"I argued in Part 1 that Mao had devised the concept of the 'principal contradiction' because, unlike Marx, who was never in doubt as to the basic conflict underlying Western society in his own day (that between the proletariat and the bourgeoisie), Mao lived in a world characterized by a bewildering variety of social strata, deposited layer by layer in the course of a century of rapid change. Chinese and world society are not likely, in the coming decades, to grow less complex, nor is the interaction between countries and cultures likely to grow less intense. In this context, Mao's ideas about contradictions may provide, if not a map, then a compass, for charting the contours of a changing reality. At the same time, Mao himself, as I have noted repeatedly (and as he remarked more than once), was full of contradictons. In an effort to sum these all up, let me conclude with what may appear to benothing more than a bit of folklore, but has perhaps a deeper significance. I quoted above Mao's statements, and those of the Tsing-hua University Middle School Red Guards, regarding the Monkey King, Sun Wu-k'ung, at the beginning of the Cultural Revolution. Mao had repeatedly used Monkey as a political symbol in earlier years, and prior to the Great Leap, virtually all of these references were negative. Indeed, in May 1938 he went so far as to identify Monkey with the 'fascist aggressors' who would be buried in the end beneath the 'Mountain of the Five Elements' constituted by the peace front. But suddenly, in 1958, the tone changed, and Mao declared: Monkey paid no heed to the law or to Heaven (wu-fa wu-fien). Why don't we all learn from him? His anti-dogmatism [was manifested in] daring to do whatever he liked … Perhaps that sums up, better than any other single image, the essence of Mao's political role, and its profound ambiguity. Eternal rebel, refusing to be bound by the laws of God or man, nature or Marxism, he led his people for three decades in pursuit of a vision initially noble, which turned increasingly into a mirage, and then into a nightmare. Was he a Faust or Prometheus, attempting the impossible for the sake of humanity, or a despot of unbridled ambition, drunk with his own power and his own cleverness? More of the latter than used to be imagined, no doubt, and yet something of the former as well. Even today, the final verdict, both on the man and on his thought, must still remain open."
