Apropos *Philosophy of Economics*
“Dr. Roy’s book, Philosophy of Economics, which I have read in galleys, I regard as a masterpiece, not only in economic analysis but in philosophic analysis as well.” Sidney Hook 1989
“I shall have to ponder your rejection of the Humean position which has, I suppose, been central in not only my thought but that of most economists. Candidly, I have never understood what late Wittgenstein was saying, but I have not worked very hard at his work, and perhaps your book will give guidance.” Kenneth J. Arrow, letter to the author, 1989
“I was grateful for the reminder of the passage of Aristotle at which I had not looked for many years and found the criticism of Arrow well justified and important.” FA Hayek, letter to the author, 1981
“It is an extraordinarily well-written and well-thought through book that shows a wide-ranging capacity and understanding of economics as a discipline in both its macro and micro aspects.” Milton Friedman 1991, Evidence in the US District Court for the District of Hawaii.
“There is no doubt whatsoever that he has a thorough and deep understanding of the major issues that have occupied macroeconomics over the past fifty years…. It is a sign of real understanding that Roy can state these ideas not in terms of jargon, not in terms of equations or technical terms, but in straightforward English using only a minimum of specifically economic terminology. All in all, it is a very knowledgeable and sophisticated performance.” Milton Friedman, 1989
“I had the privilege of reading early drafts of this book. I saw it emerge as an in-depth analysis of the philosophical foundations of economics. It is scholarship of a high order. It is an original contribution of major importance to economic thought.” Theodore W. Schultz 1989
“The core of Roy’s study is devoted to the nature and grounds of economics as knowledge; it examines the basic intellectual roots of economics. It is cogent and, what is exceedingly rare these days, it is refreshingly lucid…. Roy’s book is in several important respects an original contribution, the most important being his treatment of the philosophical foundations of economics as knowledge. He is all too modest in assessing the importance of his contribution.” Theodore W. Schultz, 1983
“(This) is a very ambitious work directed at the foundations of normative judgements in economics. The author arrives at some conclusions very closely matching those I arrived at some years ago. It is clear, however, that Dr. Roy arrived at his conclusions completely independently. That is all the more piquant to me in that the philosophical underpinning of his work is the development of philosophy in England from the later Wittgenstein, while mine derives principally from earlier work in the United States by the pragmatists… Dr. Roy reveals a clear understanding of the methodological positivism that invaded economic policy analysis in the thirties and still dominates the literature of economics…. Following Renford Bambrough….he arrives at a position equivalent to that of the American pragmatists, especially Dewey, who insist that the problematic situation provides the starting point for the analysis of a problem even though there are no ultimate starting points. The methodological implication is the support of inquiry as fundamental, avoiding both scepticism and dogmatism. Roy develops his position with a great deal of attention to the ramifications of the problem both in philosophy and in economics. While his treatment of economic questions is ‘from the top down’ so to speak, it reveals a strong command of conventional economic analysis. He writes very well and thinks very clearly. He is certainly not afraid to tackle the big questions. His book reveals a keen mind, ready to pay almost undue respect to his forerunners, but anxious also to achieve originality….” Sidney Stuart Alexander, 1985
“I know that I have to continue to bear the responsibility for things that I wrote nearly fifty years ago. I am however glad that your attention has been drawn to that passage written much more recently….building up to what I think is a coherent point of view very different from that which I took in ’34 and ’39…. concerned with a field not far removed from that you reach…” John R Hicks, letter to the author, 1984
“A work altogether well written and admirably clear.” Renford Bambrough, 1985
“I like very much the courage in trying to produce a genuine philosophy of economics. Such a book is badly needed and could be very useful to economists. The fine use made of extensive readings in older as well as contemporary theorists and the splendid choice of quotations would themselves be worth the price of admission. The style maintains a fine level of clarity and emphasis.”Max Black 1985
“The discussion of Arrow’s theorem under unintended interpretations focuses our understanding on what is really fundamental to this famous result…. Roy has obviously thought much harder about the foundational and methodological problems in economics than most of his fellow-economists.” Anonymous
“Roy’s platonist view of what is the purpose of government is very odd at this stage of history. He seems to suppose that there is an objectively best state of affairs which we must simply discover. The more urgent issue in politics is generally not that of knowing what is the best thing to do but of dealing with conflicting interests. Conflict of interests is not merely disagreement over facts.”Anonymous
“The author has performed a very valuable service for economists interested in the philosophical problems and positions discussed. He has not misrepresented the positions he discusses and his account of various issues and different positions on those issues is philosophically adequate. Many economists will be stimulated as a result of reading this work to reconsider their own positions on the issues Roy addresses.” Anonymous
“The work has many strengths. It is wide in its references and its outlook. Its endorsement of objectivism is both right and timely. The chapter on mathematics in economics is particularly fine.” Anonymous
