SECTION II
THE MORALITY OF PRIVATE CAPITAL AND INTEREST
CHAPTER IX
THE NATURE AND THE RATE OF INTEREST
Interest denotes that part of the product of industry which goes to the capitalist. As the ownership of land commands rent, so the ownership of capital commands interest; as rent is a price paid for the use of land, so interest is a price paid for the use of capital.
However, the term capital is less definite and unambiguous, both in popular and in economic usage, than the word land. The farmer, the merchant, and the manufacturer often speak of their land, buildings, and chattels as their capital, and reckon the returns from all these sources as equivalent to a certain per cent. of interest or profit. This is not technically correct; when we use the terms capital and interest we should exclude the notions of land and rent.
