Famous quotes containing the word power:
“A state that denies its citizens their basic rights becomes a danger to its neighbors as well: internal arbitrary rule will be reflected in arbitrary external relations. The suppression of public opinion, the abolition of public competition for power and its public exercise opens the way for the state power to arm itself in any way it sees fit.... A state that does not hesitate to lie to its own people will not hesitate to lie to other states.”
—Václav Havel (b. 1936)
“The truths of religion are never so well understood as by those who have lost the power of reason.”
—Voltaire [François Marie Arouet] (1694–1778)
“People ask me: “Why do you write about food, and eating, and drinking? Why don’t you write about the struggle for power and security, and about love, the way the others do?”... The easiest answer is to say that, like most other humans, I am hungry.”
—M.F.K. Fisher (1908–1992)
