Majority Opinion: Debs. v. United States, Justice
Oliver Wendell Holmes 
This is an indictment under the Espionage Act of June 15, 1917. . . . The defendant was found guilty and was sentenced to ten years' imprisonment on each of the two counts, the punishment to run concurrently on both.
The main theme of the speech was Socialism, its growth, and a prophecy of its ultimate success. With that we have nothing to do, but if a part or the manifest intent of the more general utterances was to encourage those present to obstruct the recruiting service and if in passages such encouragement was directly given, the immunity of the general theme may not be enough to protect the speech. The speaker began by saying that he had just returned from a visit to the workhouse in the neighborhood where three of their most loyal comrades were paying the penalty for their devotion to the working class-these being Wagenknecht, Baker and Ruthenberg, who had been convicted of aiding and abetting another in failing to register for the draft. . . .
There followed personal experiences and illustrations of the growth of Socialism, a glorification of minorities, and a prophecy of the success of the international Socialist crusade, with the interjection that "you need to know that you are fit for something better than slavery and cannon fodder." The rest of the discourse had only the indirect thought not necessarily ineffective bearing on the offences alleged that is to be found in the usual contrasts between capitalists and laboring men, sneers at the advice to cultivate war gardens, attribution to plutocrats of the high price of coal, &c., with the implication running through it all that the working men are not concerned in the war, and a final exhortation, "Don't worry about the charge of treason to your masters; but be concerned about the treason that involves yourselves." The defendant addressed the jury himself, and while contending that his speech did not warrant the charges said, "I have been accused of obstructing the war. I admit it. Gentlemen, I abhor war. I would oppose the war if I stood alone." The statement was not necessary to warrant the jury in finding that one purpose of the speech, whether incidental or not does not matter, was to oppose not only war in general but this war, and that the opposition was so expressed that its natural and intended effect would be to obstruct recruiting. If that was intended and if, in all the circumstances, that would be its probable effect, it would not be protected by reason of its being part of a general program and expressions of a general and conscientious belief.
