But, if there are any of my hearers who have been impressed with this sense of inventive duty, may I ask them first, whether their plan is that every inventive architect among us shall invent a new style for himself, and have a county set aside for his conceptions, or a province for his practice? Or, must every architect invent a little piece of the new style, and all put it together at last like a dissected map? And if so, when the new style is invented, what is to be done next? I will grant you this Eldorado of imagination--but can you have more than one Columbus? Or, if you sail in company, and divide the prize of your discovery and the honour thereof, who is to come after you clustered Columbuses? to what fortunate islands of style are your architectural descendants to sail, avaricious of new lands? When our desired style is invented, will not the best we can all do be simply--to build in it?-- and cannot you now do that in styles that are known? Observe, I grant, for the sake of your argument, what perhaps many of you know that I would not grant otherwise--that a new style _can_ be invented. I grant you not only this, but that it shall be wholly different from any that was ever practised before. We will suppose that capitals are to be at the bottom of pillars instead of the top; and that buttresses shall be on the tops of pinnacles instead of at the bottom; that you roof your apertures with stones which shall neither be arched nor horizontal; and that you compose your decoration of lines which shall neither be crooked nor straight. The furnace and the forge shall be at your service: you shall draw out your plates of glass and beat out your bars of iron till you have encompassed us all,--if your style is of the practical kind,--with endless perspective of black skeleton and blinding square,--or if your style is to be of the ideal kind--you shall wreathe your streets with ductile leafage, and roof them with variegated crystal--you shall put, if you will, all London under one blazing dome of many colours that shall light the clouds round it with its flashing, as far as to the sea. And still, I ask you, What after this? Do you suppose those imaginations of yours will ever lie down there asleep beneath the shade of your iron leafage, or within the coloured light of your enchanted dome? Not so. Those souls, and fancies, and ambitions of yours, are wholly infinite; and, whatever may be done by others, you will still want to do something for yourselves; if you cannot rest content with Palladio, neither will you with Paxton: all the metal and glass that ever were melted have not so much weight in them as will clog the wings of one human spirit's aspiration.
