Minimal requirements for a divine-command theory of moral obligation
It is uncontroversial that Jesus' summary of the moral law in the Gospels as a two-part command to love is central to Christian ethics. It is no small detail of this teaching that love for God and neighbour is the object of a command. Kierkegaard certainly recognizes the importance of the commanded nature of Christian love, as the chapter from Works of Love entitled ‘You shall love’ clearly demonstrates.Footnote 1 What is unclear is what conclusions should be drawn from these observations. Philip L. QuinnFootnote 2 and C. Stephen EvansFootnote 3 both argue that we can find in this discussion evidence that Kierkegaard himself endorses a divine-command ethic of some sort. In order to assess their arguments, we first need to be clear about what, exactly, a divine-command theory is.
Quinn and Evans agree that a divine-command theory of moral obligation [henceforth: DCT] must hold, minimally, (1) that divine commands and moral requirements are coextensive, and (2) that there is a metaphysically asymmetrical relationship between the two, such that divine commands are in some sense prior to moral requirements and moral requirements in some way depend on divine commands.Footnote 4 Evans formulates these two conditions as follows:
A divine command theory of moral obligation, as I shall understand the term, is therefore committed to the following two propositions: (1) Any action God (understood as a perfectly good, all-powerful, and all-knowing Creator) commands his human creatures to do is morally obligatory for them. (2) Any action that is morally obligatory for humans has the status of moral obligation because God commands it.Footnote 5
Though Evans is right that a divine-command theorist is committed to these propositions, a minimal DCT must assert something stronger: it must hold that, necessarily, any action that God commands is morally obligatory and, necessarily, any action that is morally obligatory has this status because God commands it. Otherwise, the view will not entail counterfactual propositions of the form, if God (counterfactually) had commanded p, then p would be obligatory – a set of claims the divine-command theorist surely wants to endorse. The asymmetrical relation clause also needs to be strengthened as follows: necessarily, there is a metaphysically asymmetrical relationship between divine commands and moral obligations such that the latter depend on the former. This ensures both that the relation between divine commands and moral requirements is one of dependency of the latter on the former and that it could not be otherwise. Let us, then, strengthen the minimal version of DCT under discussion in these ways.
Thus modified, the co-extensiveness thesis expresses a necessary bi-conditional – a material equivalence between divine commands and moral obligations that holds in all possible worlds: necessarily, p is morally obligatory if and only if God commands that p. It will be helpful for our purposes to separate the bi-conditional into its constituent parts and to name each part for ease of reference. Let ‘the necessity clause’ refer to the proposition that, necessarily, p is morally obligatory only if God commands that p. The necessity clause expresses that, necessarily, only those things that God commands are morally required. This entails that nothing is morally required except what God commands, i.e. that any action that lacks the property of being divinely commanded also lacks the property of being morally obligatory. Thus, divine commands constitute the only ground of moral obligation that is possibly sufficient.Footnote 6 Let ‘the sufficiency clause’ refer to the proposition that, necessarily, p is morally obligatory if God commands that p. The sufficiency clause expresses that, necessarily, everything God commands is morally obligatory (in the world in which He commands it); nothing is required in addition to God's commanding p to make p obligatory.Footnote 7 The difference between the two clauses is important because, I will argue, Kierkegaard's writings provide support only for one of them.
