4 the arts, I have endeavoured to trace in the following pages; and since, if truly stated, they must necessarily be, not only safeguards against every form of error, but sources of every measure of success, I do not think that I claim too much for them in calling them the Lamps of Architecture, nor that it is indolence, in endeavouring to ascertain the true nature and nobility of their fire, to refuse to enter into any curious or special questioning of the innumerable hindrances by which their light has been too often distorted or overpowered. Had this farther examination been attempted, the work would have become certainly more invidious, and perhaps less useful, as liable to errors which are avoided by the present simplicity of its plan. Simple though it be, its extent is too great to admit of any adequate accomplishment, unless by a devotion of time which the writer did not feel justified in withdrawing from branches of inquiry in which the prosecution of works already undertaken has engaged him. Both arrangement and nomenclature are those of convenience rather than of system; the one is arbitrary and the other illogical: nor is it pretended that all, or even the greater number of, the principles necessary to the well-being of the art, are included in the inquiry. Many, however, of considerable importance will be found to develop themselves incidentally from those more specially brought forward. Graver apology is necessary for an apparently graver fault. It has been just said, that there is no branch of human work whose constant laws have not close analogy with those which govern every other mode of man's exertion. But, more than this, exactly as we reduce to greater simplicity and surety any one group of these practical laws, we shall find them passing the mere condition of connection or analogy, and becoming the actual expression of some ultimate nerve or fibre of the mighty laws which govern the moral world.
