David W. Aiken investigates the possibility of denying that God is essentially and necessarily good. After disentangling this issue from problems of theodicy and theistic proof, he goes on to explore various constructions of the proposition, "God is not necessarily good." In the process of refuting each of these alternatives, he shows how far God's goodness must be regarded as an indispensable foundation of theistic belief and practice, then proceeds to clarify in what sense "goodness" may be predicated of God. The essay concludes with a consideration of the implications of this issue for spiritual direction. Mr. Aiken is Assistant Professor of Philosophy at Gordon College.