Quinn on Kierkegaard and divine-command ethics
Quinn's argument for a divine-command ethic in Works of Love begins with the observation that, for Kierkegaard, Christian love for the neighbour – agape love – is commanded by God, and its being commanded by God suffices to make it obligatory:
In the religious tradition of Jesus and his hearers, it is taken for granted that divine commands give rise to obligations, and so an obligatory love would in that tradition naturally be represented as commanded by a divine lawgiver. It is, then, no accident that the love of neighbor the Gospels propose to us is, as Soren [sic] Kierkegaard says, a “commanded love.”Footnote 8
Quinn identifies three primary reasons why, according to Kierkegaard, love of neighbour must be commanded and thus made obligatory. First, ‘only love which is obligatory can be extensive enough in scope to embrace absolutely anyone without distinction’.Footnote 9 In the absence of the command, love is based on preference and thus extends only to those for whom we feel some affection or those to whom we have some special tie. Second, ‘only a love which is obligatory can be invulnerable to changes in its object’.Footnote 10 Loves based on preference are always subject to change: they can begin to wane or be extinguished completely if some change occurs in one (or both) of the lovers that makes him or her seem no longer lovely to the other. And finally, it is necessary for neighbour love to be commanded by God in order to provide us with ‘backup motivation’Footnote 11 – a constant and reliable source of motivation to love the neighbour when there is insufficient or no natural inclination to do so:
For most of us most of the time, love of neighbor is not an attractive goal, and, if it were optional or supererogatory, we simply would not pursue it. To get us to have such love, it must be presented to us as an obligatory love with the feel of something that represents a curb or check on our natural desires, inclinations, and predilections.Footnote 12
Quinn repeats his basic argument about Kierkegaard's unique understanding of the radical demands of neighbour love in at least five articles,Footnote 13 and in each of these, the context implies that Quinn takes these arguments to be evidence of Kierkegaard's divine-command ethic.Footnote 14 Each time, Quinn expresses his view that ‘no Christian thinker has seen with greater clarity than [Kierkegaard] just how radical the demands of love of neighbor really are’,Footnote 15 and, after making observations such as the ones above, he proceeds to unpack what the concept of neighbour love entails for Kierkegaard. His exposition of Kierkegaard's concept of neighbour love seems to me successful for the most part. The problem, however, is that it is never clear why Quinn thinks that Kierkegaard's claims about neighbour love add up to a divine-command ethic. The textual evidence Quinn cites supports only the conclusion that Kierkegaard endorses some view of moral obligation compatible with the claim that God's commands are sufficient to impose moral obligations. Since there are a number of theistic ethical theories that are compatible with the sufficiency clause, this gives us no reason to think Kierkegaard favours DCT, in particular. The inference from such evidence to the conclusion that Kierkegaard advocates DCT is fallacious. In order to support the DCT reading of Works of Love, Quinn would need to provide some textual evidence that Kierkegaard endorses the necessity clause, as well. He offers no evidence of this – and, a fortiori, no evidence that even a minimal version of DCT is advocated in Works of Love.Footnote 16
This is, as far as I can tell, the most serious difficulty for Quinn's reading of Kierkegaard. But there are other difficulties as well. In much of his discussion of Kierkegaard, Quinn seems to confuse DCT with a theory of moral motivation. Quinn repeatedly emphasizes the need for neighbour love to be commanded in order to motivate the Christian to love the neighbour even when the neighbour is perceived to be unlovely. The command is a source of motivation that gives one a reason to love even when one's natural inclinations are to hate, ignore, or simply fail to love the neighbour as one ought. But even if it is true that we need the command for this purpose, taking this fact to support a divine-command reading of Kierkegaard conflates a thesis about moral motivation with a thesis about the ontological basis of moral obligation. It is one thing to claim that divine commands are needed to motivate us to fulfil our moral obligations; it is another to claim that the metaphysical basis of moral obligation is tied essentially to divine commands. The two claims are logically distinct, and neither obviously entails the other.
I see two reasonable ways of interpreting Quinn on this point, though on either reading, Quinn's view is problematic. On the one hand, Quinn might be claiming that, for any action A, a duty to A binds an agent S only if S feels some inclination not to A. On this view, duties exist only insofar as there is some conflict between what God wants us to do and what we naturally are inclined to do. Thus God issues commands – and thereby brings it about that we are morally obligated – whenever He wants to give us an overriding reason to act in some way that we otherwise would not. This is one way of understanding the following passage:
But the image of God, who is perfectly good, is presumably a mark that renders all who bear it lovable. If one can discern it in another, one can give the other loving care in virtue of and on account of the other's possession of it. … [I]f Kierkegaard is right about there being an inner glory in each of us, loving care can be given to anyone, absolutely anyone, out of affection for it if one can but see it. … It must be emphasized, however, that even if Kierkegaard is right about there being an inner glory in each of us, many will still be thrust back by the command to love the neighbor. Some will think it foolish to look for the image of God in all those they encounter; others are unlikely to see it no matter how hard they look …. Moreover, the image of God is often too faintly perceived to be motivationally sufficient for those works of love that demand great sacrifice. So ordinary Christians need to be able to trust to [sic] the ‘Thou shall’ of the command for backup motivation. They will have to appeal to the motive of duty on many occasions as a substitute for or a supplement to the motives provided by perceived inner glory.Footnote 17
What Quinn seems to be saying in these passages is that once we come to see the image of God in the neighbour, we can come to love the neighbour (‘give the other loving care’) on the basis of finding the neighbour lovely – in the deepest sense rather than a superficial sense – rather than having to rely on the ‘backup motivation’ of the command to love.
It might not be immediately obvious why this view is problematic. To make the difficulty clear, consider the following question: would we have a duty to love the neighbour if our natural inclination (at all times) were to love the neighbour? In the passage above, Quinn suggests that if we could see the image of God in the neighbour at all times – which, presumably, we always could do if not for the blinding effects of sin and our fallen nature – then there would be no need, motivationally speaking, to make loving the neighbour a duty, and thus no need for God to issue a command to love the neighbour. In such a case, God would not issue the command, so there would be no duty to love the neighbour. But this seems mistaken. There is a difference between (1) agent S not needing action A to be a duty in order for S to be motivated to A, and (2) A's not being a duty for S. While it is plausible that (1) could, in some circumstances, apply to loving the neighbour, it is not plausible, I think, that (2) could.
