I. Langton is wrong, I think, in taking Herbert’s claim to being a moral saint at face value. What Herbert describes is an apathy to worldly pleasures; having no desires, she finds the moral law too easy to follow, and she complains that in the absence of struggle, morality loses its worth. This is an important point. But one might wonder whether there is not a difference between the value of a virtuous disposition reached through struggle, and one reached through heartbreak. Langton describes Herbert as doing her duty from the motive of duty; but it is not clear that this is the case. Herbert does her duty because she has no temptations to avoid it. But does this show—should we take it to show—that Herbert really has no non-moral motives and so must be acting from the motive of respect for the moral law? Langton interprets respect as having the purely negative function of silencing non-moral motives; and she insists that respect is neither itself a motive for moral action, nor a feeling. While the second of these claims is slightly debatable, it is almost certainly wrong (see Andrews Reath and Daniel Guevara on this point). The first claim is simply false—respect has a positive aspect, namely self-esteem. That Herbert does not feel self-esteem, in turn, might cast some doubt on her moral sainthood. For one thing: apathy of this sort might well itself be a passion, a passion that blinds one to its true nature.
Langton is also wrong, I think, to interpret apathy (at least as Herbert describes it) and nihilism as either products or correlates of the virtuous disposition. I see no reason to think that Herbert’s letter indicates a freedom from pathological impulses. And in this connection, it is not entirely clear that Kant was wrong to accept his friend’s diagnosis of Herbert as having suffered a romantic shipwreck. Let me suggest a possible diagnosis, based on the evidence, though without claiming that it is accurate. Imagine that you have been raised to fulfill moral norms. You have read a great deal of Kant, and this has reinforced your sense that it is important to follow those moral norms. But something goes wrong in your life: your great love goes sour. (It is true that there are all sorts of other issues, issues of gender inequality and the de-personification of women, that are involved in Herbert’s love loss. That does not, however, change the psychological effect of it as a heartbreak.) And so you lose interest in life. The things that once you enjoyed, you no longer enjoy. Nothing holds any interest for you. By the time the possibility of love is rekindled, you no longer care—you have become dead to it. But you still go on living and moving in the world, and so you live and move based on those rules, those moral norms you have always followed. Now that you want nothing that tempts you away from them, they are easy to follow; but you follow them simply as learned responses, acting on auto-pilot. If this is a feasible picture—and I submit that it is more feasible than the idea that Herbert was a moral saint, as such are rare, if even existent—then the state she describes is pathological, it is feeling laden, and it is a derangement (though not in the patronizing sense Kant seemed to have in mind). This apathy is not the strength not to be tempted by one’s sensible inclinations that Kant describes; it is, rather, a complete surrender to them.
II. I suspect that Langton unhelpfully conflates two issues. First, Kant’s commitment to treating persons as ends in themselves. Second, Kant’s views of women. There is no doubt that Kant thought women were inferior, that patriarchy was the proper form of society, and that relations between the sexes are not pure relations between persons. It is true that these views likely influenced Kant’s behavior in this situation. (It goes without saying that Kant was not exactly unusual in this regard, which is obviously no excuse, but also not a condemnation of his philosophy.) It is true that, had Kant been committed to treating all persons, regardless of gender, as ends in themselves, he would have acted differently. But this means it is also true that, had Kant fully worked out the implications of his moral philosophy in opposition to his social prejudices, he would have been a better man. If anything, though, this is a point in favor of his moral philosophy, if a large point against his anthropology. (But admittedly, this seems tied to a deeper feminist criticism of Kantian-style ethics, which I never fully understood.)
