Abstract

In common with other forms of nonreductive materialism, emergent materialism of this sort is accused of trying to have its cake and eat it. Ontological physicalism, it is said, necessarily implies reductionism which rules out the idea that there are irreducible emergent mental properties and laws. For according to such physicalism, everything is composed of physical constituents whose behaviour is governed by the laws of physics and mechanics. It follows that, in theory at least, every particular mental process is describable and explainable in purely physical terms, without recourse to mental descriptions. Description in terms of emergent properties and laws seems superfluous. Nothing save the complexity of the task prevents us from describing and explaining everything that exists or happens in purely physical terms.
