Led. Of Mixture. The Principles, Ke, 
223 

§. 6. I thall therefore endeavour to open the true Netureof Mixture, 
And I fhall build my. Doérize upon the Common Notions of Senfe ; 
which none ca deny 5 and every one may conceive of. In ordet to 
which, I fhall take leaveto lay down fome Propofitions, of the Princi= 
ples of all-wixed Bodies.

Of the Principles of Bodies. 
rq ND firlt; by Principles, I mean Atomes, or certaiti 
) Sorts of Atomes, or of the fimpleft of Bodies. For 
otherwife they would not be Principles; for a 
compounded Principle, in ftritt {peaking, is a Cone 
tradidion, Even as Fives, Threes, or Two's are 
k not the Principles of Number, but Unites. 
SO SE 2, §. Whence, fecondly, it follows, that they 
are alfo Indivifible. Not Mathematically 5 for the Atomes of every Prin- 
ciple have their Dimenfions. But Phyfically 5 and fo, what is but oxe, 
cannot be made #wo.  Ifit beasked, Whether aStick cut with aKnife, 
be not of one, made two? I fay, that a Stick, is not one Body, but 
zany millions of Bodies; that is, of Atomes; not any one whereof is 
divided within it felf, but only they are feparated one from another, 
where the Knife forceth its way. As in the drawing of a mans Finger 
through a Heap of Corns there is no Divifion made in any one 
Grain, but only a feparation of them one from another, all remaining 
ftill in themfelves entire. I fay, therefore, that what is Phyfically 



one, is alfo molt firm, and Indivifible, that is, Ivepenctrable : for Penetration 
is but the Separation, not the Divifion of Atomes. 
3. §. Hence, thirdly, they are alfo Immutable. For that which 
cannot be divided, cannot be chang’d. So that of the whole World 
of Atomes, not any one hath ever fuffer'd, or can fuffer the leaft mus 
tation. Hereupon is grounded the Conftancy of Caufes and Effects, So 
that, in all Gezerations, itis not lefS certain, that the felf fame Prix. 
a is till propagated from the fame; than, that Man is from Map; 
herefore, compounded Bodies are generated ; but Principles are not; 
but only propagated; that is, in every Generation, they pafs; in them- 
felves unaltered, from one Body, into another. 
4. §. If Principles, or Atomes are all Immutable , it again follows » 
That they are of Divers Kizds. For one and the fame Principle, or Kind 
of Atomes, will {tillmake the Same Thing, and have the fame Effed : fo 
that_all Geverations would then be the Same, Wherefore, fince they 
are Immutable, they mutt be Divers. 
5. §. This Diverfity, for the fame reafon, isnot fmall, but very 
Numerous. For as the World, taken together, is Natures Shop; fo the 
Principles of Things are her Tools; and her Materials. Wherefore; ag 
it {peaks the goodne/s of a Shop 3 {othe Perfecfionof the Univerfe, That it 
is furnifhed with many Too/s wherewith,and many Materials whereupon 
to work, And confequently, that Philofophy beareth beft its own name 3 
which doth not ftrain all totwo or three Principles, liketwo or ae
