Famous quotes containing the words power and/or supply:
“The dissident does not operate in the realm of genuine power at all. He is not seeking power. He has no desire for office and does not gather votes. He does not attempt to charm the public, he offers nothing and promises nothing. He can offer, if anything, only his own skinand he offers it solely because he has no other way of affirming the truth he stands for. His actions simply articulate his dignity as a citizen, regardless of the cost.”
—Václav Havel (b. 1936)
“Has Gods supply of tolerable husbands
Fallen, in fact, so low?
Or do I always over-value woman
At the expense of man?
Do I?
It might be so.”
—Robert Graves (18951985)
