Given the continuing poor state of philosophy when it comes to feminist issues, it seems necessary to watch out for this sort of thing. I just picked up The Cambridge Companion to Carnap, and happened to glance through the bibliography. There turned out to be a surprising gap. By most accounts, Susan Haack's 1977 paper on Kantian elements in Carnap's Aufbau was one of the more important early studies contributing to the current Carnap revival, and the current Carnap revival is the topic of the book. But Haack is absent from the lengthy bibliography. It may be an innocent accident, it may mean nothing, but with philosophy's depressing history of ignoring the contributions of women, one can't help but worry when it seems like there might be yet another instance of the problem. Haack is even around, and I thought pretty well respected; usually the historical pattern has been that women in philosophy have sometimes been able to get recognition among their contemporaries but have almost always been been ignored by later generations.
