Phantom Signs – Hidden (Bio)Semiosis in the Human Body(?)

The visible human body is composed of flesh and bones for the most part, yet an invisible orchestra of sensations and perceptions creates a virtual or phantom body that behaves like a shadow following every movement and gesture of its anatomical complement. This shadow becomes only “visible” to the individual when bodily integrity is affected, anatomically or cognitively. Phantom limbs have been known for a long time. They refer to the felt presence of a missing hand, leg, or other body part as if it was still in place. Reciprocally and of a supposedly cognitive origin, phantom extremities are reported by some patients that feel the virtual presence of a supernumerary limb – signifying anatomical “overcompleteness.” However, other patients feel as one of their limbs does not belong to their body – signifying “foreignness”. Various shades of the so-called body integrity identity disorder exemplify the assumed complex signification processes within the human body. The Peircean theory of signs and the Uexküllian concept of endosemiosis are combined to approach the still poorly understood phantom phenomena in light of representation and embodiment.
