A solution emerges at long last. This metaphor, evoking the end of a long, dark mining or railroad tunnel, came into widespread use only in the mid-twentieth century. It was used by President John F. Kennedy in a 1962 press conference on the Vietnam War and became common throughout that conflict. However, the image was used nearly a century earlier in a letter by English novelist George Eliot, and the expression also appeared in a letter from J. Middleton Murry to his wife, Katherine Mansfield (1922): “I begin to feel that the horror may move away and that there is a big round spot of real daylight at the end of the tunnel.”
