"The Mutabilities of Literature".
The Sketch Book of Geoffrey Crayon (1819–1820)
Context: There rise authors now and then, who seem proof against the mutability of language, because they have rooted themselves in the unchanging principles of human nature. They are like gigantic trees that we sometimes see on the banks of a stream; which, by their vast and deep roots, penetrating through the mere surface, and laying hold on the very foundations of the earth, preserve the soil around them from being swept away by the ever-flowing current, and hold up many a neighboring plant, and perhaps worthless weed, to perpetuity.

Against the Galilaeans (c. 362)
Context: Men's works also are naturally perishable and mutable and subject to every kind of alteration. But since God is eternal, it follows that of such sort are his ordinances also.

How could it fall out of harmony therewith?

Who can say where the cloud's blowed from or who the soul'll be 'morrow? Only Sonmi the east an' the compass an' the atlas, yay, only the atlas o' clouds.
