　　`Tisevident，thatprideandhumility，tho’directlycontrary，haveyetthesameOBJECT。Thisobjectisself，orthatsuccessionofrelatedideasandimpressions，ofwhichwehaveanintimatememoryandconsciousness。`Heretheviewalwaysfixeswhenweareactuatedbyeitherofthesepassions。Accordingasourideaofourselfismoreorlessadvantageous，wefeeleitherofthoseoppositeaffections，andareelatedbypride，ordejectedwithhumility。Whateverotherobjectsmaybecomprehendedbythemind，theyarealwaysconsider’dwithaviewtoourselves；otherwisetheywouldneverbeableeithertoexcitethesepassions，orproducethesmallestencreaseordiminutionofthem。Whenselfentersnotintotheconsideration，thereisnoroomeitherforprideorhumility。
　　Buttho’thatconnectedsuccessionofperceptions，whichwecallself，bealwaystheobjectofthesetwopassions，`tisimpossibleitcanbetheirCAUSE，orbesufficientalonetoexcitethem。Forasthesepassionsaredirectlycontrary，andhavethesameobjectincommon；weretheirobjectalsotheircause；itcou’dneverproduceanydegreeoftheonepassion，butatthesametimeitmustexciteanequaldegreeoftheother；whichoppositionandcontrarietymustdestroyboth。Tisimpossibleamancanatthesametimebebothproudandhumble；andwherehehasdifferentreasonsforthesepassions，asfrequentlyhappens，thepassionseithertakeplacealternately；oriftheyencounter，theoneannihilatestheother，asfarasitsstrengthgoes，andtheremainderonlyofthat，whichissuperior，continuestooperateuponthemind。Butinthepresentcaseneitherofthepassionscou’deverbecomesuperior；becausesupposingittobetheviewonlyofourself，whichexcitedthem，thatbeingperfectlyindifferenttoeither，mustproducebothintheverysameproportion；orinotherwords，canproduceneither。Toexciteanypassion，andat’thesametimeraiseanequalshareofitsantagonist，isimmediatelytoundowhatwasdone，andmustleavethemindatlastperfectlycalmandindifferent。
　　Wemusttherefore，makeadistinctionbetwixtthecauseandtheobjectofthesepassions；betwixtthatidea，whichexcitesthem，andthattowhichtheydirecttheirview，whenexcited。Prideandhumility，beingoncerais’d，immediatelyturnourattentiontoourself，andregardthatastheirultimateandfinalobject；butthereissomethingfartherrequisiteinordertoraisethem:Something，whichispeculiartooneofthepassions，andproducesnotbothintheverysamedegree。Thefirstidea，thatispresentedtothemind，isthatofthecauseorproductiveprinciple。Thisexcitesthepassion，connectedwithit；andthatpassion，whenexcited。turnsourviewtoanotheridea，whichisthatofself。Herethenisapassionplac’dbetwixttwoideas，ofwhichtheoneproducesit，andtheotherisproduc’dbyit。Thefirstidea，therefore，representsthecause，thesecondtheobjectofthepassion。
　　Tobeginwiththecausesofprideandhumility；wemayobserve，thattheirmostobviousandremarkablepropertyisthevastvarietyofsubjects，onwhichtheymaybeplac’d。Everyvaluablequalityofthemind，whetheroftheimagination，judgment，memoryordisposition；wit，good-sense，learning，courage，justice，integrity；allthesearethecauseofpride；andtheiroppositesofhumility。Norarethesepassionsconfin’dtothemindbutextendtheirviewtothebodylikewise。Amanmayheproudofhisbeauty，strength，agility，goodmein，addressindancing，riding，andofhisdexterityinanymanualbusinessormanufacture。Butthisisnotall。Thepassionslookingfarther，comprehendwhateverobjectsareintheleastally’dorrelatedtous。Ourcountry，family，children，relations，riches，houses，gardens，horses，dogs，cloaths；anyofthesemaybecomeacauseeitherofprideorofhumility。
　　Fromtheconsiderationofthesecauses，itappearsnecessaryweshoudmakeanewdistinctioninthecausesofthepassion，betwixtthatquality，whichoperates，andthesubject，onwhichitisplac’d。Aman，forinstance，isvainofabeautifulhouse，whichbelongstohim，orwhichhehashimselfbuiltandcontriv’d。Heretheobjectofthepassionishimself，andthecauseisthebeautifulhouse:Whichcauseagainissub-dividedintotwoparts，viz。thequality，whichoperatesuponthepassion，andthesubjectinwhichthequalityinheres。Thequalityisthebeauty，andthesubjectisthehouse，consider’dashispropertyorcontrivance。Boththesepartsareessential，noristhedistinctionvainandchimerical。Beauty，consider’dmerelyassuch，unlessplac’duponsomethingrelatedtous，neverproducesanyprideorvanity；andthestrongest。relationalone，withoutbeauty，orsomethingelseinitsplace，hasaslittleinfluenceonthatpassion。Since，therefore，thesetwoparticularsareeasilyseparatedandthereisanecessityfortheirconjunction，inordertoproducethepassion，weoughttoconsiderthemascomponentpartsofthecause；andinfixinourmindsanexactideaofthisdistinction。

　　Buttho’thecausesofprideandhumilitybeplainlynatural，weshallfinduponexamination，thattheyarenotoriginal，andthat`tisutterlyimpossibletheyshou’deachofthembeadaptedtothesepassionsbyaparticularprovision，andprimaryconstitutionofnature，Besidetheirprodigiousnumber，manyofthemaretheeffectsofart，andarisepartlyfromtheindustry，partlyfromthecaprice，andpartlyfromthegoodfortuneofmen，Industryproduceshouses，furniture，cloaths。Capricedeterminestheirparticularkindsandqualities。Andgoodfortunefrequentlycontributestoallthis，bydiscoveringtheeffectsthatresultfromthedifferentmixturesandcombinationsofbodies。Tisabsurd，therefore，toimagine，thateachofthesewasforeseenandprovidedforbynature，andthateverynewproductionofart，whichcausesprideorhumility；insteadofadaptingitselftothepassionbypartakingofsomegeneralquality，thatnaturallyoperatesonthemind；isitselftheobjectofanoriginalprinciple，whichtillthenlayconceal’dinthesoul，andisonlybyaccidentatlastbroughttolight。Thusthefirstmechanic，thatinventedafinescritoire，produc’dprideinhim，whobecamepossestofit，byprinciplesdifferentfromthose，whichmadehimproudofhandsomechairsandtables。Asthisappearsevidentlyridiculous，wemustconclude，thateachcauseofprideandhumilityisnotadaptedtothepassionsbyadistinctoriginalquality；butthattherearesomeoneormorecircumstancescommontoallofthem，onwhichtheirefficacydepends。
