Famous quotes containing the word power:
“I call the discourse of power any discourse that engenders blame, hence guilt, in its recipient.”
—Roland Barthes (1915–1980)
“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)
“The quality of the will to power is, precisely, growth. Achievement is its cancellation. To be, the will to power must increase with each fulfillment, making the fulfillment only a step to a further one. The vaster the power gained the vaster the appetite for more.”
—Ursula K. Le Guin (b. 1929)
