This is, unfortunately, a title which does little more than call to mind the many other books which have appeared on this subject within the past few years-- unfortunately, because many of the remarks of these 13 ""men of distinction,"" as the editors-- again, rather unfortunately--term themselves and the eleven contributors, are both new and valuable. There are truly ""useful essays"" on the contemporary aspects and historical backgrounds of the important social, political, and economic forces for change in South and Central America. The emphasis, inadvertently or otherwise, is heavily upon Mexico and Brazil, but the implications extend to most if not all of our southern neighbors. Perhaps outstanding among the authorities represented here are: Gilberto Freyre, Daniel Cosio Villegas, Stanley Ross, Robert Alexander, and Arturo Uslar-Pietri. The keynote throughout is realistic optimism: ""change is no longer a dismaying challenge, but a beckoning stimulus."" One hopes this will not be one of the books which will necessarily be defeated by the presently intense competition for attention within this complex area of concern.
