But force is to be used only as a "last resort."[825] "When a physician sees that his patient's strength is being exhausted so rapidly by the intensity of his agony that he will die of exhaustion before the medical processes inaugurated have a chance to do their curative work, he administers an opiate. But a good physician is always loth to do so, knowing that one of the influences of the opiate is to interfere with and defeat the medical processes themselves. It is the same with the use of force, whether of the mob or of the State, upon diseased society; and not only those who prescribe its indiscriminate use as a sovereign remedy and a permanent tonic, but all who ever propose it as a cure, and even all who would lightly and unnecessarily resort to it, not as a cure, but as an expedient, _are social quacks_."[826] Therefore violence "should be used against the oppressors of mankind only when they have succeeded in hopelessly repressing all peaceful methods of agitation."[827] "Bloodshed in itself is pure loss. When we must have freedom of agitation, and when nothing but bloodshed will secure it, then bloodshed is wise."[828] "As long as freedom of speech and of the press is not struck down, there should be no resort to physical force in the struggle against oppression. It must not be inferred that, because 'Libertas' thinks it may become advisable to use force to secure free speech, it would therefore sanction a bloody deluge as soon as free speech had been struck down in one, a dozen, or a hundred instances. Not until the gag had become completely efficacious would 'Libertas' advise that last resort, the use of force."[829] "Terrorism is expedient in Russia and inexpedient in Germany and England."[830]--In what form is violence to be used? "The days of armed revolution have gone by. It is too easily put down."[831] "Terrorism and assassination"[832] are necessary, but they "will have to consist of a series of acts of individual dynamiters."[833] 3. But, besides speech and the press, there are yet other methods of "propagandism."[834]
