Marshall McLuhan defines technology as any extension of the human body, an enhancement of some bodily function within the body's environment. But the human body is not a concept within a purely conceptual time/space continuum, or, universe. The human body is inclusive of imagination; the human body is an image and a concept. The human body cannot perceive in the absence of imagination. This fact, which is obvious to human experience, is what the body of science denies. Why does the body deceive itself, as to the environment it is within?

Technology is an intrument of human fantasy; its purpose is fantastic. The fantastic goal is to realize the dream, to manufacture a real image. A fantastic goal is always self-contradictory, impossible of fulfillment; imagination and conceptuality contradict each other. What concepts do, images undo, and yet in human experience the two are inseparable, not unlike life and death.

Once the thinker abandons the abstraction of the "reality principle" the efficacy of the scientific method in its application to the human body begins to slip away. The principles of reality are not the exclusive rules of the game. In human experience, the real is always infected with the unreal. The body and it's environment are fantastic; the method is necessarily symbolic.
