A Vacuum beyond the utmost bounds of Body.       §21. But to return to our Idea of Space. If Body be not supposed
infinite, which, I think, no one will affirm, I would ask, Whether, if
God placed a Man at the extremity of corporeal Beings, he could not
stretch his Hand beyond his Body? If he could, then he would put
— 176 —
his Arm, where there was before Space without Body; and if there he
spread his Fingers, there would still be Space between them without
Body: If he could not stretch out his Hand, it must be because of
some external hindrance; (for we suppose him alive, with such a
power of moving the parts of his Body, that he hath now, which is
not in it self impossible, if God so pleased to have it; or at least it is
not impossible for God so to move him:) And then I ask, Whether
that which hinders his Hand from moving outwards, be Substance
or Accident, Something or Nothing? And when they have resolved
that, they will be able to resolve themselves, what that is, which is
or may be between two Bodies at a distance, that is not Body, has
no Solidity. In the mean time, the Argument is at least as good,
That where nothing hinders, (as beyond the utmost bounds of all
Bodies) a Body put into motion may move on, as where there is
nothing between, there two Bodies must necessarily touch. For
pure Space between, is sufficient to take away the necessity of
mutual Contact; but bare Space in the way, is not sufficient to stop
Motion. The truth is, these Men must either own, that they think
Body infinite, though they are loth to speak it out, or else affirm,
that Space is not Body. For I would fain meet with that thinking
Man, that can, in his Thoughts, set any bounds to Space, more than
he can to Duration; or by thinking, hope to arrive at the end of
either: And therefore if his Idea of Eternity be infinite, so is his Idea
of Immensity; they are both finite or infinite alike.