The argument for why loving the neighbour could not fail to be a duty is this: if, as Quinn's own claims about the neighbour's essential nature suggest, agape love is the only proper response to the neighbour as a fellow creature of God who bears His image, then it seems we have another source of duty to love the neighbour in addition to the divine command to do so. We have an obligation to love the neighbour because of the kind of being the neighbour is. We would have this duty even if, due to our moral and religious perception's being so acute and our character's being so virtuous that we always saw the neighbour as lovely and thus loved the neighbour without special moral effort, God had not issued a command to love the neighbour. Thus (1) and (2) are not equivalent. It may be that, in the actual world, because of our sinful natures, it is necessary for God to issue a divine command to love the neighbour in order for us to know that this is our duty, and it may be that divine commands are necessary to motivate us to uphold this duty, but the duty to love the neighbour exists prior to the command, in virtue of the fact that the neighbour is both a creation of God and a being who bears the imago Dei.Footnote 18
In fact, on this first interpretation, the various claims Quinn makes about the relation between duty and motivation, when combined, lead to paradox. As previously discussed, what characterizes the first interpretation of Quinn is his endorsement of:
(1) For any action A, an agent S has a duty to A only if S has some inclination not to A.
But elsewhere Quinn endorses (what he takes to be) Kierkegaard's view that:
(2) We are divinely commanded – and thus have a duty – to love ‘affectionately’.Footnote 19
(Here ‘affection’ is being used in the sense of ‘tender concern’, ‘attentive regard’, ‘affectionate sensitivity to the individual character of the recipient’.)Footnote 20 And yet, Quinn also claims that:
(3) We are commanded to love the neighbour because loving the neighbour is an act that ‘does not spontaneously engage [our] affections’.Footnote 21
and that,
(4) A love that is motivated by duty is not ‘a matter of feelings’ and can ‘exist and persist independent of feelings, though it need not do so’.Footnote 22
There are a number of ways in which these claims come into conflict with one another. First, (4) is in tension with (2), because a love that is not a matter of feelings, and can exist and persist independently of feelings, is not an affectionate love in the sense in question. Second, the combination of (1) and (2) apparently leads to the following paradoxical conclusion: we have a duty that, if perfectly upheld, renders the duty no longer a duty. (2) claims that we have a duty to love the neighbour affectionately, and (3) implies that the reason this is a duty is that we are not naturally inclined to do it. But it is plausible that one could uphold this duty perfectly – that one could perfectly love the neighbour affectionately in the sense of loving her with tender concern, attentive regard, and sensitivity to the individual character of the neighbour – only if one loved the neighbour out of a pure character. Presumably, an individual's character would be pure (perfectly virtuous) only if she loved the other affectionately without inner conflict – that is, only if her natural inclinations were to love the neighbour. But if this is right, then if one perfectly upheld the duty cited in (2), it would cease to be a duty, because, according to (1), one cannot have a duty to do what one has no inclination not to do. This implies that one cannot fulfil one's duty by perfectly loving the neighbour – a view that, while perhaps not logically contradictory, certainly is paradoxical. Moral requirements of this type ordinarily are not thought to be the sorts of things that cease to be requirements if they are perfectly upheld.
These problems suggest that we should look for another interpretation of Quinn on the issue of the relation between duty and moral motivation. A second reasonable interpretation is that Quinn thinks the duty to love the neighbour remains for an agent even when (ideally) that agent's character has been perfected. On this reading, Quinn is claiming that in this perfected state, the agent no longer relies on the motivation of the duty to love the neighbour; instead, she loves the neighbour because she sees the ‘inner glory’ – the imago Dei – in the neighbour and thus recognizes that the neighbour is intrinsically worthy of being loved. The duty to love the neighbour remains even though it is motivationally superfluous. The following passage provides some textual support for this interpretation:
Saintly exemplars such as Mother Teresa … show us that we might, if we would but try, find something glorious in anyone and as a result might come to perform works of love not merely out of obedience to the divine command but also in affectionate response to the glory perceived in the one for whom the works are performed. This, I take it, would be the perfection of Christian love for the neighbor.Footnote 23
This is, I think, a more reasonable view, and it avoids many of the problems just discussed. But on this reading, what is important for the issue of moral motivation is that neighbour love is obligatory, not that it is commanded. What is important is that we have a backup motivation to love the neighbour when we lack any natural inclination to do so. But if neighbour love is obligatory, and if we know it to be such, then we have this backup motivation; it does not matter why it is obligatory. Thus, the motivational importance of the duty to love provides no support whatsoever to DCT over other ethical theories on which neighbour love is obligatory. To claim otherwise is to beg the question in favour of DCT: it is to assume that, since neighbour love must be obligatory to provide us with sufficient motivation to practise it, it must be divinely commanded. This is simply to assume that the only source of duty is divine commands. Certainly, the proponent of DCT is committed to this view (the necessity clause), but simply to assume its truth is not to provide evidence for DCT. So, once again, even if Quinn is right in thinking that Kierkegaard sees that it is a practical necessity for fallen creatures that love of neighbour be a duty, this provides no evidence for thinking that Kierkegaard endorses DCT.
