The complete economist, on Shackle's mischievous accounting, would need mathematics, philosophy, psychology, anthropology, history, geography, politics, prose, and practical finance all at once—an impossible portrait meant to show that no single technique defines the field. Theory, he argues, is the disciplined imaginative construction of recurrent structures; it grows rigorous not by turning algebraic but by drawing out implications and testing them against rival forms. Keynes stands as proof, since abler mathematicians produced no revolution of their own. From this breadth follows an educational program: recruit able rather than residual students, delay premature specialization, and keep mathematics the servant of economic problems. An economist, on this view, is formed by breadth disciplined into judgment—the capacity to quantify without forgetting the people economics is finally about.

Economics emphatically is about chaps.

What should economics gain from measurement—and what should it refuse to surrender to the promise of exact prediction? In this 1954 review of Jan Tinbergen’s Econometrics, G. L. S. Shackle distinguishes indispensable numerical description from forecasting ambitions whose reliability he questions. His concern is also educational: making advanced econometrics the dominant form of postgraduate research could crowd out historically and philosophically informed inquiry, and students whose gifts are not mathematical. Yet his judgement of Tinbergen’s book is appreciative. Its accessible explanations offer non-specialists a way to understand quantitative methods without becoming practitioners. The review’s interest lies in this combination: Shackle defends statistical knowledge while challenging the institutional authority claimed for predictive modelling.

Originality need not mean abandoning inherited tools: that is Shackle’s judgement of J. E. Meade’s A Geometry of International Trade in this short review. Familiar curves and price lines, meticulously drawn, can make the effects of taxes, subsidies and changing market conditions intelligible within a two-country, two-commodity model. Shackle specifies their achievement as qualitative insight—showing directions of adjustment rather than supplying numerical answers. His distinctive interest lies in the connection between analytical precision and visual craftsmanship: a well-placed label or clearly distinguishable curve helps students see economic relationships. The review offers a compact account of why exposition can itself be an intellectual achievement, and why apparently forbidding diagrams may become lucid once readers learn where to look.

What should an economics textbook explain rather than take for granted? In this brief review of F. Zeuthen’s Economic Theory and Method, G. L. S. Shackle defends methodological reflection as part of a student’s education, not a preamble to skip. He values Zeuthen’s account of Walrasian interdependence and the annotated references that lead readers into original research. Yet his praise leaves room for precise objections: counting equations and unknowns does not settle determinacy, and orthodox dynamics still resembles temporary huts beside a ruined static Acropolis. The review offers a compact view of Shackle’s standards for theoretical teaching—clarity without intellectual shortcuts—and his suspicion that economics has yet to reckon adequately with time.

In this brief reply to Gould, Shackle offers an endorsement rather than a counterargument: he praises Gould’s reasoning and supports the directions of inquiry proposed. Its interest lies in the research priority Shackle states with unusual directness—decision-making as perhaps the richest and most central problem in the human sciences. The note records that commitment and agreement without elaborating a theory or specifying the methods by which inquiry should proceed.

When do long odds make an outcome seem not merely improbable but impossible? In this brief reply to Gould, Shackle acknowledges a difficulty for his account of decision under uncertainty: even someone facing a unique venture may let probabilities shape judgements of what can happen. He welcomes investigation of Gould’s proposed modification while insisting on a prior question—whether the conflicting evidence from which businesspeople form expectations can be expressed as numerical odds at all. The exchange offers a compact view of Shackle responding to criticism without abandoning his central distinction between probability and possibility, and helps readers separate two sources of uncertainty: the rarity of a decision and the difficulty of interpreting its evidence.

Calculation can find an optimum, but can it tell us which rule of choice to adopt under uncertainty? In this review of Boulding and Spivey’s volume, G. L. S. Shackle pairs admiration for mathematical clarity with resistance to making technique a complete account of economic decision. He praises Spivey’s lucid exposition and welcomes Boulding’s challenge to a single standard of rational behaviour. His distinction between describing an optimum and providing a convenient numerical route to it gives mathematical programming practical credit without granting it a conceptual revolution. The review offers a compact encounter with Shackle’s critical perspective: mathematics deserves precision and respect, while decisions, methodological claims, and editorial choices remain open to judgement.

