Perhaps　someone　else　has。　Perhaps　no　one　else　has。　In　either　case；　we　have　good　reason　for　humility。




CHAPTER　4　　　　A　UNIVERSE　NOT　MADE　FOR　US

　

　

The　Sea　of　Faith

Was　once；　too；　at　the　full；　and　round　earth's　shore

Lay　like　the　folds　of　a　bright　girdle　furl'd。

But　now　I　only　hear

Its　melancholy；　long；　withdrawing　roar；

Retreating；　to　the　breath

Of　the　night…wind；　down　the　vast　edges　drear

And　naked　shingles　of　the　world。

—MATTHEW　ARNOLD；　〃DOVER　BEACH〃　（1867）

What　a　beautiful　sunset；〃　we　say；　or　〃I'm　up　before　sunrise。〃　No　matter　what　the　scientists　allege；　in　everyday　speech　we　often　ignore　their　findings。　We　don't　talk　about　the　Earth　turning；　but　about　the　Sun　rising　and　setting。　Try　formulating　it　in　Copernican　language。　Would　you　say；　〃Billy；　be　home　by　the　time　the　Earth　has　rotated　enough　so　as　to　occult　the　Sun　below　the　local　horizon〃？　Billy　would　be　long　gone　before　you're　finished。　We　haven't　been　able　even　to　find　a　graceful　locution　that　accurately　the　Heliocentric　insight。　We　at　the　center　and　everything　else　circling　us　is　built　into　our　languages；　we　teach　it　to　our　children。　We　are　unreconstructed　geocentrists　hiding　behind　a　Copernican　veneer。*

*　One　of　the　few　quasi…Copernican　expressions　in　English　is　〃The　Universe　doesn't　revolve　around　you〃…an　astronomical　truth　intended　to　bring　fledgling　narcissists　down　to　Earth。

In　1633　the　Roman　Catholic　Church　condemned　Galileo　for　teaching　that　the　Earth　goes　around　the　Sun。　Let's　take　a　closer　look　at　this　famous　controversy。　In　the　preface　to　his　book　paring　the　two　hypotheses—an　Earth…centered　and　a　Sun…centered　universe—Galileo　had　written；

The　celestial　phenomena　will　be　examined；　strengthening　the　Copernican　hypothesis　until　it　might　seem　that　this　must　triumph　absolutely。

And　later　in　the　book　he　confessed；

Nor　can　I　ever　sufficiently　admire　＇Copernicus　and　his　followers＇；　they　have　through　sheer　force　of　intellect　done　such　violence　to　their　own　senses　as　to　prefer　what　reason　told　them　over　what　sensible　experience　plainly　showed　them　。　。　。

The　Church　declared；　in　its　indictment　of　Galileo；

The　doctrine　that　the　earth　is　neither　the　center　of　the　universe　nor　immovable；　but　moves　even　with　a　daily　rotation；　is　absurd；　and　both　psychologically　and　theologically　false；　and　at　the　least　an　error　of　faith。

Galileo　replied；

The　doctrine　of　the　movements　of　the　earth　and　the　fixity　of　the　sun　is　condemned　on　the　ground　that　the　Scriptures　speak　in　many　places　of　the　sun　moving　and　the　earth　standing　still　。　。　。　It　is　piously　spoken　that　the　Scriptures　cannot　lie。　But　none　will　deny　that　they　are　frequently　abstruse　and　their　true　meaning　difficult　to　discover；　and　more　than　the　bare　words　signify。　I　think　that　in　the　discussion　of　natural　problems　we　ought　to　begin　not　with　the　Scriptures；　but　with　experiments　and　demonstrations。

But　in　his　recantation　（June　22；　1633）　Galileo　was　made　to　say；

Having　been　admonished　by　the　Holy　Office　entirely　to　abandon　the　false　opinion　that　the　Sun　was　the　center　of　the　universe　and　immovable；　and　that　the　Earth　was　not　the　center　of　the　same　and　that　it　moved　。　。　。　I　have　been　。　。　。　suspected　of　heresy；　that　is；　of　having　held　and　believed　that　the　Sun　is　the　center　of　the　universe　and　immovable；　and　that　the　Earth　is　not　the　center　of　the　same；　and　that　it　does　move　。　。　。　1　abjure　with　a　sincere　heart　and　unfeigned　faith；　I　curse　and　detest　the　same　errors　and　heresies；　and　generally　all　and　every　error　and　sect　contrary　to　the　Holy　Catholic　Church。

It　took　the　Church　until　1832　to　remove　Galileo's　work　from　its　list　of　books　which　Catholics　were　forbidden　to　read　at　the　risk　of　dire　punishment　of　their　immortal　souls。

Pontifical　disquiet　with　modern　science　has　ebbed　and　flowed　since　the　time　of　Galileo。　The　high…water　mark　in　recent　history　is　the　1864　Syllabus　of　Errors　of　Pius　IX；　the　pope　who　also　convened　the　Vatican　Council　at　which　the　doctrine　of　papal　infallibility　was；　at　his　insistence；　first　proclaimed。　Here　are　a　few　excerpts：

