Phil. thesis undertaken in Oxford and conferred as such in May 1994. Firstly, I would like to thank Prof. Wolfgang Wieland through whom my interest in the Topics was fITst aroused in one of his colloquiums at the University of Heidelberg and who was my first teacher in the study of Aristotle and Plato. The comments made by my two D.Phil. examiners, Mr Christopher Kirwan and Prof. Mario Mignucci were of great help. In addition, the suggestions of the publisher's anonymous reader helped make the thesis more readable. I am grateful to the British Academy· for enabling me to study for a D. Phil. at Oxford; to the Studienstiftung des deutschen Volkes which supported me throughout studentship; and to the editors of Philosophia antiqua for accepting my thesis for publication. I came to Oxford fITst as a Visiting Student in 1990 and I feel that my stay here was of great advantage to my studies and in particular to this book, and there are many teachers to whom I am indebted. I should like to thank Dr. Katherine Morris and Dr. Stephen Blamey, from whom I learned much about formal logic, and Dr. David Charles, with whom I studied Aristotle's syllogistic. Then, as a D.Phil. Student, I had the chance to learn a great deal about Hellenistic philosophy, esp. in Prof. 10nathan Bames' classes on Sextus Empiricus and Prof. Michael Frede's classes on Stoic Logic. A paper based on Chapter Two was read in a doctoral seminar held by Prof. Bemard A. O. Williams who made useful comments. I am also grateful for the comments of the participants of my lecture series held in Trinity Term 1996 at the University of Oxford which coincided with the revision of the book. I am of course especially indebted to the supervisors I had whilst writing my thesis. I would like to thank the late Mr. Michael Woods who supervised my work for one term in my second year. Sadly, he died prematurely; he was a very gentle man, and I am personally very indebted to him. I also have to thank Prof. Michael Frede who supervised my work in the two remaining terms of the second year; through his initially heavy critique of my interpreta tion of hypothetical syllogisms I had to find more and more arguments in favour of it which was certainly beneficial to my thesis. I also thank my wife Claire for all sorts of editorial help in turning my thesis into a book. Most and above all, I would like to thank Prof. 10nathan Barnes, who supervised my work in my fITSt and third year. I have learned a great deal from him about how to treat philosophical texts. As will become clear from the references in my thesis I also learned very much from his articles, especially those on hypothetical syllogisms; they were of great help to me in developing my own thesis. Having tutorials with him was always very helpful and stimulating. I suspect that I am more indebted to him than he is even aware. PAUL SLOMKOWSKI Brasenose College, Oxford July 1996
