The correlation with psychological problems argument

•   P1: That which leads to psychological problems is harmful.

•   P2: Prostitution leads to psychological problems.

•     C: Prostitution is harmful.

This is a common argument with strong intuitive appeal. P1 seems undeniable. P2 is an empirical claim, and to assess it, it seems that we should consult psychological research on prostitution. When we do, we find that a significant number of prostitutes suffer from panic attacks, eating disorders, depression and insomnia, that many experience guilt, regret and remorse after having sold sex, and the suicide rate among prostitutes is six times that of the average population.ⁱⁱⁱ Since it is very implausible that such correlations are accidental, P1 and P2 both seem to be true. Thus we seem to have good reason to believe that prostitution is harmful (C)—even if we accept the weak significance view of sex.

The problem with this argument is that accepting that prostitutes often experience psychological problems, and that this correlation is not accidental, does not imply accepting that prostitution leads to psychological problems.

To make this point clear, we may turn to the literature on, and the debate over, homosexuality in the 1920s and 1930s. What we find in this literature is that homosexuals in the early 20th century also experienced guilt, regret and remorse, were significantly more prone to depression, eating disorders and insomnia than non-homosexuals, and had a significantly higher suicide rate than the rest of the population.7 ,8

These figures were used by opponents of homosexuality as allegedly scientific evidence that homosexuality is harmful. Today, however, most of us would claim that they misinterpreted the data. Though we would concede that many homosexuals did suffer from these problems, we would argue that the statistics themselves were insufficient to establish that there was anything inherently harmful in being a homosexual or in engaging in homosexual practice, and that the correlation was most likely due to the social treatment of homosexuals at the time. After all, homosexuals were subject to significant social stigma.

As long as we are merely spotting a correlation, therefore, we cannot exclude the possibility that to a larger or smaller extent, the same is true of prostitutes. Prostitutes, after all, are also subject to social stigma. ‘Whore’ and ‘hooker’ are highly derogatory terms, and Yolanda Estes, a former prostitute who is now a philosophy professor at Mississippi State University, claims in ‘Prostitution: a subjective position’ that if she had been open about her background all along, this would seriously have damaged her career.9 Indeed, as notes prostitution researcher Teela Sanders, we have a strong historical tradition for portraying sex workers as ‘purveyors of disease, a social evil (and) a public nuisance …’.10

I am not here making the strong claim that homosexuality in the early 20th century and prostitution today are perfect parallels. For all I argue (so far), it might well be that while there is nothing inherently harmful in homosexuality, there is something inherently harmful in prostitution. As such, there might be excellent reasons why prostitutes, even apart from the social stigma, naturally experience psychological problems. The stigma might even be proper. What I argue is merely that statistical correlation between prostitution and various psychological problems is not alone sufficient to conclude that prostitution leads to these problems. Since an argument from mere correlation with psychological problems alone fails to establish C, we will need additional arguments to show that prostitution is harmful.

The correlation with danger argument

•   P1: That which is dangerous is harmful.

•   P2: Prostitution is dangerous.

•     C: Prostitution is harmful.

This is an argument formally similar to Argument 1, and it seems equally forceful. P1 seems obvious, at least if the danger in question is excessive. P2, here as above, is an empirical claim, and consulting sociological and criminological research, we find that prostitution intimately correlates with venereal disease, criminal underground networks, drug abuse and violence.4 In a 1998 study, Melissa Farley and Howard Barkan found that 82% of the prostitutes whom they interviewed had been physically assaulted.6 In 2008, Ulla Bjørndal and Bjørg Norli found that 72% had been victims of acts such as slapping, punching, kicking, robbing, burning, biting, raping and choking.11 Being subject to violence of this kind clearly seems dangerous (P2), and as such, it seems that prostitution is harmful (C).

Here again, however, we can use the history of homosexuality to show that the argument, as it stands, need not tell us much about the nature of prostitution. The reason why is that homosexual practice, when forbidden and condemned, also correlated strongly with venereal disease, underground networks, drug abuse and various forms of violence, and just as in the case above, these figures were used by opponents of homosexuality as allegedly scientific arguments supporting the view that homosexuality is harmful.12 Today, however, most of us would claim, again, that the data were misinterpreted. Though we would concede that many homosexuals did suffer from these problems, we would argue that the statistics were insufficient to establish that there was anything harmful inherent in being a homosexual or in engaging in homosexual practice. Rather, we would argue that the correlation most likely was due to the social and legal treatment of homosexuals at the time. After all, homosexuals were socially and legally oppressed.

