Is There a Fallacy of Composition?

When it comes to explanation, individuals are not different from pluralities. It makes just as much sense to ask why one camera exists as it does to ask why ten cameras exist. So like color, there's no differece between parts and wholes. Just like it seems true that bray applies to the parts and to the whole, so does explanation. There maybe that's not as clear to see in terms of an explanation yat well.
