In many ways this is a question Gilles Deleuze (1925–95) himself might have asked. Deleuze took nothing for granted and insisted that the power of life – all life and not just human life – was its power to develop problems. Life poses problems – not just to thinking beings, but to all life. Organisms, cells, machines and sound waves are all responses to the complication or ‘problematising’ force of life. The questions of philosophy, art and science are extensions of the questioning power of life, a power that is also expressed in smaller organisms and their tendency to evolve, mutate and become.
