當大部份研究對於身體義肢的討論皆從外部著手，也就是探討人體以各種技 術物件做義肢性的延伸，《沙丘救世主》的探討卻從内部開始，以主角保羅的神 諭意識，來描寫人與腦内意識的交織。故事強調保羅與生倶有預視未來的能力， 並在發生意外失明後，持續依賴此種能力來在黑暗中觀看。然而矛盾的是，雖然 保羅本人依賴預知視力來觀看，但他卻處於反對義肢的想法當中，反對使用一般 義眼。他認為使用著他腦内的預知視力可維持自然身體的完整性，但從史提格勒 的技術觀點來看，這種完整性從未出現，因為人總是以義肢身體存在著。史提格 勒以電影意識的概念探討了人的意識以蒙太奇方式處理記憶的過程，第三記憶總 以人造義肢的方式增補著意識。以此看來，保羅使用預知意識增補失明後的空白， 讓他看見周遭事物，正實踐了義肢身體的使用。

While most discussions on the prosthetic body approaches from the outside, namely the prosthetic extension of the human in all forms of technical objects, the story of Dune Messiah depicts the interlacement of man and the prosthesis inside the human brain, Paul Atreides’s oracular consciousness. Laying emphasis on Paul’s supernatural power of foretelling the future, the fiction portrays how he employs oracular vision to see in the sightless dark after being blinded in an accident. Trapped in an anti-prosthetic point of view, Paul adheres to the ideal of the perfect, natural body and rejects Tleilaxu eyes, the artificial metallic eye implants. He insists on employing his inner consciousness in order to maintain the originality of his body. From a Stieglerian perspective, however, only through the prosthesis can one defines the human as a living being. The human, the living, is characterized by the prosthesis, the nonliving, in that even when one remembers the past in the most simple state one has to depend on technics. Bernard Stiegler’s theory of “cinematic consciousness” cogently points out that man’s operation of memory cinematographic employs the technics of montage, and tertiary memory works as an artificial extended limb for the human mind. Human consciousness, often viewed as the pristine part of man uncontaminated by artificiality, is in fact cinematic consciousness, carrying out a play of special effects in one’s memory by either slowing down, speeding up, or even freezing an image. Evading the prosthetic eyes, thus, Paul has rather unwittingly proved the significance of the prosthesis by employing his oracular consciousness. Pressured by Fremen society, which demands that the blind should be exiled to the desert, Paul is blinded more by the social construct of the normal body than the wound. What Paul fails to see beyond is the ideology that upholds the natural body as an ideal norm that one should follow.
