# A System is Developed: The Achievements of Euclid, Newton, Einstein, Mendeleev, and Lonergan

Lonergan’s achievement – like the achievements of Euclid, Newton, and Einsteinwas “to bring together many scattered theorems by setting up a unitary basis that would handle all of them and a great number of others as well.”  Note in the excerpts below these phrases

• a field of greater generality
• an enlarged and radically different field
• scientific generalization
• (analytical) level of system
• organized system
• one single organized subject
• a determinate systematic structure
• a determinate field
• a single explanatory unity
• ultimate premises
• the stability of the sets and patterns of dynamic relationships

Consider:

Generalization comes with Newton, who attacked the general theory of motion, laid down its pure theory, identified Kepler’s and Galileo’s laws by inventing the calculus, and so found himself in a position to account for any corporeal motion known.  Aristotle, Ptolemy, Copernicus, Galilei, and Kepler had all been busy with particular classes of moving bodies.  Newton dealt in the same way with all.  He did so by turning to a field of greater generality, the laws of motion, and by finding a deeper unity in the apparent disparateness of Kepler’s ellipse and Galilei’s time squared. … Similarly the non-Euclidean geometers and Einstein went beyond Euclid and Newton. … The non-Euclideans moved geometry back to premises more remote than Euclid’s axioms, they developed methods of their own quite unlike Euclid’s, and though they did not impugn Euclid’s theorems, neither were they very interested in them; casually and incidentally they turn them up as particular cases in an enlarged and radically different field. … Einstein went beyond Newton by employing the new geometries to make time an independent variable; and as Newton transformed the formulation and interpretation of Kepler’s laws, so Einstein transforms the Newtonian laws of motion. … It is, we believe, a scientific generalization of the old political economy and of modern economics that will yield the new political economy which we need. … Plainly the way out is through a more general field.

# A Philip McShane Sampler Relevant to Functional Macroeconomic Dynamics

Philip McShane had a strong background in thus he was able to understand the scientific significance of Bernard Lonergan’s macroeconomic field theory in an Einsteinian context. (See Philip McShane in Categories in the right sidebar)

First we display, in brief, key excerpts, many of which contain analogies from physics and chemistry, relevant to the science of Functional Macroeconomic Dynamics; then we show the same excerpts more fully within lengthier quotes. Continue reading

# Lonergan’s “Macroeconomic Field Theory” (MFT), AKA “Functional Macroeconomic Dynamics” (FMD)

Functional Macroeconomic Dynamics seeks not merely to “view” and describe the economic process; rather it seeks to understand and explain the process in order to provide norms of adaptation and systematic guidance to managers of the process(Continue reading)

# Scientific Generalization by Functional Analysis of the Network of Interdependent Rates

The non-Euclideans moved geometry back to premises more remote than Euclid’s axioms, they developed methods of their own quite unlike Euclid’s, and though they did not impugn Euclid’s theorems, neither were they very interested in them; casually and incidentally they turn them up as particular cases in an enlarged and radically different field.

# The Labor Theory of Value Debunked

Macroeconomists must grasp the difference between economic value and exchange value.

the exchange solution is a dynamic equilibrium resting on the equilibria of markets. … every product of the exchange economy must mate through exchange with some other product, and the ratio in which the two mate is the exchange value.  The generality of this equilibrium makes it indifferent to endless complexity and endless change; for it stands on a level above all particular products and all particular modes of production.  (CWL 21, 34-35)

…  Adam Smith and all the proponents of the “labor” theory of value were never able to clarify the relationship between exchange value and “toil and trouble” as the measure of value.  Lonergan shifted the issue entirely by explaining that an “economic value relates an object to human effort, but an exchange value relates objects among themselves.”31 (CWL 21, 31) [Fred Lawrence; “Money, Institutions, and The Human Good,” in Liddy, 2010, 183-84]

… , like Smith, Locke, Ricardo, and Marx later on, Aristotle did not seem to understand money in terms of exchange value, and therefore as relating objects among themselves in relation to the concomitance or lack of concomitance between “the real flow of property, goods, and services and the dummy flow being given and taken in exchange for the real flow.”39 CWL 21, 40 Still less did they grasp that in an advanced industrial society, the real flow and the money flow are channeled within two separate circuits of production and circulation functionally distinguished into producer goods and consumer goods, and operating in real time in accord with distinct phases of expansion.  Besides misunderstanding money of account, they misunderstood the relationship of money to time.

# Theoretical Breakthroughs of Euclid, Newton, Hilbert, Einstein, and Lonergan

To help the reader gain an appreciation of Lonergan’s achievement of Modern Macroeconomic Field Theory we will, in each section, print leading excerpts, then highlight the key concepts of those excerpts. We will comment on the historically-significant advances in geometry of Euclid and Hilbert, in physics of Newton and Einstein, and in macroeconomics of Lonergan.

• Euclid’s great achievement was his rigorous deduction of geometry.
• Hilbert’s great achievement was his employment of implicit definition to reorder Euclid’s geometry.
• Newton’s two great achievements were unifying the isolated insights of Galileo and Kepler into a unified system of mechanics and his invention of the calculus.
• One of the great achievements of Einstein was the invention of the field theories of Special Relativity, General Relativity, and Gravitation.
• One of Lonergan’s several great achievements was his systematization of macroeconomic phenomena in his Modern Macroeconomic Field Theory. He combined the technique of implicit definition introduced by Hilbert and the concept of a field theory developed by Faraday and Einstein; and he developed an explanatory macroeconomics, which is general, invariant, and relevant in any instance.

# Lonergan’s Laws of Economic Motion

Newton’s Laws of Motion are laws of efficient cause.  In brief:

• A body at rest or in uniform motion remains at rest or in uniform motion unless acted upon by an(external, efficient-causal) force
• F = ma; force equals mass times acceleration
• When one object exerts a force on a second object, the second exerts an equal and oppositely directed force of equal magnitude on the first. (Continue reading)
