Building on his previous work in Liberal Fascism, Goldberg makes the case that tribalism, populism, nationalism, and identity politics aren't new phenomena but merely evidence of civilization returning to its natural state, like an overgrown garden. Following the thread of Lockean and Rousseauian thought, he argues that modern populism is really the same Romantic reaction to the Enlightenment that never really faded, now dressed up as reality TV.
Well-researched (the appendix is nearly a fifth of the book's bulk) and well-written with Goldberg's usual wit and sarcasm, it's an entertaining read.
