Abstract

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.
