Kinship has dethroned itself by its very success.

Thanks to the organizing power of kinship, primitive society has grown, and by growing has stretched the birth-tie until it snaps.

Some relationships become distant in a local and territorial sense, and thereupon they cease to count.

My duty towards my kin passes into my duty towards my neighbour.
* * * * * Reasons of space make it impossible to survey the further developments to which social organization is subject under the sway of locality.
It is, perhaps, less essential to insist on them here, because, whereas totemic society is a thing which we civilized folk have the very greatest difficulty in understanding, we all have direct insight into the meaning of a territorial arrangement; since, from the village community up to the modern state, the same fundamental type of social structure obtains throughout.
Besides local contiguity, however, there is a second principle which greatly helps to shape the social order, as soon as society is sufficiently advanced in its arts and industries to have taken firm root, so to speak, on the earth's surface.

This is the principle of private property, and especially of private property in land.
