Do genuine or real (rather than prima facie) moral dilemmas exist? Moral dilemmas are states of affairs in which an agent ought morally to adopt each of two alternatives but cannot adopt both simultaneously. The “ought” term corresponds to the relevant moral reason for adopting the alternative. This definition is provisional: because an answer to the essay title/question turns completely on the definition given, answer and definition must be provided together, i.e., in defining the dilemma we make the very case for its existence. Answering positively admits a deep incongruity within our ethical theories and, more importantly, our logic; answering negatively fails to acknowledge sufficiently our intuitions about an imperfect world. This essay acknowledges these sentiments and argues that the debate on moral dilemmas cannot be settled by appealing to the logic of deontic concepts, but rather to the nature of morality.1 In this order, I will first give two paradigmatic examples of moral dilemmas in which to frame the rest of the essay; second, I will define and argue the terms for irreducible moral dilemmas, rejecting rationalist arguments; afterwards, I will propound a positive argument explaining why these dilemmas are genuine, combining the literature on a plurality of conflicting values with the literature on moral residue; along the way I will answer any strong objections to my claims. I will then conclude. Ancient Greek poems and tragedies give us numerous examples of putative moral dilemmas. Whilst attempting to take back the abducted Helen, the woman whose face “launched a thousand ships,” Agamemnon and his huge fleet of Greek troops set for Troy were becalmed by the god Artemis. A prophet declared that no wind would arise, that the fleet couldn’t sail, unless Agamemnon sacrificed his daughter, Iphigenia, to Artemis. Agamemnon ought to both lead his troops against Troy, and ought not to kill his daughter. It is a dilemma because adopting one alternative means excluding the other. Defining the dilemma, it’s possible for the “ought” to be reformulated, in explaining certain dilemmas, as “ought not.”2 In Styron’s Sophie’s Choice we find another example of a moral dilemma. Here the agent, Sophie, has to choose, upon entering Auschwitz, which one of her two children will live, 1 2 Peter Vallentyne, “Two Types of Moral Dilemmas”, Erkenntnis (1989), Vol (30), 317 Walter Sinnott-Armstrong, Moral Dilemmas, (Oxford: Blackwell, 1988), 5 1 and which one will die. The drunken, Nazi doctor who presents Sophie this choice also tells her that if she does not choose both children will die. We have a dilemma because Sophie ought to protect both of her children but is forced to choose one whom will be killed. Defining the dilemma, it could be said that Sophie’s dilemma arose due to contingent features of the world i.e., the Nazi occupation.3 The standard way to resist these putative dilemmas is to let your ethical theory reduce the apparency of conflict to the reality of a lack of conflict. Deontologists and consequentialists both posit an ability to reduce the apparent dilemma to simple moral conflict or even a lack of conflict whatsoever. For example, Kant thought that moral dilemmas were inconceivable; if something is a moral necessity, to do A, then it cannot also be a duty to do something incompatible with A.4 Depending on what your absolute morality entails, you would simply make the choice of one of the two alternatives; there are no conflicting obligations, only conflicting grounds for obligation.5 Kant’s preferred alternative would be the one with stronger grounds for obligation.6 A utilitarian theory would weigh the two alternatives in order of the respective amounts of happiness/good/utility/preference-satisfaction they would create, and then choose the alternative which maximises this good. To paraphrase Mill, unequivocal cases of conflicting obligation do arise, but, if utility is the ultimate source of moral obligations, utility may be invoked to decide between them when their demands are incompatible.7 Agamemnon, if he subscribed to a deontology which ranks his martial duties above his familial duties, then, is free to sacrifice his daughter; likewise, if he acted to maximise utility, he might have chosen to spare his daughter, under the idea that overall utility would be greater this way. Crucially, Agamemnon commits no wrong, but this idea conflicts with our intuitions about his situation; the opposition between our intuitions and rationalist theories is where the theoretical debate gestates. 