Marcus is a Columbia institution. He's been teaching at Columbia since the 50s. He's a noted Freudian and has a background in Marxist theory. He runs excellent discussions, and his total disregard for any theory or criticism after, say, 1960 is somewhat refreshing. Marcus can be awfully intimidating, being old, fierce, and sometimes nearly uninteligible. But you get used to it, and, to be honest, his class remains my favorite in the English department. I learned a great deal about writing clearly and beautifully, and about reading poetry effectively and intelligently. My highest reccomendation.
