Geoffrey Lloyd engages in a wide-ranging exploration of what we can learn from the study of ancient civilisations that is relevant to fundamental problems, both intellectual and moral, that we still face today. How far is it possible to arrive at an understanding of alien systems of belief? Is it possible to talk meaningfully of 'science' and of its various constituent disciplines, 'astronomy', 'geography', 'anatomy', and so on, in the ancient world? Are logic and its laws universal? Is there one ontology - a single world - to which all attempts at understanding must be considered to be directed? When we encounter apparently very different views of reality, how far can that be put down to a difference in conceptions of what needs explaining, or of what counts as an explanation, or to different preferred modes of reasoning or styles of inquiry? Do the notions of truth and belief represent reliable cross-cultural universals? In another area, what can ancient history teach us about today's social and political problems? Are the discourses of human nature and of human rights universally applicable?What political institutions do we need to help secure equity and justice within nation states and between them? Lloyd sets out to answer all these questions, and to convince us that the science and culture of ancient Greece and China provide precious resources to advance modern debates.

劳埃德（G．E．R．Lloyd,1933～）

英国剑桥大学教授,长期从事古希腊科学思想史研究。1987年始执“古代科学和哲学”讲席,1989年起任达尔文学院院长。2000年从这两项职位上退休,任荣誉教授。1997年因“对思想史的贡献”而被英国王室赐封爵士。

劳埃德教授著述颇丰,已出版十余部专著,其中大多数是研究希腊科学和医学,或者以希腊科学和医学为素材,探讨科学思想、科学哲学、科学社会学等问题。其著作的特点是：历史叙述条理清晰,史料翔实,运用恰当；探讨问题视角新颖独特,反映出科学哲学与科学社会学的最新研究动态。

劳埃德教授近十多年来的研究兴趣从古希腊科学延伸到中国古代科学,著有《早期希腊科学：从泰勒斯到亚里士多德》（1970）、《道与名》（与美国著名中国科学史学者席文教授合著,2002）、《受制于疾病的想象：希腊思想研究》（2003）、《无可辩驳性的错觉：古代希腊、中国和今天的智慧与道德》（2005）、《古代希腊和中国科学中的原理与实践》（2006）、《认知的变种：对人类思维统一性和多样性的反思》（2007）等。