3 Christopher W. Gowans, Moral Dilemmas, (Oxford: OUP, 1987), 3 4 Immanuel Kant, “Moral Duties” in Gowans, Moral Dilemmas, (Oxford: OUP, 1987), 6 Kant, 39 5 6 Kant, 40 7 John Stuart Mill, “Utilitarianism and Moral Conflicts” in Gowans, Moral Dilemmas, (Oxford: OUP, 1987), 54-5 2 I fully endorse the view that there are specific conditions of dilemmas which render the above ethical systems unable to reduce the dilemma to conflict; sometimes, moral requirements cannot be overridden. Sinnott-Armstong codified these as the conditions of symmetry and incomparability. For Sophie, there is no morally relevant difference between her two children; she is obligated (because they will both die if she does not choose) to adopt from two identical options; her choice is morally symmetrical. Answering the epistemological/ontological distinction and objection, the point isn’t just that Sophie doesn’t know which alternative is stronger, it’s that there is in fact no morally relevant difference between the alternatives.8 Our theories of morality, as stated above, do not seem to have a sufficient system for ranking this dilemma’s alternatives. The common response to this argument is to argue that the requirement is simply disjunctive. For Sophie, she should act to save either one of her children, for that is the best she can do.9 I do not believe this response sufficiently addresses the real concern with moral dilemmas. First, there are non-disjunctive moral requirements not to choose each child. Sophie would still be cooperating in one child’s murder, and crucially, Sophie’s choice still makes a difference. She is not choosing between notes in her wallet, she is acting on non-interchangeable alternatives. These non-disjunctive requirements are not overridden by the disjunctive requirement.10 The moral duty, stemming from her parental role, equally applied to both children, does not disappear with the necessity of the situation; Sophie is a parent always. To take Gowans’ line, in acting for the best we still choose an evil, and in this sense do something wrong.11 Second, there will always be possible choice situations in which no action is permissible. Consider Vallentyne’s sexist-club rules: firstly, a rule prohibiting men from sitting when a woman is in the club; secondly, a rule prohibiting men from being in any position other than a 8 Walter Sinnott-Armstrong, “Moral Dilemmas and Incomparability”, in American Philosophical Quarterly (1985), Vol (22): 321-9 9 McConnell, Terrance, "Moral Dilemmas", The Stanford Encyclopedia of Philosophy (Summer 2010 Edition), Edward N. Zalta (ed.), URL = <http://plato.stanford.edu/archives/sum2010/entries/moral-dilemmas/> 10 Sinnott-Armstrong, “Moral Dilemmas and Incomparability”, in American Philosophical Quarterly (1985), Vol (22): 326 11 Christopher W. Gowans, Innocence Lost, (Oxford: OUP, 1994), 3 3 sitting position when a woman is in the club. Suppose the first rule is replaced by the second but not repealed and member’s habits are forgotten. Then, in the club, whenever a man is in the presence of a woman, he is prohibited from every positional action. The point is that these rules do not issue contradictory directives. They merely prohibit everything in that choice situation. 