## .1. **Introductory**

In his scholarly ** Revolution in Science **[Cohen, 1985]

**,**I. Bernard Cohen traced how both the Faraday-Maxwell-Hertz

**Electromagnetic Field Theory**and Einstein’s

**Special Relativity Field Theory**came to be appreciated as

**revolutionary**,

**though the appreciation was not immediate**. Critical to the two theories’ gaining popularity was, first, the

**recognition**of their revolutionary

**scientific significance by brilliant and eminent scientists;**second, the

**verification of the hypotheses**by experimental scientists; and finally the

**conversion**

**of the physicist community**at large to their

**new ways of thinking about the world**. In the Faraday-Maxwell case it was Heinrich Hertz’s experiments which made the critical difference; and in Einstein’s case it was first and chiefly Max Planck, then Max von Laue, Max Born, Hermann Minkowski, and astronomer Arthur Eddington. Planck was the first to understand Special Relativity’s scientific significance and Eddington became “the chief agent for dissemination and acceptance of Einstein’s ideas.”

**[Cohen, 1985, 416]**

Similarly, the **revolutionary significance** of Bernard Lonergan’s **Macroeconomic Field Theory** was first grasped by Philip McShane, a theoretical physicist and philosopher, and by Peter Burley, a brilliant economist, and now it awaits further understanding and econometric verification by colleagues in **academia**, the **Bureau of Economic Analysis**, and/or the **Federal Reserve Bank**.

**.2. The Need For Brilliant Colleagues; Discovery, Appreciation, Communication, and Empirical Verification**

The general acceptance of a new and better theory requires several brilliant, respected colleagues to deliver the good news. A widespread acceptance often takes time — as it did in the case of Faraday-Maxwell-Hertz’s electromagnetic theory and Einstein’s special relativity.

We quote from I. Bernard Cohen’s ** Revolution in Science. **Here is a copy of the back cover:

**Re Faraday-Maxwell-Hertz:**

Maxwell’sideas were developed in a series of papers dated1855-1856. 1861-1862, 1864, and 1865 and were given a more or less final form in hisTreatise on Electricity and Magnetismin 1873. But for some years thereafter, this revolutionary new doctrine remained no more than a revolution on paper and did not become a revolution in science until the work ofHeinrich Hertzin the years up to1888. For this reason, the revolution is sometimes known as theFaraday-Maxwell-Hertzrevolution.[Cohen, 1985, 303]So, we may understand the importance of the experiments of

Heinrich Hertz, conducted in the years up to1888, whichultimately confirmedthe predictions of Maxwell’s theory. Hertz not only produced electromagnetic waves and found their speed (by measuring the wavelength of standing waves of known frequency): he showed that these waves were like light in the properties ofreflection, refraction, and polarization, and that they could be focused.[Cohen, 1985, 305-6]Maxwell’s theory was difficult to accept for a number of reasons. First, it was

conceptually new, withradical notionssuch as the ‘displacement current’. Second, Maxwell presented the theory not merely as a mathematical elaboration of new principles but in terms of physical models.[Cohen, 1985, 306]

Hertz’scontribution was not merely to devise and to execute a clever experiment, great as that achievement was, He showed also how his experiments were significant as the“first demonstration of the finite propagation of a supposed action at a distance.”(McCormmach 1972, 345) .[Cohen, 1985, 306]

Poincareexplained how Hertz’s experiments provided the ‘experimentum crucis’ between Maxwell’s theories and its rival.[Cohen, 1985, 307-8]In any event, later experiments (first by

Sarasinandde la Rive) proved conclusively that Maxwell’s theory was correct. Thismarked the endof theories based on instantaneous action at a distance, and the beginning of a general acceptance offield theoriesin the Maxwellian mode, with finite speed of propagation equal to that of light.[Cohen, 1985, 308]

**Re Einstein:**

Einsteinproposed thespecial theory of relativityin1905, in a paper published in theAnnalen der Physik.It was followed by a supplement in that same year in which the first form of themass-energy equivalencewas stated for radiation. In 1907, Einstein put forth a comprehensive paper on relativity , containing the general resultE = mc. His radical paper set forth^{2}new conceptsof mass, space, and time and challenged the apparently simple notion of simultaneity.[Cohen, 1985, 406]

