Famous quotes containing the words science and/or technology:

    “Science is built up with facts, as a house is with stones. But a collection of facts is no more a science than a heap of stones is a house.”
    —Jules Henri Poincare (1854–1912)

    “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)
