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."

Reflections on Having Left a Place of Retirement: Reflections on Having Left a Place of Retirement is a poem written by English poet Samuel Taylor Coleridge in 1796.  Like his earlier poem "The Eolian Harp", the poem discusses Coleridge's understanding of nature and his married life, which was suffering from problems that developed after the previous poem.  Overall, the poem focuses on humanity's relationship with nature in its various aspects ranging from experiencing an Edenic state to having to abandon a unity with nature in order to fulfill a moral obligation to humanity.  The discussion of man's obligation to each other leads into a discussion on the difference between the life of a philosopher and the life of a poet.  By the end of the poem, the narrator follows the philosophical path in a manner similar to what Coleridge sought to do.  The response to the poem from critics was mostly positive with many of them emphasizing the religious aspects of the poem in their analysis.
