Slouching Towards Gomorrah: Slouching Towards Gomorrah: Modern Liberalism and American Decline is a 1996 non-fiction book by former United States Court of Appeals judge Robert H. Bork.  Bork's thesis in the book is that American and more generally Western culture is in a state of decline and that the cause of this decline is modern liberalism and the rise of the New Left.  Specifically, he attacks modern liberalism for what he describes as its dual emphases on radical egalitarianism and radical individualism.  The title of the book is a play on the last couplet of W. B. Yeats's poem "The Second Coming": "And what rough beast, its hour come round at last, / Slouches towards Bethlehem to be born?"  Bork contends that the "rough beast of decadence … now sends us slouching towards our new home, not Bethlehem but Gomorrah."
