ABSTRACT
In this chapter, the author offers two additional arguments in favor of Substantial Priority—what he call the terminus argument and the tracking argument. The author attempts to explore the interrelationship between issues in fundamental mereology and the metaphysics of mind and free will. The chapter explores how Substantial Priority is uniquely positioned to carve out important dialectical space concerning debates in the metaphysics of mind and human persons. It aims to underscore how Substantial Priority as a neo-Aristotelian fundamental mereology bears on one aspect of personal ontology, in particular how it opens up dialectical space for materialist and hylomorphic views of the human person. Substantial Priority, when conjoined with SUB-Thinker, offers the stand-alone maximality response the needed grounds to infer that the brain itself cannot think, and ipso facto cannot think the human animal's thoughts.