Einstein’s theory was met with **“icy criticism.”**

Einstein, according to the recollections of his sister (Pais 1982, 150-51),”imagined that his publication in the renowned and much-read journal would draw immediate attention.” Of course, he anticipated “sharp opposition and the severest criticism,” but he was “very disappointed” by the lack of response, the“icy criticism.”In time he received a letter fromMax Planckasking questions on some obscure points in the paper which was the cause of “especially great” joy sincePlanckwas“one of the greatest physicists of that time.”Planck’s early and deep commitment to relativity was amajor reason for the very rapid spread of interestin the new topic among physicists (Pais ibid.). In the year following the publication of Einstein’s paper,Planck began to lectureon the theory of relativity in Berlin, not on Einstein’s presentation but on Laurentz’s theory of the electron.[Cohen, 1985, 406]

Others then followed **Planck’s** lead.

Planck’s assistant,

Max von Laue(later a Nobel Prize winner in physics), published a paper on relativity in 1907. … Von Laue went to Berne as a skeptic to visit Einstein and found it hard to believe that this “young man” could be the “father of the relativity theory.”[Cohen, 1985, 407]“

Max Bornrecognized its greatness and also the necessity for formal generalizations.” It was Infeld’s judgment that Born’s own work on relativity theory, produced much later, “became one of the important early contributions to this field of science.”[Cohen, 1985, 407]In the following year, 1908,

Hermann Minkowskipublished a radical transformation of of Einstein’s theory into mathematical form, beginning the “enormous formal simplification of special relativity.” (Pais 1982, 152) By these stages, the revolution on paper was becominga revolution in science. Pais (1982, 152) dates the rapid growth of Einstein’s reputation and influence from 1908.[Cohen, 1985, 408]While this experimental evidence was coming in, the theory itself was undergoing a

fundamental reconstructionat the hands ofHermann Minkowski. … in 1908 Minkowski published a paper introducing the concept of a singlefour-dimensional ‘‘space-time’to replace the separate conceptual entities of three-dimensional space and one-dimensional time. He also gave relativity theory its modern tensor form. … introduced new technical terms into relativity, and made it evident from the point of view of relativity that the traditional Newtonian theory of gravitation was not adequate (Pais 1982, 152)[Cohen, 1985, 409]

Max Born’sdiscussion of his first reading experience of Einstein’s papers reminds us how difficult the Einsteinian conception was, even for those who had no problem with the mathematics. In 1907, when Loria directed him to Einstein’s publications, Born had been a member of of Hermann Minkowski’s university seminar, and so –- he writes (1969, 104-105) -– “quite familiar with relativistic ideas [presumably Lorentz’s] and the Lorentz transformations.” Even so, he recalled, when he read Einstein’s papers,“Einstein’s reasoning was a revelationto me.” As anintellectual creation, Born found that “Einstein’s theory wasnew and revolutionary.” Einstein’s presentation had “the audacity of challenging Isaac Newton’s established philosophy, the traditional concepts of space and time. In retrospect Born recognized the force of Einstein’s intellectual revolution and the revolution on paper, but he saw clearly that there wasnot yet a revolution in the sciences..… … …Einstein’s theory was in fact radical – so“new and revolutionary,”he wrote much later – thatan effort was needed to assimilate it.” … … …The Einsteinian revolution in sciencerequired a general acceptanceof Einstein’sfundamentallynew way of dealing with the physical world.[Cohen, 1985, 410-11]By about

1911Einstein’s special theory of relativity had gained enough adherents to constitute a revolution in science. In that year,Arnold Sommerfeldannounced that the theory of relativity was “already so well established that it was no longer on the frontiers of physics.” (Miller 1981, 257) Early in 1912Wilhelm Wien, winner of the Nobel Prize in physics for 1911, proposed that Einstein and Lorentz be awarded the coveted prize. From a “logical point of view,” he wrote (quoted in Pais 1982, 153), the principle of relativity “must be considered asone of the most significant accomplishments ever achieved in theoretical physics.” There was now, he said, clear “confirmation of the theory by experiment.”Lorentz, he concluded was the first to find “the mathematical content of the relativity principle,” but Einstein “succeeded in reducing it to a simple principle.”[Cohen, 1985, 412]The new theory led to

threetestablepredictions. The first was the advance of the perihelion of the planet Mercury, the phenomenon … … … The second prediction was that light should be bent in a gravitational field. … … … The third prediction was what is known as the “red shift” of spectral lines that are part of the stellar radiation … … … Here werethree tests that could be made of the theory.[Cohen, 1985, 415-16]The English astronomer

