 The last point cuts both ways. Why not say that different complex objects can have the same parts? Armstrong (1997: 118) answered this question positively and argued that facts are non-mereological composites. Lewis has denied that there is room for non-mereological composition (see Lewis 1992: 213; for discussion McDaniel 2009). However, independently of considerations about states of affairs we allow for different wholes that share all their parts. For instance, the sentences “John loves Mary” and “Mary loves John” both consist of the same words “John”, “Mary” and “loves”, yet they are clearly different sentences.
