Notes Re Reading Graphs In CWL 15, pp. 121-25

In the graphs of CWL 15, pages 121-25, it is easy to become disoriented by the symbols on the vertical axes and by the titles and annotations.  In particular, one might tend mistakenly to view Q as a symbol for an absolute quantity or an accumulation rather than for a rate of flow of a quantity.  Recall:

In Lonergan’s circulation analysis, the basic terms are ratesrates of productive activities and rates of payments.  The objective of the analysis is to discover the underlying intelligible and dynamic (accelerative) network of functional, mutually conditioning, and interdependent relationships of these rates to one another.  [CWL 15  26-27  ftnt 27]

Lonergan never used terms for magnitudes, only for rates and their accelerations (‘rates of rates’) in the Essay in Circulation Analysis.  [CWL 15, 182]

But if the ultimate product qi is related by a double summation to the contributions of factors of production qijk, then the total flow of ultimate products Qi is also related by a double summation to the rates of the contributions of the factors of production Qijk, where both Qiand Qijk are instances of the form so much or so many every so often.’  (CWL 15, 30)

In the graphs superscripts identify basic (‘) or surplus (“) elements.  Absence of superscripts here indicates “in any case.”
