Famous quotes containing the word technology:
“Technology is not an image of the world but a way of operating on reality. The nihilism of technology lies not only in the fact that it is the most perfect expression of the will to power ... but also in the fact that it lacks meaning.”
—Octavio Paz (b. 1914)
“The successor to politics will be propaganda. Propaganda, not in the sense of a message or ideology, but as the impact of the whole technology of the times.”
—Marshall McLuhan (1911–1980)
“Primitive peoples tried to annul death by portraying the human body—we do it by finding substitutes for the human body. Technology instead of mysticism!”
—Max Frisch (1911–1991)