A final problem with Quinn's reading of Kierkegaard is that it seems at times to conflate DCT with what is sometimes called ‘the weak dependency thesis’: the thesis that, as Avi Sagi and Daniel Statman put it, ‘human beings, because of their flaws, can neither attain moral knowledge nor behave in moral ways unless assisted by God’.Footnote 24 The weak dependency thesis resembles DCT in giving divine commands a central role; the crucial difference, however, is that the role is epistemological and/or motivational rather than ontological. Quinn writes,
Christians are, I take it, expected to be confident that there is something loveable about each human person, even if they do not see what it is, because God loves all his human creatures. But perhaps only those who are well advanced in the practice of works of love should hope to be blessed with a growth in the brightness of eternity's light that will enable them to see steadily what makes some of their neighbors worthy of love.Footnote 25
Coming back to a point discussed earlier, if it is the image of God in the other that makes the other ‘worthy of love’, then this suggests that we have a duty to love the other in virtue of this feature of the other's essential nature, independent of any divine command to do so. Nevertheless, it may be necessary for God to command us to love the neighbour in order for us to recognize this duty – whether because of our fallen nature, the noetic effects of sin, our own personal moral immaturity, or whatever. Divine commands are, on this model, an essential component of human moral development; without them, we would be blind to our obligations, or, at the very least, confused about the extent of our duties and about what it is that we are obliged to do in some cases. None of this, however, implies the stronger dependency thesis according to which all moral obligations owe their ontological status to God's activity of issuing commands. In fact, if the neighbour's essential nature as bearer of the imago Dei itself imposes the duty to love, then this stronger dependency thesis is false: at least some duties owe their status as duties to certain features of creation rather than to their being commanded by God.
Evans on Kierkegaard and divine-command theory
Though Quinn initiated the discussion of Kierkegaard's relation to divine-command theory, the most nuanced and developed version of the divine-command reading of Kierkegaard, to date, is presented by C. Stephen Evans in Kierkegaard's Ethic of Love. Evans attempts to synthesize the motivational and metaphysical aspects of DCT by developing ‘a divine command theory of ethics that can incorporate some of the insights of a human nature theory of moral obligation’.Footnote 26 By a ‘human nature theory’, Evans means a theory that accounts for the grounds of moral obligation in terms of a teleology of the natural order – one that focuses especially on the conditions for human flourishing. The ethic Evans finds in Kierkegaard's writings synthesizes DCT and certain aspects of a human nature theory by holding that moral obligations are grounded in divine commands, but God, being essentially loving, issues these commands not arbitrarily, but rather with the intent of promoting our own individual and/or collective flourishing.
The idea that our relation to God is a crucial part of human flourishing has a long history. Evans notes that within the Christian tradition, ‘it has generally been taught that such a relation is the highest good that is possible for a human person. It follows very plausibly from this that a need for such a relationship is a constituent of human nature.’Footnote 27 As our just and loving Creator, God is owed our love, respect, gratitude, and obedience. But there is an important difference between the ethic Evans defends and a fully fledged human-nature theory, such as that often found in ethical theories inspired by Thomism:
God's commands can be understood as fitting our human nature and as being directed to our happiness. This divine command theory, however, differs from a human nature theory in claiming that moral obligations do not follow directly from human nature alone. On such a view morality fits our human nature, but one cannot deduce our moral duties simply from knowledge of human nature.Footnote 28
For Evans's Kierkegaard, God's plan for each person is unique, and each individual's highest flourishing is attained by becoming the particular self that God intends that person to be. An individual becomes the self God intends through a process of character-formation guided by obedience to the commands God issues to that person. What God commands of each of us, perhaps most fundamentally, is that we become more loving. By truly loving God and our neighbour, we become more like God, whose very nature is love.Footnote 29 This fundamental command is one that is issued to – and thus binding upon – all persons.
