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)
“For it is the suffering flesh, it is suffering, it is death, that lovers perpetuate upon the earth. Love is at once the brother, son, and father of death, which is its sister, mother, and daughter. And thus it is that in the depth of love there is a depth of eternal despair, out of which springs hope and consolation.”
—Miguel de Unamuno (1864–1936)
