The premise is that four women of varying closeness to each other who also studied philosophy together helped push back against the analytic turn in British philosophy and the apparently nefarious influence of A.J. Ayer’s version of logical positivism.
The four women as fascinating and clearly did important work (obviously, Murdoch is well known beyond philosophy), but the thesis of the subtitle is not really upheld. Did they bring philosophy back to life? They could have, but the authors don’t necessarily make that case (and even undercut it by mentioning several men who came back from World War II and felt driven by what they saw and experienced to turn away from analytic philosophy). In an unfortunate choice, the focus on Anscombe’s friendship and professional relationship with Wittgenstein risks making her appear as a moon, albeit an important one, in his orbit. I am convinced their work was important and interesting, but their influence, particularly on the (still) male-dominated world of philosophy is poorly documented, nor is it suggested that they created a cohort of female disciples to batter down the patriarchal door.
