五四运动,是伟大的思想解放运动,社会主义学说形成为强大的政治思潮,为抵制这一思潮的进一步传播,胡适与早期共产主义者展开了那场有名的“问題与主义”的论战。关于论战的实质和意义,学术界已作过较为充分的研究,兹不赘述。这里是把问題推到前面去,围绕论战的缘起,以及与之有关的问題,作进一步的研究。 The May 4th Movement was a great liberation movement of ideas. The socialist theory formed a powerful political trend of thought. In order to resist the further spread of this trend of thought, Hu Shih and the early Communists launched the famous controversy on “issues and doctrines.” As for the substance and significance of the debate, the academic community has done a more adequate study and will not repeat them here. Here is to push the issue to the front, around the origin of the controversy, as well as the related issues for further study.
