It is not strange, of course, that things should assume a somewhat different aspect according to the point of view from which they are described. Legal classification need not go into details which may be very important for purposes of manorial administration; neither the size of the holdings nor the complex variations of services have to be looked to in cases where the law of status is concerned. Still it may be taken for granted that the distinctions and rules followed by the courts had to conform in a general way with matter-of-fact conditions. Lawyers naturally disregarded minute subdivisions, but their broad classes were not invented at fancy; they took them from life as they did the few traits they chose from among many as tests for the purpose of laying down clear and convenient rules. A general conformity is apparent in every point. At the same time there is undoubtedly an opposition between the _curial_ (if I may use that term) and the _manorial_ treatment of status and tenure, which does not resolve itself into a difference between broad principle and details. Just because the lawyer has to keep to distinct rules, he will often be behind his age and sometimes in advance of it. His doctrine, once established, is slow to follow the fluctuations of husbandry and politics: while in both departments new facts are ever cropping up and gathering strength, which have to fight their way against the rigidity of jurisprudence before they are accepted by it. On the other hand, notions of old standing and tenacious tradition cannot be put away at once, so soon as some new departure has been taken by jurists; and even when they die out at common law such notions persist in local habits and practical life. For these reasons, which hold good more or less everywhere, and are especially conspicuous in mediaeval history, the general relation between legal and manorial documents becomes especially important. It will widen and strengthen conclusions drawn from the analysis of legal theory. We may be sure to find in thirteenth-century documents of practical administration the foundations of a system which prevailed at law in the fifteenth. And what is much more interesting, we may be sure to find in local customaries the traces of a system which had its day long before the thirteenth century, but was still lingering in broken remains.
