Russellian panpsychism, the view that concrete reality is entirely physical and fundamental physical entities are intrinsically experiential, is faced with the combination problem – the challenge of explaining how the experiences of microphysical entities combine to form the experiences of macro-physical entities such as humans. While such combination is deemed impossible by critics of panpsychism, a ‘Leibnizian’ response to the problem – that microphysical (and micro-experiential) entities never combine – has received little attention. This paper seeks to evaluate the viability (...) of such a Leibnizian panpsychism. After motivating the view, we outline and respond to two kinds of objections a critic of the view might have: (a) mereological nihilism, the view that individuals never combine, is an unviable position independent of panpsychism, (b) Leibnizian panpsychism entails the unacceptable view that human experiences are physical simples. We argue that both sets of objections can be addressed, and that Leibnizian panpsychism ought to be taken more seriously as a metaphysics of consciousness. (shrink)

Panpsychism, the view that phenomenal consciousness is possessed by all fundamental physical entities, faces an important challenge in the form of the combination problem: how do experiences of microphysical entities combine or give rise to the experiences of macrophysical entities such as human beings? An especially troubling aspect of the combination problem is the subject-summing argument, according to which the combination of subjects is not possible. In response to this argument, Goff (2016) and Miller (2017) have proposed the phenomenal bonding (...) relation, using which they seek to explain the composition of subjects. In this paper, I discuss the merits of the phenomenal bonding solution and argue that it fails to respond satisfactorily to the subject-summing argument. (shrink)

Structural realism is the view that scientific theories give us knowledge only of the structure of the unobservable world. The view faces an influential objection that was first posed by Max Newman: if our knowledge of the unobservable world were strictly limited to its structure, our knowledge turns out to be trivial, for it amounts to nothing more than knowledge of the cardinality of the world. In this paper, I shall propose a response to Newman’s objection. It shall be argued (...) that in having epistemic access to the intrinsic nature of our conscious experiences—knowledge that structural realists allow for—we have knowledge of what it is to exist as concrete phenomena. With the plausible assumption that the relations of the unobservable world are also similarly concrete, one can address Newman’s objection. I shall further contrast this response to other similar responses that have been proposed, and also address the objection that this response is not available to structural realists. (shrink)
