 According to Garcia (2016), what role tropes can play in causation will depend on how we conceive of the nature of tropes. If tropes are what he calls ‘modifiers’, they do not have the character they confer, a fact that would seem to make them less suitable as causal relata.  Not so if tropes are of the module kind (and so have the character they confer). But if tropes have the character they confer, Garcia points out, we may always ask, e.g.: Is it the couch or is it the couch’s couch-shaped mass-trope that causes the indentation in the carpet? Garcia thinks we have reason to think they both do. The couch causes the indentation by courtesy, but the mass trope would have sufficed to cause it even if it had existed alone, unbundled with the couch’s other tropes. But this suggests that if tropes are of the module kind, we end up with a world that is (objectionably) systematically causally overdetermined. The role tropes play in causation may therefore be more problematic than what it might initially seem.
