Famous quotes containing the words direct and/or image:
“One should never direct people towards happiness, because happiness too is an idol of the market-place. One should direct them towards mutual affection. A beast gnawing at its prey can be happy too, but only human beings can feel affection for each other, and this is the highest achievement they can aspire to.”
—Alexander Solzhenitsyn (b. 1918)
““Power may be at the end of a gun,” but sometimes it’s also at the end of the shadow or the image of a gun.”
—Jean Genet (1910–1986)
