Rethinking OUR Natural KNOWLEDGE OF GOD

Reformed theologians since John Calvin have emphasised the immediacy of at least some of our natural knowledge of God, as well as the necessity of spiritual regeneration and the epistemic efficacy of the Holy Spirit for much of the rest of our knowledge of God.[1] In Warranted Christian Belief (hereafter WCB), Alvin Plantinga provides a rigorous philosophical development and defence of these long-standing Reformed ideas over against various epistemic objections to theistic and Christian belief. In particular one must be impressed with Plantinga’s careful analysis of important epistemological details, something typically absent from earlier Reformed thinkers.

 

These merits notwithstanding, advocates of natural theology and more traditionally minded religious philosophers may be disappointed with WCB on two counts. First, unlike other works in philosophy of religion and religious epistemology, no attempt is made to provide arguments for God’s existence, though considerable and laudable effort is put toward answering various objections to Christian belief. Of course, Plantinga has elsewhere argued for the importance of theistic arguments. In fact, he has outlined and developed a variety of such arguments himself, some of which he thinks are good arguments.[2] In WCB Plantinga is presenting a model of how theistic and Christian belief can be warranted, and his main argument is that there are no plausible objections to this model that do not presuppose the falsity of theism. So we must conclude, I think, that the presentation of theistic arguments simply falls outside the scope of the project Plantinga is carrying out in WCB. Secondly, though, there might be a related concern. The model Plantinga presents involves theistic and Christian belief having warrant in a basic way. Consequently little is said about the nature, extent, or significance of inferential knowledge of God, or, more precisely, the epistemic function of theistic arguments. Although Plantinga concedes in a few places in WCB that theistic arguments can confer warrant on theistic belief (WCB, pp. 179, 258), from the rather sparse and undeveloped comments at this juncture it appears that it is not essential, or at least not central, to the epistemological model he presents. But it might be worth considering the avenues open to Plantinga here, and which might retrospectively call for modifications in the model he presents.

 

In this paper I hope to provide some suggestions as to how Plantinga could have developed his model of properly basic theistic belief in a way that would assign a more explicit and prominent role to inferential reasoning vis-à-vis our putative natural knowledge of God. These suggestions will arise by way of a critique of Plantinga’s use of the Reformed tradition in the development of his epistemological model. In both WCB and in his earlier publications, Plantinga has drawn considerably on the Reformed tradition in his thinking about the knowledge of God, specifically utilising theologians such as John Calvin, Abraham Kuyper, and Herman Bavinck. However, Plantinga has revised the Reformed view on our natural knowledge of God in some crucial ways, and as a result of these revisions an important function for natural theology in the epistemology of theistic belief has been marginalised, if not eliminated altogether.

 

I. The Sensus Divinitatis and Plantinga’s Revision

 

In Chapter 6 of WCB Plantinga proposes the A/C (Aquinas/Calvin) model of warranted theistic belief. According to this model, humans are created with a disposition to form various theistic beliefs in wide variety of experiential circumstances, from the sight of the starry night sky to the sound of a Mozart Symphony. In much the same way that sensory perceptual experiences provide the circumstances that trigger our disposition to form various sensory perceptual beliefs, there are widely realised experiential circumstances that spontaneously trigger an innate disposition to form various theistic beliefs. Such beliefs are formed in a basic way, not by logical inference from other beliefs taken as evidence for theistic propositions. In this way, theistic belief shares an important similarity to sensory perceptual, memorial, testimonial, and a priori beliefs. Plantinga claims that this account is a philosophical development of insights found in the Reformed theological tradition, originating with John Calvin’s discussion of the sensus divinitatis (sense of divinity) in the early chapters of Book I of the Institutes of the Christian Religion. Although Plantinga’s model of properly basic theistic belief has several philosophical merits, it deviates in some important ways from a common Reformed view of natural knowledge of God.

