"Nothing is known for certain, Isarda. All knowledge is illusion—purpose is a meaningless word, a mere sound, a reassuring fragment of melody in a cacophony of clashing chords. All is flux—matter is like these jewels. (She throws a handful of gleaming gems upon the golden surface; they scatter. When the last jewel has ceased to move, she looks up at him.) Sometimes they fall into a rough pattern, usually they do not. So as this moment, a pattern has been formed—you and I stand here speaking. But at any moment that which constitutes our beings may be scattered again."
