- Idea of Soliditi.
- may approach one another, ithout touchine or displacins any solic
- chino, till cheir Superticies come to meet; Wvhereby, Tthink, we have
- tho clear Idea Ol Space without soliditr. For (not 1050(0 tar as aninihiila-
- tion ot any particular BOdY) Pasli, WVhether a Plan cannothavo che Idea
- Otthe motion ol one linele Body alone, rithout anr other succcedins
- immediarelr into ies Place: Wrhich, I chink, tis erident he Can; thC
- Idea oFMocion in one Bodr, no more includino the idea ot Motion in q-
- nother, than the Idea oF a square Figure in one Body includes
- the idea ot a square Pisure in anocher. I do not ask, Whether
- Bodies do P0 exist, that the motion of orie Body cannor reallr bc
- Wichout the morion ol another: To derermine this cither way, is to beo
- the uection Por or asains a Vacuum. But my Oueltion is, Whether
- one cannochare the Idea ol one Body moved, hilst ochers are at rest:
- and I chintc. this no one will denr: IF (0, then the Place it delerted,
- sires us the Idea oF pure Space Without Soliditr, Whereinto another Body
- mas enter, ithout cither Relistance or Protrusion of any thing. When
- the Suelcer in a Pump is drarrn, the space it Alled in the Fube is certain-
- lx the lamme, Wrhether any other bodr follons the motion ofthe Sucter or
- nO; nor does it imply a contradiction, That upon the motion oloneB0.
- dr, another chat is ontr contiguous to it, Mould not tollo it. Thene-
- cessitr oF such a motion, is built onty on the Supposition, Thac thie Worid
- is Full; buc not on the distinet Ideas oF Space and Soliditr, irhich are a5
- different, as Relistance and not Relictonce, Protrusion and nor Protrusion:
- And that Men have Ideas ol Space, Without Body, their very Disputes a
- bout a Vacuum plainly demonstrate, asis eved in another Placc.
- 6. 4. Solidiry is hrereby also differenced from FTardness, in that Solidi-
- tr consilts in repletion, and so an ulter Fxclusion ot ocher Bodies out of
- the space it possesses: BuF FPardness, in a tirm Cohesion oF, the parts OF
- Matter, makins up masses of a sensiblo bulk; (0 that the whole docs not
- casils chanse its Fisure. And indced, IPard and Solt, are, as apprehended
- by us, ouls relatire Terms, eo the Constitutions of our Bodies; that beins
- oeneralIY Calld hard by us, ertich ill put us to Pain, (ooner than chanse
- Figure by the presture ot ans part of our Bodies; and that on the contra-
- ry, TolE, Wrhich chanses the Siruation of its parts upon an calie and un.
- Paintul touch.
- But chis Difficuley OF changins the Situation oF the sensible parts a-
- monost chemselves, or olthe Fisure of the whole; sires no more Solidi.
- ey tothe hardest Body in the Wortd, than to the (otrest; nor is an Ada-

- Whieh there is nothins but Water or Air, than if there De an Adamant
- betreen them: vet it isnot, chat elie parts of the Adamant are more solid
- than those oF Water, or resist more; but becaule the parts of Water, beino

- as much as the Diamond; and trrould be as impostible by any force, t0

- comins together ofany tro ocher Bodies, is it benot purout ol the may.
- Dut remain betrreen them, as the hardest that can be found or imaxined.
