IEP on Descartes' 6th meditation says
how can Descartes make a legitimate inference from his independent understanding of mind and body as completely different things to their independent existence... there is no doubt about this possibility for Descartes and given the fact that God is all powerful... the power of God makes Descartes’ perceived logical possibility of minds existing without bodies into a metaphysical possibility. As a result, minds without bodies and bodies without minds would require nothing besides God’s concurrence to exist and, therefore, they are two really distinct substances.
Can there be no minds without bodies if there is no God? Or can there be minds without bodies and no God?
What do philosophers who critically study Descartes say about this question, which seems to be an argument for God (as it appears in the IEP)?
