Famous quotes containing the words left and/or boundary:
“Woman was originally the inventor, the manufacturer, the provider. She has allowed one office after another gradually to slip from her hand, until she retains, with loose grasp, only the so-called housekeeping.... Having thus given up one by one the occupations which required knowledge of materials and processes, and skill in using them ... she rightly feels that what’s left is mere deadening drudgery.”
—Ellen Henrietta Swallow Richards (1842–1911)
“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)
