91.3 Read more about this topic: U.S. Route 3 Famous quotes containing the word major:“As a novelist, I cannot occupy myself with characters, or at any rate central ones, who lack panache, in one or another sense, who would be incapable of a major action or a major passion, or who have not a touch of the ambiguity, the ultimate unaccountability, the enlarging mistiness of persons in history. History, as more austerely I now know it, is not romantic. But I am.” |
