If these tendencies to excessive and sometimes ignorant praise have been unfortunate from one point of view, they have been most fortunate from another. The legal and political aspects must be sharply contrasted. On the one hand, the vague and inaccurate words used in speaking of the Charter even by great lawyers, such as Coke (not necessarily equally great as historians, living as they did in an age when the science of history was unknown), have not only obscured the bearing of many chapters, but have done a distinct injury to the study of the development of English law. On the other hand, as the mistakes made in commenting on the Charter have been almost entirely due to a laudable desire to extend as widely as possible its provisions in favour of individual and national liberties, and to magnify generally its importance; the service these very errors have done to the cause of constitutional progress is measureless. If political bias has coloured the interpretation placed on many of the most famous clauses, the ensuing benefit has accrued not to any one narrow party or faction, not to any separate class or interest, but rather to the entire body politic and to the cause of national progress in its widest and best developments. Thus the historian of Magna Carta, while bound to correct estimates now seen to be erroneous in the light of modern research, cannot afford to despise or under-estimate the value of traditional interpretations. The meanings which have been read into it by the learned men of later ages, and which have been acquiesced in by public opinion of the day, have had an equally potent effect whether they were historically well founded or ill founded. The stigma of being banned by the Great Charter was usually too great a burden for any institution or line of policy to bear. If the belief prevailed that an abuse complained of was really prohibited by Magna Carta, the most arbitrary king had difficulty in finding judges who would declare it legal, or trustworthy ministers who would persevere in enforcing it. The prevalence of such a belief was the main point; whether it was well or ill founded was, for political purposes, quite immaterial. The greatness of Magna Carta lies not so much in what it was to its framers in 1215, as in what it afterwards became to the political leaders, to the judges and lawyers, and to the entire mass of the men of England in later ages.
