In writing, you discover interior sonorities in words. Dipthongs sound differently beneath the pen. One hears them with their sounds divorced.

What action could bodies and substances have if they were not named in a further increase of dignity where common nouns become proper nouns?

Ideas are refined and multiplied in the commerce of minds. In their splendor, images effect a very simple communion of souls.

In scientific thought, the concept functions all the better for being cut off from all background images.
