  CHAPTER　V。　THE　UNKNOWN　GUEST

  We　have　now　studied　certain　manifestations　of　that　which　we　have　called　in　turn　and　more　or　less　indiscriminately　the　subconscious　mind；　the　subliminal　consciousness　and　the　unknown　guest；　names　to　which　we　might　add　that　of　the　superior　subconsciousness　or　superior　psychism　invented　by　Dr。　Geley。　Granting　that　these　manifestations　are　really　proved；　it　is　no　longer　possible　to　explain　them　or　rather　to　classify　them　without　having　recourse　to　fresh　theories。　Now　we　can　entertain　doubts　on　many　points；　we　can　cavil　and　argue；　but　I　defy　anyone　approaching　these　facts　in　a　serious　and　honest　spirit　to　reject　them　all。　It　is　permissible　to　neglect　the　most　extraordinary；　but　there　are　a　multitude　of　others　which　have　become　or；　to　speak　more　accurately；　are　acknowledged　to　be　as　frequent　and　habitual　as　any　fact　whatever　in　normal；　everyday　life。　It　is　not　difficult　to　reproduce　them　at　will；　provided　we　place　ourselves　in　the　condition　demanded　by　their　very　nature；　and；　this　being　so；　there　remains　no　valid　reason　for　excluding　them　from　the　domain　of　science　in　the　strict　sense　of　the　word。
  Hitherto；　all　that　we　have　learnt　regarding　these　occurrences　is　that　their　origin　is　unknown。　It　will　be　said　that　this　is　not　much　and　that　the　discovery　is　nothing　to　boast　of。　I　quite　agree：　to　imagine　that　one　can　explain　a　phenomena　by　saying　that　it　is　produced　by　an　unknown　agency　would　indeed　be　childish。　But　it　is　already　something　to　have　marked　its　source；　not　to　be　still　lingering　in　the　thick　of　a　fog；　trying　any　and　every　direction　in　order　to　find　a　way　out；　but　to　be　concentrating　our　attention　on　a　single　spot　which　is　the　starting…point　of　all　these　wonders；　so　that　at　each　instant　we　recognize　in　each　phenomenon　the　characteristic　customs；　methods　or　features　of　the　same　unknown　agency。　It　is　very　nearly　all　that　we　can　do　for　the　moment；　but　this　first　effort　is　not　wholly　to　be　despised。
