The phrase "This is the way the world ends" is from the poem "The Hollow Men" written by the modernist poet T. S. Eliot. The full famous line is: "This is the way the world ends / Not with a bang but a whimper." It appears in the final stanza of Eliot's 1925 poem, which explores themes of disillusionment and an anticlimactic end rather than a dramatic one. T. S. Eliot was a significant poet of the 20th century known for his influential modernist works.
