water…animals
  hunting；　or　the　hunting　after　animals　who　swim？
  Theaet。　True。
  Str。　And　of　swimming　animals；　one　class　lives　on　the　wing　and　the
  other　in　the　water？
  Theaet。　Certainly。
  Str。　Fowling　is　the　general　term　under　which　the　hunting　of　all
  birds　is　included。
  Theaet。　True。
  Str。　The　hunting　of　animals　who　live　in　the　water　has　the　general
  name　of　fishing。
  Theaet。　Yes。
  Str。　And　this　sort　of　hunting　may　be　further　divided　also　into　two
  principal　kinds？
  Theaet。　What　are　they？
  Str。　There　is　one　kind　which　takes　them　in　nets；　another
  which　takes
  them　by　a　blow。
  Theaet。　What　do　you　mean；　and　how　do　you　distinguish　them？
  Str。　As　to　the　first　kind…all　that　surrounds　and　encloses　anything
  to　prevent　egress；　may　be　rightly　called　an　enclosure。
  Theaet。　Very　true。
  Str。　For　which　reason　twig　baskets；　casting　nets；　nooses；　creels；
  and　the　like　may　all　be　termed　〃enclosures〃？
  Theaet。　True。
  Str。　And　therefore　this　first　kind　of　capture　may　be　called　by　us
  capture　with　enclosures；　or　something　of　that　sort？
  Theaet。　Yes。
  Str。　The　other　kind；　which　is　practised　by　a　blow　with　hooks　and
  three　pronged　spears；　when　summed　up　under　one　name；　may　be　called
  striking；　unless　you；　Theaetetus；　can　find　some　better　name？
  Theaet。　Never　mind　the　name…what　you　suggest　will　do　very　well。
  Str。　There　is　one　mode　of　striking；　which　is　done　at　night；　and　by
  the　light　of　a　fire；　and　is　by　the　hunters　themselves　called　firing；
  or　spearing　by　firelight。
  Theaet。　True。
  Str。　And　the　fishing　by　day　is　called　by　the　general　name
  of　barbing
  because　the　spears；　too；　are　barbed　at　the　point。
  Theaet。　Yes；　that　is　the　term。
  Str。　Of　this　barb…fishing；　that　which　strikes　the　fish　Who　is
  below　from　above　is　called　spearing；　because　this　is　the　way　in
  which　the　three…pronged　spears　are　mostly　used。
  Theaet。　Yes；　it　is　often　called　so。
  Str。　Then　now　there　is　only　one　kind　remaining。
  Theaet。　What　is　that？
  Str。　When　a　hook　is　used；　and　the　fish　is　not　struck　in　any　chance
  part　of　his　body…he　as　be　is　with　the　spear；　but　only　about　the　head
  and　mouth；　and　is　then　drawn　out　from　below　upwards　with　reeds　and
  rods：…What　is　the　right　name　of　that　mode　of　fish；　Theaetetus？
  Theaet。　I　suspect　that　we　have　now　discovered　the　object　of　our
  search。
  Str。　Then　now　you　and　I　have　come　to　an　understanding　not
  only　about
  the　name　of　the　angler's　art；　but　about　the　definition　of　the　thing
  itself。　One　half　of　all　art　was　acquisitive…half　of　all　the　art
  acquisitive　art　was　conquest　or　taking　by　force；　half　of　this　was
  hunting；　and　half　of　hunting　was　hunting　animals；　half　of　this　was
  hunting　water　animals…of　this　again；　the　under　half　was　fishing；
  half　of　fishing　was　striking；　a　part　of　striking　was　fishing　with　a
  barb；　and　one　half　of　this　again；　being　the　kind　which　strikes　with
  a　hook　and　draws　the　fish　from　below　upwards；　is　the　art
  which　we　have
  been　seeking；　and　which　from　the　nature　of　the　operation　is　denoted
