Answer exаctly five оf the fоllоwing six questions. Eаch is worth 20 points. (1) Gottlob Frege distinguishes Sense аnd reference. Each plays an important role in his theory of language. Explain Frege’s distinction and how he applies it to singular terms and sentences (2) “The present king of France is bald”. Explain how Bertrand Russell analyzed this sentence and then explain either P.F. Strawson’s or Keith Donnellan’s criticism of Russell. (3) Saul Kripke argued that proper names are rigid designators. Explain what this means and how his view differs from the description theory of names. (4) Hilary Putnam argued for semantic externalism about natural kind terms (like “water” or “elm tree”). Explain what semantic externalism is and how he argued for it. (5) “Romeo loved Juliet” is a statement involving fictional names. Gotttlob Frege’s theory would seem to say that this sentence is neither true nor false, and Bertrand Russell’s theory would seem to say that it is false. Yet there are views of fictional names according to which this sentence is true. Explain two of these views. (6) Ludwig Wittgenstein’s views about language dramatically changed over the course of his lifetime. Explain the key differences between Wittgenstein's early and later views of language. ***Each answer should be roughly two paragraphs long. Be sure to fully explain yourself.
