Abstract
In the present article, I aim at showing a shift in Berkeley’s understanding of society in the late Siris. Although the work is primarily devoted to the curative qualities of tar-water and on the speculative level develops a new neoplatonic metaphysic of light, it should also be seen as a work in which Berkeley’s mature philosophy is expressed as a whole. Together with the fact that since the thirties Berkeley thought was more inclined towards practical, i.e. economic and social, issues, this might be a premise for interpreting the Siris as a work in which a vision of society is presented. The parallelism of nature and society, of macrocosm and microcosm, and the claim that nature is not perfect, but is a dynamic, developing whole, makes it possible to treat society as an imperfect whole developed and perfected by human activity. If such a reading is correct it evidences the fact that in his Siris Berkeley abandoned the religious radicalism typical for his early works.
