There appears to be many underlying assumptions and undefined terms in your above comments. How is "justified" defined? Why do you state that justification is only to be found in the realm of reason? How can you say that reason is the only way to gain knowledge?
Justification -- or epistemic justification, so we don't confuse it with other types of justification -- is an intellectual obligation to attempt to (ideally) only believe true beliefs and avoid false or random beliefs. It's a process by which beliefs are checked for internal and external consistency and it explains properly why the belief is true or at least as true as can possibly be known with the data at hand.
There's no quick 'n dirty definition of "justification" since it's the study of an entire field (epistemology) -- it's sort of like you can't define physics by just calling it a study of matter and energy.
It's important to know though that any ol' excuse someone offers for why they believe something doesn't count as justification. It's more specific than that. Fallacies can never justify, nor can randomness -- an example I use often is to point out that if you didn't know the capitol of Missouri so you flipped a coin, announcing that if it landed heads up then the capitol is Jefferson City... and then it landed heads up, causing you to believe the capitol of Missouri is Jefferson City... then you would have a
true belief, but not a
justified belief.
Justification can only be found in the realm of reason because reason is by definition the practice of checking claims for internal and external consistency; a requirement for justification. Therefore there is no justification without the use of reason.
If you can't justify without reason, then you can't have knowledge without reason. This is because knowledge is justified true belief. The difference between just holding a belief and knowing something is that you must justify the belief and it must be true. Both the justification aspect and the truth aspect require reason to discern -- justification for obvious reasons, but truth also because you can't know if something is true or not without checking its consistency (which is, by definition, reason).
Thus, reason is the
only way to knowledge.
I disagree. How is it we come to know to begin with the definition of the words and concepts being described? Let's take the anayltic argument of God and suffering as an example, one you have brought up more than once in the forums here. How is it that one can even make a comparison between the two concepts unless they have experienced through one or more of their senses the concept of suffering?
Interestingly, suffering is actually a qualia. Furthermore I'm not sure what you're trying to argue here. Should we doubt what our senses are telling us?
How is it one can come to the understanding of a god unless it be compared to other concepts and objects which have been previously experienced by the reasoner? I realize I am going out on a limb in disagreeing with philosophers much more intelligent than I, but I simply disagree with the belief that the definitions of various objects and concepts we have in our minds were not at some point first filtered through at least one of our natural senses.
Only those regarding empirical things, though. For instance the entirety of mathematics can emerge from a mind that doesn't even have an empirical world to sense since the null set Ø, if conceived (or even if not conceived, at that) begets the existence of all the rest of mathematics -- and Ø exists even in the absence of the physical world.
I would also point out that anayltical reasoning would not be able to determine the truth or falsehood of claims of a historic nature from a religion. For example, one would need to argue from synthetic reasoning rather than anayltic in order to attempt to refute the claim from a professed eyewitness of a resurrected Jesus.
I wasn't saying that analytical reasoning is our only tool, just one of them.
Of course we would look to empirical evidence for historical claims.
Again, how is justified being defined? What critera would you use to determine if a religious claim is justified or not?
That it isn't fallacious, that it provides warrant, and that it's internally and externally consistent. All fallacies come down to
ignoratio elenchi, or "ignorance of refutation" which actually on a deeper level just means ignorance of reason.
The belief or unbelief in something that exists outside of our natural senses is ultimately a matter of faith. This does not mean that there may not be good reasons to believe or disbelieve, but simply that at the end of the day the belief one way or the other is taken on faith. Skeptism and unbelief in something is not a neutral position.
No, it's not at all a matter of faith to doubt an unjustified proposition. It's the theists who carry the onus of proof -- if they fail, atheists are 100% justified in non-belief; which is not faith. Also, this is where analytical reasoning comes into play because there are some gods which can't exist (because they aren't gods, they're not anything) because they have self-contradictions or external contradictions.
If this is claimed of theists then the same must be said of nontheists for reasons stated immediately above. At the end of the day it is a matter of what faith position one will choose.
Incorrect. The ball is in the theist's court. Atheists are still waiting for a pass... until theists justify theism, atheism is 100% justified.
