Dialectical thinking is related to vulgar thinking in the same way that a motion picture is related to a still photograph. The motion picture does not outlaw the still photograph but combines a series of them according to the laws of motion. Dialectics does not deny the syllogism, but teaches us to combine syllogisms in such a way as to bring our understanding closer to the eternally changing reality.

The bourgeoisie today is a falling class. ... By its imperialist methods of appropriation [it] is destroying the economic structure of the world and human culture generally. Nevertheless, the historical persistence of the bourgeoisie is colossal. It holds to power, and does not wish to abandon it. Thereby it threatens to drag after it into the abyss the whole of society. We are forced to tear it off, to chop it away. The Red Terror is a weapon utilized against a class, doomed to destruction, which does not wish to perish. If the White Terror can only retard the historical rise of the proletariat, the Red Terror hastens the destruction of the bourgeoisie.

The people, in the shape of the most democratic elements, were in favor of extreme measures. The Republican Party had a decided majority in the North, and persons suspected of secessionism, i.e., of sympathizing with the rebellious Southern states, were subjected to violence. In some northern towns, and even in the states of New England, famous for their order, the people frequently burst into the offices of newspapers which supported the revolting slave-owners and smashed their printing presses. It occasionally happened that reactionary publishers were smeared with tar, decorated with feathers, and carried in such array through the public squares until they swore an oath of loyalty to the Union. The personality of a planter smeared in tar bore little resemblance to the “end-in-itself ;” so that the categorical imperative of Kautsky suffered in the civil war of the states a considerable blow.
