Water Boundary

Famous quotes containing the words water and/or boundary:

“We have to learn how to come out of unclean situations cleaner than we were, and even how to wash ourselves with dirty water when we need to.”
—Friedrich Nietzsche (1844–1900)

“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
