Perfect Being Theology

Introduction

In this topic, we will look at the method for philosophizing about the nature of God usually called “perfect being theology”. Perfect being theology is a way of reasoning about God’s nature by reflecting on what follows about God if we define Him as the best being which could possibly exist, and we reflect on our knowledge of right from wrong, better from worse. The method of perfect being theology is usually seen as described explicitly for the first time by St Anselm of Canterbury in the Middle Ages: the philosopher responsible for the first version of the ‘ontological argument’ for God’s existence, which is itself a piece of perfect being theology. But arguments that God must be some way, rather than another, because He is perfect are at least as old as Western philosophy. The sacred texts of the Western monotheistic, or ‘Abrahamic’ religions, Judaism, Christianity, and Islam, all describe God in a way which led theologians in these traditions to use perfect being theology when thinking about God. Perfect being theology holds out the promise of a systematic method for investigating God’s nature and existence which does not rely on ‘faith’ or ‘revelation’.

Introduction

Doubts about the meaningfulness of claims about God’s nature, and the objectivity of right and wrong, made popular in the first half of the twentieth century were largely overcome in the latter half. One result is that in contemporary philosophy of religion there has been a huge revival of perfect being theology. But even if we have knowledge about morality, can and should we attempt to use this knowledge to investigate the nature of God? Or are there good reasons for theologians to be skeptical or wary of perfect being theology? How successful has perfect being theology been in the past, and what are its prospects?

Instructions

Work through each activity in turn, answering the questions at the end of each PDF. The ‘Useful Links’ section links to two online editions of Anselm’s Proslogion, which you can use to help you with the tasks.

Contemporary (and some slightly older) philosophical articles and books are referenced in the text using footnotes. You do not need to have access to them for the purposes of these exercises, but a lot of progress in philosophy takes the form of contemporary writers articulating more explicitly and precisely what is implied in the work of their predecessors, so it’s good to be aware of and give credit to contemporary thinkers. Ancient and medieval sources are cited in the footnotes. Often they appear with the name of the source or an abbreviated version and then followed by some numbers, usually chapters or rather than page numbers. This means that you can find that reference regardless of which edition you are using.

The Proslogion can be found in PDF here and in HTML here.

    This University of Notre Dame paper shows some of the methodology for thinking about this question. The maths is a bit tricky, but if you can get past that and look at what the author is trying to do it can still be useful.
