Book excerpt: This anthology collects essays, poetry and treatises by a group of English philosophers from the Age of Reason who were devoted to the goodness of God and the spiritual importance of rationalism. These philosophers, known as the Cambridge Platonists, produced a movement in philosophical theology that flourished around Cambridge University in the seventeenth century and influenced not only Great Britain, but the United States and beyond. Their school of thought emphasized the great goodness of God, the compatibility of reason and faith, an integrated life of virtue, and the deep joy of living in concord with God. This volume introduces and presents the key documents of the Cambridge Platonist movement while setting its thinkers in their historical and religious context: the decades of turbulence and political crises surrounding the English Civil War.
