Abstract

This paper is a reply to Stephen Davis' ‘A Defence of the Free Will Defence’. With the aid of some elementary modal logic, some of the inner workings of Davis’ argument are explored, and the nature of the opposition of the Davis argument to the Mackie thesis is made plainer. It is concluded herein that while the Davis argument is interesting and illuminating, it is not conclusive, as Davis appears to think, and that the burden of proof remains on the opponent of the Mackie thesis, i.e., the Free Will Defence defender
