Famous quotes containing the words the need and/or display:
“As between these two, the need that in its haste to be abolished cannot pause to be stated and the need that is the absolute predicament of particular human identity, one does not presume to suggest a relation of worth. Yet the distinction is perhaps not idle, for it is from the failure to make it that proceeds the common rejection as “obscure” of most that is significant in modern music, painting and literature.”
—Samuel Beckett (1906–1989)
“I mistrust the satisfaction which makes a display of the possession of Infinity; that is called fatuity in philosophic terms.”
—Edgar Quinet (1803–1875)
