I do think that in the free tenure of land, the fixed obligations of allodialism, the relation of the freeman to history as the impersonation of the race, the combination of the frankpledge, nay, I will add the compurgation and the ordeal and the wergild, is to be found a more likely basis of freedom than in the community of land, the close tie of patriarchal or family unity, the enormous and disproportionate estimate of blood nobility, and the clannish spirit that one finds in the Highland Scot and Irishman, or in the Pole or Hungarian.

Among the first truths which the historical student, or indeed any scientific scholar, learns to recognise, this is perhaps the most important, that no theory or principle works in isolation.
