郭沫若同志对中国古代社会性质的研究,花了几十年功夫,看法几经改变,最后才把奴隶社会与封建社会的分界线定在春秋、战国之交。这个结论当然还不能说就是最后真理,尤其是郭老在有的具体论述中,确实还存在一些不够完善之处。因此,我们今天本着党的“百家争鸣”的方针,对郭老的学说实事求是地进行讨论,以期更好地解决这一问题,不但是允许的而且是必要的。 Comrade Guo Moruo spent decades on the study of the nature of ancient Chinese society. After several changes, his demarcation line between slavery and feudal society was finally set at the turn of the Spring and Autumn Period and the Warring States. Of course, this conclusion can not be said to be the final truth, especially in some of Guo Lao's specific expositions. There are indeed some imperfections. Therefore, today, in line with the principle of “one hundred schools of thought” of the party, we should pragmatically discuss Guo's theory with a view to better solving this issue, which is not only permissible but also necessary.
