Why do people still value fiat money? Part II

Image result for Isaac Newton

Yesterday, I began a discussion of the work of  Professor Guillermo Calvo, now of Columbia University’s School of International and Public Affairs, in an effort to answer the question in the headline of this blog entry, and I got so far as to introduce the word "stickiness." Let's proceed from there.

Calvo does acknowledge that fiat money contains within itself the principle of its own destruction. But ... why does its destruction take so long? Even if deliberate government buttressing of the use of its money were "completely absent," he says, this factor would slow the aforementioned destruction. 

Stockiness is simply a convenient name for the behavioral fact that suppliers of goods and services "broadcast, far and wide, their willingness to take fiat money in exchange" for what they are selling. Further, private sellers often "reaffirm their willingness to do so over extended periods of time."

The suppliers find it useful as a marketing matter to advertise this commitment, and the buyers find it useful to rely upon such commitments. The fiat money is the focal point of this utility on both sides, and that will be difficult to change. Thus, gold "may not succeed in debunking the US dollar ... unless gold becomes a unit of account and, more to the point, a substantial share of prices and wages are quoted in terms of gold."

The threat to fiat money these days arises from the cryptocurrencies, not from gold. Still, the same argument applies. There is a powerful institutional inertia implicit in the existing system.

Inertia that would even impress the fellow pictured above.

Great Chain of Being

One of the points that Lovejoy makes in the book of that title I mentioned last week is the importance, in the Neo-Platonist conceptions and in the later development of the "chain of being" metaphor, of what he calls the principle of plenitude. This is the underlying notion that everything that can exist must exist, that creation would not be possible at all were it to leave gaps.

The value of this idea for a certain type of theodicy is clear enough.

This caused theological difficulties when these ideas were absorbed into Christianity.  I'll quote a bit of what Lovejoy has to say about those difficulties:

"For that conception, when taken over into Christianity, had to be accommodated to very different principles, drawn from other sources, which forbade its literal interpretation; to carry it through to what seemed to be its necessary implications was to be sure of falling into one theological pitfall or another."

The big pitfalls were: determinism on the on…

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.

We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a majestic wate…
