Simple Alodes of Space.
Space roid of Body, equal toche smallest separate Particle OF Matter non
existing in Nature, tis sill Space Without Body; and makes as Great a
difference betreen Space and Body, as it it ere Meya rcoua, a distance as
ide as any in Nature. And cheretore il e suppose noc the void Space
necessaris toMotion, equal tothe least parcel of the divided solid Matter,
Duc to or  OFit, thelame consequence will alvays Follo ot Space ich
OUE MLaEECr.
9. 23. But the Oueltion beinghere, Whether he Ldea of SpaCC OT FX
tension, be the same with ehe Idea of Body, it is not necellary to prove the
real existence oF a Vacuum, Dut the Idea oF ic; irhich tis plain Men have.
Wrhen ther enquire and dispute, Whether there De a Vacuum or no: Por il
ther had nOE the Ldea oF Space withont Body, ther could nor make a
queltion about its existence: And il their Idea ot Body did noc include
in it Comething more thanthe bare Idea of Space, chey couldhave no douDé
about the plenitude of the Worid; and trould De as absurd to demand,
ertrecher chere vere Space ithout Body, as Whether there rere space
rithout Space, or Body ithout Body, since these vere bur different
Names oFthelame Idea.
6. 24.Tis true, the Idea oEFxtensonjoins it TelF (0 inseparably wich 2II
vilible, and most tansible Oualities, that it lutters us to see noonc, or seet
very fer external Objects, withour takcing in imprections of Fxtension t00.
This readinels of Fxtension to mako it self be talien norice of so constanty
rith orher Pdeas, has been the occasion, I guels, chat Pome have made tho
Whole ellence ot Body, 10 consist in Extension; ertrich is not much to
De mondred at, since some have had their Minds, Dy cheir Fres and
Touch, (the Busestot all our Senles,) (0 Tilled wich the Idea OE Fxter-
Fon, and as it ere wholly porsesled wich it, thar cher allored no exi
stence toany thine, thachad not Extension. IMall not nor argue with
those Nen, Wrho tatee the measure and possibility ol all Beins, only From
their narrom and gross Imasinations: but havine here to do ontr richi
thole, wrtro conclude the essence of Body to De Lxtension, becaule, they
Pay, ther cannot imagine any sensible Oualier of any Body without PX-
tention, IMall desire them to consider, Tharhad eliey reflected on their
Ideas of Fastes and Sinells, as much as on thole of sight and Pouch;
nay, had thes examined their Ideas of Punser and Thirst, and several
Ocher Pains, they rould hare Found, chat they included in them no Idea ot
Fxtension at all, erhich is but an affection oF Body, 25 ell as the rest dii-
corcrable by our Senses, Wtrich are scarce acure enoush to look into the
Pure Fsence OF ThingS.
5. 25. It those Ideas, Which are constaney joinedto all others, must
theretore be concluded to be the Rssence ot those Things, Wtrick hare
constanty chole Ideasjoined to them, and are inseparable trom them;
etien Onier is without doube the elsence of every thing. Por there is not
any Object ot sensation or Reflection, Wrhich docs not carry ith ic che
Idea oF one: But the eatenels oF chis Kind oF Arsument, e have alreads
Thewn Cufficiener.
6. 26. Toconclude, Wrhatever Men Pall chink concernins the exi-
Bence OF a Vacuum, chis is plain come, That e have as clear an Ldea of
Space distinct from Solidity, as re have oE Solidier distinct trom Motion,
or Biotion from Space. We have not any two more diltinct Ideas, aud
ve can as casilr conceire space ichont solidier, as e can conccive BO
dr Without Motion, thovoh ic De never (0 certain, that neither Body nOr
Morion can exist without Spaco. But Whether anr one will tatce Space
10 beontys a relation resultiris trom the Existence ol orher Beines at a di
