Famous quotes containing the word symbol:
“A symbol is indeed the only possible expression of some invisible essence, a transparent lamp about a spiritual flame; while allegory is one of many possible representations of an embodied thing, or familiar principle, and belongs to fancy and not to imagination: the one is a revelation, the other an amusement.”
—William Butler Yeats (1865–1939)
“The truth has never been of any real value to any human being—it is a symbol for mathematicians and philosophers to pursue. In human relations kindness and lies are worth a thousand truths.”
—Graham Greene (1904–1991)
“Every natural fact is a symbol of some spiritual fact. Every appearance in nature corresponds to some state of the mind, and that state of the mind can only be described by presenting that natural appearance as its picture.”
—Ralph Waldo Emerson (1803–1882)
