Famous quotes containing the words vision and/or loss:
“One will meet, for example, the virtual assumption that what is relative to thought cannot be real. But why not, exactly? Red is relative to sight, but the fact that this or that is in that relation to vision that we call being red is not itself relative to sight; it is a real fact.”
—Charles Sanders Peirce (1839–1914)
“Nothing that grieves us can be called little: by the eternal laws of proportion a child’s loss of a doll and a king’s loss of a crown are events of the same size.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
