This book is a study of the origins and development of Greek science, focusing especially on the interactions of scientific and traditional patterns of thought from the sixth to the fourth centuries BC. The starting point is an examination of how certain Greek authors deployed the category of 'magic' and attacked magical beliefs and practices, and these attacks are related to their complex background in Greek medicine and speculative thought. In his second chapter Dr Lloyd outlines the development, and assesses the significance, of the theory and practice of argument in early Greek science, and he follows this with a study of the development of empirical research. Finally the author confronts the question of why the Greeks invented science: what precisely was their contribution to science, and what social, economic, ideological and political factors had a bearing on the growth of science in Greece.

This book was first published in 1991. The study of ancient science and its relations with Greek philosophy has made a significant and growing contribution to our understanding of ancient thought and civilisation. This collection of articles on Greek science contains fifteen of the most important papers published by G. E. R. Lloyd in this area since 1961, together with three newer articles. The topics range over all areas and periods of Greek science, from the earliest Presocratic philosophers to Ptolemy and Galen. In each case the article is preceded by an introduction that assesses scholarly debate on the topic since the original publication. Professor Lloyd also suggests modifications and developments to his own position in the light of those debates and his own further research.

How were the aims of philosophy and the responsibilities of philosophers conceived in ancient Greece and China? How were the learned elite recruited and controlled; how were their speculations and advice influenced by the different types of audiences they faced and the institutions in which they worked? How was a yearning for invulnerability reconciled with a sense of human frailty? In each chapter of this fascinating analysis ancient Greek and Chinese ideas and practices are used as a basis for critical reflections on the predicaments we continue to face today, with a particular focus on the key Greek ideas of the equal participation of all citizens in the political process, and on the key Chinese one of a dedication to the ideal of the welfare of all under heaven

Western philosophy and science are responsible for constructing some powerful tools of investigation, aiming at discovering the truth, delivering robust explanations, verifying conjectures, showing that inferences are sound and demonstrating results conclusively. By contrast reasoning that depends on analogies has often been viewed with suspicion. Professor Lloyd first explores the origins of those Western ideals, criticises some of their excesses and redresses the balance in favour of looser, admittedly non-demonstrative analogical reasoning. For this he takes examples both from ancient Greek and Chinese thought and from the materials of recent ethnography to show how different ancient and modern cultures have developed different styles of reasoning. He also develops two original but controversial ideas, that of semantic stretch and the multidimensionality of reality.

Dr Lloyd writes for those who want to discover and explore Aristotle's work for themselves. He acts as mediator between Aristotle and the modern reader. The book is divided into two parts. The first tells the story of Aristotle's intellectual development as far as it can be reconstructed; the second presents the fundamentals of his thought in the main fields of inquiry which interested him: logic and metaphysics, physics, psychology, ethics, politics, and literary criticism. The final chapter considers the unity and coherence of Aristotle's philosophy, and records briefly his later influence on European thought. This is a concise and lucid account of the work of a difficult and profound thinker. Dr Lloyd's business is only with the essentials; but he does not shirk the difficulties which arise in their interpretation, nor does he invest Aristotle with a spurious modernity

The Symposia Aristotelica were inaugurated at Oxford in 1957. They are conferences of select groups of Aristotelian scholars from the UK, USA and Europe, and are held every three years. In 1975 the meeting was held in Cambridge and was devoted to Aristotle's psychological treatises, the De anima and the Parva uaturalia. The members of the conference discussed some of the much debated problems of Aristotle's psychology and broached important new topics such as his ideas on imagination. Dr Lloyd and Professor Owen have collected and edited the papers presented to the Symposium and provided an analytical index.

Summary After a preliminary discussion of some of the problems of the nature of reason and argument and the difficulties of investigating them, this paper uses the rich evidence from ancient civilisations, Greece and China especially, to explore the relationship between reasoning and culture. While argument and persuasion are evidently widespread in all human populations, the modalities they take may differ depending on the differing pragmatic circumstances in which they are conducted – the audiences and interlocutors in question and the aims of persuasion. Those circumstances may give rise to different modes of argument and styles of reasoning. While Chinese persuaders typically target rulers or those in authority, some Greek ones had to try to persuade a general public who, in some situations, decided the issue by taking a vote. That, it is argued, may help to explain the main way in which Greek arguments were distinctive when compared with those we find in other ancient civilisations. The suggestion is that the axiomatic-deductive mode of argument that was developed by some Greek philosophers and mathematicians was a reaction against what were perceived as the merely persuasive modes cultivated by orators, sophists and politicians in the context of public debate.
