Watching an improviser. Watching impulses, choices, all that brain activity unfold and seeing absolutely none of it. We are witnesses to bodies only - the rest is just taking someones words and then believing them. We have to assume that what they say is what they think. There is no other way to prove it to be different. In that world, that presupposed fact of interaction, deception - whether conscious or more likely not - we live largely by trust. But with the body the reality of its makeup, its function, and its owners way of using it is apparent right now from the start. We are presented with truth. And in this world of improvisation, nothing can be in a more immediate and present state than the performer. The creator. The instigator.
