This history and appraisal of SNCC by twenty-six year old Jack Newfield, a founder of SDS and a partisan of SNCC, seems to prove the axiom that came out of the Berkeley Rebellion-- ""never trust anyone over thirty."" For where the press stops short, Newfield moves on. He makes clear the origins and motives of those thousands committed to equal rights and a moral foreign policy; he assays the conditions in American life which have made for the growth of such socialist-oriented, anti-totalitarian groups as Students for a Democratic Society. Portraits of the leadership, Robert (Moses) Parris, Stoky Carmichael, Tom Hayden and others, lend, by their examples, to his thesis that these are the best young workers on the job of constructing tomorrow's America in good and meaningful ways. Sympathetic but never uncritical, Newfield's first book proves him a builder, a free and hardthinking young man whose company older liberal reporters ought to keep.
