Abstract

A proper and rigorous analysis of the implications of a physicalist and reductionist concept of the mental (that is, that the mind is merely the activity of the human brain, and that the human brain is the contingent, provisional result of biological evolution) leads to several consequences that seem to have been overlooked so far. First of all, there emerges a case in favour of the existence of incommensurable conceptual schemes; secondly, the necessary nature of thought experiments on mind is put into question. The further exploration of the consequences of physicalism on the necessity of logical laws does not embrace the radical critics of the naturalistic approach by A. Plantinga, whose “evolutionary argument against naturalism” has only some analogies with the one exposed here.
