201:." The things which have the greatest value in use have frequently little or no value in exchange; on the contrary, those which have the greatest value in exchange have frequently little or no value in use. Nothing is more useful than water: but it will purchase scarcely anything; scarcely anything can be had in exchange for it. A diamond, on the contrary, has scarcely any use-value; but a very great quantity of other goods may frequently be had in exchange for it.

However, since water is in such large supply in the world, the marginal utility of water is low. In other words, people feel less urgency or enjoyment from consuming water since they know that water would continue to exist. Thus, consuming an extra unit of water would not generate an extra unit of usefulness and thus, an extra willingness to pay for it.
264:
Therefore, any particular unit of water is worth less to people as the supply of water increases. On the other hand, diamonds are in much lower supply. They are of such low supply that the usefulness of one additional diamond is greater than the usefulness of one additional glass of water, which is
256:
So, the value of the fifth bag of grain is equal to the satisfaction he gets from feeding the pigeons. If he sells that bag and neglects the pigeons, his least productive use of the remaining grain is to make whisky, so the value of a fourth bag of grain is the value of his whisky. Only if he loses

With the first, he will make bread to survive. With the second, he will make more bread, in order to be strong enough to work. With the next, he will feed his farm animals. The next is used to make whisky, and the last one he feeds to the pigeons. If one of those bags is stolen, he will not reduce
260:
In explaining the diamond-water paradox, marginalists explain that it is not the total usefulness of diamonds or water that determines price, but the usefulness of each unit of water or diamonds. It is true that the total utility of water to people is tremendous, because they need it to survive.
192:
What are the rules which men naturally observe in exchanging them for money or for one another, I shall now proceed to examine. These rules determine what may be called the relative or exchangeable value of goods. The word VALUE, it is to be observed, has two different meanings, and sometimes
213:
Hence, Smith denied a necessary relationship between price and utility. Price on this view was related to a factor of production (namely, labor) and not to the point of view of the consumer. Proponents of the labor theory of value see that as the resolution of the paradox.

in abundant supply. Thus, diamonds are worth more to people. Therefore, those who want diamonds are willing to pay a higher price for one diamond than for one glass of water, and sellers of diamonds ask a price for one diamond that is higher than for one glass of water.
226:
At low levels of consumption, water has a much higher marginal utility than diamonds and thus is more valuable. People usually consume water at much higher levels than they do diamonds and thus the marginal utility and price of water are lower than that of
245:. The marginal utility of a good is derived from its most important use to a person. So, if someone possesses a good, they will use it to satisfy some need or want, starting with the one that takes highest priority.

Conversely, a man dying of thirst in a desert would have greater marginal use for water than for diamonds so would pay more for water, perhaps up to the point at which he was no longer dying.

Water is a commodity that is essential to life. In the paradox of value, it is a contradiction that it is cheaper than diamonds, despite diamonds not having such an importance to life.

A colonial farmer, whose log hut stands by itself in the primeval forest, far away from the busy haunts of men, has just harvested five sacks of corn...

This 'paradox of value', as it was called, was frequently noted before Adam Smith (for example, by
Copernicus who wrote a bit on economic questions)...
