5. And therefore to _make parts_, or to _part_ or DIVIDE space or _time_, is nothing else but to consider one and another within the same; so that if any man _divide_ space or time, the diverse conceptions he has are more, by one, than the parts he makes; for his first conception is of that which is to be divided, then of some part of it, and again of some other part of it, and so forwards as long as he goes on in dividing. But it is to be noted, that here, by _division_, I do not mean the severing or pulling asunder of one space or time from another (for does any man think that one hemisphere may be separated from the other hemisphere, or the first hour from the second?) but diversity of consideration; so that division is not made by the operation of the hands but of the mind. [Sidenote: One.] 6. When space or time is considered among other spaces or times, it is said to be ONE, namely _one of them_; for except one space might be added to another, and subtracted from another space, and so of time, it would be sufficient to say space or time simply, and superfluous to say one space or one time, if it could not be conceived that there were another. The common definition of _one_, namely, that _one is that which is undivided_, is obnoxious to an absurd consequence; for it may thence be inferred, that whatsoever is divided is many things, that is, that every divided thing, is divided things, which is insignificant. [Sidenote: Number.] 7. NUMBER is _one_ and _one_, or _one one_ and _one_, and so forwards; namely, _one_ and _one_ make the number _two_, and _one one_ and _one_ the number _three_; so are all other numbers made; which is all one as if we should say, _number is unities_. [Sidenote: Composition.] 8. To COMPOUND space of spaces, or time of times, is first to consider them one after another, and then altogether as one; as if one should reckon first the head, the feet, the arms, and the body, severally, and then for the account of them all together put _man_. And that which is so put for all the severals of which it consists, is called the WHOLE; and those severals, when by the division of the whole they come again to be considered singly, are parts thereof; and therefore the _whole_ and _all the parts taken together_ are the same thing. And as I noted above, that in _division_ it is not necessary to pull the parts asunder; so in _composition_, it is to be understood, that for the making up of a whole there is no need of putting the parts together, so as to make them touch one another, but only of collecting them into one sum in the mind. For thus all men, being considered together, make up the whole of mankind, though never so much dispersed by time and place; and twelve hours, though the hours of several days, may be compounded into one number of twelve. [Sidenote: The whole.]
