What is it that happens in an inflation? The unit of money suddenly loses its identity. The crowd it is part of starts growing and, the larger it becomes, the smaller becomes the worth of each unit. The millions one always wanted are suddenly there in one's hand, but they are no longer millions in fact, but only in name.

Inflation is always and everywhere a monetary phenomenon in the sense that it is and can be produced only by a more rapid increase in the quantity of money than in output. … A steady rate of monetary growth at a moderate level can provide a framework under which a country can have little inflation and much growth. It will not produce perfect stability; it will not produce heaven on earth; but it can make an important contribution to a stable economic society.

Money is a wonderful thing. It started out in human history as hard currency, generally gold or silver. These are commodities that are deemed to have intrinsic value but also act as a means of abstractly representing wealth accumulated out of other real commodities. Relatively little hard currency ever circulated freely in the preindustrial world. In that world, most wealth was actual, existing in the form of land, palaces, fleets of boats, bolts of cloth, barrels of grain, standing timber, herds of cattle, and so forth. These were generally things that could be traded, and exchanges of these items were often facilitated through the medium of gold or silver, hence the term "medium of exchange." [The] hard currency could also be acquired by theft or plunder, though that did not necessarily affect its value. Note that the value of [the] hard currency is transcultural. Gold and silver had high value to the Europeans, the Chinese of the Sung dynasty, the Inca, the Aztecs, the ancient Egyptians, and the California Forty-niners.
The industrial experiment took the idea of currency (money) to the next level of abstraction—as hard currency can represent actual goods, so paper currency can represent hard currency and actual goods. As trade increased and took place over ever-greater distances, paper promises to pay hard currency began to steadily take the place of the hard stuff itself, which was cumbersome, hard to lug around in large quantities, and subject to theft in transit. So, to streamline these trades, all kinds of certificates were used as equivalents to hard currency: individual IOUs, bills of lading, letters of credit from rich people, [and] promissory notes issued by guilds. In time, the use of paper certificates became… more normative and conventionalized. Protocols of exchange were established. Institutions were created to process them. This process of managing monetary affairs—of wealth abstracted in [a] paper—was called finance.

Under the influence of ignorance and custom, the day's pay of a country labourer will remain for a long time at a franc, while the saleable price of all the articles of consumption around him will be rising. He will sink into destitution without being able to discover the cause. In short, since you wish me to finish, I must beg you, before we separate, to fix your whole attention upon this essential point: — When once false money (under whatever form it may take) is put into circulation, depreciation will ensue, and manifest itself by the universal rise of every thing which is capable of being sold. But this rise in prices is not instantaneous and equal for all things. Sharp men, brokers, and men of business, will not suffer by it; for it is their trade to watch the fluctuations of prices, to observe the cause, and even to speculate upon it. But little tradesmen, countrymen, and workmen, will bear the whole weight of it. The rich man is not any the richer for it, but the poor man becomes poorer by it. Therefore, expedients of this kind have the effect of increasing the distance which separates wealth from poverty,

Once false money (under whatever form it may take) is put into circulation, depreciation will ensue, and manifest itself by the universal rise of everything that is capable of being sold. But this rise in prices is not instantaneous and equal for all things.

Inflation is an increase in the quantity of money without a corresponding increase in the demand for money, i.e., for cash holdings.

Inflation is always and everywhere a monetary phenomenon.

By a continuing process of inflation, government can confiscate, secretly and unobserved, an important part of the wealth of their citizens. By this method they not only confiscate, but they confiscate arbitrarily. . . . As the inflation proceeds and the real value of the currency fluctuates wildly from month to month, all permanent relations between debtors and creditors, which form the ultimate foundation of capitalism, become so utterly disordered as to be almost meaningless; and the process of wealth-getting degenerates into a gamble and a lottery.

Inflation is caused by a continuing surfeit of money; inflation can therefore be controlled or prevented only by striking at the source of money surfeit. It follows that all prices and incomes policies are irrelevant and futile, whether they are voluntary or compulsory. If the surfeit of money continues, then all prices and incomes must rise accordingly.

I well remember the time, after the First World War, when one needed a tillion-mark note to buy a dozen eggs. Since paper, however, was still valuable, the bank notes were stored in gigantic silos which stood in the yards of our factories. In these we children made tunnels and played among the billions and trillions — a strange introduction to money, but perhaps it helped me to realize how worthless it can become when man-made values change.

Inflation is caused by too much money chasing after too few goods.

From the time that money began to be regarded with honor, the real value of things was forgotten.

It would be hard nowadays to find a practitioner who upon being pressed did not confess to two main propositions: the disease of inflation in its modern form is caused by an exorbitant increase in money; and, secondly, that increase is caused by governments borrowing from the banking system in order to cover excess public expenditure.

The remarkable thing was that everyone accepted the entire process, seemingly as normal as physical laws of nature, despite the fact that it was really as ethereal as a rainbow. The money did not physically exist. Even “real” money was only specially made paper printed with black ink on the front and green on the back. What backed the money was not gold or something of intrinsic value, but rather the collective belief that money had value because it had to have such value.