Unless we wish to embrace a methodology that would have made us conclude, 70 years back in time, that homosexuality is harmful, we cannot conclude from these correlations alone that prostitution is harmful, for the social and legal treatment could be the source of these correlations as well. Indeed, it seems that this can be plausibly argued. In addition to the social stigma, the law (speaking here of current legislation in my own country, Norway) prevents prostitutes from joining labour unions, organising their work in brothels, renting a place where they can work, hiring security agencies, advertising and forming work contracts (regarding salary, working hours, working conditions, health insurance, retirement savings, and so on). It does not seem obviously wrong to hold that such legal restrictions contribute to pushing prostitutes away from civil society and make their lives rougher (this point is well argued by Almodovar13).

Again, there might be excellent reasons why a correlation with harmful activities would be likely to occur across a wide spectrum of legal treatments, or indeed, why a strict legal treatment is proper. To make the case for this, however, no argument from mere correlation will suffice. In order to convincingly argue that engaging in prostitution is harmful, one will need to point to something either intrinsic to the activity of buying and selling sex, or to a natural consequence thereof, that is harmful. The rest of this paper is concerned with arguments that seek to establish this.

The objectification argument

•   P1: That which involves objectification is harmful.

•   P2: Prostitution involves objectification.

•     C: Prostitution is harmful.

This argument purports to say something about the very nature of prostitution, and as with Arguments 1 and 2 above, it seems intuitively plausible. It seems harmful to use people as objects (P1) and this seems to be what goes on when a client uses a prostitute to satisfy his sexual desires (P2). Thus it seems that prostitution is harmful (C).

Before we can assess this argument we must—to avoid equivocation—get a clear understanding of what we mean by ‘objectification’. Let's examine two different senses of the term ‘objectification’ that are in use in the prostitution debate, one narrow and one wide.

In a narrow sense, such as Thomas Mappes’ in ‘Sexual morality and the concept of using another person’, objectification means dealing with other persons by means of force or fraud, that is, to the practice of using others as objects that one may manipulate and dispose of as one pleases. In a broader sense, such as Howard Klepper's in ‘Sexual exploitation and the value of persons’, objectification is not restricted to force and fraud, but includes any treatment of another person as a means to one's ends without regard for that person's own ends.^iv

On Mappes’ narrow account of objectification, P1 seems true. On this account it is doubtful if P2 is true, that is, if prostitution involves objectification. However, though prostitution might in some or in many cases involve force or fraud, or both, it is not clear how this constitutes an argument against the very activity of buying and selling sex. It seems that using force or fraud is always (or nearly always) harmful, and the fact that it is harmful to force or defraud someone to φ is not a sufficient reason to conclude that it is harmful to φ. The fact that it is harmful to force someone to marry, for example, does not show that marrying is harmful. Indeed, one could argue that in cases where force or fraud is used, we should not even speak of prostitution, but of rape or sexual slavery. If prostitution means buying and selling sex—and ‘buying’ and ‘selling’, to be applicable concepts, presuppose at least a thin notion of voluntariness—it seems just as unreasonable to label sex slavery ‘prostitution’ as to label someone who is filmed while raped a ‘porn actress’. Thus Mappes’ narrow account of objectification, though we should concede that it identifies a harmful form of objectification, does not render P2 true and thus does not establish that prostitution is harmful.

On Klepper's broader account, we face not just one problem, but two. The first problem is that on this account, P1 is doubtful, since many actions that we perform on a daily basis also qualify as objectification. I, for one, use my newspaper delivery man as an object in Klepper's sense of the term. Though I hope my newspaper delivery man is doing well, I cannot say that I do much to help him reach his goals. I use him as an object—a newspaper delivery object—and as a consequence, he is fungible to me. Since I am still in bed when he delivers my newspaper, I would not notice it if he were replaced by another, equally punctual, newspaper delivery man (or, indeed, by a newspaper delivery machine). Thus it seems that I use him as an object on Klepper's account. Unless we should grant that we harm our newspaper delivery men, shoemakers, baristas and lawyers by doing ordinary business with them, it seems that we cannot rationally regard all sorts of Klepperian objectification as harmful—at least not in any significant way.

