Preface to 2007 WordPress.com Republication
This book germinated when I was 18 or 19 years of age in Paris, Helsinki and London, and it was first published when I was 34 in Honolulu. I came to economics from natural science (biology, chemistry, physics), not mathematics. It was inevitable I would be drawn to the beauty of philosophy as a theoretical discipline while being driven, as a post-Independence Indian, to economics as the practical discipline that might unlock secrets to India’s prosperity and progress. I belonged to an ancient family of political men, and my father, who had joined India’s new foreign service the year before I was born, inculcated in me as a boy an idea that I had “a mission” (though he later forgot he had done so).
I was fortunate to fail to enter Oxford’s PPE and instead go to the London School of Economics. LSE was at an intellectual peak in the early 1970s. DHN Johnson in international law, ACL Day in international monetary economics, Brian Griffiths vs Marcus Miller in monetary economics with everyone still in awe of Harry Johnson’s graduate lectures in macroeconomics, Ken Wallis, Graham Mizon, JJ Thomas, David Hendry in econometrics with the odd lecture by Durbin himself – I was exposed to a fully grown up intellectual seriousness from the day I arrived as an 18 year old. Michio Morishima as my professorial tutor told me frankly that, as an Indian, I would face less prejudice in Western academia than in the private sector, and said he was speaking from experience as a fellow-Asian. He turned out to be wrong but it was wise advice nevertheless, just as wise as his requiring pupils to read Hicks’ Value and Capital (which, in our undergraduate mythology, he himself had read inside a Japanese gunboat during war).
What was relatively weak at LSE was general economic theory. We were good at deriving the Best Linear Unbiased Estimator but left unsatisfied with our grasp of the theory of value that constituted the roots of our discipline. I managed a First and was admitted to Cambridge as a Research Student in 1976, where fortune had Frank Hahn choose me as a student. That at the outset was protection from the communist cabal that ran “development economics” with whom almost all the Indians ended up. I was wholly impecunious in my first year as a Research Student, and had to, for example, proof-read Arrow and Hahn’s General Competitive Analysis for its second edition to receive 50 pounds sterling from Hahn which kept me going for a short time. My exposure to Hahn’s subtle, refined and depthless thought as an economist of the first rank led to fascination and wonderment, and I read and re-read his “On the notion of equilibrium in economics”, “On the foundations of monetary theory”, “Keynesian economics and general equilibrium theory” and other clear-headed attempts to integrate the theory of value with the theory of money — a project Wicksell and Marshall had (perhaps wisely) not attempted and Keynes, Hicks and Patinkin had failed at.
Hahn insisted a central question was to ask how money, which is intrinsically worthless, can have any value, why anyone should want to hold it. The practical relevance of this question is manifest. India today in 2007 has an inconvertible currency, vast and growing public debt financed by money-creation, and more than two dozen fiscally irresponsible State governments without money-creating powers. While pondering, over the last decade, whether India’s governance could be made more responsible if States were given money-creating powers, I have constantly had Hahn’s seemingly abstruse question from decades ago in mind, as to why anyone will want to hold State currencies in India, as to whether the equilibrium price of those monies would be positive. (Lerner in fact gave an answer in 1945 when he suggested that any money would have value if its issuer agreed to collect liabilities in it — as a State collects taxes – and that may be the simplest road that bridges the real/monetary divide.)
Though we were never personal friends and I did not ingratiate myself with Hahn as did many others, my respect for him only grew when I saw how he had protected my inchoate classical liberal arguments for India from the most vicious attacks that they were open to from the communists. My doctoral thesis, initially titled “A monetary theory for India”, had to be altered due to paucity of monetary data at the time, as well as the fact India’s problems of political economy and allocation of real resources were more pressing, and so the thesis became “On liberty and economic growth: preface to a philosophy for India”. When no internal examiner could be found, the University of Cambridge, at Hahn’s insistence, showed its greatness by appointing two externals: C. J. Bliss at Oxford and T. W. Hutchison at Birmingham, former students of Hahn and Joan Robinson respectively. My thesis received the most rigorous and fairest imaginable evaluation from them.
I had been attracted to Cambridge partly by its old reputation for philosophy, especially that of Wittgenstein. But I met no worthwhile philosophers there until a few months before I was to leave for the United States in 1980, when I chanced upon the work of Renford Bambrough. Hahn had challenged me with the question, “how are you so sure your value judgements promoting liberty blah-blah are better than those of Chenery and the development economists?” It was a question that led inevitably to ethics and its epistemology — when I chanced upon Bambrough’s work, and that of his philosophical master, John Wisdom, the immense expanse of metaphysics (or ontology) opened up as well. “Then felt I like some watcher of the skies, When a new planet swims into his ken; Or like stout Cortez when with eagle eyes, He star’d at the Pacific…”
It has taken me more than a quarter century to traverse some of that expanse; when I returned to Britain in 2004 as the Wincott Visiting Professor of Economics at the University of Buckingham, I was very kindly allowed to deliver a public lecture, “Science, Religion, Art and the Necessity of Freedom”, wherein I repaid a few of my debts to the forgotten work of Bambrough and Wisdom — whom I extravagantly compared with the Bodhisattvas of Mahayana Buddhism, also saying that the trio of Wittgenstein, Wisdom and Bambrough were reminiscent of what Socrates, Plato and Aristotle might have been like.
