The union view claims that love consists in the formation of (or the desire to form) some significant kind of union, a “we.” A central task for union theorists, therefore, is to cash out just what such a “we” comes to—whether it is literally a new entity in the world somehow comprised of the lover and the beloved, or whether it is merely metaphorical. Variants of this view perhaps go back to Aristotle (cf. Sherman 1993) and can also be found in Montaigne (1603/1877) and Hegel (1997); contemporary proponents include Solomon (1981, 1988), Scruton (1986), Nozick (1989), Fisher (1990), and Delaney (1996).
Scruton, writing in particular about romantic love, claims that love exists “just so soon as reciprocity becomes community: that is, just so soon as all distinction between my interests and your interests is overcome” (1986, p. 230). The idea is that the union is a union of concern, so that when I act out of that concern it is not for my sake alone or for your sake alone but for our sake. Fisher (1990) holds a similar, but somewhat more moderate view, claiming that love is a partial fusion of the lovers’ cares, concerns, emotional responses, and actions. What is striking about both Scruton and Fisher is the claim that love requires the actual union of the lovers’ concerns, for it thus becomes clear that they conceive of love not so much as an attitude we take towards another but as a relationship: the distinction between your interests and mine genuinely disappears only when we together come to have shared cares, concerns, etc., and my merely having a certain attitude towards you is not enough for love. This provides content to the notion of a “we” as the (metaphorical?) subject of these shared cares and concerns, and as that for whose sake we act.
Solomon (1988) offers a union view as well, though one that tries “to make new sense out of ‘love’ through a literal rather than metaphoric sense of the ‘fusion’ of two souls” (p. 24, cf. Solomon 1981; however, it is unclear exactly what he means by a “soul” here and so how love can be a “literal” fusion of two souls). What Solomon has in mind is the way in which, through love, the lovers redefine their identities as persons in terms of the relationship: “Love is the concentration and the intensive focus of mutual definition on a single individual, subjecting virtually every personal aspect of one's self to this process” (1988, p. 197). The result is that lovers come to share the interests, roles, virtues, and so on that constitute what formerly was two individual identities but now has become a shared identity, and they do so in part by each allowing the other to play an important role in defining his own identity.
Nozick (1989) offers a union view that differs from those of Scruton, Fisher, and Solomon in that Nozick thinks that what is necessary for love is merely the desire to form a “we,” together with the desire that your beloved reciprocates. Nonetheless, he claims that this “we” is “a new entity in the world…created by a new web of relationships between [the lovers] which makes them no longer separate” (p. 70). In cashing out this web of relationships, Nozick appeals to the lovers “pooling” not only their well-beings, in the sense that the well-being of each is tied up with that of the other, but also their autonomy, in that “each transfers some previous rights to make certain decisions unilaterally into a joint pool” (p. 71). In addition, Nozick claims, the lovers each acquire a new identity as a part of the “we,” a new identity constituted by their (a) wanting to be perceived publicly as a couple, (b) their attending to their pooled well-being, and (c) their accepting a “certain kind of division of labor” (p. 72):
A person in a we might find himself coming across something interesting to read yet leaving it for the other person, not because he himself would not be interested in it but because the other would be more interested, and one of them reading it is sufficient for it to be registered by the wider identity now shared, the we.[3]
Opponents of the union view have seized on claims like this as excessive: union theorists, they claim, take too literally the ontological commitments of this notion of a “we.” This leads to two specific criticisms of the union view. The first is that union views do away with individual autonomy. Autonomy, it seems, involves a kind of independence on the part of the autonomous agent, such that she is in control over not only what she does but also who she is, as this is constituted by her interests, values, concerns, etc. However, union views, by doing away with a clear distinction between your interests and mine, thereby undermine this sort of independence and so undermine the autonomy of the lovers. If autonomy is a part of the individual's good, then, on the union view, love is to this extent bad; so much the worse for the union view (Singer 1994; Soble 1997). Moreover, Singer (1994) argues that a necessary part of having your beloved be the object of your love is respect for your beloved as the particular person she is, and this requires respecting her autonomy.
