Famous quotes containing the word power:

    See, I have given you authority to tread on snakes and scorpions, and over all the power of the enemy; and nothing will hurt you. Nevertheless, do not rejoice at this, that the spirits submit to you, but rejoice that your names are written in heaven.
    Bible: New Testament, Luke 10:19,20.

    True freedom is to have power over oneself for everything.
    Michel de Montaigne (1533–1592)

    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)
