This book – Lucio Mansillo’s ROZAS, a “historical-psychological essay” is interesting to know about. The period in which Rosas and Sarmiento lived is really interesting, strange, and revealing, and if there is anyone who has not decided yet on an oral presentation topic, a historical investigation on this and on the way the terms civilization and barbarism are used would be both interesting and useful. And for that, the chapter on Sarmiento in Doris Sommer’s Foundational Fictions would be one good place to start. Also very useful is E. Bradford Burns’ The Poverty of Progress: Latin America in the Nineteenth Century. And with those two sources, you would have enough material for an oral presentation (of the size of presentation we are doing).
