The post Cartesian era of philosophy witnessed Benedict de Spinoza rise to prominence in the late 17th century. revered as one of the great rationalist, Spinoza built upon, and often disagreed with, the philosophical foundation provided by Rene Descartes. Spinoza is best known for Ethics, his metaphysical approach to rational philosophy. within the ethics, Spinoza takes a notably divergent approach from Cartesianism in which he presents the doctrine of the single substance to explain how the universe works.

HIs contribution to philosophy not only questioned Cartesianism, but also basic theology as a whole. HIs single substance theory marked the stark divergence from Cartesianism and a new branch of monistic philosophical thought.
