  THEROMANS
  Notwithstandingtheeminentlypractical,realistic,andutilitariancharacteroftheRomans,therewasnoenergeticexerciseof
  theirpowersintheeconomicfield;theydevelopednolargeandmany—sidedsystemofproductionandexchange。Their
  historicmissionwasmilitaryandpolitical,andthenationalenergiesweremainlydevotedtothepublicserviceathomeand
  inthefield。Toagriculture,indeed,muchattentionwasgivenfromtheearliesttimes,andonitwasfoundedtheexistenceof
  thehardypopulationwhichwonthefirststepsinthemarchtouniversaldominion。Butinthecourseoftheirhistorythe
  cultivationofthesoilbyanativeyeomanrygaveplacetotheintroduction,ingreatnumbers,ofslavelabourersacquiredby
  theirforeignconquests;andforthesmallpropertiesoftheearlierperiodweresubstitutedthevastestates——thelatifundia——
  which,inthejudgmentofPliny,weretheruinofItaly。(1)Theindustrialartsandcommerce(thelatter,atleastwhennot
  conductedonagreatscale)theyregardedasignoblepursuits,unworthyoffreecitizens;andthisfeelingofcontemptwas
  notmerelyaprejudiceofnarroworuninstructedminds,butwassharedbyCiceroandothersamongthemostliberalspirits
  ofthenation。(2)AsmightbeexpectedfromthewantofspeculativeoriginalityamongtheRomans,thereislittleevidenceof
  serioustheoreticinquiryoneconomicsubjects。Theirideasontheseasonothersocialquestionswereforthemostpart
  borrowedfromtheGreekthinkers。Suchtracesofeconomicthoughtasdooccuraretobefoundin(1)thephilosophers,(2)
  thewritersdererustica,and(3)thejurists。Itmust,however,beadmittedthatmanyofthepassagesintheseauthors
  referredtobythosewhoasserttheclaimoftheRomanstoamoreprominentplaceinthehistoryofthescienceoftencontain
  onlyobvioustruthsorvaguegeneralities。
  Inthephilosophers,whomCicero,Seneca,andtheelderPlinysufficientlyrepresent(thelastindeedbeingratheralearned
  encyclopaedistorpolyhistorthanaphilosopher),wefindageneralconsciousnessofthedecayofindustry,therelaxationof
  morals,andthegrowingspiritofself—indulgenceamongsttheircontemporaries,whoarerepresentedasdeeplytaintedwith
  theimportedvicesoftheconquerednations。Thissentiment,bothinthesewritersandinthepoetryandmiscellaneous
  literatureoftheirtimes,isaccompaniedbyahalf—factitiousenthusiasmforagricultureandanexaggeratedestimateof
  countrylifeandofearlyRomanhabits,whichareprincipally,nodoubt,toberegardedasaformofprotestagainstexisting
  abuses,and,fromthispointofview,remindusofthedeclamationsofRousseauinanotdissimilarage。Butthereislittleof
  largerorjustthinkingontheprevalenteconomicevilsandtheirproperremedies。Pliny,stillfurtherinthespiritofRousseau,
  isofopinionthattheintroductionofgoldasamediumofexchangewasathingtobedeplored,andthattheageofbarter
  waspreferabletothatofmoney。Heexpressesviewsonthenecessityofpreventingtheeffluxofmoneysimilartothoseof
  themodernmercantileschool——viewswhichCiceroalso,thoughnotsoclearly,appearstohaveentertained。Cato,Varro,
  andColumellaconcernthemselvesmorewiththetechnicalpreceptsofhusbandrythanwiththegeneralconditionsof
  industrialsuccessandsocialwell—being。Butthetwolastnamedhavethegreatmeritofhavingseenandproclaimedthe
  superiorvalueoffreetoslavelabour,andColumellaisconvincedthattotheuseofthelatterthedeclineoftheagricultural
  economyoftheRomanswasinagreatmeasuretobeattributed。Thesethreewritersagreeinthebeliefthatitwaschieflyby
  therevivalandreformofagriculturethatthethreateninginroadsofmoralcorruptioncouldbestayed,theoldRomanvirtues
  fostered,andthefoundationsofthecommonwealthstrengthened。TheirattitudeisthussimilartothatoftheFrench
  physiocratsinvokingtheimprovementandzealouspursuitofagriculturealikeagainstthematerialevilsandthesocial
  degeneracyoftheirtime。Thequestionofthecomparativemeritsofthelargeandsmallsystemsofcultivationappearsto
  havebeenmuchdiscussedintheoldRoman,asinthemodernEuropeanworld;Columellaisadecidedadvocateofthe
  petiteculture。Thejuristswereledbythecoincidencewhichsometimestakesplacebetweentheirpointofviewandthatof

  matter,however,oughttobeadvertedto,becauseitwasnotonlyrepeatedlydealtwithbylegislation,butistreatedmoreor
  lessfullybyallRomanwritersofnote,namely,theinterestonmoneyloans。TheratewasfixedbythelawsoftheTwelve
  Tables;butlendingoninterestwasafterwards(B。C。341)entirelyprohibitedbytheGenucianLaw,Inthelegislationof
  Justinian,ratesweresanctionedvaryingfromfourtoeightpercentaccordingtothenatureofthecase,thelatterbeingfixed

  disapproveoflendingoninterestaltogether。Cato,asCicerotellsus,thoughtitasbadasmurder("Quidfenerari?Quid
  hominemoccidere?"DeOff,ii。25);andCicero,Seneca,Pliny,Columellaalljoinincondemningit。Itisnotdifficulttosee
