According to this doctrine, the desire for wealth cannot be satiated. The millionaire would still choose an extra half-crown rather than refuse it, although the half-crown brings him incomparably less additional pleasure than it brought him when his pockets were empty. But it is also true that long before we were millionaires, the pleasure obtainable by additional wealth may be infinitesimal, or absolutely non-existent. The simple desires may be easily saturated. Pope asks, "What riches give us, let us then inquire". And he replies, "Meat, fire, and clothes--what more? Meat, clothes, and fire." This is, in fact, a pithy summary of our most elementary and necessary wants. Now, our demand for meat is obviously strictly limited. As soon as we have eaten, say, a pound of beefsteak, we do not want more; by the time we have eaten, say, three pounds we do not only not want more, we loathe the very thought of eating. So, when we are clothed sufficiently for comfort and decency, more clothing is simply a burden; and we wish only for so much fire as will keep our thermometer within certain limits; a heat above or below would mean death either by burning or by freezing. Our ultimate aim, therefore, in regard to desires of this class, is not to increase the stimulus indefinitely, but to preserve a certain balance or equilibrium. If we want more food after our appetites are satisfied, it must either be with a view to our future consumption, which is still strictly finite, or else with a view to exchanging the food for something else, in which case it is desired, not as food, but as the means of satisfying some other desire. If, then, Pope's doctrine were really sound, which actually amounts to saying, if our desires were really limited to the physical conditions necessary to life, we should very soon reach the state in which they would be completely glutted or saturated. It may be worth while to note the circumstance which rather obscures our recognition of this fact. We may distinguish between the wealth which a man actually uses and that which remains, as I may say, only potential. A man may desire an indefinite quantity of wealth, because he may wish to have rights which he may yet never turn to actual account. There is a certain satisfaction, no doubt, in knowing that I have a vast balance at my banker's, though I have no desire to use it. I may want it some time or other; and, even if I never want it, I may enjoy the sense of having a disproportionate barrier of money-bags piled up between me and the yawning gulf of actual poverty. Therefore, though a very limited amount may be enough to satiate all our existing desires, we may like to know that there is more at our disposal. If possession carried with it the necessity of using our property, if we could not have potential as distinguished from actual wealth, we should be so far from desiring an indefinite increase of wealth that we should regard the
