It is one of Sartre's greatest strengths that his declared aim was 'to write for his own time'. From the 1940s onward, he became ever less interested in 'timeless' questions, and ever more concerned to explore the concrete realities of his own age. This engagement with the contemporary makes it particularly tempting to consider what Sartre's responses to the events of our own age would be. Ever since his death in 1980, those of us who have drawn insight and inspiration from Sartre's works have tended to ask how Sartre might have judged particular political developments. And because of the central place given to violence in his thought, as well as his detailed reflections on the Second World War and the wars in Algeria and Vietnam, it is only natural to ask how Sartre would have responded to the appalling events of 11 September 2001 and the subsequent 'war on terror'.