  angling　or　drawing　up　（aspalienutike；　anaspasthai）。
  Theaet。　The　result　has　been　quite　satisfactorily　brought　out。
  Str。　And　now；　following　this　pattern；　let　us　endeavour　to　find　out
  what　a　Sophist　is。
  Theaet。　By　all　means。
  Str。　The　first　question　about　the　angler　was；　whether　he　was　a
  skilled　artist　or　unskilled？
  Theaet。　True。
  Str。　And　shall　we　call　our　new　friend　unskilled；　or　a　thorough
  master　of　his　craft？
  Theaet。　Certainly　not　unskilled；　for　his　name；　as；　indeed；　you
  imply；　must　surely　express　his　nature。
  Str。　Then　he　must　be　supposed　to　have　some　art。
  Theaet。　What　art？
  Str。　By　heaven；　they　are　cousins！　it　never　occurred　to　us。
  Theaet。　Who　are　cousins？
  Str。　The　angler　and　the　Sophist。
  Theaet。　In　what　way　are　they　related？
  Str。　They　both　appear　to　me　to　be　hunters。
  Theaet。　How　the　Sophist？　Of　the　other　we　have　spoken。
  Str。　You　remember　our　division　of　hunting；　into　hunting　after
  swimming　animals　and　land　animals？
  Theaet。　Yes。
  Str。　And　you　remember　that　we　subdivided　the　swimming　and　left　the
  land　animals；　saying　that　there　were　many　kinds　of　them？
  Theaet。　Certainly。
  Str。　Thus　far；　then；　the　Sophist　and　the　angler；　starting　from　the
  art　of　acquiring；　take　the　same　road？
  Theaet。　So　it　would　appear。
  Str。　Their　paths　diverge　when　they　reach　the　art　of　animal
  hunting；　the　one　going　to　the　seashore；　and　to　the　rivers　and　to　the
  lakes；　and　angling　for　the　animals　which　are　in　them。
  Theaet。　Very　true。
  Str。　While　the　other　goes　to　land　and　water　of　another　sort…rivers
  of　wealth　and　broad　meadow…lands　of　generous　youth；　and　he　also　is
  intending　to　take　the　animals　which　are　in　them。
  Theaet。　What　do　you　mean？
  Str。　Of　hunting　on　land　there　are　two　principal　divisions。
  Theaet。　What　are　they？
  Str。　One　is　the　hunting　of　tame；　and　the　other　of　wild　animals。
  Theaet。　But　are　tame　animals　ever　hunted？
  Str。　Yes；　if　you　include　man　under　tame　animals。　But　if
  you　like　you
  may　say　that　there　are　no　tame　animals；　or　that；　if　there　are；　man
  is　not　among　them；　or　you　may　say　that　man　is　a　tame　animal
  but　is　not
  hunted…you　shall　decide　which　of　these　alternatives　you　prefer。
  Theaet。　I　should　say；　Stranger；　that　man　is　a　tame　animal；　and　I
  admit　that　he　is　hunted。
  Str。　Then　let　us　divide　the　hunting　of　tame　animals　into　two　parts。
  Theaet。　How　shall　we　make　the　division？
  Str。　Let　us　define　piracy；　man…stealing；　tyranny；　the
  whole　military
  art；　by　one　name；　as　hunting　with　violence。
  Theaet。　Very　good。
  Str。　But　the　art　of　the　lawyer；　of　the　popular　orator；　and　the　art
  of　conversation　may　be　called　in　one　word　the　art　of　persuasion。
  Theaet。　True。
  Str。　And　of　persuasion；　there　may　be　said　to　be　two　kinds？
  Theaet。　What　are　they？
  Str。　One　is　private；　and　the　other　public。
  Theaet。　Yes；　each　of　them　forms　a　class。
  Str。　And　of　private　hunting；　one　sort　receives　hire；　and　the　other
  brings　gifts。
  Theaet。　I　do　not　understand　you。
  Str。　You　seem　never　to　have　observed　the　manner　in　which　lovers