Langton argues, in a deeply evocative manner, that Herbert was struggling with a society in which, as a woman, she faced the constant threat of losing her status as person in the eyes of others. I fully agree that this kind of society is not a good society; that all human beings deserve the chance to be judged on their acts regardless of gender. And so there is much to consider in Langton’s further argument: if Herbert had to lie in order to go on being treated as a person, then her lie may be justifiable. Perhaps this is so—I do not think Kant’s prohibition against lying should be taken as universal, and were he better attuned to the gender politics of the time, and their wrongness, he may have recognized this as a problem case. But this is also not so clear cut. The lying in question is lying about a former relationship to a person with whom Herbert has developed a deep mutual trust. Herbert is right to fear that telling the truth would undermine her status as person in the eyes of the other. But we might note also that she tells the truth, and does so because she cannot bear withholding it and violating the trust. And this is precisely as Kant says it should be: to withhold the truth would corrupt her soul. Her situation may be a lose-lose one, and one that is perhaps not best framed in terms of the negative consequences of the truth (loss of personhood before the other) versus the negative consequences of the lie (corruption of the soul). But for Herbert, certainly, the situation is already in those terms. And Kant is not entirely wrong to point out that, if her love does not finally come to respect her, then perhaps he never really loved her, or at least not enough.
III. Langton is wrong, I think, in the criticism that Kant’s failure to offer a compelling reason to live—Kant’s failure, in other words, to reply to Herbert’s initial question—is a failure of his philosophy. Herbert writes to Kant—a man whom she asks whether he never thought it “to be worth the bother to marry, or to give your whole heart to anyone, or to reproduce your likeness”—with a mix of request of moral guidance and relationship advice. That Kant had no idea how to deal with the latter—or how to deal with the former as applied to the latter—was to be expected.
I am aware of many students—perhaps some readers of this are or were such students—who, when encountering a particularly impressive professor, start to think of that professor as having the answers to all of life’s questions, as a person that they can come to with all their problems. In the student’s mind, the brilliant professor becomes sage, psychologist, counselor, friend, parental figure, etc., all rolled into one. Such a feeling appears in the background of Herbert’s letters. Kant failed to live up to this standard; most of us do. Perhaps it is not wrong to expect philosophers to have better thoughts about “the meaning of life” than others; but few really do, and it is certainly wrong to expect philosophers to be able to give answers with the proper degree of sensitivity and psychological insight. It is fairly apparent—especially from her second letter—that Herbert is hoping to learn something specific from Kant: how his philosophy, particularly his moral philosophy, can act as substitute for love and marriage. But certainly Kant never offered it as such a substitute. It is reasonable to assume that if Kant remained a loveless bachelor, this was not as a result of his moral views, nor was it seriously aided by them. What Herbert wants from Kant, Kant the man cannot give, and Kant the philosopher has no grounds for giving.
Let me note a brief analogy: Langton might reply that I, like Kant, am simply trivializing Herbert’s serious philosophical objection to his moral philosophy through a patronizing dismissal of her letters on psychological grounds. I hope that I am not doing that. But I am recognizing something fairly obvious—that there is a psychological level to Herbert’s letters that Langton simply leaves out. Keep in mind that today, philosophy professors are given clear instructions: if a student comes to you with suicidal tendencies, you should refer them to the Mental Health office; the people there are trained professionals (yeah, ok, universities also have legal concerns). I suspect that, had he had such an option, Kant would have taken it. But he did not have this option, and he failed to deal with the situation appropriately.
But it is also true that Kant did not offer psychoanalytic tools. And the moral law is not a complete prescription for living a full life. That it fails in this regard is hardly a good criticism; morality places limits on the interests we ought to pursue, and it imposes some positive duties on us, but it does nothing else. It does not tell us how to spend a Saturday afternoon any more than it tells us how we are to find pleasure in life, or a positive reason to go on living, after having lost it. Why should we expect this of Kant? If anything of this is to be found in his moral philosophy, it is only in the sense that morality offers self-esteem as its own reward. Herbert felt none of this. Should we conclude that Herbert’s apathy was pathological, and so blinded her to the proper feeling for the moral law? Or should we rather conclude that Kant was wrong in thinking that virtue does reward us? I leave the question open, but I do not find evidence in Herbert’s letters to support the latter interpretation.
