In this book, Kuklick traces the continuities between early American theology and scientific philosophy. This book outlines the speculative discourse of New England Congregational Calvinism. The intellectual tradition began with Edwards in the middle of the eighteenth century and concluded with Dewey at the end of the nineteenth. The central protagonists are Trinitarian Congregationalists: Jonathan Edwards, Samuel Hopkins, Nathaniel Emmons, Nathaniel William Taylor, Horace Bushnell, Edwards Amasa Park, the orthodox "progressives" at the Congregational Andover Seminary in the 1880s, and John Dewey. - Publisher.
