Here is a first draft of a section of a new book I am starting:
Marshall was not the first to advocate a more rigorous analysis of the
economy. However, nobody before Marshall ever matched his obsession
with reconstituting academic political economy as the supposedly
scientific discipline of economics.
Marshall's project of recasting economics as a science grew out of his
deep resentment of the fact that anybody could pretend to be competent
to recommend policy decisions based on political regardless of
academic training. This problem came to a head in 1869, after William
Gladstone, by virtue of his position as Prime Minister, appointed Sir
John Robert Seeley to the Regius Professorship in Modern History.
In his Inaugural Lecture, Seeley emphasized the policy role of the
chair, convinced that political economy fell within the scope of his
discipline of history (Groenewegen 1995, p. 129). At first, Marshall
embraced Seeley's vision, immersing himself in historical research. By
1885, when Marshall gave his own Inaugural Lecture at Cambridge, he had
undergone a conversion (Marshall 1885).
By then, Marshall had become disdainful of the historical method. Only
with the guidance of economic theory could any sense be made of
historical knowledge. Marshall was appalled that people without
training in economics. How could a mere historian aspire to speak about
weighty matters of political economy?
... facts by themselves are silent.
Observation discovers nothing directly of the actions of causes, but
only of sequences in time. It may find that an event followed on, or
that it coincided with, a certain group of other events. But this gives
no guidance ....
Experience in controversies ... brings out the impossibility of
learning anything from facts till they are examined and interpreted by
reason; and teaches that the most reckless and treacherous of all
theorists is he who professes to let facts and figures speak for
themselves, who keeps in the background the part he has played, perhaps
unconsciously, in selecting and grouping them, and in suggesting the
argument post hoc ergo propter hoc. [Marshall 1885, pp. 167 68]
Greedy then as the economists must be for facts, he must not be content
with mere facts .... He will thus work in light of facts, but the light
will not be thrown directly, it will be reflected and concentrated by
science. [Marshall 1885, p. 171]
According to one student of Marshall's career, his "first and paramount
objective" was that ... economists ... be trained in a body of knowledge
which without excessive grief he recognised would be inaccessible
to laymen" (Maloney 1985, pp. 3 and 2). These economic specialists "who
announced their monopoly of occupational competence" were able to
"secure, on the basis of their claims, the right to decide whom to train
and not to train for the occupation, and in what to train them" (Maloney
1985, p. 4).
To make political economy seem more scientific, Marshall, who was born
a year after Jane Austen wrote about her non academic economists,
Marshall began using the term, "economics," in part because it suggested
an affinity with physics. Marshall was not the first economist to use
the term, "economics," in the title of a major treatise. Authors of
lesser known works, such as those of J. M. Sturtevant (1877) and H. D.
Macleod (1878), preceded him in that respect (see Arndt 1984), but their
works had little impact. In contrast, Marshall was largely responsible
for renaming the subject.
Once economics became inaccessible to ordinary people only those who
had undergone formal training in economics the priesthood of
economics could communicate the truths of the discipline to the
unwashed masses. The underlying basis of such truths was of no concern
to ordinary people, who were expected to take the world of the
economists on faith.
To make matters worse, Marshall made another move. In addition to
changing "economy" to "economics," he removed the "political" from
"political economy." Marshall and his wife, Mary, writing in their
Economics of Industry, explained that their motive: "... political
interests generally mean the interest of some part or parts of the
nation" rather than the nation as a whole (Marshall and Marshall 1879,
p. 2). Economics, in contrast, was above the world of political
interests, standing as the true science of making decisions in the best
interest of everybody. Anybody who questioned economists'
pronouncements could be presumed to have some nefarious motives.
Unfortunately, the notion of excluding the political from political
economy was disingenuous. In the early world of academic economics, the
meaning of politics became distorted to mean anything that challenged
the prevailing economic interests. As a result, the politics of the
status quo remained protected, hidden from view under a cloak of
pretended objectivity. In this way, economists could pride themselves
on the virtue of their scientific approach, while allowing those with
money and power to generally remain immune from any critical analysis.
The scientific pretensions of economics hobbled the discipline even
further, once economists attempted to emulate natural sciences by making
their work ever more mathematical. Over time, the increasing extent of
abstraction in economic theory created a widening gulf between academic
economics and the real world. All too often, what remained was a
brilliant, but sterile display of virtuosity that could win the acclaim
of fellow economists.
Alfred Marshall may have realized the damage that he had done. He said
to his wife, shortly before his death, after dinner on Christmas Day
1923: "If I had to live my life over again, I should have devoted it to
Psychology. Economics has too little to do with ideals" (Groenewegen
1995, p. 729). But the damage had already been done.
