Aquinas doctrine of analogy was intended to reconcile a philosophically credible concept of God, a God who is wholly “other”, with the human ability to speak about Him in meaningful terms. Aquinas, who based his worldview on that of Aristotle, saw that God’s existence is best demonstrated a posteriori, from experience. Four of his famous five ways show that God is what Aristotle called the “Prime Mover”, the originating and sustaining cause of everything which also defines the final cause of the universe and explains its teleological character. This suggests that for Aquinas’ God, like Aristotle’s prime mover, is eternal outside time and space, impersonal and transcendent. As Maimonides pointed out, this means that claims about God should not be understood univocally, because the edge of time and space – and thus possible experience – is like a “veil and partition” between God and us. What it means for God to be good cannot be the same as what it means for a human being to be good… There is no time or choice for God, after all. Nevertheless, Aquinas disagreed with Maimonides about the apophatic way being the only way to speak concerning God. Aquinas saw that religion cannot be well supported by negative language, also pointing out that one has to have a clear concept of what God is to be able to decide what God is not. Therefore, Aquinas’ doctrine of analogy attempted to define what can be said about God in positive terms, steering people away from univocicity whilst preventing claims from being seen as equivocal either. Nevertheless, Aquinas’ doctrine of analogy does not enable us to speak significantly enough about God.
Firstly, Aquinas’ doctrine of analogy is too limited to support the meaningfulness of morality. For Aquinas, I can say that God is good meaningfully. Through analogy of proportion, by saying that God is good I know that God is 100% actual and has no potential, because the meaning of goodness is that something fulfils its nature and God, being atemporal, can do nothing other than 100% fulfil his nature. Further, through analogy of attribution, I know that God’s goodness is unlike human goodness and yet it has a causative relationship with human goodness in the way that the goodness of the baker or the bull has a causative relationship with the goodness of the bread or the urine. Relatedly though more broadly, through Aquinas’ analogy of being, I know that the being of created contingent things is secondary to the primary being of God. In the way that the healthiness of a yoghurt is secondary and the healthiness of the person who eats the yogurt is primary, so the being of God is primary and supports the being of all other things, although what it means for God to be and created things to be is not the same. Nevertheless, knowing that God is 100% whatever God is and that his goodness and being enables things in the world to be good and be does not really tell me anything significant about God’s nature, other than perhaps that he intends things to fulfil their various natures as He fulfils His timelessly. Aquinas built his theory of natural law on this analogical understanding of God’s nature and tried to extrapolate moral norms from it, suggesting that it is God’s will that human beings fulfil their common nature and that actions which contribute to this end are good. Yet Natural Law struggles because there is no clear and consistent account of what the common human nature, that God wants us to fulfil in order to be good, is. For one example, while Aquinas saw procreation as a necessary part of this human nature and thus essential to human goodness, Chappell and originally Finnis disagreed, not seeing procreation as a necessary part of human nature or essential to goodness at all. Their position is strengthened by Aquinas own argument that some goods pertain to certain men more than others, hence a priest may be celibate because he is pursuing the good of praising God which conflicts with the good of having children in practice. The fact that people can’t agree on what a common human nature entails, despite being able to experience and observe this, emphasizes how little content there can be within the claim “god is good” – or any other claim about God’s nature – when understood analogically. Further, having so little idea of what God’s goodness entails forces us to rely heavily on a contested definition of human nature, meaning that an analogical approach to religious language fails to support morality. This shows that Aquinas doctrine of analogy does not enable us to speak significantly enough about God, because it only serves to emphasis how little we can know about God’s goodness and fails to support morality.
Secondly, Aquinas’ doctrine of analogy does not support the meaningfulness of the Bible or central documents such as the Nicene Creed. From the Bible we know that God spoke on numerous occasions, appeared in visions and had relationships with Prophets and with Jesus, and yet again, Aquinas’ doctrine of analogy emphasizes the “otherness” of God, which undermines these essentially Christian beliefs. At least Maimonides admitted that Scripture should be read as myths and legends, yet Aquinas never went this far. According to Aquinas’ doctrine of analogy, we can only speak analogically of God because God is outside time and space and what Tillich later called “the ground of our being”, yet this is not the impression that (most of) the Bible gives. As Nelson Pike pointed out, the Bible’s God acts in a way that is “unavoidably tensed” and apparently at odds with an analogical interpretation of religious language. For example, Aquinas would suggest that a claim that “God created the heavens and the earth” should not be understood univocally. God’s creative act cannot be like a creative act of say a potter. Rather, God’s creative act must be simple and single, as befits his timeless-eternal nature. This means that all parts of God’s creative action are concurrent, just as all God’s various attributes are different ways of understanding God’s wholly simple nature. There can be no division between parts of God’s act in creation, just as there can be no division between God’s goodness and power, his power and knowledge for examples. How then can we make sense of the Biblical salvation narrative? Analogically, Aquinas would have us believe that God’s act in creation is not like a human act, having no time before, during or after and no alternative possibilities. How though can the creation be concurrent with the fall and with the incarnation and final judgement? This makes no sense of central Christian doctrines. Also, the doctrine of the Trinity is problematic, because it suggests that God is best understood through the three distinct persons of God. Aquinas’ doctrine of analogy suggests otherwise… indeed we must focus on the very oneness of God to make sense of what we can say and mean analogically through proportion, attribution and being more generally. This inability to support claims made in the Bible and creeds also shows that Aquinas’ doctrine of analogy is too limited to enable Christians to speak significantly of God.
