“Communism is the riddle of history solved, and it knows itself to be this solution.”

“Communism is for us not a state of affairs which is to be established, an ideal to which reality [will] have to adjust itself. We call communism the real movement which abolishes the present state of things. The conditions of this movement result from the premises now in existence.”

“A specter is haunting Europe—the specter of Communism. All the powers of old Europe have entered into a holy alliance to exorcise this specter; Pope and Czar, Metternich and Guizot, French radicals and German police spies.Where is the party in opposition that has not been decried as Communistic by its opponents in power? Where the opposition that has not hurled back the branding reproach of Communism, against the more advanced opposition parties, as well as against its reactionary adversaries?Two things result from this fact.I. Communism is already acknowledged by all European powers to be in itself a power.II. It is high time that Communists should openly, in the face of the whole world, publish their views, their aims, their tendencies, and meet this nursery tale of the Specter of Communism with a Manifesto of the party itself.”

“All mysteries which lead theory to mysticism find their rational solution in human practice and in the comprehension of this practice.”

“...[G]reat progress was evident in the last Congress of the American 'Labour Union' in that among other things, it treated working women with complete equality. While in this respect the English, and still more the gallant French, are burdened with a spirit of narrow-mindedness. Anybody who knows anything of history knows that great social changes are impossible without the feminine ferment. Social progress can be measured exactly by the social position of the fair sex (the ugly ones included).”

“Communism deprives no man of the power to appropriate the products of society: all that it does is to deprive him of the power to subjugate the labor of others by means of such appropriation.It has been objected, that upon the abolition of private property all work will cease, and universal laziness will overtake us.According to this, bourgeois society ought long ago to have gone to the dogs through sheer idleness; for those of its members who work, acquire nothing, and those who acquire anything, do not work.”

“The theoretical conclusions of the Communists are in no way based on ideas or principles that have been invented, or discovered, by this or that would -be universal reformer. They merely express, in general terms, actual relations springing from an existing class struggle, from a historical movement going on under our very eyes. The abolition of existing property relations is not at all a distinctive feature of communism. All property relations in the past have continually been subject to historical change consequent upon the change in historical conditions.”
