“If consciousness be a mere epiphenomenon… accompanying, but in no way guiding, certain molecular changes in the brain, we shall of course expect… that consciousness is exclusively linked with the functional disintegration of central nervous elements, and varies in its intensity with the rapidity or energy of that disintegration. And ordinary experience, at least within physiological limits, will support some view like this. Yet now and then we find a case where vivid consciousness has existed during a state of apparent coma… tranquilly and intelligently co-existing with an almost complete abeyance of ordinary vital function…. Until this new field has been more fully worked — until the traces of memory which may survive from comatose, ecstatic, syncopal conditions have been revived (by hypnotic suggestion or otherwise), and carefully compared, we have no right to make any absolute assertion as to the concomitant cerebral processes on which consciousness depends.” (Myers, 1891d, 116-117)
