Two answers required. A Ruth Millikan paper on these two philosophers proposes an innate “biological purpose” that is seen in the mating behavior of hoverflies. A paper mostly about these two philosophers by Paul Boghossian distinguishes “Sellarsian” and “Gricean” views of the interplay between meaning and thought. One of these philosophers used the possibility of mistakes to critique responses to the other that emphasize a person’s “disposition.” (15[1])In discussing one of these philosophers, the other imagined an (*) operation (10[1])that ceases (-5[1])to be addition (10[1])when (10[3])either (10[4])summand (10[3])hits 57, (10[3])called the “quus” (10[1])function. (10[2])The (10[1])names of these two philosophers are often merged into a monster-like portmanteau because of a book by one of them titled for the other “on Rules and Private Language.” For 10 points, name these philosophers of language who wrote, respectively, Philosophical Investigations and Naming and Necessity. ■END■ (10[1]0[3])
