[D]ThejournalistIanLeslie,inhisnewandenjoyablebookCurious:

[E]Wearesuffering,hewrites,froma“serendipitydeficit.”Theword“serendipity”wascoinedbyHoraceWalpoleinan1854letter,fromataleofthreeprinceswho“werealwaysmakingdiscoveries,byaccident,ofthingstheywerenotinsearchof.”LeslieworriesthattheriseoftheInternet,amongothersocialandtechnologicalchanges,hasreducedourappetiteforaimlessadventures.Nolongerhavewetheinclinationtoletourselveswanderthroughfieldsofknowledge,readytobesurprised.Instead,weseekonlytheinformationwewant.

[H]Moreover,inordertobecurious,‘"youhavetobeawareofagapinyourknowledgeinthefirstplace.''AlthoughLeslieperhapspaintsabitbroadlyincontendingthatmostofusareunawareofhowmuchwedon’tknow,he’ssurelyrighttopointoutthattheproblemisgrowing:

“Googlecangiveusthepowerfulillusionthatallquestionshavedefiniteanswers.”

[I]Indeed,Google,forwhichLeslieexpressesadmiration,isalsohisfrequentwhippingboy（替罪羊）•HequotesGoogleco-founderLarryPagetotheeffectthatthe“perfectsearchengine”will“understandexactlywhatImeanandgivemebackexactlywhatIwant.”Elsewhereinthebook,Lesliewrites:

“Oneshouldenteritvaguely,almostinadream,andallowwhatistherefreelytoattractandinfluencetheeye.Towalktheroundsofthebookshops,dippinginascuriositydictates,shouldbeanafternoon’sentertainment.”Ifonly!

[K]Citingtheworkofpsychologistsandcognitive（认知的）scientists，Lesliecriticizesthereceivedwisdomthatacademicsuccessistheresultofacombinationofintellectualtalentandhardwork.Curiosity,heargues,isthethirdkeyfactor—andadifficultonetopreserve.Ifnotcultivated,itwillnotsurvive:

“Childhoodcuriosityisacollaborationbetweenchildandadult.Thesurestwaytokillitistoleaveitalone.”
