Association with Collegiants and Quakers
By 1656 Spinoza had already made acquaintances among members of the Collegiants, a religious group in Amsterdam that resisted any formal creed or practice. Some scholars believe that Spinoza actually lived with the Collegiants after he left the Jewish community. Others think it more likely that he stayed with Franciscus van den Enden, a political radical and former Jesuit, and taught classes at the school that van den Enden had established in Amsterdam.
A few months after his excommunication, Spinoza was introduced to the leader of a Quaker proselytizing mission to Amsterdam. The Quakers, though not as radical as the Collegiants, also rejected traditional religious practices and ceremonies. There is some reason to believe that Spinoza became involved for a while in a project to translate one or more Quaker pamphlets into Hebrew. In this he would have been aided by Samuel Fisher, a member of the Quaker mission who had studied Hebrew at the University of Oxford. Fisher, it seems, shared Spinoza’s skepticism of the historical accuracy of the Bible. In 1660 he published a book in English of more than 700 pages, Rusticus ad Academicos; or, The Country Correcting the University and Clergy, in which he raised almost every point of biblical criticism that Spinoza was later to make in the Tractatus.
In 1661 Spinoza was visited by a former Collegiant, Pieter Balling, who belonged to a philosophical group in Amsterdam that was very interested in Spinoza’s ideas. Shortly after his visit, Balling published a pamphlet, Het licht op den kandelar (Dutch: “Light on the Candlestick”), that attempted to justify the tenets of Quakerism. The work, which eventually became a standard piece of Quaker theology, contains a fair amount of terminology that Spinoza later employed, which suggests that Spinoza helped to formulate this basic statement of Quaker doctrine.