However, God also may impose individual obligations by issuing certain commands to an individual that He issues to no-one else. He may, for example, command me and only me to take some course of action; in this way, an action that might be morally neutral for anyone else becomes obligatory for me. This opens up the possibility that God has for each of us a particular vocation or calling.Footnote 30 Kierkegaard writes,
But this I do believe (and I will gladly listen to any objection, although I will not believe it) that at each man's birth there comes into being an eternal vocation [evig Bestemmelse] for him, expressly for him. To be true to himself in relation to this eternal vocation is the highest thing a man can practice.Footnote 31
The concept of personal vocation is most at home in an ethic in which divine commands play a central role. God can, for example, give one certain abilities or talents and command one to develop these and use them in specific ways. He can command one to become one type of person (say, a teacher) rather than another (say, a missionary). In these and many other ways, God can issue commands that guide one toward an individual calling, ultimately aimed at the end of becoming the person God intends one to become.Footnote 32 By obeying God's commands, both universal and individual, one achieves the human telos and – as both the Kierkegaardian pseudonym, Anti-Climacus, and Kierkegaard himself put it – one ‘becomes oneself’.Footnote 33
Evans considers the ethic he finds in Kierkegaard to be ‘a full-fledged divine command theory’ in which ‘all truly moral obligations owe their status as moral duties to the fact that God commands them’.Footnote 34 He is much more explicit than Quinn in describing how he thinks divine commands give rise to moral obligations. Following Robert M. Adams, Evans endorses a social theory of the nature of obligation.Footnote 35 According to this theory, social relations ‘carry with them obligations’, and ‘are in fact partly constituted by systems of obligation, even though these obligations may be “pre-moral” in character’.Footnote 36 Both Adams and Evans argue that our relation to God is properly described as a social relation that carries with it specific obligations; Evans claims further that it is an indispensable constituent of human flourishing.Footnote 37 However, a subset of the obligations generated by our relation to God is different from other socially-generated obligations in that they have the right characteristics to qualify them as moral obligations. Evans sums up his view as follows:
On this view we are creatures made by God for fellowship with God, and our deepest happiness depends on such a relation, one that requires love and gratitude to God on our part. The relation with God, like other social relations, generates obligations. In this case the obligations to obey God's commands are of a character to merit the description ‘moral.’ I believe that this is the right perspective from which to view Kierkegaard's ethics.Footnote 38
Evans cites three qualities that characterize moral obligations and distinguish them from other types of obligations.Footnote 39 First, they are objective: their binding power does not depend merely on the beliefs, practices, or customs of individuals, cultural groups, or societies. Second, they are ultimate: they give reasons for action that are overriding in relation to other, conflicting reasons, including those provided by other kinds of obligations. Finally, they are, in some cases at least, universal. Many divine commands are issued to all persons and thus impose moral obligations on everyone without exception. We can add to this that moral obligations are universal in another sense, as well: in any case in which one is obligated, anyone in relevantly similar circumstances would be similarly obligated. On a divine-command theory such as Evans's, however, this does not imply that moral properties must supervene on natural properties, where ‘natural properties’ are taken to refer (roughly) to those properties a naturalist metaphysic would allow. God can issue two individuals in similar ‘natural’ circumstances contrary commands, in which case they would be differently obligated. However, this is not to deny that moral obligations are universal, because being commanded by God is, for the divine-command theorist, a morally salient feature of any circumstance. Anyone similarly commanded by God will be similarly obligated.Footnote 40 Thus, the divine-command theorist still can allow that everyone who is in all relevant ways similarly circumstanced will have the same obligations.Footnote 41
I have argued elsewhere that combining DCT with a social theory of obligation results in a view that faces a number of serious problems.Footnote 42 I will not repeat these objections here. At present, I wish only to address the interpretive issue of whether a divine-command ethic is to be found in Kierkegaard's writings. Although I find much of Evans's reading of Kierkegaard to be compelling, I will now argue that, like Quinn, the textual evidence to which Evans appeals to support the claim that the Kierkegaardian ethic in Works of Love is a divine-command theory in fact supports only the view that Kierkegaard endorses the sufficiency clause, not DCT as a whole. More specifically, I will try to demonstrate that the argument Evans gives to show that Kierkegaard endorses DCT is invalid, and the prospects for reconstructing the argument to make it sound are not promising.
