Hi Gus, thanks for the chart you provided. I find fault with argument that its advancing. I think you are arguing something along these lines:
1. Beliefs or noetic attitudes need adequate epistemic justification.
2. If beliefs or noetic attitudes need adequate epistemic justification, then faith in the belief ‘God exists’ needs adequate epistemic justification.
3. If faith in the belief ‘God exists’ needs adequate epistemic justification, then the only means in which faith could be epistemically justified is if it appeals to the belief that God exists.
4. If the only means in which faith could be epistemically justified is if it appeals to the belief that God exists, then appeals to faith ultimately lead to circular arguments.
5. If appeals to faith ultimately lead to circular arguments, then appeals to faith should be rejected.
6. Therefore, appeals to faith should be rejected.
My contention with this argument is premise three. As a theist, I agree that faith should be buttressed by some justification and that blind faith is something to be avoided. However, why should one believe that the consequent is the case for faith? The mature theist, I would suppose, does have other means in which to justify her faith. She could appeal to the intuition that God exists, the arguments for God’s existence, testimony from other intelligent/reflective believers and the failure of naturalism to adequately explain the totality of existence as means of justification. The above items are far from simple appeals to some prior and seemingly unjustified belief as premise four suggests. However, even if one grants premise three, the argument still does not seem to succeed, for premise five is contentious as well. Perhaps appeals to faith are circular, yet this might not give one reason to reject them since could not one argue, as the coherentist would, that any justification is eventually circular? Of course, I would qualify this response by saying that a person who appeals to faith should at least lay down all their cards that give reason, aside from faith, for why he or she believes in God. Still, if justification is circular when all is said and done, then circular arguments are inevitable. So, from the coherentist perspective, appeals to faith should not really be rejected on the grounds of circularity since this is a pernicious effect that could happen in any instance where one has to give an account of justification for one’s beliefs. The above reasons motivate my doubt for the success of your argument.
