The text ‘I must not fear. Fear is the mind-killer.’ was printed in English and Arabic on stickers that were then posted on street furniture in London. The text is part of the Bene Gesserit Litany against Fear; from Frank Herbert’s science fiction novel Dune. Herbert’s fictional universe was used by him to discuss ideas of power, politics, religion and ecology and is heavily critical of the use of politics and religion as methods of imposing social cohesion and reinforcing Other-ness. This work takes these themes and uses them to critique current climates of fear and misunderstanding. The translations have been done using the ‘Translate...’ tool in Microsoft Word and could be faulty, highlighting the problems associated with attempting to take ideas across cultural and linguistic boundaries, and the sacredness, or otherwise, of texts.