  hunt。
  Theaet。　To　what　do　you　refer？
  Str。　I　mean　that　they　lavish　gifts　on　those　whom　they　hunt　in
  addition　to　other　inducements。
  Theaet。　Most　true。
  Str。　Let　us　admit　this；　then；　to　be　the　amatory　art。
  Theaet。　Certainly。
  Str。　But　that　sort　of　hireling　whose　conversation　is　pleasing　and
  who　baits　his　hook　only　with　pleasure　and　exacts　nothing　but　his
  maintenance　in　return；　we　should　all；　if　I　am　not　mistaken；　describe
  as　possessing　flattery　or　an　art　of　making　things　pleasant。
  Theaet。　Certainly。
  Str。　And　that　sort；　which　professes　to　form　acquaintances　only　for
  the　sake　of　virtue；　and　demands　a　reward　in　the　shape　of
  money；　may　be
  fairly　called　by　another　name？
  Theaet。　To　be　sure。
  Str。　And　what　is　the　name？　Will　you　tell　me？
  Theaet。　It　is　obvious　enough；　for　I　believe　that　we　have
  discovered　the　Sophist：　which　is；　as　I　conceive；　the　proper　name　for
  the　class　described。
  Str。　Then　now；　Theaetetus；　his　art　may　be　traced　as　a　branch　of
  the　appropriative；　acquisitive　family…which　hunts
  animals；…living…land…tame　animals；　which　hunts　man；…privately…for
  hire；…taking　money　in　exchange…having　the　semblance　of　education；
  and　this　is　termed　Sophistry；　and　is　a　hunt　after　young　men　of
  wealth　and　rank…such　is　the　conclusion。
  Theaet。　Just　so。
  Str。　Let　us　take　another　branch　of　his　genealogy；　for　he　is　a
  professor　of　a　great　and　many　sided　art；　and　if　we　look　back　at　what
  has　preceded　we　see　that　he　presents　another　aspect；　besides　that　of
  which　we　are　speaking。
  Theaet。　In　what　respect？
  Str。　There　were　two　sorts　of　acquisitive　art；　the　one
  concerned　with
  hunting；　the　other　with　exchange。
  Theaet。　There　were。
  Str。　And　of　the　art　of　exchange　there　are　two　divisions；　the　one
  of　giving；　and　the　other　of　selling。
  Theaet。　Let　us　assume　that。
  Str。　Next；　will　suppose　the　art　of　selling　to　be　divided　into　two
  parts。
  Theaet。　How？
  Str。　There　is　one　part　which　is　distinguished　as　the　sale
  of　a　man's
  own　productions；　another；　which　is　the　exchange　of　the　works　of
  others。
  Theaet。　Certainly。
  Str。　And　is　not　that　part　of　exchange　which　takes　place　in
  the　city；
  being　about　half　of　the　whole；　termed　retailing？
  Theaet。　Yes。
  Str。　And　that　which　exchanges　the　goods　of　one　city　for　those　of
  another　by　selling　and　buying　is　the　exchange　of　the　merchant？
  Theaet。　To　be　sure。
  Str。　And　you　are　aware　that　this　exchange　of　the　merchant　is　of
  two　kinds：　it　is　partly　concerned　with　food　for　the　use　of　the　body；
  and　partly　with　the　food　of　the　soul　which　is　bartered　and
  received　in
  exchange　for　money。
  Theaet。　What　do　you　mean？
  Str。　You　want　to　know　what　is　the　meaning　of　food　for　the　soul；
  the　other　kind　you　surely　understand。
  Theaet。　Yes。
  Str。　Take　music　in　general　and　painting　and　marionette　playing　and
  many　other　things；　which　are　purchased　in　one　city；　and　carried　away
  and　sold　in　another…wares　of　the　soul　which　are　hawked　about　either
  for　the　sake　of　instruction　or　amusement；…may　not　he
