Boundary Wall

Famous quotes containing the words boundary and/or wall:

“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)

“Last night you wrote on the wall: Revolution is poetry.
Today you needn’t write; the wall has tumbled down.”
—Adrienne Rich (b. 1929)
