«This welcome volume brings together writings by Professor Grisez and Fr. Ryan on the ultimate question: Into what kind of relationship with Him does God finally call us? To illuminate this most profound of questions, the full resources of reason must critically be brought to bear on the data of faith. Students of philosophy and theology, and especially those who are interested in the relationship between these scholarly disciplines, will be instructed both by the content of what Grisez and Ryan say and the example they set of rigorous and creative thinking.» (Robert P. George, McCormick Professor of Jurisprudence, Princeton University)
