• "Now Leibniz could retort that that this argument depends crucially on the assumption that the portion of the curve between abscissae 0 and dx is indeed straight."
• "But if one grants, as Leibniz does, that that there is an infinitesimal straight stretch of the curve (a side, that is, of an infinilateral polygon coinciding with the curve) between abscissae 0 and e, say, which does not reduce to a single point then e cannot be equated to 0 and yet the above argument shows that e2 = 0."
• "It is a paper you cannot make head nor tail of, and at the end come five or six long folded diagrams that open out and show peculiar zigzag tracings, flashes of lightning overdone, or sinuous inexplicable things called “smoothed curves” set up on ordinates and rooting in abscissae — and things like that."
