Each of these groups of men camps about a common centre, and kingdoms appear.

The social instinct succeeds the nomadic instinct.
The camp gives place to the city, the tent to the palace, the ark to the temple.

The chiefs of these nascent states are still shepherds, it is true, but shepherds of nations; the pastoral staff has already assumed the shape of a sceptre.

Everything tends to become stationary and fixed.

Religion takes on a definite shape; prayer is governed by rites; dogma sets bounds to worship.
