Famous quotes containing the words tools and/or devices:

    At the utmost, the active-minded young man should ask of his teacher only mastery of his tools. The young man himself, the subject of education, is a certain form of energy; the object to be gained is economy of his force; the training is partly the clearing away of obstacles, partly the direct application of effort. Once acquired, the tools and models may be thrown away.
    Henry Brooks Adams (1838–1918)

    There is nothing in machinery, there is nothing in embankments and railways and iron bridges and engineering devices to oblige them to be ugly. Ugliness is the measure of imperfection.
    —H.G. (Herbert George)
