A number of philosophers have recently held that the phenomenal aspect of experience cannot be adequately dealt with within a materialist account of the mind-body relation. A natural response for those who take both this objection and scientific considerations seriously is to adopt either a double-aspect theory of mind or a version of epiphenomenalism. In this paper I will examine such a view recently defended by Keith Campbell. Campbell calls his view a ‘new’ epiphenomenalism. I shall begin by considering Campbell's conception of an imitation-man, a notion which has been elsewhere employed in arguments against materialism. I shall demonstrate that Campbell is thereby committed to entertaining seriously a suspect form of causation which I have labeled "sometime-causation". I shall then proceed to argue that for this and other reasons, Campbell's ‘new’ epiphenomenalism is not clearly superior to its traditional predecessor.
