those atoms could not. This entity—atoms A1…An in given spatial arrangement S—is not a very natural kind of object, but it is a real body, in a way that something arbitrarily composed of, for example, half of this table and two toes from President Bush’s left foot is not. This collection of atoms in this structure is what investigation would show to be really there. Though it is natural to say that the statue is constituted by the atoms, it is less natural to say that the atoms and the structure taken together, are what it is made from: rather it might seem natural to say that that is what it is. To use the Aristotelian terminology, there is strong pressure to say that atoms and structure together are matter and form, and hence are the complete individual.