“The author intends to discuss some of the central philosophical questions facing modern economic theory. In the foreground is a disposition of the conventional problem of value-independence. Roy sees the value-independence postulate as “Hume’s Scepticism”. He defines Hume’s First and Second Laws on the basis of two signified propositions taken from R. M. Hare. (1) From positive empirical premises, no normative postulate can be derived; in order to establish obligatory propositions, at least one normative proposition is needed. (2) In a specified economic context, after all empirical and formal/logical matters are resolved, little scope exists for further intersubjectively valid answers. Valuations beyond this limit are based on the subjective feelings of the economist to the concerned problem. The scientific/theoretical attitude representative of most economists of the 20th century has been based on this characteristic Humean scepticism. To show this, the author reviews short representative quotations from some of the known names of recent economic theory: Friedman, Myrdal, Lionel Robbins, P. A. Samuelson, Hicks, Joan Robinson, Hayek, Oskar Lange, Schumpeter, Arrow, Blaug, Frank Hahn. Subsequently, the author raises the point as to what explains this scientific-theoretical approval. A cursory survey of important real and virtual historical developments since antiquity confirms that the essential reason for the reported wide acceptance of a humean position by the economic scientist indeed could have been as a defensive posture against dogmatism and political dictatorship (“It is part of the democratic reaction against medieval authoritarianism” p.45). Conditioned by their “disgust with the tyrannies and ideologies of the twentieth century”, these authorities tried to protect economic science and guarantee the objectivity of research by resort to moral scepticism. Hence the author arrives at the starting position of his actual subject: After using Hume to escape from dependence on Plato e tutti quanti, has not value-free economics gotten into a fresh dependence, namely, moral scepticism and its philosophical consequence, moral indifference? Here too a contradiction is shown to arise, namely, that each argumentation against the normative can stand its ground only through normative premises. Thus ultimately something like correct standards become necessary. This however is only a marginal problem compared to a very much more important point: whether the moral scepticism permeating the strict scientific-theoretical position, is not just part of a very much more comprehensive scepticism, which includes Hume’s own criticism of induction as well. But then the same scepticism makes positive theory dubious as well: “Either all of positive economics is attacked with just as much scepticism as anything in normative economics, or we accept one and reject the other when instead there are reasons to think they share the same ultimate grounds and must be accepted or rejected together”(p.47). The author illustrates the difficulties with radical scepticism in a continental traversal of economic theory: micro and macroeconomics, mathematical economic theory and welfare theory are stations on this tour. A solution of the problem in the strict sense is not given nor could have been expected. But Roy delivers a methodical rule which permits a more exact definition of the limits to which normative discussion can take place precisely and objectively: first, to distinguish always whether an objective answer is at all possible to certain questions, and secondly, to ask who is competent or in the best position to give an answer. For readers interested in a new, thoroughly subtle discussion of a basic yet customary problem, this book will be profitable reading. However, the author could have argued some matters slightly more elaborately and others less redundantly, and set forth the central idea more clearly through appropriate summaries.”Karl Georg Zinn in Jahrbücher für Nationalökonomie und Statistik / Zeitschrift für Wirtschaft und Statistik. Vol. 209, Nr. 5/6 (May 1992), p 573-574 (translated from the German by N Bhattacharya).

“Not the book to set off the revolution in economic epistemology and it is not even a reliable introduction to the field for undergraduates.” Journal of Applied Philosophy (UK).
“Subroto Roy’s Philosophy of Economics is a formidable contribution…. The author’s aim is to steer a middle course between scepticism and dogmatism in his account of the knowledge we can have of economic phenomena, and in this he largely succeeds. The result is a most distinguished and valuable exploration of the nature of economic inquiry.” John Gray, Economic Affairs (UK).
“Interesting and well-written. Definitely worthwhile being read by any economist interested in the philosophical foundations of his subject and profession.” Journal of Institutional & Theoretical Economics (Germany).
“Roy’s basic argument is that the theory of economic knowledge underlying the work of most economists is logically inconsistent… The inconsistency lies in not permitting the skepticism that undermines the analysis of normative problems to destroy the logical foundation underlying positive analysis….. This well-documented study is a worthwhile contribution to the burgeoning literature on the philosophy of economics.” Choice
“The central argument of the book shows that the skepticism/dogmatism choice is a false dichotomy, that one need not embrace dogmatism in order to have objectivity or give up objectivity for freedom…. In the final section of the book Roy applies his critique… to several debates in economics. Chapter 8 presents the development of macroeconomics from John Maynard Keynes to the present through a dialogue between economists of opposing schools… Chapter 9 is a rich, wide-ranging discussion of mathematical models in economics…. Chapter 10 discusses the foundations of welfare economics… Roy shows how philosophical mistakes can lead economic thought astray, even though some of his arguments are also unsound. As a philosopher I find it encouraging to see an economist apply recent developments in epistemology to economic debates.” Journal of Economic History

“(Roy’s) message is for his fellow economists, urging them not to shy away from the treatment of normative issues in their discipline.” –Economics and Philosophy
“When Roy refers to the present received theory of economics, he means that this is the view not only of Chicago, but also of Cambridge, Massachusetts, and Cambridge, England, of Friedman, Samuelson, Myrdal, Hayek, and Joan Robinson. His coverage is broad…. In one place he states that it is precisely because it is possible for even a unanimous group of experts to be wrong that we have a reason, an objective reason, why freedom is to be valued. ‘Freedom is necessary for objectivity.’…. Whether one agrees or disagrees, one has to be impressed by the knowledge and sophistication involved in Roy’s presentation. Involved here is no run-of-the-mill carping at the economics establishment. This is a serious thoughtful work.” Social Science Quarterly
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.)
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.)
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.
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 http://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.
