For, if the very mathematical centre of the central
particle be not accurately in the very mathematical centre of the
attractive power of the whole mass, the particle will not be attracted
equally on all sides. And much harder is it to suppose all the
particles, in an infinite space, should be so accurately poised, one
among another, as to stand still in a perfect equilibrium. For I reckon
this as hard as to make not one needle only, but an infinite number of
them, (so many as there are particles in an infinite space,) stand
accurately poised upon their points. Yet I grant it possible, at least,
by a divine power; and, if they were once to be placed, I agree with
you, that they would continue in that posture without motion, for ever,
unless put into new motion by the same power. When, therefore, I said,
that matter evenly spread through all space, would convene, by its
gravity, into one or more great masses, I understand it of matter not
resting in an accurate poise."
Let not it be thought irreverence to this great name, if I observe, that
by "matter evenly spread" through infinite space, he now finds it
necessary to mean "matter not evenly spread." Matter not evenly spread
will, indeed, convene, but it will convene as soon as it exists.
