Well, I just don't see a need for believing anything. I operate very well with only provisional hypotheses. But as I said, it's a difficult condition to acheive - believing nothing. In actual existential fact, it is more of an ongoing process - of negation.
As far as meaning goes, I don't see any necessary connection between belief and meaning. Many of my provisional hypotheses mean a great deal to me...
So as not to go too far off topic here, here's a thread where this is discussed further.
