injurious, is useful, if the desire of it causes productive labour in other directions.
52. In the national store, therefore, the presence of things intrinsically valueless does not imply an entirely correlative absence of things valuable. We cannot be certain that all the labour spent on vanity has been diverted from reality, and that for every bad thing produced, a precious thing has been lost. In great measure, the vain things represent the results of roused indolence; they have been carved, as toys, in extra time; and, if they had not been made, nothing else would have been made. Even to munitions of war this principle applies; they partly represent the work of men who, if they had not made spears, would never have made pruning-hooks, and who are incapable of any activities but those of contest.
53. Thus then, finally, the nature of the store has to be considered under two main lights; the one, that of its immediate and actual utility; the other, that of the past national character which it signifies by its production, and future character which it must develope by its use. And the issue of this investigation will be to show us that.
