Boundary/psychology

Famous quotes containing the words boundary and/or psychology:

“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)

“Idleness is the beginning of all psychology. What? Could it be that psychology is—a vice?”
—Friedrich Nietzsche (1844–1900)