Arthur Eddington… becamethe chief agent for dissemination and acceptance of Einstein’s ideas.…P. A. M. Dirachas recorded, as one example, how he first learned of relativity, … by reading Eddington. Even more important, immediately after the succession of hostilities, Eddington in 1919 organized a British eclipse expedition to test the predicted bending of light during a total eclipse of the sun. The confirmatory result electrified scientists and non-scientists alike all over the world.[Cohen, 1985, 416]It is difficult to recapture today the scientific excitement of

1919. … In the autumn of 1919 the data had been analyzed and on 6 November 1919, at a joint meeting of the royal Astronomical Society and the Royal Society, the Astronomer Royal announced that “light is deflected in accordance with Einstein’s law of gravitation. …J. J. Thomsonwas in the chair and declared this to be“the most important result”in relation to “the theory of gravitation since Newton’s day, ”the highest achievement of human thought.” … On November 8, theTimesran a second article on revolution, this one headed “The Revolution in science”: “Einstein vs. Newton,” ”Views of Eminent Physicists.” …H. A. Lorentzpublished an article in a Rotterdam newspaper on 19 November, which was at once translated and printed in theNew York Times.… on 14 December. Einstein’s picture appeared on the cover of the weeklyBerliner Illustrierte Zeitung, with a caption which declared not only that Einstein has made“a complete revolution in our concepts of nature”but that he had producedinsightscomparable to those ofCopernicus, Kepler, and Newton(Pais 1982, 308). On 4 December inNature, E. Cunningham wrote that Einstein’s thought was revolutionary.”[Cohen, 1985, 416-17]

**.3. Propagations in a “Field”**

Acknowledging that electromagnetics and economics are distinct **field theories** involving propagations at very different speeds, we nevertheless wish to strike some comparisons to emphasize to economists the ideas of a) fields and field theory, and b) propagation at a speed.

**scientific field: ***n*: a region or space in which a **given verifiable, objective effect** (such as magnetism or economic acceleration) **exists**

**field theory: ***n*: a theory of the **invariant** **relations** of **explanatory conjugates** **among themselves** rather than to an external force or other external element.

** ****propagate**: *vb*: to transmit (as waves of sound or light and surges of economic advancement) through a medium, including a “field”); *vi* to travel through space or a material or a field – often used of wave energy (such as light, sound, audio waves, or economic surges)

**Michael Faraday** developed the idea of a set of coherent, explanatory relations verified as “**existent**” and **explanatory**, and comprising what may be called a distinct **“field” of relations**. The Faraday-Maxwell electromagnetic field-theoretic **hypothesis** and Hertz’s experimental **verification** **of that hypothesis** resulted in the replacement of the idea of **instantaneous action at a distance** by the idea of a **field **constituted by the **propagation** of electromagnetic waves at a **finite** speed. Previous isolated insights into the static and dynamic magnetic and electric fields were finally **unified** into a single coherent set of equations explaining electromagnetic phenomena.** **The **immanent intelligibility** of the static and dynamic phenomena was formulated in Maxwell’s equations in which all phenomena are **understood as** **interrelated and** **solidary** with one another.

Certainly

Faraday’s contributionwas of tremendous importance, including the significant conception that a magnetic field is composed of lines of force, as well as theextraordinary insightthat electrical and magnetic actions arenot transmitted instantaneouslybutrequire time.[Cohen, 1985, 302]Furthermore,

Maxwell, a pioneer in dimensional analysis, showed that the factor linking two systems of electrical units, electrostatic and electromagnetic, was avelocityand in fact had a numerical very close tothe velocity of light.[Cohen, 1985, 305]

Hertz’scontribution was not merely to devise and to execute a clever experiment, great as that achievement was. He showed also how his experiments were significant as the“first demonstration of the finite propagation of a supposed action at a distance.”(McCormmach 1972, 345) .[Cohen, 1985, 306]

… , later experiments (first bySarasinandde la Rive) proved conclusively that Maxwell’s theory was correct. Thismarked the end of theories based on instantaneous action at a distance, and the beginning of a general acceptance offield theoriesin the Maxwellian mode, withfinite speedof propagation equal to that of light.[Cohen, 1985, 308]

