By these acts Leto II removed himself from the evolutionary succession. He did
it with a deliberate cutting action, saying: "To be independent is to be
removed." Both twins saw beyond the needs of memory as a measuring process, that
is, a way of determining their distance from their human origins. But it was
left to Leto II to do the audacious thing, recognizing that a real creation is
independent of its creator. He refused to reenact the evolutionary sequence,
saying, "That, too, takes me farther and farther from humanity." He saw the
implications in this: that there can be no truly closed systems in life.
