Michael Dummett argued that, whilst we can imagine circumstances under which agents may rationally believe themselves capable of affecting the past, the attitude of such agents is bound to seem ‘paradoxical and unnatural to us’. Therefore, only agents very unlike us could intentionally affect the past. I argue that this is not the case. I outline circumstances in which the attitude of such agents is prudent, even by our own standards. Worlds in which backwards causation occurs could, then, contain agents (...) very much like us.