Several passages of Kierkegaard's Ethic of Love suggest that Evans believes it is obvious and even incontrovertible that Kierkegaard holds a version of DCT. He seems incredulous that M. Jamie Ferreira ‘actually goes so far as to deny that [Works of Love] contains a divine command account of moral obligation at all’,Footnote 43 and he later states explicitly, ‘When measured by my test, it seems undeniable to me that Kierkegaard does hold a divine command theory of obligation.’Footnote 44 The ‘test’ to which Evans refers here is simply the minimal version of DCT discussed in the first section of this chapter: namely, that divine commands are both necessary and sufficient for moral obligations and that moral obligations depend on divine commands (and not vice versa).
What is the support for the claim that Kierkegaard undeniably holds such a view? Evans is more deliberate than Quinn in arguing that Kierkegaard endorses both the sufficiency clause and the necessity clause, so his answer comes in two parts. The first part of his answer, in which he argues that Kierkegaard endorses the sufficiency clause, sounds much like Quinn:
For Kierkegaard, love for the neighbour is commanded, and its status as a serious moral duty depends on its being commanded. Furthermore, Kierkegaard believes that the concept of a command logically presupposes a commander with the authority to issue the command. God is the one who has this authority, and Kierkegaard does not flinch from the consequence of a divine command account of moral obligation that many people consider most offensive, which is that it implies that whatever God commands is obligatory.Footnote 45
Immediately following this, Evans quotes the following passage from Works of Love to support his claim:
But you shall love God in unconditional obedience, even if what he requires of you might seem to you to be your own harm, indeed, harmful to his cause; for God's wisdom is beyond all comparison with yours, and God's governance has no obligation of responsibility in relation to your sagacity. All you have to do is obey in love.Footnote 46
The first part of Evans's argument, then, is that Kierkegaard endorses the sufficiency clause.Footnote 47 Although I think that additional textual evidence from Kierkegaard's writings is needed to establish this conclusion,Footnote 48 I believe – for reasons I will not go into here – that Evans is right about Kierkegaard on this point. At any rate, I will not challenge this part of Evans's view. The problems arise, I believe, with Evans's argument that Kierkegaard endorses the necessity clause – an argument that, as far as I can tell, is contained entirely in the following passage:
It is not hard, I think, to show that Kierkegaard also accepts the claim that all our moral obligations are divine commands as well, and that there are no other adequate grounds for moral obligation. Kierkegaard holds that our moral duties to our fellow humans are both grounded in the command God gives us to love our neighbours as ourselves and are fulfilled by obeying this command. All our moral duties are therefore commanded by God or derived from such a command.Footnote 49
The argument here appears to be composed of a single (albeit multi-part) premise, given in the second sentence, and a conclusion, stated in the third sentence. The premise claims that (all) our duties to the neighbour are grounded in the command to love the neighbour, so that, by loving the neighbour, we fulfil our (entire) obligation to the neighbour. If one obeys this divine command, then one loves the neighbour as oneself, and if one loves the neighbour as oneself, then one fulfils one's obligation to the neighbour. Evans's argument, then, put a bit more formally, seems to be the following:
(1) Kierkegaard holds that God commands us to love our neighbours as ourselves.
(2) Kierkegaard holds that if we obey God's command to love our neighbours as ourselves, we will thereby fulfil our entire obligation to our neighbours.
(3) Kierkegaard holds that the entirety of our obligation to our neighbours is grounded in the command to love our neighbours as ourselves.
(4) Therefore, Kierkegaard endorses the necessity clause.
Premise (1) states an uncontroversial fact about Works of Love. Premise (2) states that, for Kierkegaard, obeying God's command to love the neighbour is sufficient for fulfilling one's obligation to the neighbour. The implication is that the command to love the neighbour entails all the moral obligations one has to the neighbour. Premise (3) claims that Kierkegaard endorses the asymmetrical dependency relation between the divine command to love the neighbour and the moral obligation(s) that this command brings about.
If I am right about this interpretation, then the argument can be restated more clearly and precisely as follows, where p is to be read as ‘God commands us to love our neighbours as ourselves’:
(1) Kierkegaard holds that p.
(2′) Kierkegaard holds that, for all q, if q expresses a moral obligation that one to the neighbour, then p entails that q.
(3′) Kierkegaard holds that, for all q, if q expresses a moral obligation that one to the neighbour, then q because p.
(4) Therefore, Kierkegaard endorses the necessity clause.
Again, roughly, (1) expresses a straightforward truth about Works of Love; (2′) claims that all of one's obligations to the neighbour are entailed by the so-called royal law,Footnote 50 and (3′) establishes the asymmetrical dependency relation between the royal law and the moral requirements in question.