I had written to Bambrough from within Cambridge expressing my delight at finding his works and saying these were immensely important to economics; he had invited me to his weekly discussion groups at St John’s College but I could not attend. Between 1979 and 1989 we corresponded while I worked in America on my application of his and Wisdom’s work to problems in economics. We met only once when I returned to Cambridge from Blacksburg for my doctoral viva voce examination in January 1982. Six years later in 1988 he said of my Philosophy of Economics, “The work is altogether well-written and admirably clear”, and on another occasion he said he was “extremely pleased” at the interest I had taken in his work. The original preface of Philosophy of Economics said he was not responsible for the use I had made of his writings, which I reiterated in the 2004 lecture. At our meeting, he offered to introduce me to Wisdom who had returned to Cambridge from Oregon but I was too scared and declined, something I have always regretted since. It is only in the last few years that I have begun to grasp the immensity of Wisdom’s achievement in comprehending, explaining and extending the work of both Wittgenstein and Freud. His famous “Virginia Lectures” of 1957 were finally published by his admirers with his consent as Proof and Explanation just before his death in 1993. As for Bambrough, I believe he may have been or become the single greatest philosopher since Aristotle; he told me in correspondence there was an unfinished manuscript Principia Metaphysica (the prospectus of which appeared in Philosophy 1964), which unfortunately his family and successors knew nothing about; the fact he died almost in obscurity and was soon forgotten by his University speaks more about the contemporary state of academic philosophy than about him. (Similarly, the fact Hahn, Morishima and like others did not receive the so-called Economics “Nobel” says more about the award than it does about them.)
All I needed in 1980 was time and freedom to develop the contents of this book, and that I found in America — which I could not have done in either Britain or India. It would take eight or nine very strenuous years before the book could be written and published, mostly spent at Virginia Polytechnic Institute (1980-1985) and the University of Hawaii (1986-1990) Economics Departments, with short interludes at Cornell (Fall 1983) and Brigham Young (1985-86). I went to Virginia because James M. Buchanan was there, and he, along with FA Hayek, were whom Hahn decided to write on my behalf. Hayek said he was too old to accept me but wrote me kind and generous letters praising and hence encouraging my inchoate liberal thoughts and arguments. Buchanan was welcoming and I learnt much from him and his colleagues about the realities of public finance and democratic politics, which I quickly applied in my work on India, published in 1984 in London as Pricing, Planning & Politics: A Study of Economic Distortions in India and republished elsewhere here. The visit to the Cornell Economics Department was really so I could talk to Max Black the philosopher, who represented a different line of Wittgenstein’s students, and Max and I became friends until his death in 1988.
Buchanan’s departure from Blacksburg led to a gang of inert “game theorists” to arrive, and I was immediately under attack – one senior man telling me I was free to criticise the “social choice” work of Amartya Sen (since he was Indian too) but I was definitely unfree to do the same of Sen’s mentor, Kenneth Arrow, who was Jewish! (Arrow was infinitely more gracious when he himself responded to my criticism.) On top of that arose a matter of a woman, fresh off the aeroplane from India, being assaulted by a senior professor, and when I stood for her against her assailant, my time in Blacksburg was definitely up.
The manuscript of this book was at the time under contract with University of Chicago Press, and, thanks to Mrs Harry Johnson there, I had come in contact with that great American, Theodore W. Schultz. Schultz, at age 81, told me better to my face what the book was about than I had realised myself, namely, it was about economics as knowledge — its subject-matter was the epistemology of economics. Schultz wrote letters all over America on my behalf (as did Milton Friedman at Stanford and Sidney Alexander of MIT, whom I had also met and become friends with), and I was able to first spend a happy year among the Mormons at Brigham Young, and then end up at the University of Hawaii where I was given responsibility for the main graduate course in macroeconomics. I taught Harry Johnson-level IS-LM theory and Friedman-Tobin macroeconomics and then the new “rational expectations” vs Keynesian material.
I was also offered a large University grant to work on “South Asia”, which led to the books Foundations of India’s Political Economy: Towards an Agenda for the 1990s, and Foundations of Pakistan’s Political Economy: Towards an Agenda for the 1990s, both created by myself and WE James, and which led to the origins of India’s 1991 economic reform and the India-Pakistan peace process as told elsewhere. Also, this book came to be accepted for publication by Routledge, as the first economics book in its famed International Library of Philosophy.
