This book was begun in London at the London Consortium which was then directed by Steven Connor. It was completed in Berlin, while I was a fellow at the ICI Berlin Institute for Cultural Inquiry. Both cities and both institutions were vital to the book's development, and I wish to thank each guiding voice and source of encouragement I encountered within them. My time spent at the ICI was invaluable to the project's advancement; I am hugely grateful for the resources and opportunities my fellowship there afforded. The middle sections of Chapter 2 revisit and reformulate elements of a previously published article, 'Thinking Room and Thought Streams in Henry and William James' Textual Practice 26:5 (2012): 871-889, and I thank the journal for permission to reuse that material here. I also want to thank by name and niche the following: Christien for love and longing; Adam for piano songs; Richard for five years and then some; Sophie for tremendous friendship at tremendous distances; Greg for guitars and whiskey; Laura for brill Brum cos stuff; the Cowley pack for Cowley magic; Alex for Pusha T; Daniel for glam literality; Nahal for calm and chocolate; Hadi for blue Farsi; Robert for notes that don't exist; Bobby for death on the dance floor; Netta for life on the dance floor; and David for ping pong. But if my admiration and adoration is for these dear friends and many unmentioned others, then this book is for my brothers Ben Harlow and Kieran Gavin, and my sister Lucy Sutton. Here's 'a little something', the least I could do.
