Composition and plethological innocence

Abstract According to Composition as Identity (CAI), a whole is distinct from each of its parts individually, but identical all them taken together. It sometimes claimed that, if you accept CAI, then your belief in ‘ontologically innocent’ with respect parts. This claim false. But the defender CAI can different advantage for her view. Following Agustín Rayo, I distinguish ontology (which concerns what there is) plethology are). show that allows us introduce an interesting notion ‘plethological innocence’ which would otherwise collapse into ‘ontological innocence’, and renders composite objects plethologically (but not ontologically) innocent.
