A Philosophical Review of the Limitations of Brain-computer Interface Replacing the Body
The emergence of brain-computer interface(BCI)provides the possibility of replacing the body,yet there are currently few philosophical investigations on its replacement"limits".Firstly,current BCI mainly involves the substitution of the perception and agency of the"natural body",but BCI lacks the"precision"of bodily perception and the"smoothness"of body movements,so this substitution is limited.Secondly,phenomenology of the body regards the body as a key concept revealing the existential condition of the subject.This"generalized body view"grasps the cognitive characteristics of the body,which BCI overlooks,resulting in the limitation of substitution.Lastly,the limits of substitution in perception,cognition,and agency determine that they are not"imitations"or"replication"of human and bodily activities,which provide new insights for the future development of BCI.
