like the diamond

The art which only gilds the surface and demands merely a superficial polish, without reaching to the core, is but varnish and filigree. But the work of genius is rough-hewn from the first, because it anticipates the lapse of time and has an ingrained polish, which still appears when fragments are broken off, an essential quality of its substance. Its beauty is its strength. It breaks with a lustre, and splits in cubes and diamonds. Like the diamond, it has only to be cut to be polished, and its surface is a window to its interior splendors.
