Theideaswehavebelongingandpeculiartospirit，arethinking，andwill，orapowerofputtingbodyintomotionbythought，and，whichisconsequenttoit，liberty。For，asbodycannotbutcommunicateitsmotionbyimpulsetoanotherbody，whichitmeetswithatrest，sothemindcanputbodiesintomotion，orforbeartodoso，asitpleases。Theideasofexistence，duration，andmobility，arecommontothemboth。

22。Ourcomplexideaofanimmaterialspiritandourcomplexideaofbodycompared。Letuscompare，then，ourcomplexideaofanimmaterialspiritwithourcomplexideaofbody，andseewhethertherebeanymoreobscurityinonethanintheother，andinwhichmost。Ourideaofbody，asIthink，isanextendedsolidsubstance，capableofcommunicatingmotionbyimpulse:andourideaofsoul，asanimmaterialspirit，isofasubstancethatthinks，andhasapowerofexcitingmotioninbody，bywilling，orthought。These，Ithink，areourcomplexideasofsoulandbody，ascontradistinguished；andnowletusexaminewhichhasmostobscurityinit，anddifficultytobeapprehended。Iknowthatpeoplewhosethoughtsareimmersedinmatter，andhavesosubjectedtheirmindstotheirsensesthattheyseldomreflectonanythingbeyondthem，areapttosay，theycannotcomprehendathinkingthing，whichperhapsistrue:butIaffirm，whentheyconsideritwell，theycannomorecomprehendanextendedthing。
23。Cohesionofsolidpartsinbodyashardtobeconceivedasthinkinginasoul。Ifanyonesaysheknowsnotwhatitisthinksinhim，hemeansheknowsnotwhatthesubstanceisofthatthinkingthing:Nomore，sayI，knowshewhatthesubstanceisofthatsolidthing。Further，ifhesaysheknowsnothowhethinks，Ianswer，Neitherknowshehowheisextended，howthesolidpartsofbodyareunited，orcoheretogethertomakeextension。Forthoughthepressureoftheparticlesofairmayaccountforthecohesionofseveralpartsofmatterthataregrosserthantheparticlesofair，andhaveporeslessthanthecorpusclesofair，yettheweightorpressureoftheairwillnotexplain，norcanbeacauseofthecoherenceoftheparticlesofairthemselves。Andifthepressureoftheaether，oranysubtilermatterthantheair，mayunite，andholdfasttogether，thepartsofaparticleofair，aswellasotherbodies，yetitcannotmakebondsforitself，andholdtogetherthepartsthatmakeupeverytheleastcorpuscleofthatmateriasubtilis。
Sothatthathypothesis，howingeniouslysoeverexplained，byshowingthatthepartsofsensiblebodiesareheldtogetherbythepressureofotherexternalinsensiblebodies，reachesnotthepartsoftheaetheritself；andbyhowmuchthemoreevidentitproves，thatthepartsofotherbodiesareheldtogetherbytheexternalpressureoftheaether，andcanhavenootherconceivablecauseoftheircohesionandunion，bysomuchthemoreitleavesusinthedarkconcerningthecohesionofthepartsofthecorpusclesoftheaetheritself:whichwecanneitherconceivewithoutparts，theybeingbodies，anddivisible，noryethowtheirpartscohere，theywantingthatcauseofcohesionwhichisgivenofthecohesionofthepartsofallotherbodies。
24。Notexplainedbyanambientfluid。But，intruth，thepressureofanyambientfluid，howgreatsoever，canbenointelligiblecauseofthecohesionofthesolidpartsofmatter。For，thoughsuchapressuremayhindertheavulsionoftwopolishedsuperficies，onefromanother，inalineperpendiculartothem，asintheexperimentoftwopolishedmarbles；yetitcanneverintheleasthindertheseparationbyamotion，inalineparalleltothosesurfaces。

28。Communicationofmotionbyimpulse，orbythought，equallyunintelligible。Anotherideawehaveofbodyis，thepowerofcommunicationofmotionbyimpulse；andofoursouls，thepowerofexcitingmotionbythought。Theseideas，theoneofbody，theotherofourminds，everyday’sexperienceclearlyfurnishesuswith:butifhereagainweinquirehowthisisdone，weareequallyinthedark。
For，inthecommunicationofmotionbyimpulse，whereinasmuchmotionislosttoonebodyasisgottotheother，whichistheordinariestcase，wecanhavenootherconception，butofthepassingofmotionoutofonebodyintoanother；which，Ithink，isasobscureandinconceivableashowourmindsmoveorstopourbodiesbythought，whichweeverymomentfindtheydo。Theincreaseofmotionbyimpulse，whichisobservedorbelievedsometimestohappen，isyethardertobeunderstood。Wehavebydailyexperienceclearevidenceofmotionproducedbothbyimpulseandbythought；butthemannerhow，hardlycomeswithinourcomprehension:weareequallyatalossinboth。Sothat，howeverweconsidermotion，anditscommunication，eitherfrombodyorspirit，theideawhichbelongstospiritisatleastasclearasthatwhichbelongstobody。Andifweconsidertheactivepowerofmoving，or，asImaycallit，motivity，itismuchclearerinspiritthanbody；sincetwobodies，placedbyoneanotheratrest，willneveraffordustheideaofapowerintheonetomovetheother，butbyaborrowedmotion:whereasthemindeverydayaffordsusideasofanactivepowerofmovingofbodies；andthereforeitisworthourconsideration，whetheractivepowerbenottheproperattributeofspirits，andpassivepowerofmatter。Hencemaybeconjecturedthatcreatedspiritsarenottotallyseparatefrommatter，becausetheyarebothactiveandpassive。Purespirit，viz。God，isonlyactive；purematterisonlypassive；thosebeingsthatarebothactiveandpassive，wemayjudgetopartakeofboth。Butbethatasitwill，Ithink，wehaveasmanyandasclearideasbelongingtospiritaswehavebelongingtobody，thesubstanceofeachbeingequallyunknowntous；andtheideaofthinkinginspirit，asclearasofextensioninbody；andthecommunicationofmotionbythought，whichweattributetospirit，isasevidentasthatbyimpulse，whichweascribetobody。Constantexperiencemakesussensibleofboththese，thoughournarrowunderstandingscancomprehendneither。
For，whenthemindwouldlookbeyondthoseoriginalideaswehavefromsensationorreflection，andpenetrateintotheircauses，andmannerofproduction，wefindstillitdiscoversnothingbutitsownshort-sightedness。
