This book is a product of many years’ work on the Critique of Aesthetic Judgement. In particular, I learned so much over many of those years from jointly teaching the text at the University of Essex along with Michael Podro, whose very modus operandi was an exhibition of reflective judgement. Our audience was a mixed group of Philosophy and Art History M.A. students, whose questions and suggestions helped us gradually clarify how reflective judgement operates. In more recent years I have taught the text to upper-level undergraduate students at Essex and discussed a range of related issues with M.A. and Research students. I am grateful to all of these students, whose perseverance and willingness to express puzzlement have helped me make some progress in determining the indeterminate. I am particularly grateful to Michael Podro for his support as an interlocutor, colleague and friend. The preparation of the final copy of this book led to a fruitful and enjoyable cooperation with a number of readers. Principal among these were James Corby, Maria Prodromou and Elin Simonson, each of whom read the text in its entirety and gave me extensive comments, valuable suggestions and corrections. The acuity of their suggestions, enthusiasm for the project and generosity in time and attention was remarkable. I am also very grateful to Dana MacFarlane and to John Walshe for helpful suggestions on aspects of the book. Finally, I would like to thank the team at Continuum, especially Sarah Campbell, Tom Crick and P. Muralidharan (in order of my acquaintance with them) for their efficient and helpful handling of this project. Despite all of this, any mistakes are, without doubt, my own.