 

When discussing the natural knowledge of God, it has been commonplace in the Reformed tradition to distinguish between the implanted knowledge of God (cognitio Dei insita) and the acquired knowledge of God (cognitio Dei acquisita).[3] The distinction arose among Reformed theologians shortly after Calvin in their attempt to elucidate and develop Calvin’s account of the natural knowledge of God. In Chapter 3 of book I of the Institutes, Calvin articulates his doctrine of the sensus divinitatis, an immediate or non-inferential knowledge of God that arises spontaneously in the human mind.[4] But in Chapter 5 of book I of the Institutes Calvin affirms a knowledge of God grounded in the manifestation or evidence of God’s perfections in creation. “Not only has God sowed in men’s minds that seed of religion of which we have spoken but revealed himself and daily discloses himself in the whole workmanship of the universe” (Institutes 1.5.1).[5] Although there has been some dispute in Reformed circles as to how exactly we should understand the distinction, if any, Calvin is drawing here, Reformed theologians have traditionally understood Calvin to be at least implicitly distinguishing between two distinct modes of natural knowledge of God, the sensus divinitatis and a knowledge of God associated with or derived from the general revelation of God in the created order.[6] This distinction became deeply entrenched in the period of Protestant scholasticism under the categories of implanted and acquired natural knowledge of God, the former being non-inferential and the latter inferential. Equally important, though, there has also been a tendency to regard these two modes of knowledge as differing in their content or scope. For instance, according to Charles Hodge, the implanted or immediate knowledge of God is simply “the general sense of a Being on whom we are dependent, and to whom we are responsible”, whereas analysis and inference aims “to show what that Being is”.[7] Again, Calvin may be regarded as the genesis of the basic insight here. The sense of divinity appears to be a somewhat vague religious sense or awareness, a sense that there is some God and that he ought to be worshipped. By contrast, the knowledge of God acquired from reflection on the created order provides, at least in principle, a variety of details about the nature of God.[8] I will consider this in greater detail below.

 

At first glance, Plantinga’s account revises this traditional view in several ways. According to Plantinga (WCB, p. 174), the sensus divinitatis produces a broad range of beliefs about God: there is a God, God is great, God is creator, God should be thanked and praised, God disapproves of what I have done, God forgives me for what I have done, God hears my prayer, God can deliver me out of this trial, God is speaking to me, etc. Many of Plantinga’s basic theistic beliefs involve the recognition of various divine attributes (power, knowledge, goodness, for example) and a range of beliefs with personal indexicals (such as God is speaking to me now). But in Calvin’s treatment of the sensus divnitatis little if anything is said about these sorts of highly specified theistic beliefs. Secondly, Plantinga takes Calvin’s Institutes 1.5 “evidences” to be circumstances in which the sensus divinitatis is triggered and various theistic beliefs are formed immediately, without any inferential reasoning, in much the same way that our sensory perceptual or memory beliefs are formed (WCB, pp. 175–176). Furthermore, rather than treating the sense of divinity as a knowledge of God itself (as Calvin does), for Plantinga it is simply a faculty or mechanism utilised to produce theistic belief and knowledge when stimulated by the Institutes 1.5 evidences. The innate or implanted knowledge of God is replaced by an innate “capacity” to acquire knowledge of God in a basic way, in circumstances that correspond to an experience of the Institutes 1.5 “evidences”. The grounds for acquired knowledge of God become the mere occasion for triggering the innate capacity. Plantinga thus loses the Reformed distinction between the implanted and acquired knowledge of God. Two distinct sources of theistic knowledge become two different elements involved in a single process of belief formation and knowledge.

