This collection of previously unpublished essays on Spinoza provides a representative sample of new and interesting research on the philosopher. Spinoza's philosophy still has an underserved reputation for being obscure and incomprehensible. In these chapters, Spinoza is seen mostly as a metaphysician who tried to pave the way for the new science. The essays investigate several themes, notably Spinoza's monism, the nature of the individual, the relation between mind and body, and his place in 17th century philosophy including his relation to Descartes and Leibniz. The top scholars working on Spinoza today are all represented, including John Carriero, Michael Della Rocca, and Don Garrett.