Can it be that Professor BOULDING is here using the word *decision* to mean something other than the doing of sums and reading off the answer?

The ruin in Shackle’s title is the loss of confidence in an economy that automatically reconciles private interests—not the end of economics. This 1961 article asks what the discipline should teach once unemployment, imperfect competition and inflation have unsettled that reassuring picture. Shackle brings personal experience to the question, recalling how hearing Joan Robinson in Cambridge transformed his understanding of unemployment. He also argues that Keynes and Hayek addressed different conditions: deficient demand and excessive investment under full employment. His perspective combines respect for mathematical tools with resistance to treating people as calculating machines. Readers can discover how a critique of automatic harmony becomes a concrete proposal for economic education, linking resource allocation to employment, monetary authority and the political choices that theory cannot settle alone.

Much recent work in economics has treated man as a computer. Let us also study him as an artist, a poet, a mystic, a dreamer, in some degree, even in his economic activity.

Shackle opposes reason to imagination and probability to poetry, without discarding knowledge: business policy, he argues, is an originative art conducted under radical uncertainty, not the solving of a well-posed problem. He builds a scale of openness from dice and cards, which yield a complete list of outcomes, through horse-racing to new enterprise, which has no card of runners and no book of rules. Decision is commitment to a future that does not yet exist, and therefore choice among imagined possibilities rather than known facts. Where probability demands an exhaustive list of contingencies, he substitutes judgments of possibility, surprise, and ascendancy, with focus-gain and focus-loss standing for an enterprise in deliberation. Success, he concludes, needs not only the axial mind that reasons toward a solution but the radial imagination that sees outward into an expanding field of possible histories.

My first proposition is that decision is choice amongst the products of imagination.

Money lets its holder postpone a purchase—but what place can postponement have in a theory where all choices are already reconciled? In this article, first published in 1972 and reprinted here in 1988, G. L. S. Shackle weighs marginalism’s achievements against its exclusion of historical time. He shows how marginal analysis turns diverse private valuations into common market measures, while arguing that demonstrably optimal choice requires knowledge unavailable to people facing an uncertain future. His perspective is neither a rejection of equilibrium nor a defence of its universal reach: its coherence illuminates economic relationships without reproducing the predicament of actual decision-makers. Money makes the distinction concrete, allowing readers to see why a framework that explains prices and distribution can struggle to explain the freedom to wait.

One unfinished project links Keynes's Treatise on Money and his General Theory: the attempt to make economics adequate to a future no agent can know. Shackle finds the sharpest tool not in the General Theory but in the Treatise's Fundamental Equations, which he reads as rudimentary sequence analysis—income as anticipated cost, profit as the gap between what was expected and what occurred. From this ex ante/ex post distinction he rebuilds liquidity preference and the marginal efficiency of capital as phenomena of speculative markets, confidence, and mood, not as stable schedules. Economic life becomes kaleidic: neither a march toward equilibrium nor a regular cycle, but a succession of temporary patterns that shifting expectations can shatter in an instant, leaving resources idle as asset-holders retreat into liquidity.

Income, in the Fundamental Equations, is a conjecture which can be wrong.

Thought is the only thing directly known, and its passing is the raw experience from which time itself is abstracted—an unlikely starting point for a theory of choice, and a deliberate one. Shackle builds from it a critique of deterministic economics: if choice genuinely matters, it must be a beginning, an uncaused cause, a taking-place not already implicit in its antecedents, and its sequels cannot be a ready-made list waiting to be ranked. Possibility, for the chooser, becomes the absence of discernible fatal obstacles rather than a measurable frequency; commitment, not calculation, is the vital act, staking self-esteem on imagined outcomes. Marshalling potential surprise, ascendancy, and focus-gain against frequency probability, he makes investment the exemplary economic act—a symbolic wager on a future whose outcomes can never be exhaustively listed.

Possibility, for the chooser, is the absence of discernible fatal obstacles.
