A THERAPEUTIC ELIMINATION OF “BELIEF” AND “DESIRE” FROM CAUSAL ACCOUNTS OF ACTION Mark Curtis University of East Anglia School of Politics, Philosophy, Language and Communication Studies Department of Philosophy This thesis is submitted for the degree of Doctor of Philosophy June 2016 This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognise that its copyright rests with the author and that use of any information derived there from must be in accordance with current UK copyright law. In addition, any quotation or extract must include full attribution. Acknowledgements and Dedication My gratitude, firstly, to my thesis supervisors Eugen Fischer and John Collins. Eugen, as my unstinting primary supervisor, gave short shrift to my occasionally woolly thinking, detached me from my own dogmas and challenged me to raise the standard of my scholarship. Any academic merit that this thesis displays I owe to his guidance. Thanks also to colleagues, faculty and staff at the University of East Anglia, for revealing conversations in both formal and informal settings. Among others I must mention Lewis Clarke, Jessica Dollman, Gareth Jones, Janis Loschmann, Andrei Nasta, Liz McKinnell, Mihai Ometita, Sylvia Panizza, Fiona Roxburgh, Maria Serban, Sidra Shahid, Simon Summers and Odai al Zoubi. I am incredibly grateful to my wife, Karen, without whose emotional and material support I could never have embarked on this project. This work is dedicated to the memory of my late father, John Curtis, who imbued in me the sense that life should be marked by continual learning, curiosity and enquiry.
