Famous quotes containing the words protected and/or mode:
“If one really wishes to know how justice is administered in a country, one does not question the policemen, the lawyers, the judges, or the protected members of the middle class. One goes to the unprotected—those, precisely, who need the laws’s protection most!—and listens to their testimony.”
—James Baldwin (1924–1987)
“There are a thousand hacking at the branches of evil to one who is striking at the root, and it may be that he who bestows the largest amount of time and money on the needy is doing the most by his mode of life to produce that misery which he strives in vain to relieve.”
—Henry David Thoreau (1817–1862)
