Famous quotes containing the words tools and, 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)
“The study of tools as well as of books should have a place in the public schools. Tools, machinery, and the implements of the farm should be made familiar to every boy, and suitable industrial education should be furnished for every girl.”
—Rutherford Birchard Hayes (1822–1893)
“Soon silence will have passed into legend. Man has turned his back on silence. Day after day he invents machines and devices that increase noise and distract humanity from the essence of life, contemplation, meditation.... Tooting, howling, screeching, booming, crashing, whistling, grinding, and trilling bolster his ego. His anxiety subsides. His inhuman void spreads monstrously like a gray vegetation.”
—Jean Arp (1887–1948)