 

II. The Cognitio Dei Acquisita and Other Minds

 

In losing the Reformed distinction between implanted and acquired natural knowledge of God, Plantinga’s revision seems to lose a common Reformed basis for natural, inferential knowledge of God. Limits on the scope of properly basic theistic beliefs enlarge the cognitive space for inferential knowledge of God. The latter function as a supplement to the former by filling out and extending some minimal truth about God grasped immediately by the human mind. Conversely, by maximising or enlarging the scope of what is given by way of the sensus divinitatis, as Plantinga does, one reduces the importance of the inferential character of our natural knowledge of God. Such a move does not undermine the project of natural theology per se. Plantinga can certainly maintain, and in fact does, that there are good theistic arguments and they are important to Christian apologetics and philosophical theology. The criticism here is that an important epistemic function of theistic arguments or evidences has been weakened, the necessity of such arguments or evidences for the warranted status of a range of theistic beliefs that form an essential part of the natural knowledge of God. Of course Plantinga could still argue, and in fact does, that natural theology can contribute and even be necessary to the warrant of theistic beliefs in various circumstances for some people, especially given the acquisition of defeaters.[9] So the argument is not even that, on Plantinga’s model, theistic arguments have no epistemic function. The present argument suggests a stronger epistemic function, a more radical proposal. On the model I propose here, the sense of divinity does not provide the range of natural knowledge of God Plantinga suggests. So the warrant of these beliefs will likely depend on inference.

 

Let’s consider how this would work in greater detail.

 

Clearly, a crucial question is the scope of the propositional content associated with the two modes of knowledge under discussion. Reformed theologians do not speak with one voice concerning the exact content of the implanted knowledge of God, and space does not permit any detailed analysis of this. As already stated, for Calvin the sensus divinitatis is simply the awareness that there is some God and that he ought to be worshipped. Since Calvin takes idolatry to be evidence of the existence of a sense of divinity, this awareness of God is logically consistent with a great deal of fundamentally false beliefs about God. Hence, the sense of divinity must be sufficiently general. But in both The Institutes and in his commentaries on the Psalms, Acts, and Romans, Calvin argues that various divine attributes can in principle be known by inference from features of the created order. Among such attributes are God’s goodness, wisdom, justice, power, mercy, and eternity.[10] These more detailed descriptions of God are never associated with the sense of divinity itself, but left rather to the development of the primordial awareness of a supreme being through the process of reasoning and reflection.

 

What Calvin says is more explicitly articulated in later Reformed theologians. As already noted, according to Charles Hodge, the implanted knowledge of God is simply “the general sense of a being on whom we are dependent, and to whom we are responsible”.[11] The knowledge of God’s personality, moral attributes, and intelligence arise only upon observation of the created world and reflection. The function of the theistic arguments, as Hodge sees it, is not simply to prove that God exists, but to inform us about the nature of God.[12] Samuel Harris maintained a similar distinction: “By rational intuition man knows that absolute Being exists; his knowledge of what it is, is progressive with his progressive knowledge of man and nature”.[13] Augustus Strong also argued, “a consideration of these [theistic] arguments may also serve to explicate the contents of an intuition which has remained obscure and only half conscious for lack of reflection”.[14] According to William Shedd, theistic arguments “assist the development of the idea of God, and contain a scientific analysis of man’s natural consciousness of the deity”.[15] By limiting the scope of what can be immediately known about God, these Reformed theologians left important cognitive space for an inferential, natural knowledge of God.

 

We may compare the current proposal to our epistemic situation in relation to beliefs we have about other minds. Plantinga and other Reformed thinkers have frequently argued that belief in other minds is relevantly similar to belief in God.[16] It is basic and properly so. However, in the case of belief in the existence of other minds presumably what is immediate is my belief that there are other minds or perhaps my belief that ‘here’ or ‘there’ is a mind (connected with the body I see before me). In neither case is anything specified about the characteristics of other minds. One might argue, therefore, that it is only by inference that I acquire knowledge about the characteristics of other minds. So perhaps even knowing that one’s friend or wife exists requires inference of some sort, for identifying minds with these properties seems to require inference. I know that Mr. Gush is my friend on the basis of my knowledge of what is necessary and sufficient for friendship and that my relationship with Mr. Gush satisfies these conditions. The knowledge is inferential. Perhaps I directly know that there are other minds, but on what basis do I know that ‘this bloke’ is my friend, ‘that lady’ my wife, and ‘this man’ a colleague at Saint Michael’s College? Similarly, inference would seem to play an important role in the knowledge of propositions involving more specific descriptions of the characters, physical properties, and mental states of people. True, in all these cases I must make the assumption that there are other minds and that they are somehow connected to the bodies that appear to and interact with me. But unless I did this and made certain inferences, what could I know about the other minds whose existence I grasp in some immediate way? Precious little I should think.

