Is Desirism Really Rational?
I have said that desirism is a rational ethics, specifically, it is the recommendation to vet our desires or motivations rationally before acting. But there is another sense in which desirism might be claimed to be rational, namely, that anyone who is rational would, given sufficient information, likely be motivated to adopt desirism as their ethics. This latter is indeed a claim, and an empirical one, as opposed to the first assertion, which is really only a definitional stipulation. Thus, combining the two, the empirical thesis I am putting forward is that a rational and informed person would likely encourage everyone (including themself) to make their decisions about what to do based on a rational review of their desires—in a word, would encourage everyone to be (a) desirist.[1]
But I have
also said that desirism presumes atheism and amoralism. The question then
arises: Is this also just a stipulation (if a person is a theist or a moralist
then they can’t be a desirist by definition, just as a chemical consisting of five
hydrogen atoms or nitrogen can’t be water), or is it a substantive claim? I intend
it as the latter. It seems to me that a rational person would have good reasons for rejecting
both theism and moralism (i.e., belief in God and morality, by which I mean,
objective values). Thus my (second) claim is that it is unlikely that an
informed desirist would be a theist or a moralist (because that would be irrational
and desirists are by definition rational).
This may
seem false on its face. If the only stipulation for being desirist is to be
rational, then I would be claiming that theists and moralists are (or tend to
be) irrational. But that is not only insulting but just kind of dumb … isn’t it?
Aren’t there plenty of highly rational theists and moralists? Or, more
specifically, would not plenty of people claim that their belief in God or
morality is rational? So they could even call themselves desirists (if they had
some peculiar reason for wanting to appropriate this label) since they might advise
everyone to act on a rational basis and they happen to believe part of such a
basis would be belief in God or morality.
Well, I
guess I just have to bite the bullet(s) and argue that it is irrational
to believe in God or morality (or that people who believe in them are irrational
at least in that regard). This is not difficult for me to do. It is so easy to
refute the belief in God that I have not even bothered to present (the time-honored)
arguments (which is why it may have seemed to be merely a stipulation of
desirism). It takes more doing (in secular society or among the intelligentsia)
to refute the belief in morality, but only because “morality” has so many meanings
and because to be considered moral is widely taken to be flattering. So I have
had to make clear which kind of morality I specifically object to (namely,
morality in the sense of objective values), argue for its illusory nature, and strive
to convince that believing in it (as real) has consequences for self and
society most of us dislike.
So, could a
desirist be a theist or a moralist? Yes and no. Yes because desirism recommends
only that we be rational, and it could be thought an open question whether
belief in God or morality might be rational. But no because it is at least highly unlikely that such beliefs would
in fact withstand rational scrutiny. And, indeed, part of the appeal of
desirism is precisely that it rids us of fear of or reliance on God and of
moral intransigence and conflicts and guilt etc. But these are, in the end,
simply benefits of being rational (and hence part of its appeal, and so
there are after all reasons for being rational).
[1] An objectivist way of
putting the substantive claim would be that it is rational to be desirist.
I won’t be arguing for that, as I am a subjectivist about rationality, as I am
about morality.
