is an irrelevant illustration of one confession that I shall
make, namely, a practitioner sacrifices personal preferences to
meet the convenience of others, if the adjustment is literally
possible and does not involve violation of any basic principle.
A year ago I felt obliged to accept Professor Walker s invita­
tion to deliver a lecture in honor of Professor Wood because
both are close friends and former colleagues. I was instrumental
in bringing Walker to Missouri, and Wood has influenced my

thinking for more than three decades. It seemed altogether
fitting for the University of Missouri to memorialize one of its
greatest scholars with a series of lectures. Frankly, I was flat­
tered to be asked to participate in the celebration, even though
the substance of any memorial is transitory and ephemeral
compared with the lasting influence of the teacher we memori­
alize.
Since Elmer had indicated that he would retire at the end of
the first semester, we agreed on January 10 as the date for the
lecture. I was enthusiastic when he was persuaded to remain
another semester, primarily, to be sure, for the University, but
importantly also because it would enable Mrs. Bopp and me
to visit our daughter Joanna midway between examinations
and the Easter holidays.
Later still, Pinkney asked me to postpone the talk again so
that it might coincide with the celebration of the Fiftieth Anni­
versary of the School of Business and Public Administration.
Whereas I was delighted to make the first change in dates, I
was less happy to make the second. Two considerations induced
me to make it. The first is an abiding attachment to the School.
I dedicated my first book to it in these words: "To the esprit
of the School of Business and Public Administration at the Uni­
versity of Missouri. Unfortunately only those few persons who
are or have been members of its faculty can appreciate this
dedication. But each of the former will know; and each of the
latter will remember —and, remembering, will understand.”
The second circumstance is that the Federal Reserve System
also is celebrating its semicentennial. So, I set aside my personal
preference and appear here today.
Pinkney indicated that the change in time and circumstances
would involve changes in content of the lecture, such as inclu­
sion of some reference to the environment of the School during
my residency as student and teacher from the mid-twenties to
the early forties. I sensed a note of surprise in his voice, how­
ever, when I mentioned an integral facet of that life that I

proposed to recall, because it has no obvious, immediate con­
nection with technical training in either business or public
administration. It is the reading of poetry, especially by David
Halfant, as only he could read poetry in his beautifully modu­
lated monotone. If you are skeptical of that apparently contra­
dictory description of his voice, you may gain some diluted
impression of the discussions that Dave, Russ Bauder, Jay Heinberg, and I, a mere student at the time, used to have. Of course,
each of us specialized in some aspect of business or public ad­
ministration, but fundamentally the horizons of the School were
as unbounded as those of poetry and philosophy.
It is the spirit of adventure into the great unknown future of
mankind that attracted students with uncommitted, inquisitive
minds to the School of Business and Public Administration.
Public evidence of the heroic and unconventional character of
the environment is there for all to see. I mention a single item
to illustrate: DR Scott’s The Cultural Significance of Accounts,
Does that title sound dissonant? It is not: Read the book, now,
decades later, and learn of the kind of germinal yeast to which
we were subjected by Harry Gunnison Brown, J. Harvey
Rogers, and Myron Watkins. To those of us on the inside the
evidence of intellectual ferment was impressive indeed.
When Pinkney sensed the direction in which my inclination
was heading, he quickly established a condition: He allowed
me but a single stanza from one of the poets. I am sure that
those who created that environment would understand why I
finally chose to quote from Eliot's Prufrock rather than from
Dowson s Cynara, or from e.e. cummings’ is five, or from Carl
Sandburg. Here are the words that seem most appropriate to
the occasion:

Come back to tell you all, I shall tell you all” —
If one, settling a pillow by her head,
Should say: "That is not what I meant at all.
That is not it, at all.” 2
Just so, I am not at all sure that my “confession” will turn out
to be what you expected to hear —not sure at all.
I begin with 1941 , when I left the University of Missouri to
join the Federal Reserve Bank of Philadelphia. That decision
was determined by several converging forces. First, Alfred H.
Williams, President, and Thomas B. McCabe, Chairman, asked
me to join the staff of the Bank. Second, I found it increasingly
difficult to inspire students who faced imminent induction into
the armed forces to get excited about matters of money and
finance. Third, this lull in student interest seemed an appropri­
ate occasion to learn about central banking from the inside, so
that I could be a more effective teacher when they came back.
Fourth, I was a self-assured young man who had definite views
as to what monetary policy was proper and felt I could help im­
prove the performance of the Federal Reserve System. Frankly,
as observer, I wondered how the Reserve System could make
so many mistakes. Incidentally, it probably comes as no sur­
prise to you to learn that I now often wonder how observers
can be so sure that correct policy is really as simple and obvious
as they say it is.
Some problems that did not occur to me as student or even
as teacher now trouble me more and more as I acquire experi­
ence and feel the responsibilities of a practitioner. The first
concerns the inadequacy of contemporary monetary theory to
serve —as it should —as a basic tool for practitioners.
1 should state at the outset that I have a firm conviction —or
prejudice, if you prefer—that those who purport to contrast
theory with practice are rearing a false dichotomy. To me the

