regard to particular circumstances. In general, we may say, that, in place of inviting the lower classes to pass their time in drinking, by the innumerable receptacles that there are for those who are addicted to that vice, every impediment should be put in the way. Drinking is a vice, the disposition to which grows with its gratification; most other avocations (for drinking in moderation is only such) have no tendency of the sort. Those enjoyments which have a tendency to degenerate into vice should be kept under some check; those which have no such tendency ought to be encouraged; for, where the main and general mass of the population of a country is corrupted, it is impossible to prevent its decline. If it remains uncorrupted, the matter is very easy, or, more properly, it may be said that prosperity is the natural consequence. Manners will always be found of more consequence than laws, and they depend, in a great measure, on the wise regulations of government in every country. Not only do most governments profit by laying the vices of the people under contribution; but, as revenue is, by a very false rule, taken as a criterion from which the prosperity of a nation may be estimated, the very evil that brings on decay serves to disguise its approach. A nation may be irretrievably undone, before it is perceived that it has any tendency to decline; it is, therefore, unwise for governments to wait till they see the effects of decay, and then to hope to counteract them; they must look before-hand, and prevent, otherwise all their exertions will prove ineffectual.

The external causes of the decline of nations are much more simple in themselves than the internal ones, besides which, their action is more visible; the way of operation is such as to excite attention, and has made them thought more worthy of being recorded. The origin of envy and enmity are the same. The possession of what is desirable, in a superior degree, is the cause of envy. That occasions injurious and unjust proceedings, and enmity is the consequence, though both originated in the same feeling at first, they assume distinct characteristics in the course of time. The desire of possession, in order to enjoy, is the cause of enmity and envy; and all the crimes of nations, and of individuals, have the same common origin. It follows, as a natural consequence, arising from this state of things, that those nations which enjoyed a superior degree of wealth, became the objects of the envy of others. If that wealth was accompanied by sufficient power for its protection, then the only way to endeavour to share it was by imitation; but if the wealth was found unprotected, then conquest or violence was always considered as the most ready way of obtaining possession.