 

If we restrict our attention solely to the similarity between belief in the existence of other minds and belief in the existence of God, we may lose sight of the other side of the analogy. Just as our knowledge about the nature of other minds depends largely on inference, so also our knowledge of the nature of God depends largely on inference. An epistemology of religious belief must be concerned not only with how we know that there is a God but also with how we know various other propositions about the nature of God, for instance that he is omniscient, omnipotent, omnibenevolent, eternal, immutable, necessary, and so on. Moreover, when such crucial epistemological details are introduced it is clear that for some people even the belief there is a God may depend considerably on inference.[17] The proposition expressed by the sentence there is a God depends on what is meant by ‘God’, and the epistemic devil is in the conceptual details.

 

There are two important qualifications to my argument here though.

 

First, many beliefs about other minds and God can be accepted in a psychologically basic way. One could accept a variety of beliefs about other minds in a psychologically basic way via testimony, and presumably this would also be true with respect to many theistic beliefs. For example, I might accept on the testimony of a pastor or theologian that God is timelessly eternal, in much the same way that I accept on the testimony of a close friend that Mr. Gush is a virtuous person. But my basic belief in each case would be warranted via testimony only if these beliefs were warranted for the testifier. But why are they warranted for the testifier? This will set off a regress of warrant transfer for the relevant belief that will eventually require some sort of inferentially warranted belief in the target proposition. So there must be inferential warrant somewhere down the line in the ancestry of the belief. Hence, even a warranted basic belief in this situation will have propositional evidence available for it, and it would not otherwise be warranted. Hence, theistic beliefs of this sort, as well as various beliefs about other minds, would be similar to what Stephen Wykstra calls “evidence-essential” beliefs, beliefs for which there must be evidence available, even if a given person does not accept it on the basis of such evidence.[18]

 

Secondly, if Plantinga’s extended model of warranted Christian belief is roughly correct, then many Christian beliefs about God, including those that can also be known by our natural cognitive powers, will have warrant in a basic way for the Christian. The Scriptures declare God’s goodness, mercy, knowledge, providential control of the world, etc. On Plantinga’s extended model, belief in these truths is by way of the internal instigation of the Holy Spirit. Although inference plays an important role in the development of the Christian’s knowledge of God, it looks like it will not be needed to know many of the theistic propositions that qua natural knowledge of God depend on inference. But it is only the latter that interests me in the present paper. What the present account implies is an important difference between the unregenerate person’s knowledge of God and the Christian’s knowledge of God even when it is the same theistic proposition under consideration. The Christian can know these in a basic way on the basis of Scripture and the testimony of the Holy Spirit. The unregenerate is in a significantly different epistemic position. Furthermore, given the noetic effects of sin, the present account may also imply that the unregenerate person often does not in fact know what can in principle be known about God by reason and which is known by faith by the Christian.

