ABSTRACT
Of all the behavioural material that a supreme non-material being or the genome has furnished us with, surely none is as significant or communicative as the human face. Not only is it a flexible mechanism for expressing a range of emotions but it is also the primary focus of who we are. For it to be damaged (for example by disease or accident) is thus a double blow, impairing our outward expressive abilities but also undermining what it is we can express (given the self is our primary message). Or it compels us as producers and consumers of communication to think differently about how we communicate.
