title: Epilepsy and recursive consciousness with special attention to Jackson's theory of consciousness.
abstract: John Hughlings Jackson's theory of consciousness has been reconsidered. The author stressed that his uniqueness as a neuroscientist lay in his keen interest in the recursive nature of human consciousness. Two clinical symptoms of interest to Jackson were discussed: recurrent utterances and mental diplopia. Recurrent utterances were believed to represent an exceptional state, in which the unconscious process in speech production, otherwise destined to be swept away automatically, became manifest and observable. Jackson regarded mental diplopia as a revelation of otherwise inaccessible duality of all healthy mental actions. Therefore, he supposed that the essence of recursive consciousness resided in a transformation of multiple, multidirectional, unconscious processes into a linear, unidirectional process.
