Famous quotes containing the words deep and/or thought:
“How deep is our desire to do better than our mothers—to bring daughters into adulthood strong and fierce yet loving and gentle, adventurous and competitive but still nurturing and friendly, sweet yet sharp. We know as working women that we can’t quite have it all, but that hasn’t stopped us from wanting it all for them.”
—Anne Roiphe (20th century)
“Upon the whole, necessity is something, that exists in the mind, not in objects; nor is it possible for us ever to form the most distant idea of it, consider’d as a quality in bodies. Either we have no idea of necessity, or necessity is nothing but that determination of thought to pass from cause to effects and effects to causes, according to their experienc’d union.”
—David Hume (1711–1776)