real issue is not theory versus practice, but operationally valid
theory and relevant practice, on the one side, versus false theory
—or no theory, or pure empiricism, or solipsism —and bad prac­
tice on the other. My own view always has been that actions
should be based upon an internally consistent theoretical struc­
ture whose premises are relevant to the actual world in which
we live.
Since I have always held this view, you might appropriately
ask what has happened to me since I left the University of
Missouri some two decades ago? An answer that might appeal
to you is simply to confess that I contracted what some of
my academic friends call the occupational disease of central
bankers: an insistence on the impotence of monetary policy
when economic developments go awry and a not-too-reluctant
willingness to accept some credit when developments are fa­
vorable. You can understand why this answer does not satisfy
me completely.
What seems to me to have happened is that a sanguine hope,
indeed expectation, of those days has not materialized. This
was the optimistic belief that as more qualified individuals de­
voted greater effort to developing monetary theory a generally
accepted core of ideas would emerge. I reached this conclusion
from countless hours of discussion of the history of science,
especially with DR Scott and August Maffry. Incidentally, I
had a hunch that the version of truth toward which all were
heading was almost exactly what I had been taught and was
teaching. Even in those days I was willing to make a few minor
concessions to those benighted scholars who had not had my
particular —almost unique! —advantages.
Once I became an insider, living with problems from day to
day, I learned that my theory did not pass the test of experience.
Ever since, my problem has been to ascertain or determine
what theory is valid and operational. Many friends and other
scholars have done their best to help me. They have told me
how to behave. My tragedy is not lack of answers but rather




8

ESSAYS IN MONETARY POLICY

lack of agreement among the answers. This is quite under­
standable, because each of us is a product of his own heredity
and environment, and these differ. I speak of my contem­
poraries to illustrate the point. Why is it that so many of
Kemmerer's students at Princeton became pure gold standard
disciples? Why did so many of Willis* students at Columbia
come to accept the real bills doctrine of commercial banking?
Turning to myself, why did the arguments of these eminent
teachers, which were so cogent with their students, leave me
unconvinced, even though we discussed them thoroughly —or
at least so it seemed to me —in graduate seminars? Could it
have been merely coincidence that my initial teachers in this
field were Harry Gunnison Brown and J. Harvey Rogers, both
of whom just happened to have come to Missouri after being
favorite students of Irving Fisher at Yale? Is it mere happen­
stance that I still feel a twinge of conscience when I cannot
accept the mechanistic approaches of Friedman and War bur­
ton? I must confess, however, that a little more exposure to
Meltzer and Brunner may finally liberate me.
It is Elmer Wood who convinced me of the inadequacy of
this approach. Indeed, my intellectual debt to him is unlimited.
A decade ago I acknowledged the debt with a token payment
by dedicating to him the results of several years of intensive
technical work, published under the title: Die Tatigkeit der
Reichsbank von 1876 bis 1914 . Anyone who doubts that a pro­
fessor influences his students might compare the basic train of
thought in this essay with that in Wood’s monumental English
Theories of Central Banking Control: 1819 - 1858. If he still has
doubts, he might try to uncover this train of thought anywhere
else at an earlier date.
Incidentally, I should like to take this occasion to commend
the University of Missouri Press for publishing his Monetary
Control. I have a hunch that some readers and reviewers as­
sumed that they could skip, without loss, the dozen pages
appended under the characteristically innocuous title: “Note




