"This examination of two of the most important movements in Spanish American thought - Romanticism and Positivism - provides an excellent picture of the difficulties that Hispanic Americans have faced since their independence and succinctly presents the main currents of thought of various Spanish American philosophers regarding the solution of their problems. Included are the ideas of such men as Sarmiento in Argentina, Lastarria in Chile, Mora in Mexico, and Bello in Venezuela for the Romantic period, and Barreda and Sierra in Mexico and Alberdi and Echeverria in Argentina for the Positivist period." - back cover
I don't know much about Latin American political philosophy, or I didn't. But this book is a lovely and very readable introduction. Out-of-print though, and rather hard to find.
