Famous quotes containing the words codes and/or today:
“We must trust infinitely to the beneficent necessity which shines through all laws. Human nature expresses itself in them as characteristically as in statues, or songs, or railroads, and an abstract of the codes of nations would be an abstract of the common conscience.”
—Ralph Waldo Emerson (1803–1882)
“We had to take the world as it was given:
The nursemaid sitting passive in the park
Was rarely by a changeling prince accosted,
The mornings happened similar and stark
In rooms of selfhood where we woke and lay
Watching today unfold like yesterday.”
—Adrienne Rich (b. 1929)
