  Theyquitecorrectlystatedthatthevocationofbourgeoissocietywasthemakingofmoney,andhence,fromthestandpointofsimplecommodityproduction,theformationofpermanenthoardswhichneithermothsnorrustcoulddestroy。ItisnorefutationoftheMonetarySystemtopointoutthatatonofironwhosepriceis£3hasthesamevalueas£3

  Itwasconsistentwiththerudimentarystageofbourgeoisproductionthatthosemisunderstoodprophetsshouldhaveclungtothesolid,palpableandglitteringformofexchange—value,toexchange—valueintheformoftheuniversalcommodityasdistinctfromallparticularcommodities。Thesphereofcommoditycirculationwasthestrictlybourgeoiseconomicsphereatthattime。Theythereforeanalysedthewholecomplexprocessofbourgeoisproductionfromthestandpointofthatbasicsphereandconfusedmoneywithcapital。TheunceasingfightofmoderneconomistsagainsttheMonetaryandMercantilesystemsismainlyprovokedbythefactthatthesecretofbourgeoisproduction,i。e。,thatitisdominatedbyexchange—value,isdivulgedinanaivelybrutalwaybythesesystems。Althoughdrawingthewrongconclusionsfromit,Ricardoobservessomewherethat,evenduringafamine,cornisimportedbecausethecorn—merchanttherebymakesmoney,andnotbecausethenationisstarving。PoliticaleconomyerrsinitscritiqueoftheMonetaryandMercantilesystemswhenitassailsthemasmereillusions,asutterlywrongtheories,andfailstonoticethattheycontaininaprimitiveformitsownbasicpresuppositions。Thesesystems,moreover,remainnotonlyhistoricallyvalidbutretaintheirfullvaliditywithincertainspheresofthemoderneconomy。Ateverystageofthebourgeoisprocessofproductionwhenwealthassumestheelementaryformofcommodities,exchange—valueassumestheelementaryformofmoney,andinallphasesoftheproductiveprocesswealthforaninstantrevertsagaintotheuniversalelementaryformofcommodities。Thefunctionsofgoldandsilverasmoney,incontradistinctiontotheirfunctionsasmeansofcirculationandincontrastwithallothercommodities,arenotabolishedeveninthemostadvancedbourgeoiseconomy,butmerelyrestricted;theMonetaryandMercantilesystemsaccordinglyremainvalid。Thecatholicfactthatgoldandsilverasthedirectembodimentofsociallabour,andthereforeastheexpressionofabstractwealth,confrontotherprofanecommodities,hasofcourseviolatedtheprotestantcodeofhonourofbourgeoiseconomists,andfromfearoftheprejudicesoftheMonetarySystem,theylostforsometimeanysenseofdiscriminationtowardsthephenomenaofmoneycirculation,asthefollowingaccountwillshow。
  Itwasquitenaturalthat,bycontrastwiththeMonetaryandMercantilesystems,whichknewmoneyonlyasacrystallineproductofcirculation,classicalpoliticaleconomyinthefirstinstanceshouldhaveunderstoodthefluidformofmoney,thatistheformofexchange—valuewhicharisesandvanisheswithinthemetamorphosisofcommodities。BecausecommoditycirculationislookedatexclusivelyintheformC——M——C,andthisinitsturnsolelyasthedynamicunityofsaleandpurchase,thespecificaspectofmoneyasmeansofcirculationisupheldagainstitsspecificaspectasmoney。Ifthefunctionofmeansofcirculationinservingascoinisisolated,then,aswehaveseen,itbecomesavalue—token。Butsinceclassicalpoliticaleconomywasatfirstconfrontedwithmetalliccurrencyasthepredominantformofcurrency,itregardedmetallicmoneyascoin,andcoinasameretokenofvalue。Inaccordancewiththelawrelatingtothecirculationofvalue—tokens,thepropositionisthenadvancedthatthepricesofcommoditiesdependonthevolumeofmoneyincirculation,andnotthatthevolumeofmoneyincirculationdependsonthepricesofcommodities。ThisviewismoreorlessclearlyoutlinedbyItalianeconomistsoftheseventeenthcentury;itissometimesaccepted,sometimesrepudiatedbyLocke,andfirmlysetforthintheSpectator(intheissueofOctober19,1711)aswellasintheworksofMontesquieuandHume。SinceHumeisbyfarthemostimportantexponentofthistheoryintheeighteenthcentury,weshallbeginoursurveywithhim。
