The three theories of truth are different attempts to taboo the word "truth".
Isn't this the point? Tabooing "truth", one can see that the theories really speak about (slightly) different concepts. Going back to your previous example, if one theory claims the scientists have reached the truth and the second doesn't, how does it change the reality? You can easily define some new words to correspond to the different concepts, and refer to the appropriate label under the different circumstances.

Then, you would merely choose which of the concepts is the one needed for a particular theoretical purpose. Right?
Wrong! The arguments go to the concepts' coherence. This is why it's philosophy, not lexicography.
For example, a correspondence theorist generally argues that the notion of an epistemological limit to which scientific findings converge need not exist and can never be established empirically. If correspondence theory is true, you aren't...
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.
