135Stoljar’s Dilemma and Three Conceptions of the Physical: A Defence of the Via NegativaErkenntnis 81 (2): 201-229. 2016.Physicalism is the thesis that everything is physical. But what does it mean to say that everything is physical? Daniel Stoljar has recently argued that no account of the physical is available which allows for a formulation of physicalism that is both possibly true and deserving of the name. As against this claim, I argue that a version of the via negativa—roughly, the view that the physical is to be characterised in terms of the nonmental—provides just such an account.
