there are no economic goods, but those the disposable supply of which is, at most, equal to the quantity that is required. But is not the largest navigable stream, even in the most thinly populated country, an economic good? _ 66 Hegel_, Rechtsphilosophie, § 67. Even the use of a corpse as manure, or for any mercantile purpose, is repugnant to our feelings, “because of the dignity of personality.” (_Schäffle_, National Œkonomie, 1860, 28.) In this respect, prostitution is a remnant of slavery. _Schäffle_ is right, when he says that to repay personal services with material commodities which do not afford as much food etc., as the former have cost in expenditure of vital energy, is a slow and frequently a very cruel kind of cannibalism. (Kapitalismus und Socialismus, 1870, 18). _ 67 Bornitz_, De rerum Sufficientia in Republica procuranda, 1625, gives in this encyclopædia of political science, together with a dissertation on agriculture, commerce and manufactures, a complete survey of the _ministeria_. Several modern writers refuse to look upon personal services, or the ability to render such services, as elements of wealth: compare _Kaufmann_, Untersuchungen im Gebiete der politischen Œkonomie, 1830, II, Heft I. They demonstrate, however, no more than this, that that class of goods has something very peculiar. Thus _Malthus_, Principles of Political Economy (1820), chap. I, sect. I, objects that they cannot be inventoried or taxed; but can material goods be so completely? Can all the parts of the wealth of a nation be so inventoried and taxed? _Rau_, Lehrbuch der pol. Œkonomie (1826) I, § 46, remarks that the personal aptitude to perform services dies with the person, and that personal services cannot be stored up (?), etc. I appeal simply to the definition I have given above of economic goods, and which applies equally to services of every kind which can be performed for other people. Besides, those who oppose this view are unable to give a satisfactory explanation of all the phenomena of commerce. Of course, the qualification “recognized as useful” is of the utmost importance as a mark to determine what is goods. But a prima donna, or a world-renowned physician, cast naked by shipwreck on the shores of North America, is certainly, better off than a blind beggar, his fellow sufferer. Compare _Storch_, Handbuch II, 335 ff. and his Considérations sur la Nature du Revenu National.
