Mind, Value, and Cosmos: On the Relational Nature of Ultimacy is an investigation into the nature of ultimacy and explanation, particularly as it relates to the status of, and relationship between, Mind, Value, and the Cosmos. It draws its stimulus from longstanding axianoetic convictions as to the ultimate status of Mind and Value in the western tradition of philosophical theology, and chiefly from the influential modern proposals of A.N. Whitehead, Keith Ward, and John Leslie. What emerges is a relational theory of ultimacy wherein Mind and Value, Possibility and Actuality, God and the World are revealed as ultimate only in virtue of their relationality. The ultimacy of relationality-what Whitehead calls mutual immanence -uniquely illuminates enduring mysteries surrounding: any and all existence, necessary divine existence, the nature of the possible, and the world as actual. As such, it casts fresh light upon the whence and why of God, the World, and their ultimate presuppositions.
