juridical　possession　（possessio　noumenon）。　It　is　founded　upon　the　fact
  that；　as　all　these　acts　are　juridical；　they　consequently　proceed
  from　the　practical　reason；　and　therefore；　in　the　question　as　to　what
  is　right；　abstraction　may　be　made　of　the　empirical　conditions
  involved；　and　the　conclusion；　〃the　external　object　is　mine；〃　thus
  becomes　a　correct　inference　from　the　external　fact　of　sensible
  possession　to　the　internal　right　of　rational　possession。
  The　original　primary　acquisition　of　an　external　object　of　the　action
  of　the　will；　is　called　occupancy。　It　can　only　take　place　in
  reference　to　substances　or　corporeal　things。　Now　when　this
  occupation　of　an　external　object　does　take　place；　the　act　presupposes；
  as　a　condition　of　such　empirical　possession；　its　priority　in　time
  before　the　act　of　any　other　who　may　also　be　willing　to　enter　upon
  occupation　of　it。　Hence　the　legal　maxim：　〃qui　prior　tempore；　potior
  jure。〃　Such　occupation　as　original　or　primary　is；　further；　the
  effect　only　of　a　single　or　unilateral　will；　for　were　a　bilateral　or
  twofold　will　requisite　for　it；　it　would　be　derived　from　a　contract
  of　two　or　more　persons　with　each　other；　and　consequently　it　would　be
  based　upon　what　another　or　others　had　already　made　their　own。　It　is
  not　easy　to　see　how　such　an　act　of　free…will　as　this　would　be　could
  really　form　a　foundation　for　every　one　having　his　own。　However；　the
  first　acquisition　of　a　thing　is　on　that　account　not　quite　exactly
  the　same　as　the　original　acquisition　of　it。　For　the　acquisition　of　a
  public　juridical　state　by　union　of　the　wills　of　all　in　a　universal
  legislation　would　be　such　an　original　acquisition；　seeing　that　no
  other　of　the　kind　could　precede　it；　and　yet　it　would　be　derived　from
  the　particular　wills　of　all　the　individuals；　and　consequently　become
  all…sided　or　omnilateral；　for　a　properly　primary　acquisition　can
  only　proceed　from　an　individual　or　unilateral　or　unilateral　will。
  DIVISION　OF　THE　SUBJECT　OF　THE　ACQUISITION　OF　THE　EXTERNAL
  MINE　AND　THINE。
  I。　In　respect　of　the　matter　of　object　of　acquisition；　I　acquire
  either　a　corporeal　thing　（substance）；　or　the　performance　of
  something　by　another　（causality）；　or　this　other　as　a　person　in　respect
  of　his　state；　so　far　as　I　have　a　right　to　dispose　of　the　same　（in　a
  relation　of　reciprocity　with　him）。
  II。　In　respect　of　the　form　or　mode　of　acquisition；　it　is　either　a
  real　right　（jus　reale）；　or　a　personal　right　（jus　personale）；　or　a
  real…personal　right　（jus　realiter　personale）；　to　the　possession
  although　not　to　the　use；　of　another　person　as　if　he　were　a　thing。
  III。　In　respect　of　the　ground　of　right　or　the　title　（titulus）　of
  acquisition…　which；　properly；　is　not　a　particular　member　of　the
  division　of　rights；　but　rather　a　constituent　element　of　the　mode　of
  exercising　them…　anything　external　is　acquired　by　a　certain　free
  exercise　of　will　that　is　either　unilateral；　as　the　act　of　a　single
  will　（facto）；　or　bilateral；　as　the　act　of　two　wills　（pacto）；　or
  omnilateral；　as　the　act　of　all　the　wills　of　a　community　together
  （lege）。
  SECTION　I。　Principles　of　Real　Right。
  11。　What　is　a　Real　Right？
  The　usual　definition　of　real　right；　or　〃right　in　a　thing〃　（jus
  reale；　jus　in　re）；　is　that　〃it　is　a　right　as　against　every　possessor
  of　it。〃　This　is　a　correct　nominal　definition。　But　what　is　it　that
  entitles　me　to　claim　an　external　object　from　any　one　who　may　appear　as
  its　possessor；　and　to　compel　him；　per　vindicationem；　to　put　me
  again；　in　place　of　himself；　into　possession　of　it？　Is　this　external
  juridical　relation　of　my　will　a　kind　of　immediate　relation　to　an
  external　thing？　If　so；　whoever　might　think　of　his　right　as　referring
  not　immediately　to　persons　but　to　things　would　have　to　represent　it；
  although　only　in　an　obscure　way；　somewhat　thus。　A　right　on　one　side
  has　always　a　duty　corresponding　to　it　on　the　other；　so　that　an
  external　thing；　although　away　from　the　hands　of　its　first　possessor；
  continues　to　be　still　connected　with　him　by　a　continuing　obligation；
  and　thus　it　refuses　to　fall　under　the　claim　of　any　other　possessor；
  because　it　is　already　bound　to　another。　In　this　way　my　right；　viewed
  as　a　kind　of　good　genius　accompanying　a　thing　and　preserving　it　from
  all　external　attack；　would　refer　an　alien　possessor　always　to　me！　It
  is；　however；　absurd　to　think　of　an　obligation　of　persons　towards
  things；　and　conversely；　although　it　may　be　allowed　in　any　particular
