The Rainbow of Desire (1995)
Context: 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. The self-knowledge thus acquired allows him to be the subject (the one who observes) of another subject (the one who acts). It allows him to imagine variations of his action, to study alternatives. 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.
