Compatibilism,determinism, and the identity theory

Two issues are raised with regard to Ted Honderich's A Theory of Determinism. First, regarding the relation between a token identity theory of mental and physical events and Honderich's ‘psychoneural union theory’, it is suggested that a token identity theory would serve Honderich's purposes while securing a simpler ontology. Second, it is argued that there is a substantive philosophical issue dividing compatibilists and incompatibilists on the question of whether persons possess free will, contrary to Honderich's contention that the compatibilist and incompatibilist differ only in responsive attitude.
