Of the three “great debates” of post-Mao Chinese politics, on democracy, economics and epistemology, the last one became the most politicized and crucial because it was directly related to the basic question of the legitimacy of post-Mao policies. It began with the publication of an article, “Practice is the only standard for evaluating truth,” in Kuang-ming jih-pao on 11 May 1978. The article was signed by the paper's “special commentator” (t'e-yueh p'ing-lun yuan), and was reprinted the following day in People's Daily. However, there was nothing to indicate that the article was in any way exceptional until Teng Hsiaop'ing made its theme the centerpiece of his speech at the Army Political Work Conference on 2 June. After Teng's insistence on “seeking truth from facts” (shih-shih ch'iu shih) and his criticism of people “who talk about Mao Tse-tung's Thought all the time,” but do not emulate his practicality, the campaign emphasizing the importance of practice developed rapidly and in several directions. Conferences were held to explore its significance, new authoritative articles were published which defended and amplified the anti-dogmatic stance, and over the succeeding months a series of rather repetitive speeches by virtually every provincial secretary and military region commander appeared in People's Daily affirming Teng's position. Finally, in October 1978, “special commentator” articles appeared in People's Daily which called for the deepening of the struggle against the “gang of four,” claiming that their poison had affected even some who had opposed them politically.
