Stephen was born in Cornwall, in the beautiful but rainy Southwest of England, back in the days when Stevie Wonder and Steely Dan were topping the charts.
After a decade studying and teaching philosophy, he was awarded his PhD in metaphysics from the University of Cambridge in 2001. Before dedicating himself to writing and parenting, Stephen made ends meet as a diplomat, negotiating international treaties on behalf of Her Majesty.
Stephen has since written essays, features and reviews on many philosophical, ethical and scientific subjects, from human nature to robot warriors and animal rights. He writes regularly for the Financial Times, and has also written for the New York Times, the Guardian, Wired and many others. He has appeared on BBC Radio 3, BBC Radio 4, Deutschlandradio, NPR, PBS, CBC and elsewhere.
His internationally acclaimed first book, Immortality: The Quest to Live Forever and How It Drives Civilization, was published in English and other languages in spring 2012. Stephen, who speaks fluent German, lives in Berlin with his wife Friederike von Tiesenhausen and their many daughters. He is a Fellow of the Royal Society of Arts.
