Abstract:
Abstract entities have long been viewed as entities that lack causal powers; that is, they cannot be constitutive of causes or effects. This thesis aims to reject this claim and argue that abstract objects are indeed part of the causal order. I will call this thesis ‘AOCO’ for short. In the first chapter I argue that other philosophers have committed themselves to the claim that some abstract objects have been caused to come into existence. In the second chapter, I argue that the best solution to Benacerraf’s problem is to concede that abstract objects have a causal influence on what we believe. In the third chapter I examine and evaluate objections to AOCO.
