Abstract
Physicalism dominated Anglo‐American philosophy in the latter half of the twentieth century, and is perhaps still the most popular view among analytic philosophers. Panpsychism is increasingly being seen as a serious option, both for explaining consciousness and for providing a satisfactory theory of the natural world. Perhaps the most popular form of panpsychism at present is constitutive panpsychism. At least some fundamental material entities are conscious; facts about human and animal consciousness are grounded in facts about the consciousness of their fundamental material parts. This chapter equates panpsychism with constitutive panpsychism. In considering responses to the notorious combination problem for panpsychism, the chapter moves onto other forms of panpsychism to examine whether they fare any better against this challenge. It adopts the via negativa definition of physicalism. Panqualityism is the only form of panprotopsychism which offers a clear positive proposal as to what protophenomenal properties are.
