I think I agree with you trix, it was the amount of knowledge at the time, so my objection wasn’t (entirely) valid.
WWell there was lots wrong with descartes’ reasoning whether or not he believed in god (Cartesian bridge, Cartesian mathematics), but the only thing he got wrong in respect to religion was arguing that reality had to exist cause God wouldn’t decieve us because he could concieve of a perfect being and the only way he could do that is if there were a perfect being. Nice try though.