The problem with this argument, however, is that it is invalid: (4) does not follow from (1), (2′), and (3′). There are at least two distinct reasons why this is the case. First, no combination of these premises is sufficient to establish the claim that no moral obligation to the neighbour could arise in any way other than God's commanding us – a crucial aspect of the necessity clause. As discussed in the first section, in order to make even a minimal version of DCT plausible, it must be strengthened to cover counterfactual claims about what we would be obligated to do in other possible worlds – for example, in worlds where God issues different commands. Each of the three parts of the minimal divine-command theory (the necessity clause, the sufficiency clause, and the asymmetrical relation clause) must be modified to account for this. Even if it is true that in the actual world, all one's obligations to the neighbour are fulfilled by one's obeying God's command to love the neighbour as oneself, this is not enough to establish the claim that in every possible world, obeying God's commands is sufficient for upholding one's entire duty to the neighbour. If there is some world in which obeying God's commands is insufficient for upholding one's entire duty to the neighbour, then, in this world, there is some binding moral obligation that is not grounded in a divine command. This entails that divine commands are not logically necessary for moral obligations in this possible world, which entails that the necessity clause is false in this possible world. This, in turn, entails that the necessity clause is false in every world (since the necessity clause claims to express a necessary truth), which entails that DCT is false in every world, including the actual world.
In fact, however, the argument is invalid even if it were plausible to strengthen its second and third premises as follows:
(1) Kierkegaard holds that p.
(2″) Kierkegaard holds that, necessarily, for all q, if q expresses a moral obligation that one has to the neighbour, then p entails that q.
(3″) Kierkegaard holds that, necessarily, for all q, if q expresses a moral obligation that one has to the neighbour, then q because p.
(4) Therefore, Kierkegaard endorses the necessity clause.
This argument avoids the first difficulty: it implies that no obligation to the neighbour is sufficiently grounded in a source other than a divine command in any possible world. But it faces additional problems. It would be much more difficult, of course, to provide textual evidence that establishes (2″) and (3″) than it would be to provide textual evidence for (2′) and (3′). But this is not the issue on which I will focus, because even if one could establish this, the argument still is invalid. The problem is that, according to (4), Kierkegaard endorses the claim that, necessarily, for all q, q expresses a moral obligation that one has (i.e. that is binding on one) only if God commands that q (or issues a command that entails that q). But what follows from (1), (2″), and (3″) is
(4′) Kierkegaard holds that, necessarily, for all q, q expresses a moral obligation that one has to the neighbour only if God issues a command that entails that q.
The problem is that (4′) does not entail that Kierkegaard endorses the necessity clause, because we have, prima facie at least, more moral obligations than we have just to our neighbours. Since there is nothing in (1), (2″) or (3″) that addresses these obligations, (4) does not follow from these premises.
Evans claims in the aforementioned passage that it follows from the fact that God has commanded us to love the neighbour that ‘all our moral duties are therefore either commanded by God or derived from such a command’.Footnote 51 In context, the command to which Evans refers here is the royal law; thus, the claim seems to be that all our moral duties are entailed by the royal law. If this were true, it would solve the problem by collapsing the distinction between (4) and (4′). But the claim seems implausible, given that we also have at least some moral obligations to God, and very likely also some moral obligations to non-human animals, some moral obligations to creation (e.g. to the environment), and/or some moral obligations to ourselves. It is hard to see how these obligations are entailed by the command to love the neighbour. At the very least, an argument is needed to establish this, and Evans offers no such argument.
In fact, if it were true that all of our moral duties followed from the duty to love the neighbour, this would be problematic for Evans, because he defends the notions of individual obligation and individual calling (vocation). As previously discussed, Evans claims that God issues (or at least could issue) some commands to particular individuals in order to bind them in some way that He does not bind others. However, he also claims that the duty to love the neighbour is promulgated via general revelation as well as special revelation, so it is binding on all persons.Footnote 52 But if the obligation to love the neighbour applies to all persons, and every moral obligation is entailed by the obligation to love the neighbour, then there are no moral obligations unique to particular individuals, and thus no actual examples of an individual calling. This reveals a dilemma for Evans: either the command to love the neighbour entails all our moral duties or it does not. If it does, then the possibility of an individual calling is precluded. If it does not, then (4′) does not entail that Kierkegaard endorses the necessity clause, in which case the divine command reading of Kierkegaard fails.