Even if we (generously) grant that P1 is true on Klepper's account objectification, it is not clear, however, how prostitution qualifies as such objectification—or, at least, how prostitution qualifies as objectification to a larger extent than activities that undeniably appear harmless. As Irving Singer has pointed out, ‘there is nothing in the nature of sexuality as such that necessarily … reduces persons to things’, and the reason for this, Singer explains, is that there is something fundamentally reciprocal to sex.17 Bordering to this, Thomas Nagel points out in ‘Sexual perversion’ that a crucial aspect of sex is that we tend to derive pleasure from our sexual partner's pleasure.18 If Singer and Nagel are right, it seems that since a prostitute sells sex, it is not unlikely that at least to some extent, it matters to the client how she feels. Prejudice aside, it could be argued that prostitution is one of few trades where it is natural that the buyer to some extent cares for the seller. Perhaps for this very reason, it seems that prostitutes are less fungible than sellers of most other services. It seems that a buyer of sex would care more about what prostitute he has sex with than I care who delivers my newspaper, and it also seems that a client would be more likely to build a personal relationship with his long-term prostitute than I would with my long-term newspaper delivery man. Of course, there could be (and sadly, are) extremely objectifying clients who do not care the least about those whom they pay for sex. Even if we grant that such carelessness is harmful, however, this is not an argument against prostitution as such, since it fails to show that there is something inherent in the activity of buying and selling sexual services that leads to objectification or makes objectification likely.

Thus P2 is doubtful on Mappes’ account, and P1 and P2 are doubtful on Klepper's account. Unless we can find an objectification argument that appeals to a harmful form of objectification and, at the same time, applies to prostitution, we need separate arguments to show that prostitution is harmful.

The exploitation argument

•   P1: That which involves exploitation is harmful.

•   P2: Prostitution involves exploitation.

•     C: Prostitution is harmful.

While objectification is the practice of using other persons as objects, exploitation is the practice of profiting unduly from others’ work. If agent A works productively all day, yet earns almost nothing, while agent B earns what is rightfully A's, then B exploits A. This seems to harm A. If this is right, and prostitution involves such exploitation (P2), then prostitution is harmful (C).

For the sake of the argument, I will grant that P1 is true. It is unclear, however, if P2 is true—or, at least, if buying and selling sex involves or leads to more exploitation than buying and selling other goods and services. Even in today's context—a context with discriminating laws and social stigma—prostitutes do not seem to be significantly more exploited than others. For one, there are luxury prostitutes who earn significantly more than society's average income. Though these, of course, are exceptions, the income for ordinary prostitutes also appears to be fairly good, at least when compared to other kinds of low-skill, labour-intensive, and female-dominated work, which is the realistic alternative for most people engaged in prostitution. According to labour economists Lena Edlund and Evelyn Korn, prostitutes have an average yearly income between two and six times that of other women in this group.19 Similar findings have been replicated in other studies. Roger Matthews, in a survey conducted in London in 1996, found that prostitutes earned almost three times that of other manual workers.20 In a more recent survey conducted in Chicago, Steven Levitt and Sudhir Alladi Venkatesh found that street prostitutes on average make $25–$30 per hour.^v That is perhaps not a huge salary, but it is four times the minimum wage.^vi Neither is it clear that pimps exploit prostitutes to the extent that we often assume. According to Edlund and Korn, the spot-like nature of prostitution renders it hard for pimps to profit, and in a 1995 survey, Lee Lillard found that less than 6% of Los Angeles’ prostitutes share income with a pimp. Shyamala Nagaraj and Siti Rohani Yahaya, studying non-Western prostitution, found that in Malaysia, prostitutes on average share 2% of their income with pimps (see figures in Edlund and Korn19).

