This argument assumes that humans are reasonable, which even a casual 
look at history or current events should quickly dispel. Yes, we have 
some reasoning ability, but it is the minority of our thought processes.

Fodor seems to have a one-dimensional view of mentality. I'll respond by 
raising a question. Do you suppose emotions have any survival advantage?

Well duh. There's an infinite possibility of non-materialistic non-gods. 
Besides Fodor's example of Plato's forms, ghosts are another possibility.
