Mr. Posnack's reach is indeed daring and impressived an evaluation of Communist economic teachings with a glance at the logical soundness of dialectical materialism; a review of Russia's political structure and development since the Revolution; a critique of the failings of capitalism; a plan for ever greater free enterprise based upon co-existence and aimed at the unification of peoples into a prosperous world community. Whether the author's reach exceeds his grasp may be open to question. But the Manifeild itself seems an inadequate target for a full-scale attack upon Marxist ideology. If the tendency of collectivism is to stifle initiative, the total psychological contrast between Soviet collectivism and American entrepreneurship goes far beyond initiative and embrace the deepest impulses of the psyche. Urging that taxes be lowered to encourage the free flow of wealth, the fact is cited that $100,000,000 has been poured into almost tax-free Puerto in Operation Bootstrap but is this economic progress or exploitation? Proposals to enable businesses and peoples to move to areas of incentive, transported by some subsidized international agency, seem more in keeping with Mr. Posnack's good intentions... Though not controversial, the book must surely challenge the global-minded citizen of whatever persuasion.
