V. The violations of truth, which dishonor poetry and painting, are thus for the most part confined to the treatment of their subjects. But in architecture another and a less subtle, more contemptible, violation of truth is possible; a direct falsity of assertion respecting the nature of material, or the quantity of labor. And this is, in the full sense of the word, wrong; it is as truly deserving of reprobation as any other moral delinquency; it is unworthy alike of architects and of nations; and it has been a sign, wherever it has widely and with toleration existed, of a singular debasement of the arts; that it is not a sign of worse than this, of a general want of severe probity, can be accounted for only by our knowledge of the strange separation which has for some centuries existed between the arts and all other subjects of human intellect, as matters of conscience. This withdrawal of conscientiousness from among the faculties concerned with art, while it has destroyed the arts themselves, has also rendered in a measure nugatory the evidence which otherwise they might have presented respecting the character of the respective nations among whom they have been cultivated; otherwise, it might appear more than strange that a nation so distinguished for its general uprightness and faith as the English, should admit in their architecture more of pretence, concealment, and deceit, than any other of this or of past time. They are admitted in thoughtlessness, but with fatal effect upon the art in which they are practised. If there were no other causes for the failures which of late have marked every great occasion for architectural exertion, these petty dishonesties would be enough to account for all. It is the first step and not the least, towards greatness to do away with these; the first, because so evidently and easily in our power. We may not be able to command good, or beautiful, or inventive architecture; but we _can_ command an honest architecture: the meagreness of poverty may be pardoned, the sternness of utility respected; but what is there but scorn for the meanness of deception? VI. Architectural Deceits are broadly to be considered under three heads:-- 1st. The suggestion of a mode of structure or support, other than the true one; as in pendants of late Gothic roofs. 2d. The painting of surfaces to represent some other material than that of which they actually consist (as in the marbling of wood), or the deceptive representation of sculptured ornament upon them. 3d. The use of cast or machine-made ornaments of any kind.
