First, the King could not legislate without the consent of his Parliament. Secondly, he could impose no tax without the consent of his Parliament. Thirdly, he was bound to conduct the executive administration according to the laws of the land, and, if he broke those laws, his advisers and his agents were responsible. No candid Tory will deny that these principles had, five hundred years ago, acquired the authority of fundamental rules. On the other hand, no candid Whig will affirm that they were, till a later period, cleared from all ambiguity, or followed out to all their consequences. A constitution of the middle ages was not, like a constitution of the eighteenth or nineteenth century, created entire by a single act, and fully set forth in a single document. It is only in a refined and speculative age that a polity is constructed on system. In rude societies the progress of government resembles the progress of language and of versification. Rude societies have language, and often copious and energetic language: but they have no scientific grammar, no definitions of nouns and verbs, no names for declensions, moods, tenses, and voices. Rude societies have versification, and often versification of great power and sweetness: but they have no metrical canons; and the minstrel whose numbers, regulated solely by his ear, are the delight of his audience, would himself be unable to say of how many dactyls and trochees each of his lines consists. As eloquence exists before syntax, and song before prosody, so government may exist in a high degree of excellence long before the limits of legislative, executive, and judicial power have been traced with precision. It was thus in our country. The line which bounded the royal prerogative, though in general sufficiently clear, had not everywhere been drawn with accuracy and distinctness. There was, therefore, near the border some debatable ground on which incursions and reprisals continued to take place, till, after ages of strife, plain and durable landmarks were at length set up. It may be instructive to note in what way, and to what extent, our ancient sovereigns were in the habit of violating the three great principles by which the liberties of the nation were protected.
