Famous quotes containing the words major, concrete and/or structures:
“You should hurry up ... and acquire the cigar habit. It’s one of the major happinesses. And so much more lasting than love, so much less costly in emotional wear and tear.”
—Aldous Huxley (1894–1963)
“The clock of communism has stopped striking. But its concrete building has not yet come crashing down. For that reason, instead of freeing ourselves, we must try to save ourselves from being crushed by its rubble.”
—Alexander Solzhenitsyn (b. 1918)
“The philosopher believes that the value of his philosophy lies in its totality, in its structure: posterity discovers it in the stones with which he built and with which other structures are subsequently built that are frequently better—and so, in the fact that that structure can be demolished and yet still possess value as material.”
—Friedrich Nietzsche (1844–1900)