12 I agree with Vallentyne that token prohibition dilemmas, and quasi-obligation dilemmas, are conceptually possible then, for at least some normative situations, like the club above. Sophie’s choice is another prime example. Sinnott-Armstrong’s second feature was that of incomparability. Giving the example of the incomparability of death and pain, he argued that it’s implausible to insist that death must equal an exact amount of pain, and that this inexactness “can explain how a moral requirement of one kind can be comparable with some but not all moral requirements.” Intuitively, incomparability features (non-morally) in our everyday lives; for Agamemnon, the utterly incomparable duty to his daughter and the duty to sack Troy, meant moral dilemma. I agree with Sinnott-Armstrong’s conclusion that limited incomparability among moral requirements is a possibility and therefore that moral dilemmas are possible. Sophie and Agamemnon experience moral conflicts displaying these properties; they experience a lack of an overriding moral requirement. And because there is a lack of an overriding moral requirement, the putative moral dilemma cannot be reduced to a resolvable moral conflict. And so I choose to strengthen the definition of a genuine or real moral dilemma to an irresolvable situation where moral requirements of alternatives conflict, neither is overridden in any morally relevant way, and the agent cannot adopt both alternatives together but only each separately.13 A combination of counterfactual reasoning, in which subjunctive conditionals illustrate mutually exclusive alternatives, and the lack of an overriding moral requirement seems to posit the existence of moral dilemmas as defined above. Some strong rationalists however, Kantians and latter-day rationalists, have rejected the very admittance of counterfactuals, specifically from fiction, in resolving the ontological question at hand. 14 Mothersill likened the giving of fictional 12 Vallentyne, 7 13 Sinnott-Armstrong, Moral Dilemmas, 23 14 Mothersill, 69 4 examples to G.E. Moore’s proof of an external world.15 I disagree; the widespread, legitimate use of counterfactual conditionals in analytic philosophy, and Sinnot-Armstrong’s conditions, entails moral dilemmas which are not simply conceivable, but moral dilemmas as facts of life to be reckoned and wrestled with. The issue is whether there are or can be genuine dilemmas.16 The theorists which do indeed answer the challenge of our fictional counterfactuals, do so only to refuse to acknowledge these cases as moral dilemmas. These rationalists17 instead claim that agents like Agamemnon and Sophie are simply caught in an apparent or prima facie dilemma, and that, once various confusions have been resolved, the dilemma ceases to be a dilemma. The main reason rationalists preclude moral dilemmas, as defined above, is that not doing so means accepting inconsistencies in our logic, namely “truisms…and paradoxes”.21 These illogicisms are the consequence of a combination of two things: the proposition that dilemmas exist; and the axioms of deontic consistency (If obligated to do A, then not obligated to not do A) and deontic logic (Necessarily, if A then B, then, if obligated to do A, then obligated to do B).22 Unsurprisingly, there are problems with this logic still under construction.23 And I believe there is a fundamental disanology between the deontic modalities of obligation, prohibition, and permission, and the alethic modalities of necessity, impossibility, and possibility.24 Necessity does not seem to be synonymous with obligation. There are many things besides this essay I ought to be doing, but it does not necessarily follow that I ought to be doing all those things and this essay; agglomeration does not seem to hold. Likewise, the “ought implies can” principle has been questioned in its contextual use: interpretations such as “ought to do”, “ought to be”, “ought 15 Mothersill, 74 Sinnot-Armstrong, 29 17 Mary Mothersill, “The Moral Dilemmas Debate” in Mason, Moral Dilemmas and Moral Theory, (Oxford: OUP, 1996), 66 16 21 McConnell, Terrance, "Moral Dilemmas", The Stanford Encyclopedia of Philosophy (Summer 2010 Edition), Edward N. Zalta (ed.), URL = <http://plato.stanford.edu/archives/sum2010/entries/moral-dilemmas/> 22 McConnell, Terrance, “Dilemmas and Consistency”, The Stanford Encyclopedia of Philosophy (Summer 2010 Edition), Edward N.