  case　to　represent　the　juridical　relation　by　a　sensible　image　of　this
  kind；　and　to　express　it　in　this　way。
  The　real　definition　would　run　thus：　〃Right　in　a　thing　is　a　right
  to　the　private　use　of　a　thing；　of　which　I　am　in　possession…　original
  or　derivative…　in　common　with　all　others。〃　For　this　is　the　one
  condition　under　which　it　is　alone　possible　that　I　can　exclude　every
  others　possessor　from　the　private　use　of　the　thing　（jus　contra
  quemlibet　hujus　rei　possessorem）。　For；　except　by　presupposing　such　a
  common　collective　possession；　it　cannot　be　conceived　how；　when　I　am
  not　in　actual　possession　of　a　thing；　I　could　be　injured　or　wronged
  by　others　who　are　in　possession　of　it　and　use　it。　By　an　individual　act
  of　my　own　will　I　cannot　oblige　any　other　person　to　abstain　from　the
  use　of　a　thing　in　respect　of　which　he　would　otherwise　be　under　no
  obligation；　and；　accordingly；　such　an　obligation　can　only　arise　from
  the　collective　will　of　all　united　in　a　relation　of　common
  possession。　Otherwise；　I　would　have　to　think　of　a　right　in　a　thing；　as
  if　the　thing　has　an　obligation　towards　me；　and　as　if　the　right　as
  against　every　possessor　of　it　had　to　be　derived　from　this　obligation
  in　the　thing；　which　is　an　absurd　way　of　representing　the　subject。
  Further；　by　the　term　real　right　（jus　reale）　is　meant　not　only　the
  right　in　a　thing　（jus　in　re）；　but　also　the　constitutive　principle　of
  all　the　laws　which　relate　to　the　real　mine　and　thine。　It　is；
  however；　evident　that　a　man　entirely　alone　upon　the　earth　could
  properly　neither　have　nor　acquire　any　external　thing　as　his　own；
  because；　between　him　as　a　person　and　all　external　things　as　material
  objects；　there　could　be　no　relations　of　obligation。　There　is
  therefore；　literally；　no　direct　right　in　a　thing；　but　only　that
  right　is　to　be　properly　called　〃real〃　which　belongs　to　any　one　as
  constituted　against　a　person；　who　is　in　common　possession　of　things
  with　all　others　in　the　civil　state　of　society。
  12。　The　First　Acquisition　of　a　Thing　can　only
  be　that　of　the　Soil。
  By　the　soil　is　understood　all　habitable　Land。　In　relation　to
  everything　that　is　moveable　upon　it；　it　is　to　be　regarded　as　a
  substance；　and　the　mode　of　the　existence　of　the　moveables　is　viewed　as
  an　inherence　in　it。　And　just　as；　in　the　theoretical　acceptance；
  accidents　cannot　exist　apart　from　their　substances；　so；　in　the
  practical　relation；　moveables　upon　the　soil　cannot　be　regarded　as
  belonging　to　any　one　unless　he　is　supposed　to　have　been　previously
  in　juridical　possession　of　the　soil；　so　that　it　is　thus　considered
  to　be　his。
  For；　let　it　be　supposed　that　the　soil　belongs　to　no　one。　Then　I
  would　be　entitled　to　remove　every　moveable　thing　found　upon　it　from
  its　place；　even　to　total　loss　of　it；　in　order　to　occupy　that　place；
  without　infringing　thereby　on　the　freedom　of　any　other；　there　being；
  by　the　hypothesis；　no　possessor　of　it　at　all。　But　everything　that
  can　be　destroyed；　such　as　a　tree；　a　house；　and　such　like…　as　regards
  its　matter　at　least…　is　moveable；　and　if　we　call　a　thing　which
  cannot　be　moved　without　destruction　of　its　form　an　immoveable；　the
  mine　and　thine　in　it　is　not　understood　as　applying　to　its　substance；
  but　to　that　which　is　adherent　to　it　and　which　does　not　essentially
  constitute　the　thing　itself。
  13。　Every　Part　of　the　Soil　may　be　Originally　Acquired；　and
  the　Principle　of　the　Possibility　of　such　Acquisition
  is　the　Original　Community　of　the　Soil　Generally。
  The　first　clause　of　this　proposition　is　founded　upon　the　postulate
  of　the　practical　reason　（SS　2）；　the　second　is　established　by　the
  following　proof。
  All　men　are　originally　and　before　any　juridical　act　of　will　in
  rightful　possession　of　the　soil；　that　is；　they　have　a　right　to　be
  wherever　nature　or　chance　has　placed　them　without　their　will。
  Possession　（possessio）；　which　is　to　be　distinguished　from
  residential　settlement　（sedes）　as　a　voluntary；　acquired；　and　permanent
  possession；　becomes　common　possession；　on　account　of　the　connection
  with　each　other　of　all　the　places　on　the　surface　of　the　earth　as　a
  globe。　For；　had　the　surface　of　the　earth　been　an　infinite　plain；　men
  could　have　been　so　dispersed　upon　it　that　they　might　not　have　come
  into　any　necessary　communion　with　each　other；　and　a　state　of　social
  community　would　not　have　been　a　necessary　consequence　of　their
  existence　upon　the　earth。　Now　that　possession　proper　to　all　men　upon
  the　earth；　which　is　prior
