> driven by (or driving, depending on what you believe)
Belief requires free will, making "driven by" contradictory. There may be a mixture or a degree removed, but the idea that free will doesn't exist is always self-contradictory.
I haven't read parent's point, but I guess one could argue that belief requires the hability to ponder opposing views and choose one. The choice part is where free will comes in.
The word "believing" doesn't imply choice anymore, for example you can say an earthworm believes all big animals are the same just because that's how it thinks, not because it made a choice to think that way.