Confessions of a Central Banker

on Bank Deposits —How They Originate and What Deter­
mines Their Amount.” My own view is that there is revolution­
ary yeast in those pages, which, if absorbed, could energize
monetary theory for many years to come.
Meanwhile, quotations from governmentally-sponsored proj­
ects will illustrate how far apart contemporary observers are
—not as to the institutions, the magnitudes, and other "facts”
of the financial world, but on the interpretation of these facts
and on the essential nature of the task that confronts central
bankers. As a responsible practitioner, I introduce these quota­
tions with these gratuitous comments to the authors: When I
become depressed, I envy your certainty; when I juxtapose your
profundities, I wonder how each of you can be so sure —and
yet be unable to persuade the other!
The first series of quotations is from the Report of the socalled Radcliffe Committee on the Working of the Monetary
System. The first substantive comment in that Report reads as
follows:
. . it is the liquidity of the economy, rather than
the ‘supply of money5 that the authorities should seek to affect
by their use of monetary measures . . .” (par. 10 ). The Com­
mittee repeats this view later in these words:
. . the object
of the monetary authorities must be to act, not upon the ‘supply
of money’ ( however that is defined) but on the liquidity posi­
tion of the system as a whole.” (par. 125 ). Although I have read
the Report several times and key paragraphs many times, I
have not come across a precise, operational definition of liquid­
ity. The Committee does rephrase this basic idea, however, in
these words: “The authorities thus have to regard the structure
of interest rates rather than the supply of money as the centre­
piece of the monetary mechanism. This does not mean that the
supply of money is unimportant, but that its control is incidental
to interest rate policy.” (par. 397).
The second series of quotations is taken from the work Pro­
fessor Meltzer is doing for the House Committee on Banking
and Currency: “. . . the relation of the money supply to eco­




ESSAYS IN MONETARY POLICY

lO

nomic activity is sufficiently close that we can count on a rea­
sonably reliable and predictable effect, provided that we have
adequate control of the supply of money.” He then goes on to
say: “Monetary policy is predicated on the notion that there is
a reliable connection between the quantity of money and
money income. . . . Evidence from a large number of coun­
tries and many different time periods suggests that money and
money national income are closely associated.”
Incidentally, it is when I read such dogmatism as that of
Meltzer and Brunner that I repair to Goethe’s Faust and recall
Mephistopheles’ sage comment:
Grau, teurer Freund, ist alle Theorie,
Und grun des Lebens goldner Baum .3
In the hearings now being conducted by the House Committee
on Banking and Currency, a former president of the American
Economic Association and winner of the John Bates Clark
Medal of that association, warns the Committee against the
advice that he expected another Clark Medal winner to give
them. Incidentally, he anticipated the evidence correctly. Of
course, it is frequently easier to predict what an economist will
say than how an economy will function.
I do not venture to guess what monetary policy would be
like if the Board of Governors or the Federal Open Market
Committee consisted exclusively of such individuals. One might
be able to predict what each would say and that the debate
would be interesting; but how does any group reach even a bare
majority decision except through compromise and concession
on the part of individual members? And if each is so sure he is
right, how can he make any concession? Yet, obviously, the
final result must be one policy for the group, not a different
policy for each member. An alternative is to have a single head
of the central bank. This might satisfy —at least initially —the
3 Goethe, Faust, 11 2038.9 :

Grey, dear friend, is all theory,
And green is life's golden tree.

11

person selected; but it is understandably not a solution we have
been willing to accept.
I hope that the quotations from those who are so free with
advice will give you some feeling for what mere practicing cen­
tral bankers are up against. We are presumed to have the power
and are expected to do what is “right” with liquidity, with the
structure and level of interest rates, with the supply of money,
with —well, you name it, since someone is almost certain to
have advised us to devote exclusive attention to it or to ignore it.
The second problem is, What may reasonably be expected of
the practitioner in view of the current status of theory? You
appreciate, of course, that the answer of a responsible practi­
tioner may differ a bit from that of the observer. Some twenty
years ago, as observer, I criticized Sir John Clapham for his
defense of the management of the Bank of England during an
interval in the nineteenth century. Sir John had written: “Fair­
ness to the much criticized Court of the late thirties and early
forties makes it necessary to say that most of the advice that it
got, or might have got, from economists, statesmen, or the out­
side business world was likely to be crude, contradictory, or
as tentative as its own policies.” I said: “It obviously is unrea­
sonable to judge policies of, say, 1839, by standards that would
be applied to current policies; but is it unreasonable to judge
them with reference to the best thought that had been devel­
oped by 1839?” My answer was implied so clearly that I did
not put it down. But there was a gaping flaw in my reasoning.
How is the mere practitioner to determine which, among the
wide variety, is the best thought of his contemporaries ? It may
be that the change in my answer from No to Yes as to what is
unreasonable is but another illustration of the “strange juices
that the wine-press of responsibility squeezes from our veins.”
I must confess that as I have lived with this problem, study­
ing as much of the literature as time allows, I am tempted, on
those occasions when the mind goes stale, to say, “A plague on
all your theories.” But those are only momentary lapses. Deep




