Abstract
Many of us think that ordinary objects – such as tables and chairs – exist. We also think that
ordinary objects have parts: my chair has a seat and some legs as parts, for example. But once we
are committed to the (seemingly innocuous) thesis that ordinary objects are composed of parts, we
then open ourselves up to a whole host of philosophical problems, most of which center on what
exactly the composition relation is. Composition as Identity (CI) is the view that the composition
relation is the identity relation. While such a view has some advantages, there are many arguments
against it. In this essay, I will briefly canvass three different varieties of Composition as Identity,
and suggest why one of them should be preferred over the others. Then I will outline several versions of the most common objection against CI. I will suggest how a CI theorist can respond to
these charges by maintaining that some of the arguments are invalid. (In part 2, I show how a CI
theorist can maintain that the remaining arguments, while valid, are unsound).
