Famous quotes containing the words direct and/or secondary:
“Besides, our action on each other, good as well as evil, is so incidental and at random, that we can seldom hear the acknowledgments of any person who would thank us for a benefit, without some shame and humiliation. We can rarely strike a direct stroke, but must be content with an oblique one; we seldom have the satisfaction of yielding a direct benefit, which is directly received.”
—Ralph Waldo Emerson (1803–1882)
“Cloud-clown, blue painter, sun as horn,
Hill-scholar, man that never is,
The bad-bespoken lacker,
Ancestor of Narcissus, prince
Of the secondary men. There are no rocks
And stones, only this imager.”
—Wallace Stevens (1879–1955)