 

So I take it that the present account of the necessity of inferential knowledge of God must be qualified in the ways outlined above. Thus, even if we suppose that there is some immediate, natural knowledge of God’s existence, the Reformed tradition seems to regard such knowledge as quite minimal. The development and extension of this knowledge is left to inference, subject to the above qualifications. In this context, the philosophical project of natural theology will be the attempt to codify and formally articulate what can, in principle, be known about God by inference from reason and observation.[19]

 

III. Inferential Warrant and Plantinga’s Alternate Model

 

I think that the above proposal also addresses several, related concerns that Plantinga expresses about inferential, natural knowledge of God, from which he derives additional support for the advantages of his own model. Plantinga’s main concern with taking Calvin’s Institutes 1.5 evidences as suggestive of inferential knowledge of God is that as arguments they look quite weak and inadequate to ground any warranted theistic belief. Plantinga writes: “It isn’t that one beholds the night sky, notes that it is grand, and concludes that there must be such a person as God: an argument like that would be ridiculously weak” (WCB, p. 175). Plantinga’s basic argument seems to be that Calvin’s account of our natural knowledge of God is more philosophically plausible if we adopt the sort of model Plantinga is proposing. Put more technically, Plantinga’s argument is that the epistemic conditional probability of the existence of God on the evidence Calvin cites and relevant background knowledge would be low. Hence, it looks like theistic belief will not get much by way of warrant this way.

 

Even if we suppose that Plantinga is correct here, there is an important assumption being made in the analysis. When Plantinga introduces the inferential interpretation of Calvin, he takes the target proposition, supported by the relevant evidence, to be ‘God exists’. Reasonably enough, the background knowledge will exclude theistic propositions. But on the interpretation of Calvin I have argued, the target proposition is not ‘God exists,’ but some other proposition about the nature of God, which will in turn serve to extend the content of an original, immediate knowledge of God. The conditional epistemic probability that ‘God exists’ given evidence E and background knowledge K (which excludes theistic beliefs) will be very different from the conditional epistemic probability that ‘God is provident’ or ‘God is a personal, intelligent being’ given E and K, where K includes knowledge that there is some God. Again we can draw on the analogy from other minds. The conditional probability of ‘this here is another mind’ given my observations of the behaviour of local physical bodies (and relevant background knowledge) may be very low. But suppose that what is at issue is the conditional epistemic probability that Mr. Gush is my friend or that my wife is a virtuous woman. The conditional probability of these propositions may be very high given the same evidence in conjunction with background knowledge now revised to include my knowledge that that there are other minds and that they are connected to certain local bodies and behaviour.

 

Given the discussion on the sensus divinitatis antecedent to the elaboration of the manifestation of God in creation, it is reasonably clear that Calvin does not intend the Institutes 1.5 evidences to be the grounds for de novo belief in or knowledge of God’s existence. Theistic arguments always presuppose some prior sense of divinity. So theistic arguments or inferences aim to extend and develop a rudimentary, antecedent knowledge of God, in much the same way that inference develops and extends our minimal knowledge of ‘this’ or ‘that’ other mind. Put otherwise, argument or inference is not the sole ground for our natural knowledge of God as a whole, and theistic arguments carry the logical force they do for their respective conclusions only because there is an antecedent sense of divinity in each person.

 

There is, of course, a potential objection to my critical comments on Plantinga lurking in the pages of WCB. In Chapter 6 of WCB, Plantinga does leave open the possibility of construing our natural knowledge of God as inferential, and he presents an alternate inferential model as a reasonable interpretation of Calvin. Plantinga argues that the role of the sensus divinitatis might be to enable a person to see the truth of a crucial premise in a simple sort of theistic argument. For example, perhaps the sensus divinitatis enables one to see the truth of the premise that ‘the heavens can be gloriously beautiful only if God has created them’ (WCB, p. 176). In this case, the belief that God created the heavens would be inferred from this explanatory conditional in conjunction with the belief that the heavens are gloriously beautiful. Hence, it would seem that Plantinga does not eliminate the traditional Reformed notion of acquired, inferential knowledge of God after all.

 

There are two important observations in this suggestion by Plantinga. First, we need not think of inferential knowledge as requiring the actual giving of an argument or even constructing one explicitly in one’s mind. As I have argued elsewhere, much of our inferential knowledge probably proceeds in a temporally immediate fashion without a conscious process of inferring one proposition from another.[20] Secondly, Calvin’s notion of inferential knowledge of God is largely a matter of God’s existence explaining features of the world. Hence, the inferences are largely explanatory in nature.

