The economic process is **always the current**, **purely-dynamic**, concrete functioning. The analysis of the dynamic process is always relevant to the **present fact**. The **immanent intelligibility** of such a dynamic, **ever-varying process** may** itself be an invariant; **i.e. though the differentials may change in magnitude, the relation of the **differential velocities and accelerations** among themselves is **invariant**. So it is in the case of dynamic pendular motion, elliptic motion, the variables of electromagnetic phenomena, and in the dynamic economic process. The **general laws** of the process are **applicable in any instance**. These **primary, abstract, general, field-theoretic laws** may be applied to whatever may be the **secondary determinations** from **the concrete non-systematic manifold. **Thus we can get the **particular law** explaining the **particular** **concrete process** under investigation.

The overall **economic** **functioning** has an **objective immanent intelligibility**. This intelligibility is an **invariant** – a set of **differential equations** which **implicitly define** the explanatory, conjugate, differentials of the dynamic process. The **explanatory terms are abstract functions** defined by their **functional relations to one another**. In the implicit equations, the **terms define the relations and the relations define the terms**, and **insight** fixes both. And the equations **cohere** with one another to constitute a **fully-explanatory field theory.**

The

point-to-lineand highercorrespondencesare based upon theindeterminacyof the relation between certain (surplus) products and the (later ultimate basic) products that (exit the process and eventually) enter into the standard of living. …the indeterminacy is very much a present fact. One has to await the future to have exact information. And while estimates in the present may be esteemed accurate, the future has no intention of being ruled by them: owners do not junk equipment simply because it has outlasted the most reliable estimates; nor are bankrupts kept in business because their expectations, though mistaken, are proved to have been perfectly reasonable. The analysis that insists on the indeterminacy is the analysis that insists on thepresent fact:estimates and expectations are proofsof thepresent indeterminacyand attempts to get round it; and, to come to the main point, an analysis based on such estimates and expectations can never arrive at acriticismof them; it wouldmove in a vicious circle. It is to avoid that circle that we havedivided the processin terms of indeterminate point-to-line and point-to-surface and higher correspondences. [CWL 15, 27-28]in the long run, and especially in the very long run, such a correlation exists. It is that surplus production is

the acceleratorof basic production. In other words thecorrespondencebetween the two is not a point-to-point but a point-to-line correspondence; … Now such acorrespondence, if it is to be expressednot in terms of expectations of the future but in terms of present fact, is a correspondence ofaccelerator to accelerated. … If the system is to move into a long-term expansion, this movement has to begin with a surplus quantity acceleration: surplus production has not merely to maintain or renew existing capital equipment but has to reach a level at which it turns out new units of production and maintains or renews a greater number of existing units; this givesthe quantity surplus expansion. [CWL 21, 132](there is to be discerned a
