'Both the lecture itself and the controversy it spawned are complex phenomena, and in his editions of Snow's lecture and of the most famous response to it, by the literary critic F. R. Leavis, Stefan Collini has carefully and skillfully disentangled the many strands. The tale he tells is instructive in many respects - and perhaps more important now than it was when Leavis gave his response, fifty years ago.' Alan Jacobs, Books and Culture
