III. Nor is this all; but we may observe, that exactly in proportion to the majesty of things in the scale of being, is the completeness of their obedience to the laws that are set over them. Gravitation is less quietly, less instantly obeyed by a grain of dust than it is by the sun and moon; and the ocean falls and flows under influences which the lake and river do not recognize. So also in estimating the dignity of any action or occupation of men, there is perhaps no better test than the question "are its laws strait?" For their severity will probably be commensurate with the greatness of the numbers whose labor it concentrates or whose interest it concerns. This severity must be singular, therefore, in the case of that art, above all others, whose productions are the most vast and the most common; which requires for its practice the co-operation of bodies of men, and for its perfection the perseverance of successive generations. And taking into account also what we have before so often observed of Architecture, her continual influence over the emotions of daily life, and her realism, as opposed to the two sister arts which are in comparison but the picturing of stories and of dreams, we might beforehand expect that we should find her healthy state and action dependent on far more severe laws than theirs; that the license which they extend to the workings of individual mind would be withdrawn by her; and that, in assertion of the relations which she holds with all that is universally important to man, she would set forth, by her own majestic subjection, some likeness of that on which man's social happiness and power depend. We might, therefore, without the light of experience, conclude, that Architecture never could flourish except when it was subjected to a national law as strict and as minutely authoritative as the laws which regulate religion, policy, and social relations; nay, even more authoritative than these, because both capable of more enforcement, as over more passive matter; and needing more enforcement, as the purest type not of one law nor of another, but of the common authority of all. But in this matter experience speaks more loudly than reason. If there be any one condition which, in watching the progress of architecture, we see distinct and general; if, amidst the counter evidence of success attending opposite accidents of character and circumstance, any one conclusion may be constantly and indisputably drawn, it is this; that the architecture of a nation is great only when it is as universal and as established as its language; and when provincial differences of style are nothing more than so many dialects. Other necessities are matters of doubt: nations have been alike successful in their architecture in times of poverty and of wealth; in times of war and of peace; in times of barbarism and of refinement; under governments the most liberal or the most arbitrary; but this one
