Famous quotes containing the words water and/or balance:
“Aesop, that great man, saw his master making water as he walked. “What!” he said, “Must we void ourselves as we run?” Use our time as best we may, yet a great part of it will still be idly and ill spent.”
—Michel de Montaigne (1533–1592)
“Both the man of science and the man of art live always at the edge of mystery, surrounded by it. Both, as a measure of their creation, have always had to do with the harmonization of what is new with what is familiar, with the balance between novelty and synthesis, with the struggle to make partial order in total chaos.... This cannot be an easy life.”
—J. Robert Oppenheimer (1904–1967)
