Sophia Dobson Collet was a 19th-century English feministfreethinker. She wrote under the pen namePanthea in George Holyoake's Reasoner, wrote for The Spectator and was a friend of the leading feminist Frances Power Cobbe.
Collet was a supporter of the South Place Ethical Chapel and wrote several hymns for the organisation. Her brother Charles was its musical director. She was friends with the South Place composer Eliza Flower and Sarah Fuller Flower Adams. It is at South Place that she came into contact with George Holyoake. She would contribute to both The Reasoner and The Movement from the 1840s to 1850s as well as have continued correspondence with Holyoake long after. She is also credited with preserving many of Fox's writings. She wrote an appraisal of George Holyoake and his work inGeorge Jacob Holyoake and modern atheism: a biographical and critical essay in 1855 which was well received. The book was an expanded version of what she had written as Panthea in the Free Inquirer. It echoed the same conciliatory tone between religion and non-religion that Holyoake had long espoused.
Feminism
Collet remained a Unitarian even as South Place moved into a non-religious direction. However, she "condemned the oppression of women in Scripture and the subordinate position assigned to them by Christianity." She joined the Moral Reform Union, wrote articles on women's education and supported William Thomas Stead during his imprisonment in 1885. Stead would occasionally attend lectures at South Place. Her efforts to help Josephine Butler repeal the Contagious Diseases Acts in India put a strain on her relationship with Richard Holt Hutton of The Spectator. Her name appears on the petition for female suffrage published by The Fortnightly Review.
Later life
Collet met Ralph Waldo Emerson and had a lifelong interest in transcendentalism. Moncure D. Conway recollected in his autobiography that Ralph Waldo Emerson had asked after her as well. She also had an interest in Brahmo Samaj and the Hindu reform movements. She published several books on this topic including The Brahmo Year-Book, Lectures and Tracts by Keshub Chunder Sen, A Historical Sketch of the Brahmo Somaj, Outlines and Episodes of Brahmic Histor. F. H Stead published the Life and Letters of Raja Rammohun Roy after her death in 1900. She is buried in Highgate West Cemetery.
