Philosophers rarely seem surprised or unsettled when I present my work on the morality of ethicists -- work suggesting that ethics professors behave no differently than other professors or any more in accord with their own moral opinions (e.g., here). Amusement is a more common reaction; so also is dismissal of the relevancy of such results to philosophy. Such reactions reveal something, perhaps, about the role philosophical moral reflection is widely assumed to have in academia and in individual ethicists' personal lives.
I think of Randy Cohen's farewell column as ethics columnist for the New York Times Magazine:
Writing the column has not made me even slightly more virtuous. And I didn't have to be.... I wasn't hired to personify virtue, to be a role model for kids, but to write about virtue in a way readers might find engaging. Consider sports writers: not 2 in 20 can hit the curveball, and why should they? They're meant to report on athletes, not be athletes. And that's the self-serving rationalization I'd have clung to had the cops hauled me off in handcuffs.(BTW, here's my initial reaction to Cohen's column.)
What spending my workday thinking about ethics did do was make me acutely aware of my own transgressions, of the times I fell short. It is deeply demoralizing.
Josh Rust and I have found, for example, that although U.S.-based ethicists are much more likely than other professors to say it's bad to regularly eat the meat of mammals (60% say it is bad, vs. 45% of non-ethicist philosophers and only 19% of professors outside of philosophy), they are no less likely to report having eaten the meat of a mammal at their previous evening meal (37%, in our study, vs. 33% of non-ethicist philosophers and 45% of non-philosophers; details here and also in the previously linked paper). So we might consider the following scenario:
An ethicist philosopher considers whether it's morally permissible to eat the meat of factory-farmed mammals. She read Peter Singer. She reads objections and replies to Singer. She concludes that it is in fact morally bad to eat meat. She presents the material in her applied ethics class. Maybe she even writes on the issue. However, instead of changing her behavior to match her new moral opinions, she retains her old behavior. She teaches Singer's defense of vegetarianism, both outwardly and inwardly endorsing it, and then proceeds to the university cafeteria for a cheeseburger (perhaps feeling somewhat bad about doing so).
To the student who sees her in the cafeteria, our philosopher says: Singer's arguments are sound. It is morally wrong of me to eat this delicious cheeseburger. But my role as a philosopher is only to discuss philosophical issues, to present and evaluate philosophical views and arguments, not to live accordingly. Indeed, it would be unfair to expect me to live to higher moral standards just because I am an ethicist. I am paid to teach and write, like my colleagues in other fields; it would be an additional burden on me, not placed on them, to demand that I also live my life as a model. Furthermore, the demand that ethicists live as moral models would create distortive pressures on the field that might tend to lead us away from the moral truth. If I feel no inward or outward pressure to live according to my publicly espoused doctrines, then I am free to explore doctrines that demand high levels of self-sacrifice on an equal footing with more permissive doctrines. If instead I felt an obligation to live as I teach, I would be highly motivated to avoid concluding that wealthy people should give most of their money to charity or that I should never lie out of self-interest. The world is better served if the intellectual discourse of moral philosophy is undistorted by such pressures, that is, if ethicists are not expected to live out their moral opinions.
Such a view of the role of the philosopher is very different from the view of most ancient ethicists. Socrates, Confucius, and the Stoics sought to live according to the norms they espoused and invited others to judge their lives as an expression of their doctrines. It is an open and little-discussed question which is the better vision of the role of the philosopher.
Update 1:17 PM: A number of philosophers have expressed variants of this position to me over the years, but Helen De Cruz has reminded me of Regina Rini's articulate expression of some of these ideas in a comment on one of my earlier posts.]
