"I have not a bit of use for the "propaganda of the deed." These are the tactics of anarchist individualists and not of socialist collectivists. They were developed by and belong exclusively to our anarchist friends and accord perfectly with their philosophy. These and similar measures are reactionary, not revolutionary, and they invariably have a demoralizaing effect upon the following of those who practice them. If I believed in the doctrine of violence and destruction as part policy; if I regarded the class struggle as guerilla warfare, I would join the anarchists and practice as well as preach such tactics."

“There is no inspiration in evil and no power except for its own destruction.”

“In due time the hour will strike and this great cause triumphant — the greatest in history — will proclaim the emancipation of the working class and the brotherhood of all mankind.”

“If Theodore Roosevelt is the great champion of democracy —the arch foe of autocracy , what business had he as the guest of honor of the Prussian Kaiser? And when he met the Kaiser, and did honor to the Kaiser, under the terms imputed to him, wasn’t it pretty strong proof that he himself was a Kaiser at heart? Now, after being the guest of Emperor Wilhelm, the Beast of Berlin, he comes back to this country, and wants you to send ten million men over there to kill the Kaiser; to murder his former friend and pal. Rather queer, isn’t it? And yet, he is the patriot, and we are the traitors. I challenge you to find a Socialist anywhere on the face of the earth who was ever the guest of the Beast of Berlin, except as an inmate of his prison—the elder Liebknecht and the younger Liebknecht, the heroic son of his immortal sire.”

“The economic unity of the workers must first be effected before there can be any progress towards emancipation. The interests of the millions of wage workers are identical, regardless of nationality, creed, or sex, and if they will only open their eyes to this simple, self-evident fact, the greatest obstacle will have been overcome and the day of victory draw near.”

“There is but one thing you have to be concerned about, and that is that you keep foursquare with the principles of the international Socialist movement. It is only when you begin to compromise that trouble begins. So far as I am concerned, it does not matter what others may say, or think, or do, as long as I am sure that I am right with myself and the cause. There are so many who seek refuge in the popular side of a great question. As a Socialist, I have long since learned how to stand alone.”
