I'll try to answer this...
I am a supreme advocate of logic. Science, for example, requires logic. I tend to believe well-tested scientific propostions. I require lots of evidence that scientfic propositions are true. That's one reason why I think string theory is just speculative metaphysics - there is not one shred of evidence to support it.
But if one keeps demanding reasons, if one keeps asking 'why' something is true, then one eventually gets to some ground level propositions that I cannot prove by means of logic. Somethings are ridiculous to question like "how i know that I am not crazy?'.
I think we are on the same page so far...
So, for most of what I believe, I demand exacting evidence. In fact, I demand evidence in every case where evidence is
possible. But, again, when I push the questions back far enough I run into a wall - there are some deep ground level propostions that seem impossible to prove and where the domain of evidence and reason does not extend. for example, the following propostions seem to be impossible to prove:
(1) The principle of suffifient reason
(2) Objects exist when not being percieved
(3) Our minds grasp reality
(4) The future will resemble the past
(5) I am not crazy
Now, I would love really love to be able to prove these propostions are true, but, after many years of sincere reflection, I find that I cannot. And yet, I seem believe them anyway. Somethings I can't prove to be true but seem absured to doubt and I am unable to disbelieve anyway. And what is more, I must accept these propostions as true in order to prove the truths of science and expose theism as falsely grounded.
These propostions strike me as pre-requisites to being rational and so naturally stand outside the possibility of proofs.
You might say that these propositions are absurd to doubt.
I agree. But then, like a good rationalist I look inisde myself and ask if I can prove it. The answer is No. Thus, I seem to be just trusting my brain to supply a foundation for rational discourse.
Now, you tell me whether that is an upper case "F" or a lower case "f".
But those few propositions are the only ones I accept on trust (or faith). And I take them on trust begrudgingly.
But I have found that what appeared to be a huge concession, is really not much of a concession at all. In fact, I think the rationalist gains more credibility by being honest about the limitations of logic than trying to make logic appear to have unlimited godlike powers.