Similarly, textbook Walrasian Macrostatics is destined eventually to be **replaced** by Lonergan’s **Macroeconomic Field Theory of the propagation at a speed **of initial incremental point-to-line productive velocities into later accelerations of point-to-point production activities. The verified propagation of effects constitutes the intelligibility of, and the very **existence** of, the **double-circuited** **macroeconomic field**. Mere macrostatics, on the other hand, — with its trappings of separated graphs of shifting curves — suggests a dynamics, but **fails to be a science ****explaining completely** the **dynamic propagation** at a finite speed of incremental point-to-line velocities propagated into point-to-point accelerations. As an electric current induces **solidarily** a magnetic intensity, or a varying magnetic intensity effects **solidarily** an electric intensity, so we say that incremental point-to-line activities “induce” a point-to-point acceleration in the “macroeconomic field.”

See on this website:

- Explanatory Macroeconomic Dynamics; Relevant in Any Instance
- Field Theory in Physics and Macroeconomics,
- A Comparative Note on Einstein’s Special-Relativity Field Theory and Lonergan’s Macroeconomic Field Theory, and
- Theoretical Breakthroughs of Euclid, Hilbert, Einstein, and Lonergan.

Right at the start Lonergan makes **precise analytic distinctions** between point-to-point vs. point-to-line velocities and formulates their propagational relations; and, upon these “**foundational**” interrelations, he builds a **superstructure** of relations comprising an **explanation** – not a mere description – of the objective economic process. With the combination of the **field-theoretic** **relations **with **concrete determinations** occurring in the non-systematic probabilistic seriation of economic events, Macroeconomic Field Theory connects and formalizes a) the **velocitous invention** and installation of new and better machines and methods, — aided as needed by **credit to bridge the gap in time** between payments made and payments received — , b) the thus **temporal propagation** of expansion of basic production and sale, which sets the stage for c) the resulting development of **greater** **leisure and higher culture**.

Macroeconomic Field Theory is the **general immanent intelligibility,** in the form of a lagged technical expansion, of a system of “propagation” or “transmission” of improvements in the economic process. MFT is a coherent and comprehensive **system** of **abstract, purely-dynamic, purely-relational equations**. It is a **normative theory** explaining both dynamic equilibrium and dynamic disequilibrium. This theory explains the conditions of **continuity**, **equilibrium** and the **equilibrated propagation of higher productivity through phases** of a **normative pure cycle** of expansion. Just as electromagnetics is a **field** **theory of the propagational interrelations** of electric and magnetic phenomena **among** **themselves**, so Lonergan’s Monetary Field Theory is **a field theory of propagational relations **between point-to-line (“surplus”)and point-to-point (“basic”) phenomena in the macroeconomic field. The theory’s **differential equations** of velocity and acceleration specify and explain the economic field in which humans interact.

In Lonergan’s Macroeconomic Field Theory, the concepts and the conditions of **concomitance, continuity, and equilibrium** — present as **vital normativities** throughout the “somewhat-fluid” process of **phased expansion** — constitute the **normativity** mandated by the Diagram of Rates of Flow **below on the left**. The concepts of gradient, curvature, divergence, curl, probability and possible deviation from the ideal gestation of capital and the propagation of acceleration are embedded in the diagrams **below on the right**. (Click here)

The economic process – like the oscillation of a pendulum, the parabola of a missile, the elliptical motion of a planet – is a **concrete process**. Because the economic process is a **concrete** system of interconnected **dynamical** flows of goods and payments, the basic terms of Functional Macroeconomic Dynamics are **interrelated, interdependent velocities** and their changes. And, again, the process is constituted by a **finite** **propagation** unto states of greater “kinetic economic energy” from the invention and investment in new and better capital through to the acceleration of basic, more bounteous production. The **propagation** is stated in general terms in the lagged technical accelerator. (CWL 15, 37)

*k*,In the macroeconomics of the concrete process there is **no instantaneous** action at a distance. **Propagation is at a finite speed**. The horizontal axes in the right columns above represent Galilean time and its passage.

