This course offers an intermediate-level survey of the Rationalist tradition in Early Modern European Philosophy. Broadly speaking, Rationalism (with a capital 'R') is the view that human reason can deliver insight into significant philosophical truths, without relying on sense experience. We will explore varieties of this methodological commitment in connection with several core topics - including the existence of God, the nature of the human mind (or soul), its relation to the body, and the possibility of empirical knowledge. We will read texts by René Descartes, Princess Elisabeth of Bohemia, Margaret Cavendish, Baruch Spinoza, G.W. Leibniz, and Emilie Du Châtelet.
