The man scarce lives who is not more credulous than he ought to be... The natural disposition is always to believe. It is acquired wisdom and experience only that teach incredulity, and they very seldom teach it enough.
Adam SmithBoth ground- rents and the ordinary rent of land are a species of revenue which the owner, in many cases, enjoys without any care or attention of his own. The annual produce of the land and labour of the society, the real wealth and revenue of the great body of the people, might be the same after such a tax as before. Ground-rents, and the ordinary rent of land are, therefore, perhaps the species of revenue which can best bear to have a peculiar tax imposed upon them.
