Externalization
Externalization
(Lat. externus, external from exter, without) The mental act by which sensory data originally considered to be internal arc projected into the external world. See Introjection. The problem of externalization was formulated by Condillac in these words”If one admits that sensations are only modifications of the mind, how does it come about that the mind apprehends them as objects independent of and external to it.” Traite de sensations, Part III. — L.W.
