" It is from motion that we gain our sense of both space and time. The right hemisphere seems to be essential for both, and the capacity for each is linked with the other.69 The left hemisphere’s focus, however, narrows both. If I want to focus precisely on a particular element in my environment, clearly and in sharp detail, I have not just to home in on it in space, but to immobilise or freeze it in time, too. It becomes like a snapshot (what the French call, suggestively, a cliché). The more precise anything is, the less content it has: ‘the more certain our knowledge the less we know.’ The left hemisphere’s experience is fragmentary and therefore taken out of the flow of experiential life, and tends towards stasis. It is concerned with the moment of the ‘kill’. However, outside of this glare of the spotlight, things carry on living, moving and changing. "
