　　Duringthefifteenthcenturyandtheearlieryearsofthesixteenththerevivaloflearning，theinventionofprinting，andthegreatvoyagesofdiscoverygaveanewimpulsetothought，andinthismedicalscienceshared：theoldtheologicalwayofthinkingwasgreatlyquestioned，andgaveplaceinmanyquarterstoadifferentwayoflookingattheuniverse。
　　InthesixteenthcenturyParacelsusappears——agreatgenius，doingmuchtodevelopmedicinebeyondthereachofsacredandscholastictradition，thoughstillfetteredbymanysuperstitions。Moreandmore，inspiteoftheologicaldogmas，camearenewalofanatomicalstudiesbydissectionofthehumansubject。ThepracticeoftheoldAlexandrianSchoolwasthusresumed。Mundinus，ProfessorofMedicineatBolognaearlyinthefourteenthcentury，daredusethehumansubjectoccasionallyinhislectures；butfinallycameafargreaterchampionofscientifictruth，AndreasVesalius，founderofthemodernscienceofanatomy。Thebattlewagedbythismanisoneofthegloriesofourrace。
　　FromtheoutsetVesaliusprovedhimselfamaster。Inthesearchforrealknowledgeheriskedthemostterribledangers，andespeciallythechargeofsacrilege，foundedupontheteachingsoftheChurchforages。Aswehaveseen，evensuchmenintheearlyChurchasTertullianandSt。Augustineheldanatomyinabhorrence，andthedecretalofPopeBonifaceVIIIwasuniversallyconstruedasforbiddingalldissection，andasthreateningexcommunicationagainstthosepractisingit。ThroughthissacredconventionalismVesaliusbrokewithoutfear；despiteecclesiasticalcensure，greatoppositioninhisownprofession，andpopularfury，hestudiedhissciencebytheonlymethodthatcouldgiveusefulresults。Noperildauntedhim。Tosecurematerialforhisinvestigations，hehauntedgibbetsandcharnel-houses，bravingthefiresoftheInquisitionandthevirusoftheplague。Firstofallmenhebegantoplacethescienceofhumananatomyonitssolidmodernfoundations——oncarefulexaminationandobservationofthehumanbody：thiswashisfirstgreatsin，anditwassoonaggravatedbyoneconsideredevengreater。
　　PerhapsthemostunfortunatethingthathaseverbeendoneforChristianityisthetyingittoformsofsciencewhicharedoomedandgraduallysinking。Justas，inthetimeofRogerBacon，excellentmendevotedalltheirenergiestobindingChristianitytoAristotle；justas，inthetimeofReuchlinandErasmus，theyinsistedonbindingChristianitytoThomasAquinas；so，inthetimeofVesalius，suchmenmadeeveryefforttolinkChristianitytoGalen。Thecryhasbeenthesameinallages；itisthesamewhichwehearinthisageforcurbingscientificstudies：thecryforwhatiscalled“soundlearning。”WhetherstandingforAristotleagainstBacon，orforAquinasagainstErasmus，orforGalenagainstVesalius，thecryisalwaysfor“soundlearning“：
　　theideaalwayshasbeenthattheolderstudiesare“SAFE。”
　　Attwenty-eightyearsofageVesaliusgavetotheworldhisgreatworkonhumananatomy。Withitendedtheoldandbeganthenew；
　　itsresearches，bytheirthoroughness，wereatriumphofscience；
　　itsillustrations，bytheirfidelity，wereatriumphofart。
　　Toshieldhimself，asfaraspossible，inthebattlewhichheforesawmustcome，VesaliusdedicatedtheworktotheEmperorCharlesV，andinhisprefacehearguesforhismethod，andagainsttheparrotrepetitionsofthemediaevaltext-books；healsocondemnsthewretchedanatomicalpreparationsandspecimensmadebyphysicianswhoutterlyrefusedtoadvancebeyondtheancientmaster。Theparrot-likerepeatersofGalengavebattleatonce。Afterthemanneroftheirtimetheirfirstmissileswereepithets；and，thevastarsenalofthesehavingbeenexhausted，theybegantousesharperweapons——weaponstheologic。
　　Inthiscasetherewereespecialreasonswhythetheologicalauthoritiesfeltcalledupontointervene。First，therewastheoldideaprevailingintheChurchthatthedissectionofthehumanbodyisforbiddentoChristians：thiswasusedwithgreatforceagainstVesalius，butheatfirstgainedatemporaryvictory；for，aconferenceofdivineshavingbeenaskedtodecidewhetherdissectionofthehumanbodyissacrilege，gaveadecisioninthenegative。
　　Thereasonwassimple：thegreatEmperorCharlesVhadmadeVesaliushisphysicianandcouldnotsparehim；but，ontheaccessionofPhilipIItothethroneofSpainandtheNetherlands，thewholescenechanged。VesaliusnowcomplainedthatinSpainhecouldnotobtainevenahumanskullforhisanatomicalinvestigations：themedicalandtheologicalreactionistshadtheirway，andtoallappearancetheyhave，asarule，haditinSpaineversince。AslateasthelastyearsoftheeighteenthcenturyanobservantEnglishtravellerfoundthattherewerenodissectionsbeforemedicalclassesintheSpanishuniversities，andthatthedoctrineofthecirculationofthebloodwasstilldenied，morethanacenturyandahalfafterSarpiandHarveyhadprovedit。
　　AnothertheologicalideabarredthepathofVesalius。ThroughouttheMiddleAgesitwasbelievedthatthereexistsinmanaboneimponderable，incorruptible，incombustible——thenecessarynucleusoftheresurrectionbody。Beliefinaresurrectionofthephysicalbody，despiteSt。Paul’sEpistletotheCorinthians，hadbeenincorporatedintotheformulaevolvedduringtheearlyChristiancenturiesandknownastheApostles’Creed，andwasheldthroughoutChristendom，“always，everywhere，andbyall。”
　　Thishypotheticalbonewasthereforeheldingreatveneration，andmanyanatomistssoughttodiscoverit；butVesalius，revealingsomuchelse，didnotfindit。Hecontentedhimselfwithsayingthatheleftthequestionregardingtheexistenceofsuchabonetothetheologians。Hecouldnotlie；hedidnotwishtofighttheInquisition；andthushefellundersuspicion。
　　ThestrengthofthistheologicalpointmaybejudgedfromthefactthatnolesseminentasurgeonthanRiolanconsultedtheexecutionertofindoutwhether，whenheburnedacriminal，allthepartswereconsumed；andonlythenwastheanswerreceivedwhichfatallyunderminedthissuperstition。Yet，in1689wefinditstilllingeringinFrance，stimulatingoppositionintheChurchtodissection。Evenaslateastheeighteenthcentury，Bernouillihavingshownthatthelivinghumanbodyconstantlyundergoesaseriesofchanges，sothatallitsparticlesarerenewedinagivennumberofyears，somuchillfeelingwasdrawnuponhim，fromtheologians，whosawinthisstatementdangertothedoctrineoftheresurrectionofthebody，thatforthesakeofpeacehestruckouthisargumentonthissubjectfromhiscollectedworks。[320]
