James Barr Walker was born on 29 July 1805 in Philadelphia, Pennsylvania, and he died on 6 March 1887 in Wheaton, Illinois. He was a Presbyterian minister, seminary professor, and prolific popular writer on theology and philosophy in the Middle West during the middle decades of the nineteenth century. He was not a philosopher in any academic or professional sense. Like producers of Shakespearean plays before literary specialists took charge of scholarship on the Bard, Walker was a philosophical amateur, writing for a large audience of Calvinist lay people and regaling them with a Platonic interpretation of Protestant Christian orthodoxy. His philosophical credentials were his self-education in classical sources.
