Let me write it out more at length: "We are altogether unable to conceive space as bounded--as finite; that is, as a whole _in the space_ beyond which there is no further space." "We find ourselves totally unable to imagine bounds, _in the space_ beyond which there is no further space." The words which I have added were already present implicitly.

What can the word "beyond" mean if it does not signify space beyond?
What Sir William and Mr.Spencer have asked us to do is to imagine a limited space with a _beyond_ and yet _no beyond_.
There is undoubtedly some reason why men are so ready to affirm that space is infinite, even while they admit that they do not know that the world of material things is infinite.

To this we shall come back again later.

But if one wishes to affirm it, it is better to do so without giving a reason than it is to present such arguments as the above.

SPACE AS INFINITELY DIVISIBLE .-- For more than two thousand years men have been aware that certain very grave difficulties seem to attach to the idea of motion, when we once admit that space is infinitely divisible.
