This book contains the lectures which Dr. H. Evan Runner presented to two student conferences in 1959 and 1960. Runner was professor of philosophy at Calvin College in Grand Rapids, Michigan, from 1951 until 1981, when he became professor of philosophy emeritus. The conferences were sponsored by the Association for Reformed Scientific Studies, now called the Association for the Advancement of Christian Scholarship, which today owns and operates the Institute for Christian Studies in Toronto. They were presented at a conference center in Unionville, a lovely little village just to the north of Toronto. The audience consisted primarily of students, teachers and preachers of Reformed background who had emigrated from Holland to Canada after the second world war.
