"The bond price, and, as an arithmetical and rigid consequence, the interest rate is an inherently restless variable."

“A discipline, a region of the world of thought, should seek to know itself. Like an individual human being, it has received from its origins a stamp of character, a native mode of response to the situations confronting it. Right responses, 'responsibility', will require of the profession as of the individual an insight into the powers and defects of the tool which history has bequeathed to it.”

“In the Treatise we are shown the bond-market as it exists in real life: a speculative market where a price, with an identity and a momentary stability, can only exist if there are two camps of dealers holding opposite views of the impending movement of bond prices.”

“Whatever form it takes, the possession of the imaginative gift transforms the problem of accounting for human conduct. For now it is not a question of how given needs are satisfied. Deliberative conduct, choice, the prime economic act, depend for their possibility, when they go beyond pure instinctive animal response to stimulus, upon the conceptual power of the human mind. Choice is necessarily amongst thoughts, amongst things imagined.”

“Myrdalian ex ante language would have saved the General Theory from describing the flow of investment and the flow of saving as identically, tautologically equal, and within the same discourse, treating their equality as a condition which may, or not, be fulfilled”

“When we examine this suggestion, we see that it is no more than a formal acknowledgement of a problem, the problem of how the equilibrium prices are to be discovered. Repeated trial and error, while the market stands in suspense awaiting the outcome, is not a practical resort. The number of distinct trials, even if confined to discrete steps of price and quantity, would be so immense that the necessary 'market day' would extend beyond human life-times... theoretical ideal applies to mutually isolated days or moments, each to be treated as perfectly self-contained and looking to no yesterday and no tomorrow. But the real market is dealing with goods inherited from yesterday, and in means of production whose products will not be ready till tomorrow. Meanwhile the non-economic circumstances are changing and rendering each successive equilibrium obsolete.”

“There is little point in demanding minor concessions and relaxations of the abstract, timeless general equilibrium. The light it can throw on human affairs is throw by its most austere and formal version. We are not concerned to ask: How could it possibly work? The useful question is: What does its logical structure imply?”
