Theatre has nothing to do with buildings or other physical constructions. Theatre - or theatricality - is the capacity, this human property which allows man to observe himself in action, in activity. Man can see himself in the act of seeing, in the act of acting, in the act of feeling, the act of thinking. Feel himself feeling, think himself thinking.
