Defeasibly Sufficient Reason

My aim is to show that supervenience claims follow from instances of a principle I call the principle of defeasibly sufficient reason. This principle construes the completeness of physics quite differently from strong or reductive physicalism and encodes both scientific and common sense patterns of explanation and justification. Rather than thoroughly defending the principle in the short space of this paper, I will sketch how one might defend it and a resulting fainthearted physicalism.
