The author presents an autobiographical story of serious peripheral motor nerve damage resulting from chemotoxicity induced as a side effect of Hodgkin’s Lymphoma treatment. The first-person, phenomenological account of the condition naturally leads to philosophical questions about consciousness, felt presence of oneself all over and within one’s body, and the felt constitutiveness of peripheral processes to one’s mental life. The first-person data only fit well with a philosophical approach to the mind that takes peripheral, bodily events and states at their face value, and not as a body-in-the-brain, which has been popular with most neuroscientists. Thus the philosophical tradition that comes closest to the idea of the peripheral mind is Maurice Merleau-Ponty’s bodily phenomenology.

This paper proposes a new line of attack on the conceivability argument for mind-body property dualism, based on the causal account of properties, according to which properties have their conditional powers essentially. It is argued that the epistemic possibility of physical but not phenomenal duplicates of actuality is identical to a metaphysical possibility, but irrelevant for establishing the falsity of physicalism. The proposed attack is in many ways inspired by a standard, broadly Kripkean approach to epistemic and metaphysical modality.

Mainstream metaphysics has been preoccupied by inquiring into the nature of major kinds of entities, like objects, properties and events, while avoiding minor entities, like shadows or holes. However, one might want to hope that dealing with such minor entities could be profitable for even solving puzzles about major entities. I propose a new ontological puzzle, the Shadow of Constitution Puzzle, incorporating the old puzzle of material constitution, with shadows in the role of the minor entity to guide our approach to the issues involved. I then analyze the standard answers to the original puzzle of constitution, in their role as potential solutions to the new puzzle. Finally, I discuss three views that can solve the proposed puzzle.

Roy Sorensen’s adventure in Shadowland started with his prize-winning article, "Seeing Intersecting Eclipses" (published in The Journal of Philosophy, and chosen by the board of the Philosopher’s Annual as one of the ten best philosophy articles of 1999), which is the basis for the first two chapters in this book. The recipe adopted in that article is followed in most of the following thirteen chapters, five of them being based on Sorensen’s previous articles on the topic: start with an open mind regarding the existence and causal efficacy of absences, shadows, i.e. absences of light, in our case, devise a riddle involving perception of such absences, and draw the consequences for the philosophy of perception and/or ontology.
