Current Research

In recent years I have made a specific contribution to Nietzsche studies with a focus on Nietzsche's middle writings. I share in the observation of Havelock Ellis that the works Nietzsche produced between 1878 and 1882 represent the maturity of his genius, and I am interested in what becomes of our appreciation of Nietzsche as a thinker and writer when we focus on these works, such as The Wanderer and His Shadow and Dawn.

In 2018 Bloomsbury Press published Nietzsche's Search for Philosophy: On the Middle Writings. In this study I provide new insights into the nature of Nietzsche's philosophical practice, including his commitment to a new Enlightenment and the passion of knowledge, his philosophy of modesty, his conception of philosophical cheerfulness, and his interest in Epicurus and the practice of heroic-idyllic philosophising.

I have 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. My study of Dawn, co-authored with Rebecca Bamford, will be published in 2020 with Wiley-Blackwell. Nietzsche's text is a path breaking work and an exercise in modern emancipation from fear, superstition, hatred of the self and the body, the short cuts of religion, and the presumptions of morality. However, it is no exaggeration to claim that for the greater part of Nietzsche-reception Dawn has been the most neglected text in Nietzsche’s corpus, and perhaps for the following reasons: it deploys no master concept, it does not seek an ultimate solution to the riddles of existence (indeed, it warns against such a strategy), its presentation of themes and problems is highly non-linear, and it states its case for the future subtly and delicately, proposing a programme of change through slow cures and small doses. Although there is no master concept at work in Dawn, and no overarching method (but a plurality of methods that add up to an experimental philosophy), the text may be better for their absence, helping to constitute one of Nietzsche’s most subtle and delicate experiments at writing and thinking.

Continuing this work on the middle writings I am now researching an essay on Nietzsche and Voltaire for a volume of essays on Nietzsche being edited by James I. Porter for a new series entitled Cambridge Studies in Literature and Philosophy.

In 2018 Bloomsbury Press published Bergson. Thinking Beyond the Human Condition. This book has received an Outstanding Academic Titles Award by CHOICE. The book seeks to illuminate Bergson's view that philosophy is the discipline 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.

I have 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). I am working on this project with Donald A. Landes.

I have 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. The essay takes its inspiration from Pierre Hadot’s insight that Bergsonism is not an abstract, conceptual philosophy but a philosophy that takes the form of a new way of seeing the world. I am researching an essay on Bergson and the emotions for a volume of essays entitled The Bergsonian Mind being edited by Yaron Wolf and Mark Sinclair for Routledge. My focus is on Bergson's account of the relation between time and the emotions; the extensive role that sympathy occupies in his philosophy; his construal of the relation between reason and the emotions; and his original conception of creative emotion.

With Federico Testa I am editing the English edition and translation of Jean-Marie Guyau’s text, The Ethics of Epicurus (1878). With him I am also working on an essay on Guyau and ethics for the Oxford Handbook of Modern French Philosophy (edited by Mark Sinclair and Daniel Whistler).
