Chapter 2 follows the rise of Anthony Comstock from being a dry goods clerk and vigilante against all things he deemed immoral, to becoming the nation’s most prominent and powerful censor. He was responsible for enacting federal legislation banning obscene materials from the US Mail and served as a special agent for the Post Office, enforcing the law. He founded the New York Society for the Suppression of Vice, an anti-vice organization that was emulated in numerous other states. From this position, he waged a lifelong crusade against contraceptives, free love, free thought, literature, art, and everything that offended his Puritan sensibilities. The chapter describes the key events in his long career, including his rise to prominence, his prosecution of Victoria Woodhull for revealing Reverend Henry Ward Beecher’s affair with a parishioner, his various campaigns against free thought, art, and literature, and his prosecution of birth control advocates.

Chapter 4 sets forth the “Comstock Playbook,” the techniques used by the anti-vice crusader to attack his adversaries, which have been emulated by censors ever since. His strategies include exhibiting moral certainty, equating opposition to your cause with the love of vice, denouncing and discrediting adversaries, promoting xenophobia, poisoning the debate with invective, touting pseudo science, seeking publicity, exaggeratingthe threat to be overcome, hyping all accomplishments, and playing the martyr.

Religion was a force throughout Twain’s lifetime, early on as the strict Calvinism inherited from his mother, and later as he rebelled against orthodoxy. His reading of Thomas Paine at an early age introduced him to religious skepticism, which challenged the beliefs he held as a child. Despite his skepticism, he was very close with a number of clergymen, most notably his family minister Joseph Twichell, who may be considered his closest adult friend. He vowed to reform and become a devout Christian in order to marry Olivia Langdon, but his “reform” ended after a year or so. In many of his works, he satirically exposes religious hypocrisy, and in his later unpublished writing, most notably Letters from the Earth (not published until 1962), he expresses doubt and scorn for conventional Christianity.
