　　ThenamesofLocke，Hobbes，Mandeville，andHume，areassociatedwiththeformerschool；thoseofClarke，Price，LordShaftesbury，BishopButler，andHutcheson，withthelatter；andthedifferencebetweenthemisgenerallyex-pressedbyclassingtheformertogetherastheUtilitarian，Selfish，orScepticalSchool，andthelatterastheschoolofIntuitionalists。
　　ThedoctrineofHobbes，thatmoralitywasidenticalwiththepositivecommandsandprohibitionsofthelawgiver，andthatthelawwasthustherealultimatesourceandstandardofallrightandwrong，gaverisetoseveralsystemswhichsoughtindifferentwaystofindforourmoralsentimentsalessvariableandunstablefoundationthanwasimpliedbysuchanhypothesis。
　　ItwasinoppositiontosuchatheorythatClarkeandPrice，andotheradvocatesoftheso-calledRationalorIntellectualsystem，attributedourperceptionofmoraldistinctionstointuitionsofourintellect，sothatthetruthsofmoralitymightappear，likethoseofmathematics，eternalandimmutable，independentofpeculiaritiesoftimeandplace，andwithanexistenceapartfromanyparticularmanorcountry，justasthedefinitionsofgeometryareindependentofanyparticularstraightlinesortriangles。

　　ButthesamefoundationforanimmutablemoralitythatClarkesoughtforinthehumanintellect，otherssoughtforinapeculiarinstinctofournature。ThusLordShaftesburypostulatedtheexistenceofamoralsense，sufficientofitselftomakeuseschewviceandfollowaftervirtue；andthismoralsense，orprimitiveinstinctforgood，wasimplantedinusbynature，andcarrieditsownauthoritywithit。Itjudgedofactionsbyreferencetoacertainharmonybetweenouraffections，andthisharmonyhadarealexistence，independentof'allfashionandcaprice，likeharmonyinmusic。Assymmetryandproportionwerefoundedinnature，howsoeverbarbarousmightbemen'stastesinthearts，so，inmorals，anequallyrealharmonyalwayspresentedafixedstandardforourguidance。
　　ThisideaofaMoralSenseasthesourceandstandardofourmoralsentimentswassofardevelopedbyHutcheson，thattimeMoralSensetheoryofethicshadbeenmoregenerallyconnectedwithhisnamethanwiththatofitsrealoriginator。Hutchesonarguedthataswehaveexternalsenseswhichperceivesoundsandcolours，sowehaveinternalsenseswhichperceivemoralexcellenceandthecontrary。Thismoralsensehaditsanaloguesinoursenseofbeautyandharmony，oursympatheticsense，oursenseofhonour，ofdecency，andsoforth。Itwasaprimitivefacultyofournature，afactorincapableofresolutionintosimplerelements。Itcouldnot，forinstance，beresolvedintoaperceptionofutility，forbadactionswereoftenasusefulasgoodonesandyetfailedtomeetwithapprobation，norcoulditbeexplainedasamodeofsympathy，forwemightmorallyapproveevenofthevirtueswhichourenemiesmanifested。
　　BishopButler，likehiscontemporary，Hutcheson，alsofollowedLordShaftesburyinseekinginournaturalinstinctstheoriginofourmoralideas，ConsciencewithhimtakingtheplaceoftheMoralSense，fromitsbeingpossessed，ashethought，ofamoreauthoritativecharacter。Conscience，ac-cordingtoButler，wasafacultynaturaltoman，invirtueofwhichhewasamoralagent；afacultyorprincipleofthehumanheart，inkindandnaturesupremeoverallothers，andbearingitsownauthorityForbeingso。Usinglanguageaboutit，whichwemeetagainintheTheoryofAdamSmith，hespokeofitas"God'sviceroy，""thevoiceofGodwithinus，""theguideassignedtousbytheAuthorofournature。"Theobligationtoobeyitthereforerestedinthefactofitsbeingthelawofournature。

　　AdamSmith'stheorymustthereforebeunderstoodasanattempttoexplainwhattheIntuitionalistschoolreallygaveupasinexplicable；anditrepresentsthereactionagainstthatapriorimethodwhichtheyhademployedindealingwithmoralproblems。Inthatreaction，andinhisappealtothefactsofexperience，AdamSmithfollowedtheleadofbothHartleyandHume。Tenyearsbeforehim，timeformer，inhisObservationsonMan，hadsoughttoexplaintheexistenceofthemoralsense，bytracingitbacktoitslowesttermsinthepleasuresandpainsofsimplesensation，andmarkingitsgrowthinthegradualassociationofourideas。AndHume，afewyearslater，soughttodiscover"theuniversalprinciplefromwhichallcensureorapprobationwasultimatelyderived"bytheexperimentalmethodofinquiry；bycomparing，thatis，anumberofinstancesofqualitiesheldestimableontheonehandandqualitiesheldblameableontheother，andobservingwhatwasthecommonelementofeach。Fromsuchaninquiryheinferredthatthoseactsweregoodwhichwereusefulandthosebadwhichwereinjurious，andthatthefactoftheirbeingusefulorinjuriouswasthecauseoftheirgoodnessorbadness。
　　ThusitwillbeseenthatthequestionofchiefinterestinAdamSmith'stimewaswidelydifferentfromthatwhichhaddividedtheschoolsofantiquity。
　　Theaimorchiefgoodoflifewhichchieflyoccupiedthemhadrecededintotheback-ground；andthecontroversyconcerned，asHumedeclared，"thegeneralfoundationofmorals，"whethertheywerederivedfromReasonorfromSentiment，whethertheywerearrivedatbyachainofargumentandprocessofreasoningorbyacertainimmediatefeelingandinternalsense。