Clearly, there is still profit involved in organising prostitution. That, however, fails to single out prostitution as a harmful profession, since profit is involved in organising virtually all professions. It seems, moreover, that a brothel—at least when run in a civilised manner—has the potential to contribute to the profit of a prostitute much the same way a hairdressing salon might contribute to the profit of a hairdresser, by providing facilities, steady income, safety, advertising, etc. This is supported by the findings of Levitt and Venkatesh, according to which prostitutes working under pimps on average earn more per week than prostitutes working alone—even though they work fewer hours and perform fewer tricks.21 For these reasons, we cannot take for granted without further argument that all profiting from prostitution has an exploitive nature.

Neither can we take for granted that when extremely poor women (or men) sell sex, and are harmfully exploited when doing so, it is the selling of sex—and not the poverty—that is the genuine source of the harm. Within the context of extreme poverty, exploitation can take place in most professions. This does not establish that these professions are harmful. The fact that construction work performed 15 h a day without safety equipment is harmful, does not establish that construction work is harmful. Similarly, the fact that selling sex 15 h a day without safety equipment is harmful, does not establish that selling sex is harmful. It only establishes that selling sex can be practiced in a harmful manner, which is uncontroversial.

The male dominance argument

•   P1: That which involves male dominance is harmful.

•   P2: Prostitution involves male dominance.

•     C: Prostitution is harmful.

This feminist critique of prostitution also seems forceful. Male dominance seems unjust and harmful (P1) and when women earn a living by satisfying men's sexual desires, what goes on looks like male dominance (P2). Thus it seems that prostitution is harmful (C).

Though I believe we should grant P1, it is not clear that P2 is true.

A first problem with P2 is the fact that prostitution is manifold, and that there are male and female prostitutes serving male and female clients. Even if we focus exclusively on stereotypical prostitution involving female prostitutes and male clients, however, it is not clear that male dominance is involved. Though there are many ways to account for the feminist charge of male dominance, I will here consider an influential argument put forth by Carole Pateman in ‘Defending prostitution: charges against Ericsson’.^vii Pateman argues that ‘prostitution remains morally undesirable, no matter what reforms are made, because it is one of the most graphic examples of men's domination over women’. She supports this by arguing that a market demand for sexual services is the result of a ‘culturally distinctive form of masculinity (induced) into the unconscious development of little boys’, and that Hegel and ‘feminist interpretation of psychoanalytic theory’ can help us grasp why. According to Pateman, ‘(t)he masculine sense of self is grounded in separateness (from femininity)’, and ‘Hegel showed theoretically in his famous dialectic of mastery and servitude that a self so conceived always attempts to gain recognition and maintain its subjective isolation through domination’. Men thus experience a need to ‘affirm themselves as masters’ and ‘prostitution is the public recognition of men as sexual masters’.26

This is not convincing. Even if we grant that the psychological mechanism which Pateman describes could perhaps lead to prostitution, her argument would only be effective against acts of prostitution motivated by a masculine desire to gain recognition and maintain identity by dominating the gender according to which men define themselves as the opposite. This appears to be a gross overtheorisation of men's willingness to pay for sex.

Even if we (generously) grant that this is in fact the mechanism behind all or most acts of prostitution, however, it is still not clear why it follows that prostitution is harmful. What Pateman has argued is that prostitution is ‘one of the most graphic examples of men's domination over women’, that is, that prostitution is a part of social life where it is clearly expressed that we live in a male dominated society. It is not clear, however, how this has any bearing on the harmfulness of prostitution, for even if B is a product of A, and A is harmful, it follows neither that B itself is harmful nor that B is indirectly harmful by reciprocally promoting A. For all Pateman has argued, prostitution could be a mere by product or a litmus test, which by itself is harmless. If Pateman seeks to argue not only that society at present harms women (which perhaps it does), but that prostitution is harmful, her argument fails.^viii

A way to supplement Pateman's argument, suggested by Debra Satz, is that prostitution is harmful because it is degrading, and since most prostitutes are women, prostitution degrades women (this is a species of the argument that B is indirectly harmful by reciprocally promoting A).29 There are, however, two serious problems with this further argument. First, it relies on a troubling form of collectivism in judging the prostitute as a representative of one of the groups to which she belongs.^ix Second, if prostitution is degrading, it seems that it must be degrading in virtue of something. Thus calling prostitution ‘degrading’ takes for granted, rather than establishes, that there is something troubling about prostitution. As such, we are back in the search for substantial reasons to believe that prostitution is harmful.^x

The economic dominance argument

•   P1: That which involves economic dominance is harmful.

