I am not sure why philosophical argument is needed.Ideas and minds are not known to exist without physical brains to house them. To suggest otherwise requires either evidence or a solid philosophical argument.
Anyway, some near death experiences might have shown minds exists beyond physical body. A lot of people who has NDE find themselves 'fly' above themselves, sometimes observe objects that can't be seen in their position. The problem is not much acdamic interest in NDE so it is very hard to verify.
