Prevost 158: "The meeting of two human beings generates interactions of the highest complexity. Nothing could be more courageous, in artistic activity, than to risk a performance with no foreknowledge of the outcome and no certainty of personal and collective responses. It takes a rare kind of foolhardiness to risk all in this way. As a direct confrontational exercise for a beginner, a novice, or the experienced player, such a display of [lack of?] inhibition might have psychological benefits [...] But to base an aesthetic, a life's work, upon such a premise demands courage or foolishness. Such a spirit of freedom may be in tune with the times and may herald some wider flowering of human expression. At other times it may be popularly perceived as a madness at the margins of cultural life."
