"Classical political economy nearly touches the true relation of things, without, however,consciously formulating it. This it cannot so long as it sticks in its bourgeois skin."

“[B]y quarrelling amongst themselves, instead of confederating, Germans and Scandinavians, both of them belonging to the same great race, only prepare the way for their hereditary enemy, the Slav.”

“The real point at issue always is Turkey in Europe – the great peninsula to the south of the Save and Danube. This splendid territory [the Balkans] has the misfortune to be inhabited by a conglomerate of different races and nationalities, of which it is hard to say which is the least fit for progress and civilization. Slavonians, Greeks, Wallachians, Arnauts, twelve millions of men, are all held in submission by one million of Turks, and up to a recent period, it appeared doubtful whether, of all these different races, the Turks were not the most competent to hold the supremacy which, in such a mixed population, could not but accrue to one of these nationalities.”

“Society is undergoing a silent revolution, which must be submitted to, and which takes no more notice of the human existences it breaks down than an earthquake regards the houses it subverts. The classes and the races, too weak to master the new conditions of life, must give way. But can there be anything more puerile, more short-sighted, than the views of those Economists who believe in all earnest that this woeful transitory state means nothing but adapting society to the acquisitive propensities of capitalists, both landlords and money-lords?”

“[I]t is our interest and our task to make the revolution permanent until all the more or less propertied classes have been driven from their ruling positions, until the proletariat has conquered state power and until the association of the proletarians has progressed sufficiently far – not only in one country but in all the leading countries of the world – that competition between the proletarians of these countries ceases and at least the decisive forces of production are concentrated in the hands of the workers. Our concern cannot simply be to modify private property, but to abolish it, not to hush up class antagonisms but to abolish classes, not to improve the existing society but to found a new one.”

“Did you not read our articles about the June revolution, and was not the essence of the June revolution the essence of our paper? Why then your hypocritical phrases, your attempt to find an impossible pretext? We have no compassion and we ask no compassion from you. When our turn comes, we shall not make excuses for the terror. But the royal terrorists, the terrorists by the grace of God and the law, are in practice brutal, disdainful, and mean, in theory cowardly, secretive, and deceitful, and in both respects disreputable.”

“[T]he very cannibalism of the counterrevolution will convince the nations that there is only one way in which the murderous death agonies of the old society and the bloody birth throes of the new society can be shortened, simplified and concentrated, and that way is revolutionary terror.”
