“This could be the beginning of Civil War. There is no kind more distressing, no kind which so rapidly describes the pointlessness of human killing human. I have been fated, for a reason I cannot comprehend or for no reason at all, to witness the worst examples of insane warfare (and all warfare, it seems to me now, is that) and having to listen to the most ridiculous explanations as to its “necessity” from otherwise perfectly rational people, I have long since become weary, Moorcock, of the debate. If I appear to you to be in a more reconciled mood than when your grandfather first met me it is because I have learned that no individual is responsible for War—that we are all, at the same time, individually responsible for the ills of the human condition. In learning this, (and I am about to tell you how I learned it) I also learned a certain tolerance for myself and for others which I had never previously possessed.”

Highway of Eternity (1986)
Context: Perversity, she thought. Could that have been what happened to the human race — a willing perversity that set at naught all human values which had been so hardly won and structured in the light of reason for a span of more than a million years? Could the human race, quite out of hand and with no sufficient reason, have turned its back upon everything that had built humanity? Or was it, perhaps, no more than second childhood, a shifting of the burden off one's shoulders and going back to the selfishness of the child who romped and frolicked without thought of consequence or liability?

Address on sentencing (1885)
Context: The Court. has done the work for me, and although at first appearance it seems to be against me, I am so confident in the idea which I have had the honor to express yesterday, that I think it is for good and not for my loss. Up to this moment, I have been considered by a certain party as insane, by another party as a criminal, by another party as a man with whom it was doubtful whether to have any intercourse. So there was hostility and there was contempt, and there was avoidance To-day, by the verdict of the Court, one of these three situations has disappeared.
I suppose that after having been condemned, I will cease to be called a fool, and for me it is a great advantage. I consider it as a great advantage. If I have a mission, I say "If " for the sake of those who doubt, but for my part it means "Since," since I have a mission, I cannot fulfil my mission as long as I am looked upon as an insane being-human being, at the moment that I begin to ascend that scale, I begin to succeed.

It won't even be an interesting debate, getting killed by shrapnel, in my opinion is a lot more gruesome and a lot worse.

Commencement address at Lindsey Wilson College (14 May 2005) http://www.lindsey.edu/index.cgi?id=10379.
Context: The line that connects the bombing of civilian populations to the mountain removed by strip mining … to the tortured prisoner seems to run pretty straight. We're living, it seems, in the culmination of a long warfare — warfare against human beings, other creatures and the Earth itself.
