'After more than twenty thousand days in this world I'm back to basics. My body is dated equipment and I ride it as though I've borrowed it for the day, taking its senses on a test flight.' Song of the Ghost in the Machine is a free-wheeling philosophical poem that emerged during the walks Roger Horrocks took over a year of his life. In this striking, one-of-a-kind work, he seeks to engage as directly as possible with the basic elements of life - the self and the body, sleeping and waking, death and belief, and above all the strangeness of thought ('the ghost in the machine'). In his curious look at life from unexpected angles, he draws upon state-of-the-art science and philosophy, doing so in a lively, accessible, down-to-earth way.
