Famous quotes containing the words special and/or cases:
“There is special providence in the fall of a sparrow. If it be now, ‘tis not to come; if it be not to come, it will be
now; if it be not now, yet it will come—the readiness is
all.”
—William Shakespeare (1564–1616)
“After all, the practical reason why, when the power is once in the hands of the people, a majority are permitted, and for a long period continue, to rule is not because they are most likely to be in the right, nor because this seems fairest to the minority, but because they are physically the strongest. But a government in which the majority rule in all cases cannot be based on justice, even as far as men understand it.”
—Henry David Thoreau (1817–1862)
