He didn’t say he relies on bias, but upon faith.
exactly. he was relying on the biases of the christian faith.

how does that make him any different from those who ‘search for the truth’ while relying on the biases of the Muslim Faith, the biases of the Hindu Faith, etc.

Exactly what? :confused: One can have faith in something and have evidence for it at the same time. One can believe something without having any evidence for it and still be right - it can still be the truth. If you are going to equate faith of any kind with bias, then you are just as biased as everybody else. Let me explain.

You believe there is a God, which means that you believe that God is something - has certain attributes. Otherwise the word “God” would be meaningless. Do you have a deductive proof for the existence of this God? No, at least not that you’ve explicated so far. Do you have some evidence that God exists with the attributes you claim. Yes. Do you believe you have better evidence for it than the God of Christianity or Islam or Hinduism (although I think that’s a misnomer for Hinduism)? Yes. Are you biased? Hmmm… Guess what, Christians also believe that they have better evidence than the Muslim than the Hindu, and yes, than you about who God is. It does not mean that faith in certain things about knowledge and about God makes one biased.

But back to the OP. How can we know that reason is true? We have to use reason at the outset to justify reason. I have never seen a proof that the laws of logic are self-justifying, much less that they are universal both temporally and spatially. You have to assume these things, and on faith. A skeptic might even go further than that though. He might claim that there is no justification for those beliefs at all, meaning that you are indeed showing your bias. How would you answer him?

The “but I’m neutral and you aren’t” argument is bogus. To know anything at all you have to accept certain things on faith.

that can happen. but its more about luck than proper reasoning.

i’m not equating faith “of any kind”. This is a case to case basis. Bias only comes around if you are looking for truths concerning faith, and yet you are already influenced by the kind of faith that you are searching for. Like a muslim raised individual looking for religious truth. What are the chances that he will find the ‘truth’ in Islam?

my belief in god is 50% reasoning and 50% faith. that means reasoning alone is insufficient, incomplete. and no way to tell if its true or not.

really? like the laws of substitution isnt self-justifying for you? a+1=2, if a=b then b+1=2.
 
that can happen. but its more about luck than proper reasoning.
I agree. I think that somebody who doesn’t have any evidence for a belief, even if it turns out to be correct, is a likely candidate for bias. But that is not the same thing as believing certain things on faith.

I don’t know what the chances are, and I don’t really care. Neither should you. It would be a waste of time to investigate the social and psychological background of every person you argue with to discover if any of it influences their beliefs concerning reasoning and faith. The arguments will stand and fall based upon their own merits, not based upon what influences might have motivated them to make the argument.

There is no reason for you to believe that your evidence for God’s existence is insufficient to qualify as truth or as knowledge. I read your arguments in this post: forums.catholic-questions.org/showpost.php?p=2858682&postcount=44
You give your arguments far too little credit.

Now you may say that this is a mere belief of yours. It isn’t knowledge. It isn’t truth. So you would be fine with it if Christians would just say that they have a belief in their God, and it isn’t any better than anybody else’s belief in their God, including your own. Of course that presupposes that there are standards by which these beliefs can be judged as true or false, as mere belief rather than knowledge. The question is: what are those standards based upon? What happens if they are based at least in part upon faith?
really? like the laws of substitution isnt self-justifying for you? a+1=2, if a=b then b+1=2.
Yes, really. Mathematical laws like that of substitution are based on logical principles and, believe it or not, on observation. Quantities like “one” and “two” are derived from the empirical and are then put into representative symbols. Mathematics are justified based upon other things. The logical principle of identity. The existence of such things as quantity and extension in the world. They are pretty clearly not self-justifying, and neither are the principles that justify mathematics.

On the contrary people like me, apologists and missionaries, should care. Like when confronted by muslim raised people who claim to have searched for the truth and found it in islam, should be ready to explain the bias of their ‘search’.
It would be a waste of time to investigate the social and psychological background of every person you argue with to discover if any of it influences their beliefs concerning reasoning and faith.
you dont have to. just realize the fact of human mind behavioral patters which seeks to justify what its already comfortable with.
The question is: what are those standards based upon? What happens if they are based at least in part upon faith?
i believe in compelete freedom of belief. with that said i would say that such standards should only apply within the confines of discussions and debate. And as always the standard would be: extraordinary claims require extraordinary evidences.
 
Philosphocally speaking, your answer might be: Take a Philosophy course in Logic. Do the readings. Master the materials. Ace the course. Now you’re set to review your own reasoning, kind of forever. (key word: syllogisms)

Who is this addressed to?

The problem with this idea is that it assumes that the logic taught in the course is true.

Logic is taught as a system of syllogisms and then as an application of those syllogisms. It’s sort of a “can’t fail” way to examine “reasoning.” In fact in RC Schools of Theology and RC Seminaries, the preference (often the obligation) is for students to master Logic and then they take a course in Ethics. It’s systemic learning at its very best.
