This type of person titles the middle, dream sequence chapter of Ingeborg Bachmann’s novel Malina. Ernest Shackleton’s claim that an unseen being supported his Antarctic crew inspired a “syndrome” named for one of these people, (-5[2])which T. S. Eliot referenced in a line asking who “up the white road” it is “who walks always beside you.” A poker rule meant to deter players from leaving the table shorthanded is named for one of these people “walking.” One of these people names a (*) regress argument (10[1])attacking the theory of Forms that appears in Plato’s (10[1])dialogue Parmenides. A film titled for this type of person with a zither score by Anton Karas pioneered the use of Dutch angle shots and climaxes in a sewer chase involving Harry Lime, played by Orson Welles. For 10 points, name this title figure of a 1949 film noir directed by Carol Reed and set in Vienna. ■END■ (10[2])
