To the Sisterhood destiny was biology and maternal influence the strongest of all life-forces. Accordingly, Jessica was thoroughly trained for motherhood: she learned to understand and control her own organism so as to be the fittest possible biological mother, and-still more essential to the Bene Gesserit design- she learoed to observe, understand, and hence control others, and by this means to keep everybody, men, women, princes, and potentates, psychological "children" to her perpetually dominant "motberliaess." Jessica, however, confounded her teachers by transcending their concept of maternity. The Bene Gesserit thought her a shockingly unSisterly rebel against their careful discipline, but actually Jessica did not so much revolt as evolve into another dimension of selfhood, that of Hetaira. Because she became a true companion to her mate, Duke Leto Atreides, she freed herself for a much fuller, more substantive motherhood than the Bene Gesserit projected; as Hetaira Jessica chose to bear the son her lover wanted, not the daughter planned by the Sisterhood, for as Hetaira Jessica knew that the loving intimacy of equal, free selves was the only true generative force in the universe. Jessica's Hetaira role was emphasized by the fact that Duke Leto made her his Lady concubine but never his Lady wife; few societal sanctions supported (or confined) her Archetypal compamonate vitality. Lady Jessica remained Hetaira all her adult life. She never stopped loving her Duke, not even decades after his death, and she returned to the Atreides' home planet, Caladan, whenever she could. More significantly, she instilled the need to be Hetaira into all her descendants: into Paul Atreides, who welcomed Chani as his "companion;" into Leto II and Ghanima, twin Hctairae to each other; and most notably and tragically into Alia, whose Hetaira nature betrayed her to the Baron Harkonnen's seductive intrapersonal companionship. Ironically, it was against this Abominable companionship that Jessica displayed her fullest, most irresistible Amazonian strength. Lady Jessica first discovered her Amazonian potential when she fled, pregnant, into the Arrakeen wilderness. Fremen women, thoroughly liberated to the world of men, showed Jessica that she, too, could survive Dune's rigors. As Amazon she mastered both the shifting sands of Dune's deserts and the shifting tides of Imperial politics. As Amazon she retired to Castle Caladan during her son's reign, and there, in those familiar surroundings, used the Amazon's resourceful objectivity to outthink and at last outgrow her Bene Gesserit conditioning. The depth and range of her matured Amazonian powers were especially evident du
