As regards systems, it is possible to show that certain axioms are false, if they lead to contradictions, ie. an internal critique. However, in order to establish the truth of one's system, and axioms, it is impossible to do so without begging the question. A system of thought then, must take this into account, and rather than ones' epistemology being purely prescriptive, it must also be descriptive. A purely prescriptive epistemology will provide means or a criteria for determining whether a proposition is true, but will not be able to justify those criterion. A purely descriptive epistemology will take it as self-contradictory to deny that we can not know anything, and will provide a developing theory which helps explain, how we do in fact have knowledge of things. The problem with this, is that we have no way of determining whether any particular proposition is true or not. This is why an epistemology must be both prescriptive and descriptive -- an epistemology properly defined, which is also self-contradictory to deny.
Like Descartes probably, I am trying to rebuild philosophy from the ground-up and for some time realize that there must be some ground to build it up from. Denying the need for ground (axiom) leads to nowhere.But still, there is still lingering feeling of hopelessness of reaching to the truth (reality, or whatever we call it).

These include the existence of the external world and the existence of other minds. We don't just arbitrarily adopt them, but we are rational in believing them based on experience. If you are trying to prove them, I would, with all sympathy to your endeavor (because I have tried), I would encourage you to give up. Descartes, I think, has been refuted on the grounds that he had no right to say "I think," because he was already assuming his own existence in doing so.
Even if you could prove basic beliefs, I think any argument for them would be less obvious than the basic beliefs themselves, and so to tell someone to believe based on your argument would be to tell them to put their basic beliefs on less solid grounds than they already were.
Yet we do not believe in, say, other minds, on the basis of experience. Rather, we believe it based on, as I suggest, a habit of our species.
So in this case our hand is free. We can hold ourselves to a higher epistemic standard if we wish. If we want to minimize our beliefs for which we have no reasoned support, then the existence of God is a perfect candidate for expulsion.

I am far more sure that God exists than that the external world exists. I subject my belief to all questions and it comes out like gold. This is what its like when you have a real, solid relationship with Jesus Christ.
On your view, there doesn't seem to be any reason to rationally accept that other minds exist or that the external world is real. If everything you believes comes through your senses, how do you justify rationally trusting your senses? If you cannot even justify that, anything else you say is suspect given its all based on things you deduce from your sense experience during your life.
You may wish to re-read my last post: Giving up my belief that other minds exist isn't an option. And since that is the case, it seems inappropriate to call it irrational.

I'd be very curious to know what are your reasons for believing in God. I remember that when you first came here you expressed frustration at having not been taken seriously at richarddawkins.net when you argued for the existence of God. I'm sympathetic to that, and look forward to giving you a more careful and reflective response to your arguments, whatever they happen to be. But as far as I have noticed, you have yet to present any. If you ever feel like doing so in the future, I would be happy to discuss them.
I'm not entirely clear on what you mean by "trusting [the] senses." Are you questioning the rationality of inductively inferring conclusions based on our sense data? In a certain sense, using induction is part of what it means to be rational. But beyond that, we simply must use induction in conjunction with our sensations and other experiences. Again, we just haven't any choice in the matter. That we can't present any non-inductive (and hence non-circular) argument to trust induction makes no difference. We will use induction, and we had better be reconciled to that fact.(emphasis added)
But I should stress that this situation is universal. It doesn't go away once you decide to believe in God. None of us can rationally justify trusting our senses except to point out that trusting our senses is part of what being rational means. Fortunately we don't need more than that.

My reasons for believing are not arguments, though I do not take a leap of faith (like I think you do with trusting your sense experience)... though Dr. Craig's arguments seem good to me. If you are looking for arguments I would refer you to his. If you want to read my personal reasons for believing God, I have written at length about it on other threads and I can link you to that.
You have no logical reason. You admit you have no non-circular argument to trust induction. Saying "I can't help it, I have no choice" is not a logical reason to accept the proposition, "my senses give me true beliefs." Its just saying you are forced to accept it without a logical reason.
Philosophers have taken this question seriously for ages and you just avoid it by defining the problem away. As you admit, there is no non-circular reason for you to trust your senses. You simply take it by blind faith--whatever you define rational as, this is certian. If you have reason to believe in a good God, the only reason isn't nothing. I think you would have reason to believe that God would not deceive you, and so give you trustworthy sense experience.

