Amy Post (1802-1889) was not a freethinker (a disbeliever in religion). But she was surely a free thinker. She and her husband Isaac Post (1798-1872) were Hicksite Quakers. The Hicksites were the most radical, progressive Quaker denomination, and in time Amy and Isaac would be judged too radical to remain even among the Hicksites for their vivid activism in abolition, woman suffrage, and other reform causes.
In 1842, the Posts were among the co-founders of the Western New York Anti-Slavery Society, which counted Quakers and non-Quakers among their members. This was considered radical by most Quakers, who tended to keep to themselves, viewing involvements with non-Quakers as "worldly." The Posts opened their home at 36 Sophia Street (now Plymouth Avenue North) in Rochester to radical abolitionist meetings; Frederick Douglass, William Lloyd Garrison, and Sojourner Truth spoke there, as did Susan B. Anthony, who was both an abolitionist and a principal leader of the woman's rights movement. The Posts' home also became an important station on the Underground Railroad.
In 1848 the Posts were driven out of the Genesee Yearly Meeting of Hicksite Friends on grounds that they were too radical and too involved in "worldly" campaigning. They immediately helped to form the Yearly Meeting of Congregational Friends, an ultra-radical Quaker denomination devoted to radical abolitionism, complete sexual and racial equality, and egalitarianism (the group had no elders, vesting equal authority in every member).
Also in 1848, Amy Post and her stepdaughter Mary Post attended the first Woman's Rights Convention in Seneca Falls. They were among one hundred women to sign the convention's most significant product, the Declaration of Senitiments.
The Posts were early converts to Spiritualism. Again in that eventful year of 1848, the Posts welcomed into their home Kate and Margaret Fox, whose pretended communication with spirits by means of rapping noises launched the Spiritualist phenomenon. The Fox sisters made several converts among the Post's radical friends, including Isaac himself, who became a medium and in 1852 wrote a classic Spiritualist book, Voices from the Spirit World.
Yet Amy Post maintained a continuing involvement in the freethought movement. This was not as unusual as it sounds; in the later nineteenth century there was substantial cross-fertilization between freethought, radical Quakerism, and Spiritualism. All three shared a stance of opposition to the powerful Christian consensus of the day; all three contributed more than their share of supporters to the abolition and woman's rights causes.
In 1878, Amy Post attended the Convention of the New York Freethinkers Association in Watkins Glen. There, freethought journalist D. M. Bennett, Boston freethinker W. S. Bell, and sex radical Josephine Tilton were arrested for selling a marriage reform/birth control tract; Amy Post paid Josephine Tilton's bail.
Like Peterboro-based abolitionist/philanthropist Gerrit Smith, Amy Post never embraced irreligion. Yet both Post and Smith embody the commitment to radical reform and eclectic enthusiasm for human-rights causes that define the Freethought Trail.