Because of the aforementioned problems, and the monist assumptions deontic logic makes, I am not positing dialetheism but agreeing with Williams that it’s the world, not logic, which makes it impossible for both alternatives to be satisfied. The following argument recognises this and argues that the nature of morality is that of a plurality of values, a heterogeneity of moral worth, and that there is a contingent basis on which these heterogenous values clash. I believe that value pluralism is the only view which satisfies our intuitions about the moral reality and explains the continual complexities, conflicts, and dilemmas it affords us. The various values which we commonsensically talk about, such as happiness, freedom, friendship, are genuinely irreducible to the super values of monist theories.28 This view was made explicit by Nagel when he rejected that the source of value was unitary and that this only displays multiplicity. There exists a nigh infinite list of obligations, rights, utility, perfectionist ends, and private commitments which inevitably come into conflict with one another. Nagel gives the example of perfectionist and utilitarian values which, being formally different, are concerned with levels of achievement and not spread of achievement.29 Berlin talked of “collisions of value...of the essence of what they are and what we are...the world in which these values are compatible, is a world beyond our ken...but it is on earth that we live, and it is here that we must believe and act.30 25 Mothersill, 70 Vallentyne, 16 27 Gowans, “The Debate in Moral Dilemmas”, in Moral Dilemmas, (Oxford: OUP, 1987) 26 28 Elinor Mason, "Value Pluralism", The Stanford Encyclopedia of Philosophy (Fall 2011 Edition), Edward N. Zalta (ed.), URL = <http://plato.stanford.edu/archives/fall2011/entries/value-pluralism/> 29 Thomas Nagel, “The Fragmentation of Value” in Gowans, Moral Dilemmas, (Oxford: OUP, 1987), 178 6 Both authors complement well the following view. That it should be recognised within moral theory that human beings reflect on their own distinguishing desires and interests, and on their own actions, in their own distinct languages, behaviours, histories, rationalities.31 The clash of values: freedom against equality; Agamemnon’s martial versus his familial duties; from the existential challenges of Huntington's civilisations to those everyday, common of promises made in spite of an imperfect world. As Hampshire put it, “a direct consequence of the capacity to recognise and to name differences, a whole range of different complete lives is represented as normal for human beings...the capacity to envisage conflicts between norms for a complete life, conflicts of ends and values, is natural in human beings.”32 In conjunction with the problems in deontic logic, it seems entirely plausible “that there are generically different ways in which it can come true that we ought to do something or ought not to do something;” Lemmon refers us to the reasons of varying status or position, previous commitments, and moral principles.33 In addition, we have many different perspectives from which to view these values. When I make an ethical judgement on Abraham, intending to murder his son, ignorant of future divine-intervention, am I judging him by relating to him (or Isaac, or even God?), by extending my life through time, from every one's point of view, or from a detached sub specie aeternitatis viewpoint?34 These complexities in human thought seem to preclude any reductionist or monist theory. Indeed, what exactly is the moral in Abraham’s case?35 Monist objections, often originating from the deontic and utilitarian traditions, will continuepropounding that there is one moral super-value to which all others can be reduced to, and to which no non-moral values can conflict with --often, a distinction is made between moral and non-moral values. However, where a monist would see clear lines for distinguishing between 30 Isaiah Berlin, “The Pursuit of the Ideal”, in The Proper Study of Mankind: An Anthology of Essays, (Farrar, Strauss and Giroux, 2000) 31 32 Stuart Hampshire, Morality and Conflict, (Cambridge: Harvard, 1984), 145 Hampshire, 145 33 E. J. Lemmon, “Moral Dilemmas” in Gowans, Moral Dilemmas, (Oxford: OUP, 1987) 105 34 Nagel, 180 35 Martin Cohen, 101 Ethical Dilemmas, (London: Routledge, 2003), 61 7 moral and non-moral values, I can only see the drawing of an arbitrary line. Considering ethics pervades every aspect of life, just where exactly should the line be drawn? Furthermore, a distinction wouldn’t completely rule out conflicts, one of the reasons for drawing it in the first place. Marcus argues that there