Pacific.(374) But it is most especially, large, well-watered plains that are best adapted to the construction of roads, and thus to facilitate the division of labor. And while we find, in many countries, that the mountainous regions reached a certain stage of development earlier than any others, because they were more easily protected by military force, we find, too, that even here, plains, have, for the most part, had the largest share of power and of civilization (northern Italy, northern France, the plains of Switzerland and north Germany). See § 36.(375) We must not, however, fail to consider the reverse side of the picture of the great highways of the world. The same reasons that raise them to the dignity of lines of commerce, make them lines of war; and even the contagion of great plagues and of the ruling vices follows, as a rule, the avenues of trade. Section LXII. The Reverse, Or Dark Side Of The Division Of Labor. There are hardships often attending the highly developed division of labor, the dark and bright sides of which are most strikingly observable only in large cities. However, when it is charged with adding to the natural inequality of men, the accusation can be met only by the answer, that, without the division of labor, we should be all equally poor and equally coarse; for each one would be absorbed by the necessity of providing for his lower wants, and no one would be in a way to develop his higher faculties. Even the poorest man has more enjoyment in consequence of the division of labor, than he could have living in a state of isolation from his fellow men. The most wretched among us, the invalid without property of any kind, the father of a family with more children than he can support, would simply starve in the primeval forest.
