Thomas Harrington's Public Intellectuals and Nation-Building in the Iberian Peninsula 1900-1925: The Alchemy of Identity, is a timely and important addition to current debates on nationhood and national identity in today's Spain and Portugal. Through a detailed historical treatment of the work of four preeminent nationalist "catechisms" of the early twentieth century, Harrington sheds much-needed light upon the architecture of competing discourses of national identity in today's Peninsula. Perhaps the book's greatest strength, however, is the way it allows us to observe the parallel and often surprisingly interconnected genesis of that region's supposedly radically distinct codes of collective belief.
