A quotient of differentials is indeed calculable if it is a matter of the limit of variation of the production flows from the viewpoint of a full output, but it is not calculable if it is a matter of the production flow and the labour flow on which surplus value depends. Thus the difference is not canceled in the relationship that constitutes it as a difference in nature; the "tendency" has no end, it has no exterior limit that it could reach or even approximate. The tendency's only limit is internal, and it is continually going beyond it, but by displacing this limit--that is, by reconstituting it, be rediscovering it as an internal limit to be surpassed again by means of a displacement; thus, the continuity of the capitalist process engenders itself in this break of a break that is always displaced, in this unity of the schiz and the flow. In this respect already the field of social immanence, as revealed under the withdrawal and the transformation of the Urstaat, is continually expanding, and acquires a consistency entirely its own, which shows the manner in which capitalism for its part was able to interpret the general principle according to which things work well only providing they break down, crises being "the means immanent to the capitalist mode of production."