 

However, Plantinga’s alternate model still differs significantly from the proposal in this paper. First, the function of the sensus divinitatis is different. Rather than constituting a basic awareness of God, it is still being conceived of as a faculty that produces beliefs of a certain sort, and in this case producing beliefs of a very different sort than I think Calvin and the Reformed tradition have associated with the sensus divinitatis. Secondly, Plantinga still manages to lose the distinction between the implanted and acquired knowledge of God, though this time it is the immediate knowledge of God that is edged out. In Plantinga’s alternate model, the sensus divinitatis is not nor by itself yields any knowledge of God. It simply yields knowledge of certain conditional propositions that operate in explanatory inferences that lead to theistic knowledge. Lastly, and I think this is crucial, the alternate model at best obscures the central claim of this paper, namely that the acquired knowledge of God is an extension or development of a minimal immediate knowledge of God. The function of inferential knowledge of God is primarily to reach a fuller notion of the being whose existence is vaguely intuited or grasped immediately. Of course, due to sin few will actually make much progress in such knowledge. This is the other side of the epistemic coin. But Calvin holds such people accountable for lacking such knowledge since they nonetheless possess a sense of divinity and ought to know God in a deeper way given the evidences they have all around them.

 

So we seem left with three possible models for our natural knowledge of God. In Plantinga’s main model, the scope of immediate natural knowledge of God undermines the importance of inferential natural knowledge of God. In his alternate model, inferential natural knowledge of God becomes significant, but this knowledge is not a development of a pre-existing immediate natural knowledge of God. In fact, the immediate knowledge of God seems to be eliminated on this account. Moreover, since the sensus divinitatis produces, presumably in a basic way, the premise that links observational phenomena with God as the explanans, it isn’t clear how the philosophical project of natural theology can be developed given this model. Lastly, there is the model I have presented in this paper. In contrast to the Plantingian models, this model represents a traditional Reformed view of the natural knowledge of God. By placing limits on the scope of immediate knowledge of God, inferential knowledge of God takes on a specific role of extending and developing a very rudimentary immediate knowledge of God. The philosophical project of natural theology will then be concerned with formally articulating the logic of this inferential knowledge of God.

 

IV. Conclusion

 

 

Unlike many of his Reformed predecessors, Plantinga’s account of our natural knowledge of God does without the long-standing Reformed distinction between the implanted and acquired knowledge of God, as well as the related difference in content between them. Although Plantinga’s revision has strengthened the apologetic defence of the positive epistemic status of theistic belief against various evidentialist objections, it has weakened an interesting, important, and strong epistemic function of theistic arguments or evidences that has been available in the Reformed tradition. Some may judge this an acceptable trade off. But an interesting future challenge to Reformed philosophers would be to maintain the sound apologetic against the undesirable elements of evidentialism, while also developing a stronger role for inference with respect to our knowledge of God, natural and otherwise. In this paper, I have drawn on the Reformed tradition to present one model of how this can be done, specifically with respect to the natural knowledge of God. I suspect that Plantinga will welcome some of these suggestions, whether as a critical engagement of his current way of thinking about theistic knowledge or as suggestive of ways of modifying and extending the A/C model presented in WCB. In short, the general recommendation would be to set limits on proper basicality (with respect to warrant) to make room for inferential knowledge of God. I haven’t proposed any detailed account of just where we should draw this line. I’ll leave this for future reflection and dialogue. Lastly, I have no doubt that the project of natural theology may exist harmoniously with the claims of Plantinga’s Reformed epistemology as they are developed in WCB. The present recommendation represents one way of strengthening the connection between them. Perhaps it will generate further dialogue at a crossroad somewhere between Jerusalem and Athens.[21]
