H. L. Mencken was the most provocative and influential journalist and cultural critic in twentieth-century America. In this volume and a companion, The Library of America presents all six series of  Prejudices  (1919–1927), the iconoclastic collections that helped blast American literature out of its complacency and into a new age of frankness and maturity. The fantastic linguistic inventiveness, full-bodied humor, and unwaveringly fierce courage of his journalism made him a liberating force for his contemporaries. The final three series show Mencken at his lacerating best, taking on targets from religious fundamentalism to the dismal state of higher education. Included are such famous essays as “The Hills of Zion,” his report on the local atmosphere surrounding the Scopes trial in 1925; “In Memoriam: W.J.B.,” his relentless postmortem on William Jennings Bryan; “The Fringes of Lovely Letters,” a hilarious delineation of the lower and outer reaches of the literary world; “Comstockery,” a devastating account of the anti-obscenity crusader Anthony Comstock (“A good woman, to him, was simply one who was efficiently policed”); and “On Living in Baltimore,” a celebration of his beloved native city. Mencken was a man of strong enthusiasms and even stronger antipathies, expressed in a prose style that marshaled all the resources of the American language in a rich blend of comic invention and sarcastic fury. To read  Prejudices  is to embark on an exploration of many curious byways of American culture in a moment of tumultuous and often combative transition. Mencken never shied from combat, and the courage with which he confronted the entrenched truisms and hypocrisies of his time made him a uniquely liberating force in American letter.
