Some writers have asserted that the king's thanes were the nobles, and that the others were simple freemen. An attentive examination of Anglo-Saxon institutions will prove that there was no such difference of position and rights between the two classes. It is a great error to expect to meet with clearly defined ranks and conditions, at the origin of society. Some writers, however, pretend to discover at the outset what time alone can introduce. We meet with no nobility, constituting a superior social condition, with recognized privileges: we perceive only the causes which will progressively form a nobility, that is, will introduce inequality of power and the empire of the strong.
