goes under the name of theory of limits, would be rid of the increments, rid also of their infinite or arbitrary smallness, and of the difficulty of again doing away with the rest of the terms of a series other than the first, or rather other than just the coefficient of the first, terms which inevitably present themselves upon the introduction of those increments; purged, in addition, also of all that goes with them, of the formal categories, above all of that of the infinite, of the infinite approximation, and likewise of the here still empty categories of continuous magnitudel which, like striving, becoming, occasion of a variation, are otherwise deemed necessary.
