All who have read “Robinson Crusoe” (and who has not?) will remember the circumstance of his opening, some time after he had become domiciled on his desolate island, one of the chests that had come to him from the ship. In it he found pins, needles and thread, a pair of large scissors, “ten or a dozen good knives,” some cloth, about a dozen and a half of white linen handkerchiefs concerning which he remarks, “They were exceedingly refreshing to wipe my face on a warm day;” and, finally, hidden away in the till of the chest, “three great bags of money—gold as well as silver.”

The finding of all these articles—the money excepted—it will be further remembered, greatly delighted the heart of Crusoe; inasmuch as they increased his store of useful things, and therefore increased his comfort and happiness. But in respect to the money the case was entirely different. It was a thing to him, under the circumstances, absolutely worthless, and over its presence and finding he soliloquized as follows: “I smiled at myself at the sight of all this money. ‘Oh, drug!’ said I, aloud, ‘what art thou good for? Thou art not worth to me, no, not the taking off the ground. One of these knives is worth all this heap. Nay, I would give it all for a gross of tobacco-pipes; for sixpenny-worth of turnip and carrot seed from England; or for a handful of pease and beans, and a bottle of ink.’”

In introducing this episode in the life of his hero, nothing was probably further from the thought of the author, De Foe, than the intent to give his readers a lesson in political economy. And yet it would be difficult to find an illustration which conveys in so simple a manner to him who reflects upon it so much of information in respect to the nature of that which is popularly termed “wealth;” or so good a basis for reasoning correctly in respect to the origin and function of that which we call “money.” And in such reasoning, the truth of the following propositions is too evident to require demonstration:

1st. The pins and needles, the scissors, knives, and cloth were of great utility to Robinson Crusoe, because their possession satisfied a great desire on his part to have them, and greatly increased his comfort and happiness.

2d. Possessing utility, they nevertheless possessed no exchangeable value, because they could not be bought or sold, or, what is the same thing, exchanged with any body for any thing.

3d. They had, moreover, no price, for they had no purchasing power which could be expressed as money.

4th. The money, which is popularly regarded as the symbol and the concentration of all wealth, had, under the circumstances, neither utility, value, nor price. It could not be eaten, drunk, worn, used as a tool, or exchanged with any body for any thing, and fully merited the appellation which Crusoe in another place gives it, of “sorry, worthless stuff.”

Finally, the pins, needles, knives, cloth, and scissors were all capital to Robinson Crusoe, because they were all instrumentalities capable of being used to produce something additional, to him useful or desirable. The money was not capital, under the circumstances, because it could not be used to produce any thing.

Starting, then, with a condition of things on the island in which money had clearly neither utility nor value, let us next consider under what change of domestic circumstances it could become useful, acquire value, become an object of exchange, and constitute a standard for establishing prices.
