My old prof Peter Carruthers shares some thoughts. Here’s one of his hypotheses:
Philosophers use the language of “argument” a lot. We tell our students that philosophy is all about learning how to distinguish good arguments from bad arguments, that philosophy will increase their ability to argue well, and so on. But the word “argument” does double-duty as a label for conflict. When one’s parents argue, this is not generally a good thing. Moreover, “argument is war” is one of Lakoff and Johnson’s famous structural metaphors. We defend our position, attack our opponent’s assumptions and so on. Since women tend, on average, to be less aggressive and competitive than men, and to be more inclined to cooperation, then the way philosophers talk about their discipline might be putting them off.
The idea should be readily testable, if any experimental philosopher were inclined to take this up. Two groups of students in a large intro class could be given a promotional flyer describing the philosophy major. The only difference between the two groups would be that one flyer would use “argument” where the other would use “reason” (“philosophy is all about distinguishing good reasons from bad reasons” etc.). The students could be asked to score how attractive they think the philosophy major looks on the basis of the flyer. If there are significant differences between the two groups, then that might suggest that it would be worthwhile making an effort to adopt the language of reason over argument.
It’s not clear to me that women are, on average, less competitive than men. Less aggressive, yes. Anyway, I’d like to see this experiment.
