Famous quotes containing the words shelf and/or boundary:
“Books are like imprisoned souls till someone takes them down from a shelf and frees them.”
—Samuel Butler (1835–1902)
“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)
