Reference Direction

Famous quotes containing the words reference and/or direction:

“If we define a sign as an exact reference, it must include symbol because a symbol is an exact reference too. The difference seems to be that a sign is an exact reference to something definite and a symbol an exact reference to something indefinite.”
—William York Tindall (1903–1981)

“Virtuous people are simply those who have ... not been tempted sufficiently, because they live in a vegetative state, or because their purposes are so concentrated in one direction that they have not had the leisure to glance around them.”
—Isadora Duncan (1878–1927)