ESSAYS IN MONETARY POLICY

down, I know that I do not mean it. I mention such frustration
only to remind you that practitioners are not above occasional
yearning for nirvana, where accumulated wisdom is adequate
to assure perfection. It is only some observers, however, who
already claim nirvana citizenship.
What really disturbs me is the frequent pretense to knowl­
edge and comprehension far beyond what is justified at the
present time. The simple truth is that no one comprehends
enough to be an expert in central banking. We have no con­
trolled experiments. The observer who deals with virtual move­
ments, as though he knew exactly what would have happened
if something else had been done, is simply naive.
This is not a counsel of despair but of patience. Central bank­
ing is an infant, as human institutions go. We know precious
little, have almost everything to learn. As Professor Culbertson
wrote last month, "Monetary theory . . . is in a terribly un­
satisfactory condition.” But our hope is to learn more as rapidly
as we can. My task, as practitioner, is to learn and modify as
we go along —inspired by the builders of the great cathedrals
who constructed magnificent edifices that differed from the
presumed blueprints of the original architects. What makes the
whole business fascinating —to say nothing of tolerable —is a
feeling of participation in an important dynamic process rather
than dedication to a foregone or final result.
These are among the experiences that have convinced me
that a practitioner must maintain an open mind. By this I do not
mean a mind that is forever convinced by the latest argument
it has heard. Such a mind is not open but empty. An open mind,
rather, is one with convictions whose strength arises from the
intellectual compulsion of the arguments on which they are
based and on the amount and depth of experience with which
they have been tested. Some opinions should be held only
lightly; others should be held with firm conviction. An open
mind recognizes human fallibility and has a genuine impulse
and willingness to expose all its opinions to new evidence and




Confessions of a Central Banker

13

new arguments and a correlative determination to change al­
ways and only as new evidence dictates.
Recognition of one’s own fallibility implies a tolerance for
the ideas of others. It is a mark of immaturity to harbor "the
old conceit of being wiser than posterity —wiser than those who
will have had more experience,” as Jeremy Bentham phrased
it. This attitude has particular application for a mortal central
banker who heads an institution that is chartered in perpetuity.
Obviously, he is and must be responsible for everything that
his institution does. But he should not pretend to be the sole
source of all truth. Instead, his institution can discharge its
obligations fully only if he develops and maintains a profes­
sionally competent, responsible, enthusiastic staff with integrity
and freedom of mind.
I move now to a problem of communication. How does one
inform the public with respect to policy, and how does he issue
directives to those who execute policy? Let me state at the
outset that there is no disagreement in principle between ob­
servers and practitioners as to the desirability of a maximum of
lucidity in communications. There is, however, a significant
difference of opinion as to how much precision is possible.
I have struggled with this problem both as observer and as
practitioner. As observer I desired precise and detailed com­
munications so that I could evaluate accurately, in my own
view, both policy and execution. I must confess that I was
impatient that verbal information was not expressed in terms
that could be programmed into our contemporary mental com­
puters. As practitioner I find that precise programming must
ignore the unexpected and that it is the unexpected that occurs
almost constantly in details and occasionally in matters of major
import.
Perhaps I can illustrate what I have in mind from an entirely
different field. I remember discussing the problem with Robert
V. Roosa, currently Under Secretary of Treasury for Monetary
Affairs, when he was managing the Trading Desk at the Federal




