Famous quotes containing the words pneumatic and/or springs:
“Food probably has a very great influence on the condition of men. Wine exercises a more visible influence, food does it more slowly but perhaps just as surely. Who knows if a well-prepared soup was not responsible for the pneumatic pump or a poor one for a war?”
—G.C. (Georg Christoph)
“I hate Science. It denies a man’s responsibility for his own deeds, abolishes the brotherhood that springs from God’s fatherhood. It is a hectoring, dictating expertise, which makes the least lovable of the Church Fathers seem liberal by contrast. It is far easier for a Hitler or a Stalin to find a mock- scientific excuse for persecution than it was for Dominic to find a mock-Christian one.”
—Basil Bunting (1900–1985)