**Clerk-Maxwell’s** velocity of propagation **in empty space** of electromagnetic phenomena was the **finite** speed of light. And Einstein, in his treatment of relative velocities, needed to redefine time as a relativistic fourth variable in a 4-dimensional space-time with the symbol ** ict**. Functional Macroeconomic Dynamics’ time can be regarded as simple Galilean time. And expansion takes a lot of it. In addition, of course, the actual process conducted by

**unenlightened**, self-interested, often feckless households and firms exhibits neither the rigidities nor the speed of electromagnetic and gravitational phenomena. Though the economic process has

**invariant, universally-applicable**field-theoretic

**norms**of

**continuity**,

**equilibrium**and

**sectoral**

**intensities**for realization of conceived potential, because that actual economic process is operated by mistake-making and macroeconomically ignorant humans, there are possibilities of deviations from the

**norms**of path and speed in the

**ideal pure phased cycle**. There may be effected excess investment and premature maxima in the surplus productive process, and a failure, or at least too-long delay, in the propagation of the acceleration of the basic process. These non-normative occurrences can be

**explained**by the

**mathematics**of such as restorative force, variable pressure, ideal frequency and probability distributions, and standard deviations, rather than merely unscientifically described in everyday jargon as “booms” and “slumps”. The economic expansion, despite an exigence for normative realization, does not enjoy the rigidity of, say, ideal waveform motion at the speed of light. And the actual propagation effected through Galilean space and time by efficient-causal, “forceful” combinations of motivated mind and muscle, skills, methods, materials, machines, warehousing and transport is not instantaneous. Even a perfectly-executed normative expansion takes time

**(**

*t-a*).Functional Macroeconomic Dynamics, also called Monetary Field Theory, is a **general theory** of circuit acceleration.

… thegeneral theory of circuit accelerationis that it takes place in a constrained and limited way when quantities of money in the circuits are constant, but without let or hindrance (but not necessarily an instantaneous runaway) when quantities of money are variable. Finally, provided (D’-s’I’), (D”-s”I”), G vary only slightly from zero, so that their action is absorbed by stocks of goods at the final markets, they exercise a stimulating effect in favor of positive or negative circuit acceleration; otherwise their action pertains either tosuperimposed circuitsof favorable balances of foreign trade and deficit government spending, or else to the cyclic phenomena of booms and slumps. (CWL 15, 64-65)once long-term acceleration is underway, rates of production

increase increasingly; their graphs areconcave upward; but thecurvaturemoves from being flatter to being rounder as the acceleration is generalized from one section (of the capital sector) to another throughout the productive process. During this period of generalization, rates of production are not merely increasing ingeometrical progressionbut movingfrom less to more rapid geometrical progressions.… This situation, however, is bound to be temporary;its existence is the lagbetween the generalized long-term acceleration of the surplus stage and that of the basic stage. When that is overcome, dQ’/Q’ moves again to a peak and remains there; and by the same token, dQ”/Q” will begin to decline. (CWL 15, 126)Technology advances over time. To take a single example, it yields the cotton gins for cleaning raw cotton, the spindles for spinning it into thread, the looms for making the thread into cloth, and the sewing machines that change cloth into clothing. (CWL 15, 76)

Extraction machinery coal; iron ore

Blast furnaces pig iron

Steel mills steel

Machine tools gins, spindles, looms, sewing machines

(CWL 15, 22)

There are three reasons for expecting a long-term acceleration to be a massive affair. … 1) long term planning … 2) as the increased demand for one (unit) justifies development in a series of productive units, so the increased demand for many justifies development in a series of series of units … 3) There is a third consideration of a **more abstract character**. The emergence both of new ideas and of the concrete conditions necessary for their practical implementation forms **matrices of interdependence**: any objective change gives rise to **a series of new possibilities** and the realization of any of these possibilities has similar consequences; but not all changes are equally pregnant, so that economic history is a succession of time periods in which alternatively the conditions for great change are being slowly accumulated and, later, the great changes themselves are being brought to birth. (CWL 15, 36)

** ****.4. A Revolutionary Way of Understanding the World**

We avoid arguing about the concepts and meanings of ** revolution vs. evolution**. We simply want to point out radical changes – whether properly called revolutions or evolutions – of

**ways of understanding phenomena**in Electromagnetics, Special Relativity and Macroeconomics. We wish the reader to view and understand

**Lonergan’s Macroeconomic Field Theory**as a radically new systematics of the objective economic process, as radically new as once were Electromagnetics and Special Relativity.