•   P2: Prostitution involves economic dominance.

•     C: Prostitution is harmful

This is also an argument with strong intuitive appeal. Economic dominance, which we might define as the use of monetary power to subordinate a person to another person's will, seems harmful (P1). Since such subordination seems to be involved in prostitution (P2), it seems that prostitution is harmful (C).

I believe this argument can be put in at least three different ways, appealing to three different aspects of prostitution that supposedly give rise to economic dominance. Let's examine these separately.

First and most crudely it can be argued that there is something intrinsic to the roles of ‘buyer’ and ‘seller’ that tends to put the buyer, who has the money, in a dominant position over the seller, who must give up what she has in order to get the money she needs, and that this applies to prostitution. This is a weak argument, however, since it applies to a problematically large number of cases. Thus it is easy to come up with counterexamples. Consider, for example, a grocery store owner and a man buying bread or a drug dealer and a man buying drugs. In these cases, it is everything but clear that the buyer has the upper hand, even though the buyer supplies the money and the seller supplies the goods. As such, we cannot use the labels ‘dominator’ and ‘dominated’ categorically on either the buyer or the seller side, and as such, this cannot be used to establish that prostitution involves economic dominance.

An alternative reason why prostitution involves economic dominance could be that, at least in the majority of cases, there is a significant difference in economic power between the rich buyer and the poor seller, and it could be argued that this involves or makes likely that the rich party takes a dominant role in the transaction. This is also a weak argument, however, since we all take part in economically asymmetrical transactions on a daily basis, and we seem to do so without being harmed. Whenever I buy an airline ticket from KLM, an electronic device from Apple, or a hamburger from Burger King, I engage in a transaction where I have significantly less economic power than my trading partner. This does not harm me.

A third variant of the argument could appeal, not to the relative difference in economic power between the prostitute and the client, but to the absolute economic power of the prostitute, and to the fact that the prostitute might often be so desperately poor that in order to earn a living, she must satisfy all of her clients’ whims. Such cases are clearly tragic, but acknowledging this seems rather to be an argument that extreme poverty is harmful than an argument that prostitution is harmful, since—as in the exploitation argument—nothing in particular is said about the practice of buying and selling sex.

As such, it is unclear why it should follow from the nature of prostitution that the client holds a dominant position over the prostitute. Indeed, it seems that we might flip this common argument on its head and claim that the prostitute naturally holds a dominating position over the client. After all, what goes on in an act of prostitution is that two parties have sex, but one party, the client, is required to pay in order to be allowed to participate. If he will not pay, or he cannot pay, he is not allowed in. After the sex has come to an end, moreover, the client is left with nothing (but ebbing pleasure) while the prostitute is left with money.

Appeals to economic dominance, therefore, do not seem to establish that prostitution is harmful. To account for the alleged harm of prostitution, we need to say something more specific about the very actions involved in buying and selling sex specifically. I will now examine three arguments that do.

The selling one's body argument

•   P1: That which involves selling one's body is harmful.

•   P2: Prostitution involves selling one's body.

•     C: Prostitution is harmful.

This argument says something substantial and seemingly forceful about prostitution. It seems harmful to sell one's body (P1) and it also seems that prostitution involves just this (P2). As such, it seems that prostitution is harmful (C).

Before we can assess this argument, we must—to avoid equivocation—get a clear understanding of what we mean by ‘selling one's body’.

It seems that the phrase ‘selling one's body’ can mean at least three different things. It can mean (1) selling one's body in the same way that one sells other commodities, such that after one has sold it, one no longer has any claim on it and the buyer may dispose of it as he pleases. Alternatively, ‘selling one's body’ can mean (2) renting out one's body for a certain period of time without restrictions on its use in the rental period, or it can mean (3) renting out one's body for a certain period with restrictions on its use in the rental period.^xi

Selling one's body according to (1) is clearly harmful. It is very doubtful, however, if this is an apt description of what goes on in prostitution. Point (1) describes slavery, not buying and selling sex, and it is uncontroversial that slavery is harmful. The same goes for selling one's body according to (2), since there are clear restrictions on what a client can rightfully do to a prostitute. A client cannot rightfully beat up a prostitute any more than he can beat up a hairdresser or a plumber. (It is true that in many societies, violence against prostitutes is taken less seriously than violence against non-prostitutes. That, however, should speak against those societies, not against prostitution.) To the extent that prostitution involves selling one's body, it seems that it must be according to (3), which is a much weaker account of ‘selling one's body’ than the catchphrase hints to.

