Inflation may be defined as any increase in the economy's supply of money not consisting of an increase in the stock of the money metal.

Inflation is taxation without representation.

Five simple truths embody most of what we know about inflation: Inflation is a monetary phenomenon arising from a more rapid increase in the quantity of money than in output (though, of course, the reasons for the increase in money may be various). In today’s world government determines — or can determine — the quantity of money. There is only one cure for inflation: a slower rate of increase in the quantity of money. It takes time — measured in years, not months — for inflation to develop; it takes time for inflation to be cured. Unpleasant side effects of the cure are unavoidable.

Inflation is a simple idea: imagine that the universe begins in a tiny patch of space dominated by the potential energy of some scalar field, a kind of super-dense dark energy. This causes that patch to expand at a terrifically accelerated rate, smoothing out the density and diluting away any unwanted relics. Eventually the scalar field decays into ordinary matter and radiation, reheating the universe into a conventional Big Bang state, after which things proceed as normal.

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.

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.

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

Mere inflation-that is, the mere issuance of more money, with the consequence of higher wages and prices-may look like the creation of more demand. But in terms of the actual production and exchange of real things it is not.

Inflation is always and everywhere a monetary phenomenon.

Inflation is a prequel to the conventional Big Bang theory. ...It does provide a theory of the propulsion that drove the universe into this humungous episode of expansion which we call the Big Bang.

Inflation is the unhappy result of our monetary mismanagement and the ultimate cause of the coming economic collapse.

It is not easy to see relationships always in terms of real goods and real welfare. Who among us does not feel richer and prouder when he is told that our national income has doubled (in terms of dollars, of course) compared with some preinflationary period? Even the clerk who used to get $75 a week and now gets $120 thinks that he must be in some way better off, though it costs him twice as much to live as it did when he was getting $75. He is of course not blind to the rise in the cost of living. But neither is he as fully aware of his real position as he would have been if his cost of living had not changed and if his money salary had been reduced to give him the same reduced purchasing power that he now has, in spite of his salary increase, because of higher prices. Inflation is the autosuggestion, the hypnotism, the anesthetic, that has dulled the pain of the operation for him. Inflation is the opium of the people.

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.

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.
