Joined Warwick's Philosophy Department in 1993 and has held a Personal Chair since 1998. Areas of philosophy that especially interest him include the philosophy of the emotions and the philosophy of time. He draws inspiration from Bergson's twofold conception of the task of philosophy: to enhance the power to act and live and to extend our perception of the universe.
In 2018 Bloomsbury Press published Bergson. Thinking Beyond the Human Condition. This book has received an Outstanding Academic Titles Award (OAT) 2018 by CHOICE. The book seeks to illuminate Bergson's view that philosophy is the discipline of thinking that makes the effort to think beyond the human condition so as to extend our perception of the universe. The book explores Bergson on time and freedom, on memory, on his reformation of philosophy in Creative Evolution on religion, on ethics, and on education and the art of life.
Professor Ansell-Pearson has been appointed the co-general editor of a publication venture by Bloomsbury Press. This is the translation into English of the recently published series by PUF (2016-18) of three public lecture courses by Bergson: The History of the Idea of Time (1902/3), The History of Theories of Memory (1903/4), The Evolution of the Problem of Freedom(1904/5). He is working on this project with Donald A. Landes.
He has recently completed an essay on 'Bergson and Philosophy as a Way of Life', to be published in a new volume of essays on Bergson by Cambridge University Press, Interpreting Bergson: Critical Essays, and edited by Alexandre Lefebvre and Nils Schott. He is researching an essay on Bergson on the emotions for a volume of essays entitled The Bergsonian Mind being edited by Yaron Wolf and Mark Sinclair for Routledge.
With Federico Testa he is editing the English edition and translation of Jean-Marie Guyau’s text, The Ethics of Epicurus (1878). With him he is also working on an essay on Guyau and ethics for the Oxford Handbook of Modern French Philosophy (edited by Mark Sinclair and Daniel Whistler).
In recent years Ansell-Pearson has made a contribution to Nietzsche studies with a focus on his middle writings. He has written the Afterword to the new edition and translation of Dawn published by Stanford University Press in 2011 and as part of The Complete Works of Friedrich Nietzsche. His study of Dawn, co-authored with Rebecca Bamford, will be published in 2020 with Wiley-Blackwell. In 2018 Bloomsbury Press published Nietzsche's Search for Philosophy: On the Middle Writings. With Paul Loeb he is editing a new volume of essays on Thus Spoke Zarathustra for Cambridge University Press to be published in their 'Critical Guides' series. The volume will showcase new research.
