“Why does the guerrilla fighter fight? We must come to the inevitable conclusion that the guerrilla fighter is a social reformer, that he takes up arms responding to the angry protest of the people against their oppressors, and that he fights in order to change the social system that keeps all his unarmed brothers in ignominy and misery.”

Jean-Christophe (1904 - 1912), Journey's End: The Burning Bush (1911)
Context: "Thou art not alone, and thou dost not belong to thyself. Thou art one of My voices, thou art one of My arms. Speak and strike for Me. But if the arm be broken, or the voice be weary, then still I hold My ground: I fight with other voices, other arms than thine. Though thou art conquered, yet art thou of the army which is never vanquished. Remember that and thou wilt fight even unto death."
"Lord, I have suffered much!"
"Thinkest thou that I do not suffer also? For ages death has hunted Me and nothingness has lain in wait for Me. It is only by victory in the fight that I can make My way. The river of life is red with My blood."
"Fighting, always fighting?"
"We must always fight. God is a fighter, even He Himself. God is a conqueror. He is a devouring lion. Nothingness hems Him in and He hurls it down. And the rhythm of the fight is the supreme harmony. Such harmony is not for thy mortal ears. It is enough for thee to know that it exists. Do thy duty in peace and leave the rest to the Gods."

Doin' It Again, Parental Advisory: Explicit Lyrics (1990)
Context: Smug, greedy, well-fed white people have invented a language to conceal their sins. It's as simple as that. The CIA doesn't kill anybody anymore, they neutralize people, or they depopulate the area. The government doesn't lie, it engages in disinformation. The Pentagon actually measures nuclear radiation in something they call sunshine units. Israeli murderers are called commandos, Arab commandos are called terrorists. Contra killers are called freedom fighters. Well, if crime fighters fight crime, and firefighters fight fires, what do freedom fighters fight?

Excerpt from a late March 1942 memorandum King wrote to President Roosevelt, urging against adopting the policy of those most concerned with defending the continental United States. It is unknown if the memorandum was actually ever seen by the President. The entire memorandum is quoted by Thomas B. Buell in his book Master of Sea Power: A Biography of Fleet Admiral Ernest J. King (1980), p. 193.

As quoted in The Many Faces of Socialism Comparative Sociology and Politics (1983) by Paul Hollander, p. 224,
Context: I am not interested in dry economic socialism. We are fighting against misery, but we are also fighting against alienation. One of the fundamental objectives of Marxism is to remove interest, the factor of individual interest, and gain, from people's psychological motivations. Marx was preoccupied both with economic factors and with their repercussions on the spirit. If communism isn't interested in this too, it may be a method of distributing goods, but it will never be a revolutionary way of life.