Quite so. But I suggest that this is a reasonable thing to do in this case. Reason cannot justify itself beyond being consistent. So when we look to the foundations of reason, as it were, we ought not be surprised when we cannot justify them on more primitive grounds.

Why does this descend into the argument for the existence of God? If we can not claim a reliable epistemological foundation, how can we start off to anything?

You make the statement that the theist has good reason to think his sense are reliable and the atheist has none, and then you ask why this descends into an argument over the existence of God? But, actually, I nowhere argued either that God exists or that he does not.
But I think that I do not need to assume God to have a warranted belief in the basic reliability of my senses. Why? Because they have proven to be reliable, when I feel my hand burning I pull it away as a reflex. But I know that that sense and reflex is reliable for protecting me from burning my hand. When I look outside and see it is pitch dark and reason that it can't be midday, I have found every single time that, in fact it was not midday. Now, I will wander a bit further away from what I know, but I think it is very reasonable to believe that it is at least possible that nature through evolution has endowed me with remarkably reliable senses and basic reasoning abilities.
I don't know that the way that I know that when it is pitch black out it is not midday, I won't call it knowledge, but reasonable belief. To seriously doubt the possibility of such is IMO to take 'brain in a vat', Zhuangzi's butterfly dream and other such skeptical thought experiments all too seriously.Every single system of truth claims including science have its counterargument. I agree that "I think therefore I am" is fallacious, it puts the cart before the horse. "I am therefore I think" is a better start. After that, how can we go from...I am.
The more abstract the truth claims the more I am likely to doubt them. I think that is a rational principle. By the time you get as abstract as to try and imagine the nature of an eternal uncaused cause, I think it is reaonable to believe that that is exactly the kind of truth claim that may just require an unreachable level of justification. That is why I believe, but do not know that there is no knowledge of the metaphysical. Beliefs about it may be more or less reasonable, some may even be true, but none that I know reach the level of knowledge. Do I believe there is external world? I guess I do. Can I justify it? In the manner of the most skeptical epistemology, no I cannot. Philosophically, we are all stuck here and wonder whether we can move on. Furthermore, if indeed we can justify it... Is it objectively true? Or is there even such a thing as objectively true? What is wrong with being self-refuting? And all that. Sigh...
I'd say forget the most skeptical epistemologies, they serve little purpose but perhaps to keep us from getting too big for our britches. You can have a very reasonable faith in the power of science to tell us a good great deal about objective, physical reality. Maybe, lets say it is innocent of being nonsense until proven guilty. If you believe that the intelligibility of the universe is proof of God, I don't think that is an unreasonable belief. However, I don't think it rises to the level of probabilty of being true to warrant as knowledge.
That is, OK, because besides objective reality, there is the even more interesting, meaningful but tricky realm of subjective reality. In this realm there may be no knowledge, but that leaves it wide and hospitable to belief and faith.
Hi People,It is not only axioms at the root of worldviews, but perceptions of axioms. The same words mean something different to different people, especially in cases of metaphysics. It is because of these different perceptions that the axioms cannot be brought into harmony by logical reasoning. Whatever you say, the person is going to see what they want to see.
I have read a fair amount of philosophy books and now quite worried about the possibility of us arriving at truth/reality (or whatever you termed it) through philosophy or any method of inquiry. The problem is that all philosophy or knowledge rests on central axiom which we must take to be self-evidently true. This is the part that concerns me. I have recently encountered websites by ex(?)-philosopher who regarded most philosophy as BS (he also considers natural philosophy (science) as BS) and suggests that if we accept any axiom, we can believe in anything consistently including solipsism which he claims irrefutable although crazy to hold. What is your take on this?
It is no good to argue that "you use philosophy to argue for this", I am not arguing for truth of my statement, in fact, I do not wish to argue at all. I want to know truth as simple as that.
