Earp, Brian D. and Savulescu, Julian 2017. Love drugs: Why scientists should study the effects of pharmaceuticals on human romantic relationships. Technology in Society,
In 2015, we published an article entitled “The Medicalization of Love,” in which we argued that both good and bad consequences could be expected to follow from love’s medicalization, depending on how the process unfolded. A flurry of commentaries followed; here we offer some preliminary thoughts in reply to the more substantial of the criticisms that were raised. We focus in particular on the nature of love itself as well as the role it plays (or should play) in our lives; we also touch on a number of practical issues concerning the likely effects of any plausible “real-life” love drugs and conclude with a call for careful regulation.

Please note that Plato, as represented in this passage, “was referring not to the love of women, ‘such as the meaner men feel,’ but to the love of a man for another man, which was the Greek ideal for the purest form of love” (Coontz 2005, at 56). The essay cited here is based on a longer book by the author: CoontzS. Marriage, a History: From Obedience to Intimacy or How Love Conquered Marriage. London: Penguin Books; 2005.

38. In another essay, Nyholm does seem to appreciate this point. Specifically, he writes that his aim has been not to analyze love from
a Sidgwickian “point of view of the Universe”—or a Nagel-inspired wholly objective “view from nowhere” [but rather] to ask whether or not the values that we do in fact have in relation to love are such that, as we now tend to think about love, it would be possible and advisable to try to create and maintain the sort of love that we seek with the help of biomedical enhancements. And my argument has been that, with respect to this set of values, the particular intrinsic goods that we associate with love are not ones we can deliver into each other’s hands with the help of biomedical enhancements. . . . This is perfectly compatible with its possibly being the case that, in some supposedly more enlightened future time-period, we might collectively look back upon the values I have appealed to, and then regard them as having been rather silly and old-fashioned.

As Erik Parens has recently argued, there is often something useful to be gained from “oscillating between the insights afforded by the subject and object lenses,” in a habit of thinking he calls “binocularity.” See ParensE.

50. Ferraro suggests that our focus on neurochemistry makes it seem as though “love” can be located within the brain of a single individual and modified accordingly: “It becomes affective and, ultimately, individualistic, a matter of how one feels” (see note 22, Ferraro 2015, at 486). But let us just grant that love should be seen as something that only exists, in some sense, between individuals—that it requires that I care about your well-being for its own sake, for example. It can still be meaningful to ask, we would contend, what the effects of certain neurochemical substances (as applied to the brain of a single individual) would be on the love between individuals understood in this way. For example, there is evidence that SSRIs can sometimes blunt not only people’s “lower-level” sex drives but also their “higher-level” ability to care about the feelings of others, i.e., as a side effect (see note 5, Earp et al. 2013). Thus, a drug administered to a single individual—and which has a certain kind of effect on the way that person “feels”—nevertheless can have meaningful implications for more complex, interpersonal conceptions of love than Ferraro thinks we are aware of. In short, love doesn’t have to be “located in a single individual’s brain” for interventions into that single individual’s brain to affect love (on a more robust conception) in significant ways.

66. They might, for example, make it easier for couples to see each other’s perspective. Or they might help them notice new (or rediscover old) appealing aspects of their partners’ personalities—aspects that had previously been obscured by a self-absorbed mindset. Such biological interventions would, in short, make “true” love much more probable.
