Reply #17: If determinism is true,

[Stunster]

then whether you believe in determinism or not is itself determined. Rational argument about whether determinism is true would just be one of the causal factors involved (and maybe not even a significant one, or at least not the most important). In which case, there are rational worries about whether belief in determinism can ever be rationally justified, since justification seems to be a different kind of relation from that of deterministic (and especially material) causation.

For a nice presentation of some of these worries, go http://www.infidels.org/library/modern/victor_reppert/reason.html">here.