On this account, however, it is no longer clear that selling one's body is harmful, since prostitution is far from the only profession where bodies are sold in this sense. Pateman argues that prostitution is indeed singled out as the body selling profession, but in arguing for this, she compares the services offered by prostitutes solely with the services offered by counsellors.26 That is not a very interesting comparison, however, since counsellors offer some of the least bodily services on the market. More interesting professionals to compare with are dancers, masseuses, sumo wrestlers and football players. Though few would argue that these professionals are significantly harmed, it seems undeniable that they sell their bodies according to (3). As such, it seems that making money from bodily work is at least not categorically harmful.

To single out prostitution, one might twist the argument by saying that in the same way selling does not really mean selling, body does not really mean body. One might argue that what matters is not that prostitutes rent out their bodies as such, but that they rent out a specific part of their bodies, namely their genitals. This can seemingly single out prostitutes, since dancers, masseuses, sumo wrestlers and professional football players do not earn money from renting out and doing jobs with their genitals.

In reply to such an argument, Martha Nussbaum has offered the example of a colonoscopy ‘artist’ who is paid and consents to having her colon used by medical researchers to develop efficient and comfortable colonoscopy equipment. This, Nussbaum admits, would be a strange occupation indeed, but it would not seem harmful in the sense and to the extent that most of us believe that prostitution is harmful (even though, as Nussbaum writes, the colonoscopy artist is ‘penetrated by another person's activity—and, we might add, far more deeply penetrated than is generally the case in sex’).33 If Nussbaum is right, the fact that prostitution involves making money from using one's genitals is insufficient to establish that prostitution is harmful.^xii

An alternative suggestion could be that the harm lies not in the seller having her genitals interfered with, but in the seller having to interfere with the buyer's genitals. This distinguishes the prostitute from the colonoscopy artist. The problem with this suggestion, however, is that although it would not imply that the colonoscopy artist is harmed by the colonoscopy, it would imply that the medical doctor performing the colonoscopy is harmed—at least if he is paid by the colonoscopy artist for doing his job.^xiii This suggestion seems even less plausible than the suggestion that the colonoscopy artist is harmed.

A last suggestion falling under the ‘selling one's body’ category could be that the harm lies neither in the genitals of the prostitute nor in the genitals of the client, but in the interaction of their genitals. This would seemingly single out prostitution from all other body-selling professions, since prostitutes are presumably the only ones who make money from genital interaction. It is unclear, however, how it could be harmful that genitals A and genitals B touch and interact for payment if individually touching and interacting with genitals A and genitals B for payment is quite harmless. At least, it seems that if one wants to argue that such interaction is harmful, focusing solely on the bodily movements involved will not do the trick. To account for the alleged harm, then rather than looking merely to the body and the bodily movements, one should look to the movements’ sexual meaning and to the mental side of making money from providing sexual services, and seek to locate the harm here. This is the aim of the remaining two arguments.

The habitual faking argument

•   P1: That which involves habitual faking is harmful.

•   P2: Prostitution involves habitual faking.

•     C: Prostitution is harmful.

One psychological hardship associated with selling sex is that it requires one to fake one's sexual responses. Perhaps Nagel's mutual enjoyment theory (see ‘The objectification argument’), assuming it is correct, leads not to the client caring for the prostitute's enjoyment, but to the prostitute being required to pretend that she enjoys having sex with her client. This seems quite plausible, and according to Estes, it is a brutal fact about prostitution that ‘every visible response (of the prostitute) must address the client's desires and wishes’. This, Estes claims, can make the prostitute ‘cognitively and emotionally confused’ if it is done consistently and over time. Indeed, Estes argues, this can destroy a prostitute's sex life, and she asks, seemingly rhetorically, whether someone who has worked as a prostitute will ever be able to ‘‘switch on’ her feelings when with her lover’.9 To the extent that the prostitute will not, it seems that P1 and P2 are true, and thus that prostitution is harmful (C).

