Verification Performed

Famous quotes containing the words verification and/or performed:

“A fact is a proposition of which the verification by an appeal to the primary sources of our knowledge or to experience is direct and simple.

—Chauncey Wright (1830–1875)

“Poetry is the only life got, the only work done, the only pure product and free labor of man, performed only when he has put all the world under his feet, and conquered the last of his foes.”
—Henry David Thoreau (1817–1862)
