The January 2, 1895, edition of the Arizona Weekly Journal-Miner featured this notice: “If you fail to attend Putnam’s lectures, you will always regret it. Such treats of reasoning of eloquence of Encyclopedic knowledge, don’t come our way every day.”
The lecturer was Samuel Porter Putnam, a leading advocate for the Freethought movement. A former Unitarian minister, Putnam founded the Freethought Federation of America (which later merged with the American Secular Union) in 1892. Freethought philosophy held that people should rely on their own human reasoning rather than on religious doctrines and beliefs. Putnam frequently traveled the country, delivering lectures and promoting the creation of local Freethought Federation chapters.
