 Second, counterpart theory might offer an answer to certain puzzles about identity. Is a statue identical to the piece of clay from which it is formed? Is a person identical to their body? Lewis says yes. However, intuitively persons and bodies, or statues and pieces of clay, seem to differ in their modal properties: the piece of clay could survive squashing, the statue could not. According to Lewis, the explanation is that when we refer to an object as a statue, we give more weight to similarity with respect to shape than when we think of the same object as a piece of clay (see Lewis 1971; Lewis 1986e, 252ff.; Lewis 2003, 27–8; and Robinson 1982).
