At this point I don't so much object to the OTF, as much as I think it is less than perfectly clear what asks me to do. From the minute I had a conversion experience in 1972 I've been as aggressive as anyone in asking tough questions of my faith. I'm the guy who majored in philosophy because if there were any arguments good arguments against Christianity, I wanted to hear about them while I was still and undergraduate, as opposed to finding out about them when I was older. I would have to say that right up there with the works of C. S. Lewis, I would have to put Russell's The Value of Free Thought as one of the essays that has influenced my intellectual life the most, and I read that in 1972 also. My education, except for three years in a liberal seminary, has been spent in secular institutions which have been relatively hostile to Christianity. I've been as skeptical of Christianity as anyone I know, unless skepticism requires actual disbelief.
But I'm skeptical about a few other things, like the human ability to be completely neutral in evaluating anything. We often go wrong when we assume that just because we stop believing something that some of our peers still believe, that somehow this is due to our intellectual superiority or something like that.
I also am convinced that people should continue believing what they do believe unless there is evidence that suggests they should give up their belief. I have doubts about how far it is possible to make ourselves "outsiders" to our own belief systems, be it Christian, Jewish, atheist, or what not. That is why I am very reluctant to issue diagnoses of intellectual dishonesty or stupidity or what have you. However, our belief systems should be open to evidence, positive and negative, concerning what we believe.
We're all in Neurath's boat, and I think taking all the culturally conditioned planks out is going to cause the boat to sink. I'm pretty convinced by the arguments against classical foundationalism, even when the Cartesian quest for absolute certainty is abandoned. If I were to describe my epistemology, I would describe it as subjectivist Bayesian. We start with whatever we confidences we have, and we adjust those confidences based on the evidence has we encounter it. Bias is gradually eliminated in this way, and over time, if the evidence is strong enough, the prior are swamped and everyone agrees. This may take awhile for religion, not because there are a bunch of brainwashed Christians out there, but because of the sheer complexity of the issue, and the emotional involvement of both sides in it.
A good discussion to get into related to this came up with the idea of "freethinker." Russell defined "freethinker" in terms of the methods people use to decide their beliefs, and Jeff Lowder argued in a paper "Can a Christian Be a Freethinker" that we have no good reason to believe that a Christian couldn't meet those criteria. Unfortunately, in one passage in his essay, Russell presumes that if a university were to hire a Christian in its philosophy department, that person could not be a freethinker.
How could the Outsider Test be presented to someone who believes in subjectivist Bayesianism as an epistemology? Are we being asked to accept a set of evidence against all religious beliefs?
What I fear is that there is an outcome-based criteria for whether someone has really applied the Outsider Test, and that is if they leave the fold. Otherwise, they couldn't possibly have applied the test, now could they?