There are, however, problems with this argument as well. A first problem is that it is not always clear that ‘every visible response must address the client's desires and wishes’. Though some clients might demand this, others might not. As such, there seems to be limits to how much faking is required.

Regardless of the possibility of a lack of demand for excessive faking, however, we should concede that at least some faking is intrinsic to, or is made very likely by, prostitution. Thus it seems that a prostitute still could be led to making a habit out of faking, and thus that P2 remains.

Even if we grant that P2 is true, however, it is not clear that P1 is true. As in several of the above arguments, the allegedly harmful feature appealed to is also present in professions that we do not think of as harmful. A good example here is professional acting. An actress makes money from faking: from pretending that things are otherwise than they are. This can be rough: she can be required to play in a light-hearted comedy the day after a friend of hers has died or in a tragedy the day after she has gotten married. If she engages in this for decades, it seems that she could and would be making a habit out of faking. We do not, however, think of acting as harmful. On the contrary, we usually think of acting as enriching. A natural question to ask, then, is why the same cannot be true of prostitution. Prejudice aside, it does not seem impossible that a prostitute could handle her acting the same way actresses do and thus manage to keep her sex with a lover distinct from her sex with a client the same way an actress keeps the sorrow she expresses over Hamlet's death distinct from the sorrow she expresses at her friend's funeral. At least, an argument would have to be made as to why—granted the weak significance view of sex—a prostitute could not do this.

The habitual faking argument, therefore, seems not to be effective as long as it does not explain how faking while having sex is fundamentally different from faking in other areas of life. To make the case that it is, one must seemingly appeal to something in the very personal and emotional nature of sex.

The selling one's soul argument

•   P1: That which involves selling one's soul is harmful.

•   P2: Prostitution involves selling one's soul.

•     C: Prostitution is harmful.

If we translate ‘soul’ into less mystical terms, and use it to refer to our deepest values, emotions and character traits, then this argument has a plausible P1. The arch example of selling one's soul is perhaps to sell the position as one's closest friend. Close friendships are thought to flow from our deepest values, emotions and character traits, and this seems to be the reason why close friendships should not (or perhaps could not) be sold. The intimacy of sexual relations might make them share this characteristic with friendships (P2), and this might in turn explain why prostitution is harmful (C).

The problem with this argument is that it is forceful only on the strong significance view of sex. If the strong significance view is false, it is not clear why selling a close friendship is a good parallel to selling sex. On the weak significance view, in which casual sex is permitted, it would be fine to engage in sexual actions without being emotionally involved.

A counterargument to this reply could be that even if the weak significance view is correct, complete emotional detachment is not possible, at least not as long as the person involved has a healthy, non-repressed emotional life. There might, accordingly, be some personal elements included in all sex, even though these might not be sufficiently strong to warrant the strong significance view of sex. I believe this is a sound counterargument. Even if we concede that there are certain personal elements involved in all sex, commercial sex included, however, this needs not imply that prostitution is harmful—or, at least, not harmful to a significant degree. After all, people sell personal elements in a long line of professions that we do not consider harmful. Nussbaum provides the example of a philosophy professor, like herself, who ‘takes money for thinking and writing about what she thinks—about morality, emotion, the nature of knowledge’ even though these are ‘all parts of a human being's search for understanding of the world and oneself’.38 A philosophy professor, Nussbaum notes, sells her soul in this sense, and should expect, as part of her work, that strangers invade her private space: on the one hand, she could be facing students who are not worthy of her philosophical attention, yet still receive it for payment. On the other hand, she could experience unexpected arguments that shake her grounds in settings where she must remain calm and professional. A philosophy professor, therefore, seems to sell her soul, and the same might plausibly be said about professional musicians, authors, psychologists, priests, medical doctors, nurses, teachers and kindergarten workers. Granted the weak significance view of sex, it is not clear why a prostitute sells her soul to a larger extent than these professionals do. As such, we are still not given a convincing reason why prostitution is harmful.
