“You must remember what you are and what you have chosen to become, and the significance of what you are doing. There are wars and defeats and victories of the human race that are not military and that are not recorded in the annals of history. Remember that while you're trying to decide what to do.”
― John Williams, Stoner

“Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for.”
― Epicurus

“Nationalism is our form of incest, is our idolatry, is our insanity. 'Patriotism' is its cult...Just as love for one individual which excludes the love for others is not love, love for one's country which is not part of one's love for humanity is not love, but idolatrous worship.”
― Erich Fromm

“... a mind needs books as a sword needs a whetstone, if it is to keep its edge.”
― George R.R. Martin, A Game of Thrones
