"The proletarian works with the instruments of production of another, for the account of this other, in exchange for a part of the product. ... The proletarian liberates himself by abolishing competition, private property, and all class differences."

“The irony of world history turns everything upside down. We, the "revolutionaries," the "rebels"—we are thriving far better on legal methods than on illegal methods and revolt. The parties of order, as they call themselves, are perishing under the legal conditions created by themselves. They cry despairingly with Odilon Barrot: la légalité notes tue, legality is the death of us; whereas we, under this legality, get firm muscles and rosy cheeks and look like eternal life.”

“The proletariat is that class in society which lives entirely from the sale of its labor and does not draw profit from any kind of capital; whose weal and woe, whose life and death, whose sole existence depends on the demand for labor – hence, on the changing state of business, on the vagaries of unbridled competition.”

“There can be little doubt that, as far as they thought of the matter at all, Marx and Engels were personally homophobic, as shown by an acerbic 1869 exchange of letters on Jean-Baptiste von Schweitzer, a German socialist rival. Schweitzer had been arrested in a park on a morals charge and not only did Marx and Engels refuse to join a committee defending him, they resorted to the cheapest form of bathroom humor in their private comments about the affair.”

“When all capital, all production, all exchange have been brought together in the hands of the nation, private property will disappear of its own accord, money will become superfluous, and production will so expand and man so change that society will be able to slough off whatever of its old economic habits may remain.”
