> Such behavior is chronicled in a notorious chapter of his autobiography, Surely You’re Joking, Mr. Feynman! (“I adopted the attitude that those bar girls are all bitches, that they aren’t worth anything, and all they’re in there for is to get you to buy them a drink, and they’re not going to give you a goddamn thing”).
This suggests that the attitude discussed was how Feynman thought about woman. However, the chapter is about trying out that attitude as a temporary experiment — and Feynman quickly rejects the approach precisely because is feels too sexist/dehumanizing (iirc, it's been a while since I read the source).
None of that is to disagree with the article's overall point – I don't have an informed opinion on the matter. But I did find that quote a bit misleading.
