 By way of contrast, Hartshorne’s logic of perfection is dipolar. Within each element of these pairs there are good features that should be attributed in the preeminent sense to God (e.g., excellent permanence in the sense of steadfastness, excellent change in the sense of preeminent ability to respond to the sufferings of creatures). In each element in these pairs there are also invidious features (e.g., pigheaded stubbornness, fickleness). The task for the philosophical theist, he thinks, is to attribute the excellences of both elements of these pairs to God and to eschew the invidious aspects of both elements. However, it should be noted that some contrasts are not fit for dipolar analysis (e.g., good-evil) in that “good good” is a redundancy and “evil good” is a contradiction. The greatest conceivable being, he thinks, cannot be evil in any sense whatsoever.
