In The Age of The Crisis of Man, a new book by n + 1 co-founder and editor Mark Greif, the author examines the life and death of the concept of “man,” aka a unified humankind that could be said to suffer from particular conflicts. It was born in the thirties, with the rise of Fascism, but persisted for decades, eventually giving way to a more diversified view of humanity. In Tablet, Adam Kirsch dives into Greif’s arguments.