Divine　revelation　is　perfect　and；　therefore；　it　is　not　subject　to　continual　and　indefinite　progress　in　order　to　correspond　with　the　progress　of　human　reason　。　。　。　No　man　is　free　to　embrace　and　profess　that　religion　which　he　believes　to　be　true；　guided　by　the　light　of　reason　。　。　。　The　Church　has　power　to　define　dogmatically　the　religion　of　the　Catholic　Church　to　be　the　only　true　religion　。　。　。　It　is　necessary　even　in　the　present　day　that　the　Catholic　religion　shall　be　held　as　the　only　religion　of　the　state；　to　the　exclusion　of　all　other　forms　of　worship　。　。　。　The　civil　liberty　of　every　mode　of　worship；　and　full　power　given　to　all　of　openly　and　publicly　manifesting　their　opinions　and　their　ideas　conduce　more　easily　to　corrupt　the　morals　and　minds　of　the　people　。　。　。　The　Roman　Pontiff　cannot　and　ought　not　to　reconcile　himself　or　agree　with；　progress；　liberalism　and　modern　civilization。

To　its　credit；　although　belatedly　and　reluctantly；　the　Church　in　1992　repudiated　its　denunciation　of　Galileo。　It　still　cannot　quite　bring　itself；　though；　to　see　the　significance　of　its　opposition。　In　a　1992　speech　Pope　John　Paul　II　argued；

From　the　beginning　of　the　Age　of　Enlightenment　down　to　our　own　day；　the　Galileo　case　has　been　a　sort　of　〃myth〃　in　which　the　image　fabricated　out　of　the　events　is　quite　far　removed　from　reality。　In　this　perspective；　the　Galileo　case　was　a　symbol　of　the　Catholic　Church's　supposed　rejection　of　scientific　progress；　or　of　〃dogmatic〃　obscurantism　opposed　to　the　free　search　for　truth。

But　surely　the　Holy　Inquisition　ushering　the　elderly　and　infirm　Galileo　in　to　inspect　the　instruments　of　torture　in　the　dungeons　of　the　Church　not　only　admits　but　requires　just　such　an　interpretation。　This　was　not　mere　scientific　caution　and　restraint；　a　reluctance　to　shift　a　paradigm　until　pelling　evidence；　such　as　the　annual　parallax；　was　available。　This　was　fear　of　discussion　and　debate。　Censoring　alternative　views　and　threatening　to　torture　their　proponents　betray　a　lack　of　faith　in　the　very　doctrine　and　parishioners　that　are　ostensibly　being　protected。　Why　were　threats　and　Galileo's　house　arrest　needed？　Cannot　truth　defend　itself　in　its　confrontation　with　error？

The　Pope　does；　though；　go　on　to　add：

The　error　of　the　theologians　of　the　time；　when　they　maintained　the　centrality　of　the　earth；　was　to　think　that　our　understanding　of　the　physical　world's　structure　was　in　soiree　way　imposed　by　the　literal　sense　of　Sacred　Scriptures。

Here　indeed　considerable　progress　has　been　made—although　proponents　of　fundamentalist　faiths　will　be　distressed　to　hear　from　the　Pontiff　that　Sacred　Scripture　is　not　always　literally　true。

But　if　the　Bible　is　not　everywhere　literally　true；　which　parts　are　divinely　inspired　and　which　are　merely　fallible　and　human？　As　soon　as　we　admit　that　there　are　scriptural　mistakes　（or　concessions　to　the　ignorance　of　the　times）；　then　how　can　the　Bible　be　an　inerrant　guide　to　ethics　and　morals？　Might　sects　and　individuals　now　accept　as　authentic　the　parts　of　the　Bible　they　like；　and　reject　those　that　are　inconvenient　or　burdensome？　Prohibitions　against　murder；　say；　are　essential　for　a　society　to　function；　but　if　divine　retribution　for　murder　is　considered　implausible；　won't　more　people　think　they　can　get　away　with　it？

Many　felt　that　Copernicus　and　Galileo　were　up　to　no　good　and　erosive　of　the　social　order。　Indeed　any　challenge

from　any　source；　to　the　literal　truth　of　the　Bible　might　have　such　consequences。　We　can　readily　see　how　science　began　to　make　people　nervous。　Instead　of　criticizing　those　who　perpetuated　the　myths；　public　rancor　was　directed　at　those　who　discredited　them。



OUR　ANCESTORS　UNDERSTOOD　origins　by　extrapolating　from　their　own　experience。　How　else　could　they　have　done　it？　So　the　Universe　was　hatched　from　a　cosmic　egg；　or　conceived　in　the　sexual　congress　of　a　mother　god　and　a　father　god；　or　was　a　kind　of　product　of　the　Creator's　workshop—perhaps　the　latest　of　many　flawed　attempts。　And　the　Universe　was　not　much　bigger　than　we　see；　and　not　much　older　than　our　written　or　oral　records；　and　nowhere　very　different　from　places　that　we　know。