Faraday and Maxwell were concerned with understanding the two static and dynamic phenomena of electricity and magnetism, and they found a new way of understanding them as **solidary with one another** as formalized in Maxwell’s set of coherent equations comprising Electromagnetic Field Theory. Lonergan, likewise, sought to understand the system of two or more monetary circuits expansionary macroeconomics; and he found the **explanation** in his set of coherent equations which we call Macroeconomic Field Theory.

Our subtitle is **A Revolutionary Way of Understanding the World. **Phrases **relevant to this idea** include:

**Re Faraday-Maxwell-Hertz Electromagnetic Field Theory**

- a
**classical transformation**of scientific ideas - (resulting in) a
**wholly new idea** **one of the greatest triumphs of human intellectual endeavor**- the
**field**of a force**has “an independent physical existence**” - marked

**based “ultimately**on two great pillars,” of which one is “special relativity,” - general relativity implied
**the essential falsity or inadequacy**of one of the most successful theories physics had ever produced

**We display excerpts from Cohen’s Revolution in Science re Electromagnetics :**

Here we may see the ingredients of a

classical transformationof scientific ideas, resulting in awholly new idea, that electricity may be “disseminated through space” and need not necessarily be only “a fluid confined to conductors.” … … … Maxwell conveyed the extraordinary quality of his result by using italic type. We “can scarcely avoid the inference,” he wrote (1890,I: 500), “that light consists inthe transverse undulations of the same medium which is the cause of electric and magnetic phenomena.”[Cohen, 1985, 304],

“since thenevery optical phenomenon can be directly treated as an electromagnetic problem.” For Planck, this must “remain for all time” one of “the greatest triumphs of human intellectual endeavor.”[Cohen, 1985, 305],The Faraday-Maxwell conception that there can be no such “immediate action at a distance,” and that

the field of a forcehas “an independent physical existence” wasso strange and difficult to comprehendthat the new theory, according toPlanck, “found no foothold in Germany and was scarcely even noticed.”[Cohen, 1985, 307]

Thismarked the end of theoriesbased on instantaneous action at a distance, and the beginning of ageneral acceptance of field theoriesin the Maxwellian mode, withfinite speed of propagationequal to that of light.[Cohen, 1985, 308]

In a lecture given in1888, the year in which Hertz sent to Helmholtz his final results of his experiments on electric waves,Helmholtz(1907, 3) spoke of a“complete revolution” (“eine vollstandige Umwalzung”) that the”Faraday-Maxwellian ideas” had brought about in theoretical physics (”the theoretical physics of the aether”).[Cohen, 1985, 308]

“Maxwell hadreversed the natural orderaccording to which theoretical physics evolves;[Cohen, 1985, 309]

** And we display excerpts from ****Cohen’s Revolution in Science re Special Relativity**

Loria’s teacher, “Professor

Witkowskiin Crakow (and a very great teacher he was),” read Einstein’s 1905 paper on relativity and “exclaimed to Loria, ‘A new Copernicus has been born!Read Einstein’s paper..’” “It turned out that neither Born nor anyone else there had heard about Einstein.” According to Infeld’s story, they then “went to the library, took from the bookshelves the seventeenth volume ofAnnalen der Physikand started to read Einstein’s article.” Immediately, says Infeld, “Max Bornrecognized its greatness and also the necessity for formal generalizations.” It was Infeld’s judgment that Born’s own work on relativity theory, produced much later, “became one of the important early contributions to this field of science.”[Cohen, 1985, 407]Both Maxwell’s system of electromagnetic equations and Einstein’s redefinition of spacetime were

fundamentallynew ways of dealing with the physical world.[Cohen, 1985, 410-11].By about

1911Einstein’s special theory of relativity had gained enough adherents to constitute arevolution in science. … … … From a logical point of view (Wilhelm Wien) wrote (quoted in Pais 1982, 153) the principle of relativity “must be considered as one of the most significant accomplishments ever achieved in theoretical physics.” There was now, he said, clear “confirmation of the theory by experiment.” … Einstein “succeeded in reducing relativity to a simple principle.[Cohen, 1985, 412]It has been said that

Einsteindid for the gravitational field what Maxwell had done for the electromagneticfield. One of the intellectually spectacular features of general relativity was to reduce Newtonian gravitational forces to aspects of the curvature of four-dimensional space-time.[Cohen, 1985, 415]

