The key to Williams' mystically oriented theological thought, Descent into Hell (arguably Williams' greatest novel) is a multidimensional story about human beings who shut themselves up in their own narcissistic projections, so that they are no longer able to love, to 'co-inhere.' The result is a veritable hell.

This penetrating study of evil in the human heart revolves around a mysterious Stone of many dimensions, by which one can move at will through space, time, and thought. Replete with rich religious imagery, Many Dimensions explores the relation between predestination and free will as it depicts different human responses to redemptive transcendence.
