Rational Justification
How are our beliefs justified? What counts as a rationally justified belief and what counts as an irrational claim?
In order for a belief or claim to be rationally justified, it must have justifying reason behind it. However, as many have pointed out, this seems to lead to problems with basic beliefs that we all take for granted, such as universal, invariant noncontradiction. What reason could anyone have for believing in noncontradiction? It doesn't seem possible for it to be a conclusion, because it must be presupposed in order to come to any conclusion. But how can justifying reason be behind a claim of noncontradiction if it has to be presupposed to come to any conclusions? Noncontradiction seems like an arbitrary assumption!
Many people have philosophically (though almost never practically) embraced solipsism as a result of the difficulty of first principles (or first premises, or ultimate presuppositions).
It seems to me that there are three and only three methods by which beliefs can be rationally justified.
Initially, either the justifying reason behind my belief is my own reason, or it is someone else's reason. There are no other options.
Someone Else's Reason
1. Imputation
If it is someone else's reason, then the belief or claim has been imputed into me, and its justification (or lack thereof) goes along with it.
Imputation, the first of the three methods, is seen when we recognize that the premises of a calculator are rationally justified. The calculator's reason didn't justify its premises: they were justified in the mind of its creator.
My Reason
On the other hand, if it is my reason, it is either my reason by means of my will, or it is my reason regardless of my will. Again, there are no other options.
2. Authorship
If it's my reason by means of my will, then I'm the author of the fact and also the author of the claim. All of C.S. Lewis' claims about Tumnus the Faun are rationally justified, because Lewis' will simply is the authority regarding the facts about Tumnus. Authorship is the second method.
3. Discovery
Finally, if it is my reason regardless of my will, then I have engaged in discovery. Discovery is the third and final method. Discovery always involves conclusions based on prior premises. If the premises are not justified, the conclusion likewise is not justified.
Minting the Coin or Passing the Buck
It seems to me that these are literally the only three possible methods for rational justification of a claim.
However, two of these methods (imputation and discovery) simply kick the can down the road. Imputation takes an already-justified claim and moves it from one claimant to another; while discovery takes already-justified claims and uses them to formulate a new claim.
Authorship is the only method of the 3 that actually provides ultimate rational justification for a claim: the justifying reason behind it.
Therefore, it seems to me that our first principles -- if rationally justified -- are imputed to us by their author. And, the author of our first principles is the willful author of universal invariant truths, and therefore the author of time and space.
In other words, if you are rational, then God exists.

"Who was Cain's wife?"
According to the Bible, Adam and Eve, the two first people (Genesis 2), initially had two sons, Cain and Abel (Genesis 4:1-2). Cain murdered his brother Abel (Genesis 4:8), took off into the Land of Nod (Genesis 4:16), and had many descendants (Genesis 4:17-24). We aren't told specifically who his wife was.

"Isaiah 7:20 says the Lord is going to be a barber and shave the hair off our legs. Is there any reason for this random stuff?"
Isaiah 7:20 (NASB) In that day the Lord will shave with a razor, hired from regions beyond the Euphrates (that is, with the king of Assyria), the head and the hair of the legs; and it will also remove the beard. This does seem like an odd verse when pulled out of its full context, but reading the entire passage in historical context and in light of the law of Moses, specifically Leviticus 14, the meaning becomes apparent.

"Mr. McCabe, you obviously don't read your own Bible. On the first page alone (Genesis) in the Arabic Bibles around the world the word Allah is there 17 times. YHWH was only given in Exodus, there aren't any vowels, so why did you say Yahweh?"
This question appears to be in response to my answer to the question "Aren't Allah, Brahman and Yahweh just different names for the same God?". Thanks for your comments. When I read the question "Aren't Allah, Brahman and Yahweh just different names for the same God?", my understanding was that the questioner was suggesting that it was possible that we all worship the same God, just by different names. The thrust of my argument was that we worship different Gods.
