“Nonviolence is a powerful and just weapon. Indeed, it is a weapon unique in history, which cuts without wounding and ennobles the man who wields it.”

Context: One free man will say with truth what he thinks and feels amongst thousands of men who by their acts and words attest exactly the opposite. It would seem that he who sincerely expressed his thought must remain alone, whereas it generally happens that every one else, or the majority at least, have been thinking and feeling the same things but without expressing them.
And that which yesterday was the novel opinion of one man, to-day becomes the general opinion of the majority.
And as soon as this opinion is established, immediately by imperceptible degrees, but beyond power of frustration, the conduct of mankind begins to alter.
Whereas at present, every man, even, if free, asks himself, "What can I do alone against all this ocean of evil and deceit which overwhelms us? Why should I express my opinion? Why indeed possess one? It is better not to reflect on these misty and involved questions. Perhaps these contradictions are an inevitable condition of our existence. And why should I struggle alone with all the evil in the world? Is it not better to go with the stream which carries me along? If anything can be done, it must be done not alone but in company with others."
And leaving the most powerful of weapons — thought and its expression — which move the world, each man employs the weapon of social activity, not noticing that every social activity is based on the very foundations against which he is bound to fight, and that upon entering the social activity which exists in our world every man is obliged, if only in part, to deviate from the truth and to make concessions which destroy the force of the powerful weapon which should assist him in the struggle. It is as if a man, who was given a blade so marvelously keen that it would sever anything, should use its edge for driving in nails.
We all complain of the senseless order of life, which is at variance with our being, and yet we refuse to use the unique and powerful weapon within our hands — the consciousness of truth and its expression; but on the contrary, under the pretext of struggling with evil, we destroy the weapon, and sacrifice it to the exigencies of an imaginary conflict'.

Context: America and Russia have excessive numbers of nuclear weapons today because we treated nuclear weapons, at the end of World War II, like they were just bigger conventional weapons. If you have tanks, and the other side has more than you, you may be in trouble — or airplanes or ships or whatever. With nuclear weapons, it's not the same: they're too powerful, and at some point you just can't use any more, it's just not meaningful. But what happened was, we had the lead of course, because we invented them. The Russians tried to catch up with us; we tried to stay ahead of the Russians; they tried to catch up with us, and we just had a never-ending race upward. By the mid-Sixties, we realized this, but because of the Cold War mentality, politicians couldn't stand up and say, "I'm willing to have less than the Soviet Union," and so the race continued, but we tried to mitigate it by instituting an arms control process, which at first tried to cap and then later to reduce these numbers. … there's just no way you can actually use them; they become so destructive. I estimate that a couple of hundred nuclear weapons, not just on the center of cities, but on economic positions in the country, will drive a country to the point it will never recover, it will never be the same again. It will survive, but it'll be a totally different country. You don't need thousands to do that. There are only a few hundred cities of any size in even Russia or the United States, like 200, and you just don't need thousands of weapons to demobilize a country.
