The Rationalists: Descartes: Discourse on Method & Meditations; Spinoza: Ethics; Leibniz: Monadology & Discourse on Metaphysics
Founded in the mid-17th century, Rationalism was  philosophy's  first step into the modern era. This  volume contains the essential  statements of  Rationalism's three greatest figures: Descartes, who   began it; Spinoza, who epitomized it; and Leibniz,  who gave it its  last serious expression.