Steven Weinberg(1979, 22) holds that Einstein’s “most remarkable achievement” was that “he for the first time made space and time a part of physics and not of metaphysics.” According to the mathematician Emile Borel (1960, 3), “Einstein has given us not onlya new theory of physicsbut also has taught usa new manner in which to look at the world.” As a result, “it will be impossible for those who have studied his theories to think as they would have thought had they not studied them. … Thus Einstein’s two theories of relativity inaugurated a revolution in philosophy along with a revolution in physics.[Cohen, 1985, 418],

Steven Weinberg(1981-20) has pointed out that “all modern theories of physics that deal with matter at the most fundamental level” arebased “ultimatelyon two great pillars,” of which one is “special relativity,” the other “quantum mechanics.”[Cohen, 1985, 418]

Furthermore, general relativity implied theessential falsity or inadequacyof one of the most successful theories physics had ever produced – the Newtonian theory of gravitation – and the introduction of a strange concept of curvature of four-dimensional space-time to account for gravitational forces.[Cohen, 1985, 419]

And what we call Lonergan’s “**Functional Macroeconomic Dynamics”** or “**Macroeconomic Field Theory”** constitutes

- A
**Copernican revolution**in macroeconomics - A
**revolutionary new****explanation — rather than a mere description —**of the**purely****dynamic**process of the**propagation or****transmission at finite speed**of classes of productive economic energy - A set of aggregate velocities
**implicitly-defined by the relations in which they stand with one another –**as in Hilbert’s geometry - An analysis constructed upon

We print quotes re Lonergan’s Macroeconomic Field Theory as **a new way of looking at and understanding economics.**

Sufficient has been done here (to) provide a basis for

a new paradigmof disequilibrium macrodynamics which, inter alia, responds to Schumpeter’s challenge that, … “has not taken any special cognizance of the process of creative destruction which we have taken to be the essence of capitalism.” (Schumpeter,. P.104) [Burley, 1989, 120-21 ]Capitalism, Socialism, and DemocracyAn analogy may help here. Millenia of alchemy and descriptive chemistry preceded the

breakthroughs of Mendeleev and Meyerin the 1860s. There is nothing obvious about therelational structuringof elements that these two men brought into scientific being.Nor was there a rush to accept it: butnowthe periodic table is part of our culture. That shift in chemistry (the relational structuring of elements) stands out as themajor paradigm shiftin the field. Is something similar possible in economics? [McShane, 2017, 8]Lonergan pointed out that this differentiation of economic activities … is discussed by traditional economists such as S. M. Longfield (1802-1884), John Rae (1796-1872), Nassau Senior (1790-1864), Eugen von Bohm-Bawerk (1851-1914), and in the heavily disputed “Ricardo effect.” But Lonergan credits

Piero Sraffa(1898-1983) as having clarified it most thoroughly in his famous essay,Production of Commodities by Means of Commodities (1960). Yet even Sraffa does not use his sophisticated explanation of the “Ricardo effect” and the “roundabout” or “concertina”-like phenomena associated with it in the way Lonergan does.Lonergan is alonein using this difference in economic activities to specify thesignificant variablesin hisdynamic analysis… no one else considers thefunctionaldistinctionsbetween different kinds of productive rhythmsprior to, andmore fundamental than, wealth, value, supply and demand, price levels and patterns, capital and labor, interest and profits, wages, and so forth….only Lonergananalyzes booms and slumps in terms of how their (explanatory) velocities, accelerations, and decelerations are or are not equilibratedin relation to the events, movements, and changes intwo (or more)distinctmonetary circuits of production and exchange as considered bothin themselves(with circulatory, sequential dependence) andin relation to each otherby means of crossover payments. [CWL 15, Editors’ Introduction, lxii]