14

ESSAYS IN MONETARY POLICY

Reserve Bank of New York. He told me of an experience when
he was on the staff of General Omar Bradley during the Second
World War. After a particular briefing session, toward the end
of the Battle of the Bulge at the beginning of March, 1945,
Bradley issued a General Order to the Third Army that read
substantially as follows: “Conduct an aggressive defense, main­
taining contact with the enemy.” Over the first 48 hours that his
General Order was in effect, the Third Army advanced 48 miles.
I am sure you will agree that was quite a defense! Obviously,
the results were not those that would have occurred had the
General Order been more specific, had it read, say, “Retreat
to a specified position,” or “Hold on a specified line.” Yet every­
one agreed that the field commanders had carried out the intent
of the Order; and, indeed, the advance was a notable achieve­
ment.
It would seem possible that the General Order was based on
inadequate intelligence. It resulted in advance rather than in
retreat, however, because the field commanders comprehended
the general strategy, of which the General Order was a part.
What became clear, as the fighting developed, was the im­
portance of the adjective “aggressive” and of the clause “main­
taining contact with the enemy,” relative to the noun “defense.”
The enemy happened to be retreating, rather than advancing,
as some of the intelligence had seemed to indicate.
Please do not misunderstand me. I heartily endorse the view
that we should strive for as much precision as possible. But I
think it would be a serious and, possibly, eventually a fatal
mistake to assume that we know and understand more about
the functioning of our economic system than we in fact know
and understand. We should not give precise directions based
on assumptions that may not correspond with reality as it de­
velops.
In the field of Federal Reserve policy it is possible, of course,
to give very precise directives to the Manager of the open mar­
ket account. It must be recognized that such directives would




Confessions of a Central Banker

15

have to be couched in terms that the Manager can in fact exe­
cute. They would have to be written in terms of the amount
and issues of Government securities to be bought or sold, re­
gardless of what happens to yields, or in terms of yields, with­
out regard to what happens to the portfolio. They cannot be
written precisely in terms of both —at the present state of our
knowledge. It is an elementary error to suppose that they can
be written precisely in terms of the supply of money, however
defined, or in terms of some reserve total, be it total reserves,
excess reserves, free reserves, borrowed reserves, or whatever,
or in terms of the liquidity of the economy —whatever that may
mean. The reason is that each of these magnitudes is influenced
by factors over which the Manager has no immediate or direct
control, and the present state of our knowledge is insufficient
to predict the behavior of these other factors with sufficient
accuracy to make appropriate allowances for changes in them.
I confess that I have on occasion couched a directive —or
voted for a directive couched —in inappropriate terms. But
this always has been with the knowledge that the Manager was
present to hear all the discussion that led to the formulation of
the directive. I participate in rotation in the development of the
day-to-day program of action designed to carry out the direc­
tive of the Federal Open Market Committee. I recall occasions
when, though the intent of the Committee was clear to any
veteran who had attended the meeting, the directive had not
been phrased with skill. Under these circumstances, the daily
program is designed to carry out the intent of the Committee,
not the precise wording of the directive. In this connection it
should be remembered that each member of the Committee
receives a daily report of intended action and that a special
meeting could be arranged at once if there were questions as
to misinterpretation.
As one who has spent many man-years trying to understand
the functioning of central banks, in the belief that it is the only
way in which we can learn from history so as to improve our




l6

ESSAYS IN MONETARY POLICY

performance, I admit that interpretation would be easier and
more useful if every directive were straightforward and pre­
cise. I agree that maximum effort should be devoted to achiev­
ing this result. At the same time I would emphasize the inherent
difficulties in our present state of knowledge and also that the
practitioner is necessarily a man of action, more interested in
getting on with the job than in creating a record that is easy
to follow.
The problems of relating principles to directives to opera­
tions is not unique to central banking. General von Clausewitz
had this to say about it in his Principles of W ar : “The conduct
of war resembles the workings of an intricate machine with
tremendous friction, so that combinations which are easily
planned on paper can be executed only with great effort.”
Speaking from experience, I am tempted to paraphrase another
Clausewitz dictum: “The results on which we count are never
as precise as is imagined by someone who has not carefully ob­
served a money market and become used to it.”
If, now, you force me to squeeze my confession into that ball
that T. S. Eliot talked about, I would answer by violating my
commitment to Professor Walker and quoting Robert Frost:

The Road Not Taken
Two roads diverged in a yellow wood,
And sorry I could not travel both
And be one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;
Then took the other, as just as fair,
And having perhaps the better claim,
Because it was grassy and wanted wear;
Though as for that the passing there
Had worn them really about the same,
And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!




Confessions of a Central Banker

17

Yet knowing how way leads on to way,
I doubted if I should ever come back.
I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I —
I took the one less traveled by,
And that has made all the difference.4
To this I would add only what Mephistopheles told Faust:
Du bleibst doch immer was du bist.5
If you trust my memory, I will conclude this confession with
a thought that Myron Watkins expressed in concluding a
course in Labor Problems just forty years ago: “Visionaries and
cynics alike are unsafe guides on society’s great adventure/’
The world in which we live never quite measures up to the
world of which we dream. This does not mean either that we
should cease to live or that we should give up our dreams, but,
rather, that we should strive constantly both to enrich our
vision and to improve our performance.
