Er... well, not yet, but might be a step towards helping.
I get that, if the conditions "different assessor" and "different context of utterance" are separable, then relativism makes distinct claims from contextualism. That is, if I have a different assessor but the same context (or even the same assessor whose epistemic standards have changed, and the same context), then contextualism asserts that the truth value of my claims is necessarily unchanged, and relativism asserts that it might change.
What I can't fathom is how that happens, even in principle. Isn't the assessor, and the assessor's epistemic standards, part of the context of the utterance?
The assessor doesn't have to be a person standing there listening to the utterance. Suppose I told you that my friend Alice says that she knows OJ Simpson killed his wife, and I ask you what you think about her knowledge claim. If you were a relativist, you would evaluate the truth of the knowledge claim in accord with your epistemic standards, or you might even say, "Well, relative to standards X her knowledge claim is true, but relative to standards Y it's false."
If you were a contextualist, on the other hand, you'd ask me "In what context...
Despite being (IMO) a philosophy blog, many Less Wrongers tend to disparage mainstream philosophy and emphasize the divergence between our beliefs and theirs. But, how different are we really? My intention with this post is to quantify this difference.
The questions I will post as comments to this article are from the 2009 PhilPapers Survey. If you answer "other" on any of the questions, then please reply to that comment in order to elaborate your answer. Later, I'll post another article comparing the answers I obtain from Less Wrongers with those given by the professional philosophers. This should give us some indication about the differences in belief between Less Wrong and mainstream philosophy.
