Another of Bradbury’s nationalistically oriented stories, “The Great Collision of Monday Last” treats several of humanity’s blacker desires. Here, he depicts the thrill which a person feels when he flirts with danger and the unknown, and when, more specifically, he readies himself for the possibility of destroying a life. McGuire may be an American, but the thrill associated with danger and destruction serves to break down all nationalistic barriers because it is common to all people. In this respect, McGuire and the men at Heber Finn’s pub are brothers.
