 It can be argued that none of the traditional neutral monists accept (3). All of them would agree that neutral entities can be a constituent of both physical and mental non-basic entities. But it is doubtful whether any of them would agree that the fact that a basic entity can be a constituent of both physical and mental non-basic entities is sufficient to make it neutral. For it is conceivable that a basic entity that fails to be neutral (according to (1), the Neither View) should figure in the construction of both physical and mental non-basic entities.