can still be conflicts with one moral principle; the example he gives is of promise-keeping two independent promises where unforeseeable circumstances have made it impossible to keep both.36 Likewise, Sophie’s choice is immune to any distinction a monist would make. My second argument posits that there are phenomenological features experienced by the agent, like deep regret, remorse, and guilt which evidence the dilemmatic proposition that the agent is obligated to do wrong. Immediate objection is proffered that I am begging the question as to just why “moral residue” is appropriate.37 However, I believe, like Sinnot-Armstrong, that this objection misses the point of inference; moral residue is the best explanation of the different intuitions about different emotions appropriate in different situations. Gowans’ notion was that the “inescapable distress” is caused by the agent balancing, and having to forgo, some moral responsibilities between persons.38 In Woody Allen’s Crimes and Misdemeanours, the guilt Judah felt after making his murderous decision, was, in itself, a punishment for the act of forsaking responsibilities to his mistress. Allen returned to this subject again and again,39 drawing inspiration from Dostoyevsky’s Raskolnikov, and all four Karamazov brothers, who are racked with regret and guilt far beyond the simple “pangs of conscience” because of their roles in respective murders and patricide. In both cases, human relationships entailed moral responsibilities. It’s only contingent that Judah overcomes his guilt and lives with his crime, whilst Raskolnikov is tortured and harangued by his own conscience to a state of confession; the guilt, in itself, however, is necessary, despite some people being able to cope with it better than others. Indeed, an anthropological viewpoint would put these phenomena as necessary to our moral reality. Theories which preclude dilemmas are also theories which do not pay attention to these moral relationships of responsibility; deontologists and utilitarians both 36 Gowans, 19 37 Sinnott-Armstrong, 52 Gowans, Innocence Lost, 20 39 Jerold Abrams, “Unlimited Voyeurism and Aesthetic Self-Fashioning” in Conard and Skoble, Woody Allen and Philosophy: You Mean My Whole Fallacy is Wrong?,(Illinois: Open Court, 2004), 113-7 38 8 agree that ultimate responsibility is to some “abstraction...whole sentient creation...the moral law.” I believe these theories “improperly displace persons as direct objects of moral concern.”40 We are estranged from our true nature as morally related, responsible agents. Alternatively, Williams viewed conflicts of morality as more like conflicts of desires than conflicts of belief.41 When we yearn for sexual intimacy and our advances are spurned, “the rejected desire is not abandoned.” Crucially, the opportunity for satisfying the desire having irrevocably gone, it may reappear in the form of regret for what was missed.42 Therefore, whether they work like desires or failures of responsibility to persons, Conee’s objection that moral residues are simply facts of “rational moral psychology”43 is seemingly erroneous. Indeed, experimental philosophy has confirmed that our ethical experience is of an irreducible plurality of values.44 The strong objection would be to point out that although regret is a fact of life, it comes about in all manner of situations, non-moral, and moral, and therefore that it would be useless attempting to distinguish dilemmas with such a widespread phenomenon. This objection is intuitive, we all make decisions we regret. There are numerous explanations of regret and residue that are explained non-morally: regret, for the situation, for the consequences, for an ultimately arbitrary moral code one has subscribed to which has made possible the conflict. Finally, it is alleged that nothing rules out this “moral remainder” being only prima facie, from a duty-like appearance, in Ross,45 or the way humans are educated to follow principles, in Hare.46 In short, the problem seems to be that although regret seems to be important, the mere fact that there is regret, does not prove something is regrettable.47 Despite this, when considered in combination with the prior argument, the existence of regret as moral remainder proves that a plurality of values is operating. Because of cases in 40 Gowans, Innocence Lost, 21 41 Bernard Williams, “Ethical Consistency” in Gowans, Moral Dilemmas, (Oxford: OUP, 1987), 115-37 42 Williams, 119 43 Earl Conee, “Against Moral Dilemmas” in Gowans, Moral Dilemmas, (Oxford: OUP, 1987), 239-49 44 Elinor Mason, "The attraction of pluralism", The Stanford Encyclopedia of Philosophy (Fall 2011 Edition), Edward N.

