@Squid...
There's hope for you as a philosopher yet. You're on the right lines in respect of god. In fact, D thinks that he can prove god's existence rationally, but he also thinks that reason is reliable because god guarantees it. So his argument isn't mistaken quite for the reason you mention - but it is circular, and, in this case, viciously so.
