give poor nations an advantage over rich ones; or, at least, tend to raise the one and draw down the other. Though we find, from the history of the various revolutions that have taken place in different countries, that they arose from a variety of causes, some peculiar to one nation, and some to another; yet we have found a change of manners and ways of thinking and acting, more or less operating in all of them. Amongst the interior causes of the decline of wealthy nations, arising from the wealth itself, we must set this down as one of a very general and natural operation. We must be particularly careful to remove this, as far as possible, if we mean to avert those evils which hitherto have arisen from a superior degree of wealth and power in every nation. We are now going to examine other internal causes; but though they are separate from this, yet this is at the root of all, this is perpetually operating, we meet with it in every corner and at every turning. It is what Mr. Pope says, speaking of the master-passion in individuals: "The great disease that must destroy at length, Grows with our growth, and strengthens with our strength." This radical case of decline is augmented by an ill conceived vanity in the parents, as well as by necessity ceasing to act on the children. Each is following a very natural inclination; the one to indulge, the other to be indulged. It is the duty and the interest of the state to counteract this tendency, and the manner how that it is to be done will be inquired into in the first chapter of the third book of this work. =sic --there is none.= But it is not merely a neglect of industry and the means of rising in society, or keeping one's place in it that is hurtful; the general way of thinking and acting becomes different, and, by degrees, the character of a nation is entirely altered. This change was the most rapid, and the most observable in the Roman republic, and was the cause that brought it to an end, and prepared the people for submitting to be ruled by the emperors. The human character was as much degraded under them, when the citizens were rich, as it ever had been exalted under their consular government, when the people were indigent. [end of page #90] The various effects of this change in manners will be considered under different heads, but it is too deeply rooted in human nature ever to be entirely counteracted, much less entirely done away. It is firmly connected with the first principles of action in man, and can no more be removed than his entire nature can be altered. What is in the extreme, if dangerous, may be diminished; and that is all that it would be any way useful to attempt: it may be rendered less formidable in its operation, and that is all that can be expected.