  Undercertainconditions,anincreaseordecreaseinthequantityofeitherspecieincirculation,ortokensofvalueincirculation,seemstohaveasimilareffectuponcommodity—prices。Ifthereisafallorriseinthevalueofgoldandsilver,inwhichtheexchange—valueofcommoditiesismeasuredasprice,thenpricesriseorfallbecauseachangehastakenplaceintheirstandardofvalue;andanincreasedordiminishedamountofgoldandsilverisincirculationascoinbecausethepriceshaverisenorfallen。Theobservablephenomenon,however,isthatwithanincreasingordiminishingvolumeofmeansofcirculation,priceschangewhiletheexchange—valueofcommoditiesremainsconstant。
  If,ontheotherhand,theamountofvalue—tokensincirculationfallsbelowtherequisitelevel,orrisesaboveit,thenitisforciblyreducedtothatlevelbyafallorriseofcommodity—prices。Theeffectinbothcasesappearstobebroughtaboutbythesamecause,andHumeholdsfasttothisappearance。
  Anyscholarlyinvestigationoftherelationbetweenthevolumeofmeansofcirculationandmovementsincommodity—pricesmustassumethatthevalueofthemonetarymaterialisgiven。Hume,however,considersexclusivelyperiodswhenrevolutionarychangesinthevalueofthepreciousmetalstakeplace,thatisrevolutionsinthestandardofvalue。Theriseincommodity—pricesthatoccurredsimultaneouslywiththeincreaseintheamountofspecieconsequentuponthediscoveryoftheAmericanminesformsthehistoricalbackgroundofhistheory,anditspracticalmotivewasthepolemicthathewagedagainsttheMonetaryandMercantilesystems。Itis,ofcourse,quitepossibletoincreasethesupplyofpreciousmetalswhiletheircostsofproductionremainunchanged。Ontheotherhand,adecreaseintheirvalue,thatisinthelabour—timerequiredtoproducethem,willinthefirstplacebeattestedonlybyanincreaseintheirsupply。Hume'sdisciplesaccordinglystatedsubsequentlythatthediminishedvalueofthepreciousmetalswasreflectedinthegrowingvolumeofmeansofcirculation,andthegrowingvolumeofthemeansofcirculationwasreflectedinincreasedcommodity—prices。Butthereisinrealityanincreaseonlyinthepricesofexportedcommoditieswhichareexchangedforgoldandsilverascommoditiesandnotasmeansofcirculation。Thepriceofthosecommodities,whicharemeasureingoldandsilverofreducedvalue,thusrisesinrelationtoallothercommoditieswhoseexchange—valuecontinuestobemeasuredingoldandsilverinaccordancewiththescaleoftheirformercostsofproduction。Suchadualevaluationofexchange—valuesofcommoditiesinagivencountrycanofcourseoccuronlytemporarily;goldandsilverpricesmustbeadjustedtocorrespondwiththeexchange—valuesthemselves,sothatfinallytheexchange—valuesofallcommoditiesareassessedinaccordancewiththenewvalueofmonetarymaterial。Thisisnottheplaceforeitheradescriptionofthisprocessoranexaminationofthewaysinwhichtheexchange—valueofcommoditiesprevailswithinthefluctuationsofmarket—prices。Recentcriticalinvestigationsofthemovementofcommodity—pricesduringthesixteenthcenturyhaveconclusivelydemonstratedthatintheearlystagesoftheevolutionofthebourgeoismodeofproduction,suchadjustmentproceedsonlyverygradually,extendingoverlongperiods,anddoesnotbyanymeanskeepinstepwiththeincreaseofreadymoneyincirculation。[1]Quiteinappropriatearereferences——invogueamongHume'sdisciples——
