We need not force our imagination to conceive such very small lines for infinitesimals. They may every whit as well be imagin'd big as little, since that the integer must be infinite.

Evident that wch has an infinite number of parts must be infinite.

We cannot imagine a line or space infinitely great—therefore absurd to talk or make propositions about it.

We cannot imagine a line, space, &c., quovis lato majus. Since yt what we imagine must be datum aliquod; a thing can't be greater than itself.

If you call infinite that wch is greater than any assignable by another, then I say, in that sense there may be an infinite square, sphere, or any other figure, wch is absurd.

Qu. if extension be resoluble into points it does not consist of?

No reasoning about things whereof we have no ideas[52]; therefore no reasoning about infinitesimals.

No word to be used without an idea.