Furthermore, regardless of how the conclusion might be modified, another problem with this version of Evans's argument is that it follows from (1), (2″), and (3″) that Kierkegaard commits himself to the position that we have no moral obligations to the neighbour in any world in which God does not issue the royal law. Since (1) is only a claim about the actual world, it is consistent with the premises of the argument that there are such worlds. (And further, denying that there are any such worlds would amount to claiming that God issues the royal law necessarily – which implies that He does not issue it libertarian freely.) (3″) implies that moral obligations to the neighbour only arise in worlds in which it is true that God issues the royal law (‘… q [is true] because p [is true]’). This is implausible enough by itself, but it raises the following additional difficulty for the divine-command theorist: in some of the worlds in which God does not issue the royal law, He issues other commands (such as ‘Do not steal from your neighbour’), and yet, such commands do not impose moral obligations in these worlds because, according to (3″), the royal law provides the grounds for all the moral obligations to the neighbour that hold in a world. If the royal law is not issued in a world, then there is no grounding available for any moral obligations to the neighbour in that world; a fortiori, there are no binding moral obligations to the neighbour that are grounded in other divine commands. Obviously, this consequence is unacceptable for a divine-command theorist.Footnote 53
In short, trying to deduce DCT from the command to love the neighbour is dubious at best. Even if one plausibly can deduce the sufficiency clause from it,Footnote 54 one can deduce the necessity clause from the command to love the neighbour only by first establishing both that, necessarily, the command to love the neighbour is necessary for the obligation to love the neighbour and that, necessarily, the obligation to love the neighbour entails the whole of the moral law. Both of these claims are contentious: it remains an open question whether the obligation to love the neighbour must arise from a divine command, and it seems clear that the obligation to love the neighbour does not entail the whole of the moral law. In addition, in order to construct such an argument, one would need to add some premise that ensures that moral obligations to the neighbour can exist in worlds in which God does not issue the royal law; but it is hard to see what plausible premise(s) could be added that would accomplish this.
As far as I can tell, then, the only way to construct valid arguments that begin with claims for which there is strong textual evidence (e.g. that Kierkegaard thinks love for the neighbour is morally obligatory because it is commanded by God) and that end with the thesis Quinn and Evans defend (that Kierkegaard endorses a minimal divine-command theory) is by adding further, highly contentious premises.Footnote 55 The burden of proof is on Quinn and Evans either to provide arguments for these premises or to construct alternative arguments for their reading of Kierkegaard that do not employ such premises. In the absence of such arguments, I see no reason to accept the claim that Kierkegaard either endorses or commits himself to a minimal divine-command theory of moral obligation.
A final point is worth noting. Despite the passage discussed earlier, Evans indicates at one point in the conclusion of Kierkegaard's Ethic of Love that he thinks the command to love the neighbour extends only to interpersonal moral obligations, but that Kierkegaard's argument can be expanded to account for our other moral obligations. He claims that ‘it would be relatively easy to develop this [Kierkegaard's] account of moral obligations towards humans into a broader account that recognizes moral obligations to other animals and to the natural world generally’.Footnote 56 This view is more plausible than the view (which seems to be expressed earlier in the book) that all our moral obligations can be derived from the royal law. Nevertheless, adopting this view would not resolve the problems for the divine-command reading of Kierkegaard. First, even if we accept that our obligation to the neighbour is grounded in a divine command, there is no reason to assume that these other moral obligations likewise are grounded in divine commands. The two issues are at least logically independent, and if our moral obligations to the rest of creation are grounded in something other than divine commands, then the necessity clause is not met, and DCT is false. Second, the fact that Kierkegaard's account of moral obligation can be expanded into a divine-command theory does not provide evidence that Kierkegaard endorses a divine-command theory. In fact, it suggests the opposite: if a view has to be expanded in order to be made into a divine-command theory, then presumably it is not a divine-command theory prior to such modification. And finally, even if we can manage to account for our moral obligations to the rest of creation – including animals, the environment, and even ourselves (assuming we have such obligations) – this still does not account for our obligations to God. As I have discussed elsewhere, at least some of our moral obligations to God are such that grounding them in divine commands fails, so even if the ‘expansion’ strategy works for the rest of our moral obligations, it will not work for these.Footnote 57
Conclusion
Throughout this essay, the evidence presented against Quinn's and Evans's divine-command reading of Kierkegaard has been primarily ‘negative’ evidence: the emphasis has been on the lack of textual evidence in Kierkegaard's writings sufficient to establish that Kierkegaard endorses the necessity clause. Elsewhere, I have developed the case further with a presentation of ‘positive’ evidence: that is, textual evidence that Kierkegaard rejects the necessity clause, and, a fortiori, every meta-ethical divine-command theory of moral obligation.Footnote 58 In the present essay, I have alluded to such evidence in passing;Footnote 59 it consists in a number of interesting passages in which Kierkegaard suggests that the ultimate basis of moral obligation lies not in God's commands, but rather in the nature of creation and in God's relationship to it.Footnote 60 Since the necessity clause entails that there are no grounds that are possibly sufficient for moral obligations other than divine commands, this counts as positive evidence that Kierkegaard rejects the necessity clause. But a close examination and discussion of these passages must be saved for another time.Footnote 61
