未保持的

This practice is still retained among the wild and uncultivated nations that have never been formed into civil states, like the Tartars and others in the east; where the climate itself, and the boundless extent of their territory, conspire to retain them still in the same savage state of vagrant liberty, which was universal in the earliest ages; and which Tacitus informs us continued among the Germans till the decline of the Roman empire.7 We have also a striking example of the same kind in the history of Abraham and his nephew Lot.8 When their joint substance became so great, that pasture and other conveniences grew scarce, the natural consequence was that a strife arose between their servants; so that it was no longer practicable to dwell together.

这种行为方式仍然保留在那些野蛮无教养的未形成世俗政府的国家之中，比如鞑靼人和其他的东方人；在这些地方气候本身，以及他们领土的无边界性，共同促使他们仍然停留在漂泊自由的野人状态，这在最初的时代是普遍的情形；塔西特斯(56～120？)告诉我们杰曼人（German，常译为日尔曼，我不知道究竟是音译呢，还是意译，或许源于其它语言？）的这种状态一直保持到罗马帝国的衰落。这种情况，我们还有一个明显的例子，即历史上的亚伯拉罕和他的外甥罗得。
