I bumped into <a href="http:&#x2F;&#x2F;philpapers.org&#x2F;archive&#x2F;FRAQTV.pdf" rel="nofollow">http:&#x2F;&#x2F;philpapers.org&#x2F;archive&#x2F;FRAQTV.pdf</a>, which argues that most answers will trivially fail.<p>I felt the answer should involve degrees of truth, which can roughly be calculated as &quot;percent of people who agree with the classification&quot; for some reference class, and this degree of truth gradually decreases. But you can&#x27;t assign any arbitrary cutoff number where above it is true and below false.<p>The way to combine two statements would be to likewise ask what portion of people agree with both, which seems to avoid some of the critiques of degrees of truth.<p>This is only for problems of classification over human undefined terms, where the argument from common usage is valid.<p>Does this have any major problems?