“Functional”is for Lonergan atechnicalterm pertaining to the realm ofexplanation, analysis,theory; … Lonergan (identified) the contemporary notion of a“function”as one of the most basic kinds ofexplanatory, implicit definition– one that specifies“things in their relations to one another”… [CWL 15 26-27 ftnt 27]Taking into account past and (expected) future values does not constitute

the creative key transition to dynamics.Those familiar with elementary statics and dynamics will appreciate the shift in thinking involved in passing from (static) equilibrium analysis … to an analysis where attention is focused on second-order differential equations, on d^{2}θ/dt^{2}, d^{2}x/dt^{2}, d^{2}y/dt^{2}, on theprimary relativitiesof a range of related forces, central, friction, whatever. Particularsecondary boundary conditions, past and future pricings and quantities, arerelatively insignificantfor the analysis of theprimary relativity immanent in, and applicable to, every instanceof the process. What is significant is theLeibnitz-Newtonian shift of context. [McShane, 1980, 127]Lonergan illustrates his basic

meaning of ‘explanation’by referring to D. Hilbert’smethod of implicit definition: Let us say, then, that for every basic insight there is a circle of terms and relations, such thatthe terms fix the relations, the relations fix the terms, and the insight fixes both. ‘Thus themeaningof both point and straight line isfixed by the relationthat two and only two points determine a straight line.“ [CWL 15, 26-27 ftnt 27]In Lonergan’s circulation analysis,

the basic terms are rates– rates 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 interdependentrelationships of theserates to one another. [CWL 15 26-27 ftnt 27]

In the **formulation of a dynamic process, velocities **would be** implicitly defined** by their functional relations to one another**;** the relations would define the terms and the terms would define the relations.

The objective principles and laws, which **explain the objective process** would be **independent of the subjective psychology** of the participants and would be cast in a formalism isomorphic with the **intelligibilities immanent in the data** of the **measurable** dynamic flows of the process.

The **explanation** in scientific macroeconomics would yield an **invariant, normative theory**; i.e. a set of **general, invariant, normative** relations **universally applicable**. Though the magnitudes of the variables would change, the relations among the variables would be invariant. (Consider the **variable** magnitudes vs. the **invariant** set of relations in Clerk-Maxwell’s Electromagnetics and in Einstein’s Special Relativity.

… The

analysisthat insists on the indeterminacy is the analysis that insists onthe present fact: estimates and expectations are proofs of 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 would move ina vicious circle. It is to avoid that circle that we have divided the process in terms of indeterminate point-to-line and point-to-surface and higher correspondences. [CWL 15, 28]No doubt

Keyneswasan economist first and a methodologist second… … Lonergan, for his part, is perhapsa methodologist first and an economist second, but, as we shall see, he was able to push his economic reflectionsfurther than Keynesbecause he had a firmer grasp of theessentials of an effective theory. [Gibbons, 1987]

But Functional Macroeconomic Dynamics is **explanatory** rather than **descriptive**. Its basic terms are velocities of **explanatory** functionings. Its terms are classes of velocitous **functional** flows **mutually defined** by the **functional relations** in which they stand with one another. The terms are **purely relational**, and the theory is a **field theory** of explanatory functional relations among ** n **objects. In a system of flows -– such as the flows of products and money — scientific and explanatory analysis is in terms of the

**functional relations**of these flows to one another. Prices, such as those of the IS-LM and AD-AS models, are not the primary analyzand. And

**pretio-quantital**expenditures must be

**interpreted in the light of**the

**functional interrelations**of the explanatory flows which they compose.

as to the notion of cause, Newton conceived of his forces as

efficient causes, and the modern mechanics drops the notion of force; it gets along perfectly well without it. It thinks in terms of afield theory, the set of relationships betweennobjects. The field theory is a set of intelligible relations linkingwhat is implicitly defined by the relations themselves; it is a set of relational forms. The form of any element isknown through its relationsto all other elements. … Field theory is a matter of the immanent intelligibility of the object. (CWL 10, 154)

Paraphrasing(CWL 10, 154)…as to the notion ofcause, macroeconomistsmistakenlyconceive of subjective preferences as elements offormalcauses, and they conceive of changes in subjective preferences asrandomexternal efficient-cause shocks. Explanatory Functional Macroeconomic Dynamics drops the notion of subjective preferences; it gets along perfectly well without it. It makesprecise analytical distinctionsand discoversfunctionalvariables of scientific, explanatory significance. As in Special Relativity, it operates at a deeper point of view and achieves a more profound and general insight. It thinks in terms of afield theory, the set of relationships betweenninterdependent,implicitly-definedfunctional activities. The field theory of Functional Macroeconomic Dynamics is a set of intelligible functional relations linking functionings which are implicitly defined by the relations themselves; it isa set of relational forms. The form of any functioning isknown through its relations to all other functionings. …. Thefield theory of macroeconomic dynamics is a matter of the immanent intelligibility of the objective, dynamic functional process.
