Famous quotes containing the words air and/or core:
“The air is precious to the red man, for all things share the same breath—the beast, the tree, the man, they all share the same breath. The white man does not seem to notice the air he breathes. Like a man dying for many days, he is numb to the stench.”
—Attributed to Seattle (c. 1784–1866)
“In the core of God’s abysm,—
Was a weed of self and schism;
And ever the Daemonic Love
Is the ancestor of wars,
And the parent of remorse.”
—Ralph Waldo Emerson (1803–1882)