Just as I was set to be evaluated for promotion and tenure at the University of Hawaii, I became the victim of a most vicious racist defamation (and there was some connection with Blacksburg). Quite fed up with the sordidness of American academia as I had experienced it, I sued in the federal court, which consumed much of the next half dozen years as the case worked its way through the United States Supreme Court twice. Milton Friedman and Theodore W. Schultz stood as expert witnesses on my behalf but you would not have known it from the judge’s ruling. There had been not only demonstrable perjury and suborning of perjury by the State of Hawaii’s officers, there was also “after-discovered” evidence of bribery of court-officers in the US District Court for the District of Hawaii, and I had to return to India in 1996 quite exhausted to recuperate from the experience. “Solicitation of counsel, clerks or judges” is “embracery curialis”, recognized as extrinsic fraud and subversion of justice since Jepps 72 E R 924 (1611), “firmly established in English practice long before the foundation” of the USA, Hazel Atlas, 322 US 238 (1943). “Embracery is an offense striking at the very foundation of civil society” says Corpus Juris 20, 496. A court of equity has inherent power to investigate if a judgement has been obtained by fraud, and that is a power to unearth it effectively, since no fraud is more odious than one to subvert justice. Cases include when “by reason of something done by the successful party… there was in fact no adversary trial or decision of the issue in the case. Where the unsuccessful party has been prevented from exhibiting fully his case, by fraud or deception practised on him by his opponent, as…where an attorney fraudulently or without authority assumes to represent a party and connives at his defeat; or where the attorney regularly employed corruptly sells out his client’s interest to the other side ~ these, and similar cases which show that there has never been a real contest in the trial or hearing of the case, are reasons for which a new suit may be sustained to set aside and annul the former judgment or decree, and open the case for a new and a fair hearing….” (Hazel Atlas). There is no time-limit in United States federal law for rectification of fraud on the court of this sort, and I remain fully hopeful today of the working of American justice in the case.
The practical result was that this book was never able to be properly publicized among economists as it would have been had I become Professor of Economics at the University of Hawaii by 1992 as expected. The hardback sold out quickly on its own steam and went into paperback by 1991, and a friend told me it was being used for a course at Yale Law School. The reviews were mostly intelligent. Upon returning to Britain as the Wincott Visiting Professor in 2004, I found times had changed and so had Routledge who would not keep it in print let alone permit a second revised edition. But I am now free to republish the book as I please, and today in 2007, with the Internet growing to a maturity which allows the young geeks at WordPress.com to want to encourage blogging worldwide, I can think of no more apt place to reproduce the first edition of this book than here at my own blog www.independentindian.com.
This is not a second or revised edition, and it is unchanged in content except for this lengthy new preface made necessary by the adventures and dramas the book’s author found himself unwittingly part of since its first publication. I am 52 now and happy to say I endorse the book just as I had published it at 34, though I do find it a little impatient and too terse in a few places. The 1991 paperback corrected a few slight errors in the 1989 hardback, and has been used. I am planning an entirely new book which shall have its roots in this one though it will be mostly in philosophy and not economics — the outlines it may take may be seen in the 2004 public lecture I gave on the work of Bambrough and Wisdom mentioned above and published elsewhere; its main aim will be to uncover for new generations the immense worth there is in their work which is in danger of being lost.
At least two names failed to appear in the original list of acknowledgements. G. Bruce Chapman, now of the University of Toronto, and I talked much of serious ethics and political philosophy when I first arrived at Cambridge in 1976. And in 1980 in Blacksburg, Anil Lal, then a graduate student and house-painter, borrowed my copy of Bambrough’s work, read it, and later made a comment on the metaphysics of John Wisdom which allowed me to see things more clearly.

Preface to First Edition
The publication of this work marks the end of an adventure of more than a decade and a half, most of the writing being done between 17 December 1980 and 22 May 1987. It has been quite perilous at times, especially as a foreigner in the West, and over the years many teachers, colleagues, friends and members of family have contributed to the author’s learning with their thoughts and actions. A number of senior scholars in economics and philosophy — especially Professor Frank Hahn, Professor James Buchanan, Professor Sidney Alexander, Professor Milton Friedman, Professor Max Black, Professor Sidney Alexander, Professor Amartya Sen, Professor Peter Bauer, Professor T. W. Hutchison and Dr C. J. Bliss, have lent their support to the work as it developed, even when they may have not known of its final form, or disagreed with its content, or been themselves a subject of its criticism. Most especially, the work has been honoured in the last six years with the unwavering encouragement of Professor T. W. Schultz of the University of Chicago. And Professor Ted Honderich of University College London has shown it the kindest consideration, without which publication would have been much delayed. Finally, a large philosophical debt will be seen to be owed to the work of Mr. Renford Bambrough of St. John’s College, Cambridge; however he should not be considered responsible for the use that has been made here of his writings.
