A professor of history at the City University of New York Graduate Center, Diggins (The Rise and Fall of the American Left
) provides an original reappraisal of Ronald Reagan from the conservative perspective. Throughout, Diggins discovers nuances that have heretofore escaped notice by most other Reagan scholars. For example: in appraising Reagan's reaction as California governor to '60s radicals, Diggins is the first writer to acknowledge the extent to which the onetime movie star shared common ground with rebels on campuses nationwide. Reagan, with his reverence for Thomas Paine and passion for limiting the reach of government, was—on at least one level—more than sympathetic when Berkeley protesters chanted, "Two, Four, Six, Eight, Organize to Smash the State!" Although a fan of Reagan's, Diggins doesn't hesitate to be critical—as when he discusses Reagan's attitude as president toward environmental issues, which Diggins characterizes as "puzzling" and "disastrous." (Diggins notes that Reagan's record as governor of California, where he allied himself with old guard Republican conservationists, was far more environmentally-friendly.) Overall, Diggins does a superb job of tracing Reagan's intellectual development from old school New Dealer to thoughtful, Emersonian libertarian, and also firmly establishes Reagan's credentials as a major architect of communism's final collapse. 13 photos.