Of course, Aquinas’ theory of analogy has its supporters and indeed enables us to speak more significantly about God than does the via negativa. Aquinas’ theory of analogy is highly influential within modern Roman Catholicism and has been developed by thinkers ranging from Ian Ramsey to Austin Farrar and Gerard Hughes. Even John Hick praised Aquinas analogical approach to religious language. Ramsey noted how people naturally see claims made about God as “logically odd.” When we use words like power or love in relation to God, we know that we don’t intend people to interpret them in the same way as they would in ordinary language. Words are in a sense “models” of what we mean about God; just as a model of an atom in a science lab isn’t adequate to express the structure of the atom or the concept of the light-wave to express how light works, so the word “power” isn’t entirely adequate to express that attribute of God, but it is the best means of expression that we have. Further, Ramsey noted that we use “qualifiers” such as “Holy” to indicate that we are using a “model”, that our claim is “logically odd” and that our intended meaning relative to God is not the same as the common meaning of words such as power or knowledge. Hick praised this aspect of analogy noting that it allows us to speak significantly about God while also preserving the essential mystery and ineffability of the divine. Hughes suggested that the qualifier “timeless” is most appropriate to signify that words are being used analogically, drawing the mind to that part of a common meaning that makes sense in relation to the timeless nature of God. Thus for the Thomist, when I say “God is good” I should say “God is timelessly good”, ruling out a moral interpretation of the claim which would be incompatible with God’s eternal nature. This shows that an analogical approach to language fits in with modern Roman Catholic beliefs and usage, supporting the significance of some important things that Catholics say about God. Yet Aquinas’ analogical approach to religious language still fails to enable us to speak significantly about God for two reasons.
- Firstly because some Roman Catholic writers were critical of Aquinas’ analogical theory of religious language straight away. For example, John Duns Scotus preferred the Cataphatic approach of St Anselm and St Bonaventure. An analogical approach to language is, for Scotus, too limited to support significant religious beliefs and utterances. Instead, Scotus argued that we should be able to speak univocally of God since the very concepts we use to describe and affirm his characteristics were created by God as part of his simple, single act of creation. His approach owes more to Plato than it does to Aristotle, suggesting that God is more like the Form of the Good, giving definition to the concepts through which we experience reality and so knowable through reason and describable in ordinary language.
- Secondly, because while analogy does seem intuitive to those whose worldview includes a timeless-eternal God, it is less so for those whose worldview includes a personal, immanent God. How is the claim that God is timelessly wise, as Hughes might have it, compatible with the claim that God knows “the inmost secrets of our hearts” as the Psalmist affirms, let alone with the claim that God hears and answers prayers? God’s wisdom should not be understood univocally, and should only be taken to mean that God has 100% of the knowledge appropriate to God, being timeless, and that God’s knowledge and our knowledge have a causative relationship of some sort, God’s wisdom being primary and ours secondary in the way that the health of a person is primary and of a yoghurt is secondary. Neither of those understandings support the significance of my belief that God knows what is in my heart right now, or is capable of understanding and answering me personally.
Of course, Aquinas’ doctrine of analogy is still better than Maimonides via negativa. The via negativa wouldn’t let me say anything positive about God’s wisdom or knowledge at all, supporting only the claim that “God is not ignorant” for example. Yet in practice the content supported by the doctrine of analogy is only a little more significant than that supported by the via negativa, and as has already been argued, is certainly not sufficient to do justice to the range of Christian beliefs or documents such as the Bible or the Creed. This shows that Aquinas’ doctrine of analogy does not enable us to speak significantly enough about God.
In conclusion, while Aquinas doctrine of analogy supports us in speaking more significantly than does the via negativa, it still does not enable us to speak significantly enough about God to support Christian faith. Being Christian demands that God is and can be said to be personal, immanent, active through the Bible and in the world today, not to mention incarnate in Jesus who was fully God as well as fully man. Aquinas’ doctrine of analogy is far too limited to enable Christians to articulate these significant beliefs. Better understandings of religious language from this point of view include symbol and metaphor, both of which allow a greater variety of things to be said meaningfully than does analogy.
