Abstract

Discussions about physicalism, reduction, special sciences, the layered image of reality, multiple realizability, emergence, downward causation, etc., typically make the ontological presupposition that there is no room for new properties in the physical world. The domain of physical properties would thus have been established once and for all. It is my purpose in this paper to explore the alternative hypothesis that there can be, and that in fact there are, new physical properties. In the first section, I propose a brief analysis of the notions of property, physical property, and new physical property. In the second section, I present four general situations in which it would be plausible to speak of the existence of new physical properties. All of this is used to evaluate the content and scope of the hypothesis of physical novelty. Lastly, I examine certain interesting consequences of such a physical novelty in relation to some of the above mentioned topics.
