Boundary

Famous quotes containing the word boundary:

“No man has a right to fix the boundary of the march of a nation; no man has a right to say to his country, “Thus far shalt thou go and no further.””
—Charles Stewart Parnell (1846–1891)

“Superstition? Who can define the boundary line between the superstition of yesterday and the scientific fact of tomorrow?”
—Garrett Fort (1900–1945)

“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)
