Famous quotes containing the word symbol:
“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)
“Mysticism is the mistake of an accidental and individual symbol for an universal one.”
—Ralph Waldo Emerson (1803–1882)
“There is that in me—I do not know what it is—but I know it is in me ...
I do not know it—it is without name—it is a word unsaid,
It is not in any dictionary, utterance, symbol ...
Do you see O my brothers and sisters?
It is not chaos or death—it is form, union, plan—it is eternal life—it is Happiness.”
—Walt Whitman (1819–1892)
