The best tribute a writer can have is the knowledge that he has changed others' percepts, affects and concepts (the three aspects of a body, according to Deleuze, glossing Spinoza). If the blogs in our network are anything to go by, it's evident that anyone who has sensitively engaged with Luke's work over the last twenty months or so has been changed, and changed for the better, by the contact with his writing. I hope such a change is evident in what I produce here, because it is certainly apparent in the way in which I engage with the world in a renewed way.
