Foreword WhetherornottherewasanactualrelationshipbetweenearlyChinesethoughtand early Greek thought is difficult to determine. But we can really claim that there is analogical relationship between early Chinese thought and early Greek thought. Even with regard to the concepts of Yin and Yang which have been regarded by mostscholarsforalongtimeanduptonowasverypeculiarChineseideas,wecan findthatthereisanalogicalrelationshipwiththeconceptsofthehotandthecoldand thedryandthewetinearlyGreekthought.1Therefore,Istronglybelievethat,ifwe systematically and profoundly try to do comparative research into early Chinese thoughtandearlyGreekthought,weshouldmeetmanysurprisingdiscoveries.And this will help us not only to find many comparable thoughts between the two, but alsotosolvethepuzzleswhichhaveremainedforunderstandingbecauseofthelost andthelackofdocumentsoneitherside. DirkL.Couprie’snewbook,WhentheEarthWasFlat:StudiesinAncientGreek and Chinese Cosmology, is a great attempt in this aspect. In this volume, he continues the research of his earlier work, Heaven and Earth in Ancient Greek Cosmology,andmakesadetailedanddeepstudyofflatearthcosmology.Whilein thepreviousbookhepaidmoreattentiontohowsphericalearthcosmologyreplaced flatearth cosmology andwas acceptedin early Greek thought,inthenew book he devotes much more discussion to the question of how flat earth cosmology has explained all kinds of puzzles of astronomy. It is precisely in this context that he devotesanindependentandspecialparttothestudyofChineseflatearthcosmology, calledthegaitiansystem,whichwascontainedinanancientChinesework,ZhouBi Suan Jing. He makes use of his extensive knowledge of ancient astronomy when studying its thoughts related to flat earth cosmology deeply and professionally, so that although I am a Chinese person, I become a layman with respect to him regarding this Chinese ancient work. But, I dare say, it is by his new book that he illustrates how a comparative research between early Chinese thought and early 1SeeNieMinli(2016). ix x Foreword Greekthoughtmayprovideusefulmaterialtoremedythedeficiencyofliteratureon bothsides.

Now,Ireceivethelastdraftofhisnewbook,WhentheEarthWasFlat:Studiesin Ancient Greek and Chinese Cosmology, which is just what he promised in 2016. I believe this work will be a new beginning in the comparative studies of ancient Western thought and ancient Chinese thought, which tells us about the similarities and differences between their cosmologies. Dirk Couprie tends to stress the differ- ences.Inmyopinion,however,toinquireforthesimilaritieswillgiveusevenmore inspiredideasthantoinquireforthedifferences.
