"In his enhanced identification with revolutionary youth, Mao no longer found the Party's standard" from the top down" approach to mass mobilization acceptable, and in spontaneously rebuking Liu and Deng and ordering the work teams withdrawn, he authorized a momentous departure from previous traditions of Party-mass linkage. Having ventured this innovation, however, he found it impossible either to allow the rebels to consummate their victory or to permit the entire experiment in spontaneous mobilization to be negated. Instead, from 1968 through 1976 he vacillated, sometimes permitting repression of the "revolutionary masses," sometimes kicking over the traces and permitting the masses to rise in relatively untrammeled anarchy (up to a point); as a result, mass mobilization became devalued either as a mechanism for elite implementation of policy or for the purpose of popular monitoring of deviant elites. Similarly, it was his prescient recognition of the problem of his own aging and debility that led Mao to attempt to designate his own heir apparent well in advance and to encourage the rise of revolutionary successors in a generational sense, but having undertaken such preparations he found them in direct conflict with his own fierce will to live, and thus repeatedly reversed them. On the issues of both mobilization and succession, we have argued that although part of the reason for Mao's oscillatory tendencies has to do with the constraints of a complex political reality, basically he was afflicted by his own crippling ambivalence. The result was an unusually protracted and debilitating crisis of succession."