Monism cannot accommodate this. Pluralism explains the phenomenological remainder; we can regret not having chosen something which, though less “good,” was different.49 There is indeed a pluralism of values operating on agents. Indeed, as Nussbaum pointed out, a lack of this remainder seems strange and incompatible with the “the insights of tragedy.”50 The best an agent can do is to have his suffering, the natural expression of his goodness of character, and not to stifle these responses out of misguided optimism. The moral reality requires an appropriate character of agent when dealing with dilemma. Whilst “a good person will see it as what it is,”51 Agamemnon thought the situation, once a decision had been made, was “soluble,” the competing claim counted as nothing.52 When Agamemnon retreats from “moral conflict to moral indifference,”53 he cannot at the same time admit that he was in a genuine conflict of moral claims. To admit that there exist moral claims in situations of that sort is incompatible with holding moral indifference towards those situations.54 Inherent in the definition of a moral claim is that it cannot be ignored, even inaction is morally charged. Gowans claimed the debate is dominated by two opposed philosophical styles: rationalist and experientialist, mirroring the opposition and the proposition for dilemmas.55 If this is the choice, then I side with the experientialists. In my mind, morality is always concerned with how we treat our fellow human beings as “intrinsically and irreplaceably valuable”;56 agent-centered 48 Elinor Mason, "Value Pluralism", The Stanford Encyclopedia of Philosophy (Fall 2011 Edition), Edward N.

When the contingent features of the world inevitably bring about the opposition of a multitude of values, rationality and pathos, duties to his army, to his honour, to his ego, his responsibilities to his daughter, to his family, to his family history, Agamemnon acknowledges his conflict of values. But, as I have proved, and as the Greek chorus sings, Agamemnon, unlike Sophie, fails to acknowledge his decisive wrong. The sacrifice of the “intrinsically and irreplaceably valuable” Iphigenia means Agamemnon is required, not to stab out his eyes, but to allow a persistence of the rejected alternative; to receive the dilemma and its aftermath with “constructive expression.”57 In summary, I have addressed the major concerns and put forth a strong positive argument, combining elements of the literature on moral residue and a pluralism of values. This argument makes a very good case for the possible existence of genuine moral dilemmas (as I have defined them). Agamemnon and Sophie are caught in moral dilemmas: Sophie cannot make a non-arbitrary decision, Agamemnon cannot compare his alternatives; both are subject to forces beyond their control; both experience the presence of conflicting value(s). Concluding, I agree with Stocker that it is to wrongly limit our understanding of ethics to concern ourselves exclusively with action-guiding evaluations; independent prominence must be given to agents and situations.58 Unlike Sophie, Agamemnon did not acknowledge his tragedy; virtues, character, and emotions are of prime importance to morality. If, however, solutions are the object, for the unfortunate agent, I offer Marcus’s consolation that “one ought to act in such a way that, if one ought to do x and ought to do y, then one can do both x and y.”59 For the optimistic theorist, however, I can only invoke Mothersill’s scepticism that no ethical theory promises a unique solution to every moral problem.60 57 Williams, 129 58 Michael Stocker, Plural and Conflicting Values, (Oxford: Clarendon Press, 1990), 93 Marcus, 16 59 60 Mothersill, 73 11 Bibliography Berlin, Isaiah, The Proper Study of Mankind: An Anthology of Essays, Farrar, Strauss and Giroux, 2000 Cohen, Martin, 101 Ethical Dilemmas, London: Routledge, 2003 Conard and Skoble, Woody Allen and Philosophy: You Mean My Whole Fallacy is Wrong?,Illinois: Open Court, 2004 Gowans, Christopher W., Moral Dilemmas, Oxford: OUP, 1987 Gowans, Christopher W., Innocence Lost, Oxford: OUP, 1994 12 Hampshire, Stuart, Morality and Conflict, Cambridge: Harvard, 1984 Honderich, Ted, The Oxford Companion to Philosophy, Oxford: OUP, 1995 Mason, H.E., Moral Dilemmas and Moral Theory, Oxford: OUP, 1996 Mason, Elinor, "Value Pluralism", The Stanford Encyclopedia of Philosophy (Fall 2011 Edition), Edward N.
