Famous quotes containing the words power and/or ring:
“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)
“Ring out the old, ring in the new,
Ring happy bells, across the snow:
The year is going, let him go;
Ring out the false, ring in the true.”
—Alfred Tennyson (1809–1892)
