The reciprocity of the virtues stems from a particular way of understanding the kinds of things that virtues are.7 For Aristotle, a virtue in the broadest sense is an attribute by which a living being is fit for the mode of life proper to its kind.8 In the strictest sense, a virtue is an attribute of beings that live by choosing â humans â that fits them for living well through choice.9 Or, as Aristotle puts it, virtue finds a âmeanâ of acting and feeling on the occasions one should, about the things one should, toward the people one should, for the purposes one should, and in the manner one should.10
Finding the mean takes wisdom. Virtues have good standing goals, like being forthright with the truth, but calling that goal good is a truism â like saying an archerâs goal is to hit the target â since as yet it is indeterminate.11 Practical wisdom is for discerning in a particular case just what such a goal would actually amount to, turning a good but indeterminate goal into a determinate goal that is still good.12
Sometimes we speak loosely of virtues, though, and call some people forthright, even when âbluntâ or âbrusqueâ would be more accurate, just because they strike us as stereotypically âforthright.â Aristotle calls attributes like these ânatural virtues,â and in this looser sense, even children and animals have their virtues.13 To say that virtue finds a mean, though, is to say that one chooses and acts so as to suit the situation at hand. Virtues of that sort â what Aristotle calls âgenuine virtueâ and âvirtue in the strict (literally, chief) senseâ â are intelligent, and not dispositions to stereotypical behavior.
But in that case, no intelligent virtue floats in a vacuum; forthrightness that isnât tactful and benevolent isnât the excellence of forthrightness, but just bluntness â it doesnât look where itâs going, so to speak, but bungles and blusters its way through.14 In order for wisdom to find even one mean, it has to be ready to find the mean of other virtues too.15 And it is at this point that Aristotle draws the conclusion in the epigram:
So it is clear from what we have said that one cannot be good, in the strict sense, without wisdom, or wise without virtue of character. But then the argument that the virtues are separate from each other comes undone, which one might make on the grounds that the same person is not naturally suited for all the virtues and therefore will acquire one virtue before another. This is what happens with natural virtues, but not with those virtues by which one is said to be good without qualification, since as soon as there is wisdom, which is a single thing, there will be all the virtues.
(NE VI.13, 1144b30â1145a2)
Nowadays, we call this idealization the reciprocity of the virtues. An idealization is just what it is, since it simplifies away the limitations of our wisdom in the actual world, where often in finding the mean we can do no more than avoiding doing the worst,16 and where we might do better at finding the mean of generosity than the mean of courage, say, or at finding the mean of fairness than the mean of generosity.17 And again, Aristotle knows it. The reciprocity of the virtues is not a generalization of what virtuous people are like.
So then, what is the use of this idealization? From this point on, I have to set aside what Aristotleâs own use of it is, because I find it too hard to tell. Instead, I will argue that its best use is to highlight the distinct challenge of fusing interdependent tasks, like playing louder at tempo. First, though, I want to develop the idea that the virtues are interdependent in a way thatâs worth highlighting, before taking a closer look at interdependence in Section 2.
1.2 The Mean, Reciprocity, and Interdependence
Beverly has chaired an oral exam for Allan, a graduate student in her department. He passed, but the examiners agree that while he is smart and hardworking, Allan will probably struggle with advanced work in the discipline and should consider leaving the program. How should Beverly get this message across to Allan?18
Think about why Beverly should need to get this message across in the first place: Allan deserves to know the truth, to make an informed decision about how to spend these valuable years of his life. So the manner in which she should tell Allan the news is one that will serve the purpose for which she should tell him. To tell the truth as one should and for the purpose one should are elements of the âmeanâ of forthrightness, and these elements are interdependent â they cannot be understood one by one, but only together â as are all the other elements of the mean. At the level of a single virtue, doing the things one should, at the time one should, regarding the person one should, for the purpose one should, and in the manner one should are a matter of fusing interdependent tasks, like playing louder at tempo.
We can take this thought further: Since the purpose for which Beverly should give Allan the news is to help Allan, the mean of forthrightness must also include giving the news in a constructive way. If Beverly gives Allan the news for the purpose she should, then she cannot just make sure the message sinks in, come what may; that would be thoughtless and cruel, not helpful. Nor can she just give Allan the news as she herself would want to hear it, which might be obtuse and unsympathetic; nor in an offhand way, which would be tactless and unfeeling; nor so as to minimize her own discomfort, which would be cowardly and self-indulgent. And so on. To tell the truths one should, to the persons one should, when one should, in the manner one should, and for the purpose one should â to find the mean of forthrightness â one must tell the truth in a way that is also thoughtful, tactful, benevolent, courageous, and temperate.19 And of course, these further goals are also indeterminate: Beverly wonât find the mean of tact by making the message so soft that it doesnât sink in; and so on. Finding the mean of forthrightness and finding the mean of tact are not discrete tasks to be done merely simultaneously, but interdependent tasks to be fused. This point, of course, corresponds to the thesis that the virtues are reciprocal, which reflects the interdependence of virtue on a second level: To find even one mean, it is not enough to find just one mean.
The thesis that virtue finds a mean is a thesis about interdependence within a virtue, and the reciprocity of the virtues is a thesis about interdependence between virtues. Interdependence on the second level arises from the elements on the first level. Beverly cannot be forthright as she should be without also delivering the news kindly and courageously; she cannot deliver the news with the kindness or courage that she should without also being forthright.20
For all these reasons, I am going to understand the reciprocity of the virtues as the thesis that to have any virtue is to have every virtue because the virtues are inter...