Union theorists have responded to this objection in several ways. Nozick (1989) seems to think of a loss of autonomy in love as a desirable feature of the sort of union lovers can achieve. Fisher (1990), somewhat more reluctantly, claims that the loss of autonomy in love is an acceptable consequence of love. Yet without further argument these claims seem like mere bullet biting. Solomon (1988, pp. 64ff) describes this “tension” between union and autonomy as “the paradox of love.” However, this a view that Soble (1997) derides: merely to call it a paradox, as Solomon does, is not to face up to the problem.
The second criticism involves a substantive view concerning love. Part of what it is to love someone, these opponents say, is to have concern for him for his sake. However, union views make such concern unintelligible and eliminate the possibility of both selfishness and self-sacrifice, for by doing away with the distinction between my interests and your interests they have in effect turned your interests into mine and vice versa (Soble 1997; see also Blum 1980, 1993). Some advocates of union views see this as a point in their favor: we need to explain how it is I can have concern for people other than myself, and the union view apparently does this by understanding your interests to be part of my own. And Delaney, responding to an apparent tension between our desire to be loved unselfishly (for fear of otherwise being exploited) and our desire to be loved for reasons (which presumably are attractive to our lover and hence have a kind of selfish basis), says (1996, p. 346):
Given my view that the romantic ideal is primarily characterized by a desire to achieve a profound consolidation of needs and interests through the formation of a we, I do not think a little selfishness of the sort described should pose a worry to either party.
The objection, however, lies precisely in this attempt to explain my concern for my beloved egoistically. As Whiting (1991, p. 10) puts it, such an attempt “strikes me as unnecessary and potentially objectionable colonization”: in love, I ought to be concerned with my beloved for her sake, and not because I somehow get something out of it. (This can be true whether my concern with my beloved is merely instrumental to my good or whether it is partly constitutive of my good.)
Although Whiting's and Soble's criticisms here succeed against the more radical advocates of the union view, they in part fail to acknowledge the kernel of truth to be gleaned from the idea of union. Whiting's way of formulating the second objection in terms of an unnecessary egoism in part points to a way out: we persons are in part social creatures, and love is one profound mode of that sociality. Indeed, part of the point of union accounts is to make sense of this social dimension: to make sense of a way in which we can sometimes identify ourselves with others not merely in becoming interdependent with them (as Singer (1994, p. 165) suggests, understanding ‘interdependence’ to be a kind of reciprocal benevolence and respect) but rather in making who we are as persons be constituted in part by those we love (cf., e.g., Rorty 1986/1993; Nussbaum 1990).
Along these lines, Friedman (1998), taking her inspiration in part from Delaney (1996), argues that we should understand the sort of union at issue in love to be a kind of federation of selves:
On the federation model, a third unified entity is constituted by the interaction of the lovers, one which involves the lovers acting in concert across a range of conditions and for a range of purposes. This concerted action, however, does not erase the existence of the two lovers as separable and separate agents with continuing possibilities for the exercise of their own respective agencies. [p. 165]
Given that on this view the lovers do not give up their individual identities, there is no principled reason why the union view cannot make sense of the lover's concern for her beloved for his sake.[4] Moreover, Friedman argues, once we construe union as federation, we can see that autonomy is not a zero-sum game; rather, love can both directly enhance the autonomy of each and promote the growth of various skills, like realistic and critical self-evaluation, that foster autonomy.
Nonetheless, this federation model is not without its problems—problems that affect other versions of the union view as well. For if the federation (or the “we”, as on Nozick's view) is understood as a third entity, we need a clearer account than has been given of its ontological status and how it comes to be. Relevant here is the literature on shared intention and plural subjects. Gilbert (1989, 1996, 2000) has argued that we should take quite seriously the existence of a plural subject as an entity over and above its constituent members. Others, such as Tuomela (1984, 1995), Searle (1990), and Bratman (1999) are more cautious, treating such talk of “us” having an intention as metaphorical.
