“The foundation of irreligious criticism is: Man makes religion, religion does not make man. Religion is, indeed, the self-consciousness and self-esteem of man who has either not yet won through to himself, or has already lost himself again. But man is no abstract being squatting outside the world. Man is the world of man – state, society. This state and this society produce religion, which is an inverted consciousness of the world, because they are an inverted world...Religious suffering is, at one and the same time, the expression of real suffering and a protest against real suffering. Religion is the sigh of the oppressed creature, the heart of a heartless world, and the soul of soulless conditions. It is the opium of the people.The abolition of religion as the illusory happiness of the people is the demand for their real happiness. To call on them to give up their illusions about their condition is to call on them to give up a condition that requires illusions. The criticism of religion is, therefore, in embryo, the criticism of that vale of tears of which religion is the halo.Criticism has plucked the imaginary flowers on the chain not in order that man shall continue to bear that chain without fantasy or consolation, but so that he shall throw off the chain and pluck the living flower. The criticism of religion disillusions man, so that he will think, act, and fashion his reality like a man who has discarded his illusions and regained his senses, so that he will move around himself as his own true Sun. Religion is only the illusory Sun which revolves around man as long as he does not revolve around himself.”

“Capitalism: Teach a man to fish, but the fish he catches aren't his. They belong to the person paying him to fish, and if he's lucky, he might get paid enough to buy a few fish for himself.”

“I hate vodka. It is the second worst thing to have come out of Russia, after communism - which isn't Russian anyway, Karl Marx was Russian.”

“Calvin:"It says here that 'religion is the opiate of the masses.'...what do you suppose that means?"Television: "...it means that Karl Marx hadn't seen anything yet”

“In addition, historical interpretations of this period in China have been shaped by Karl Marx's writings on this subject. Despite his anti-imperialist stance, Marx often uses racist expressions, such as "barbarous"and "hereditary stupidity," to describe Chinese culture and people.”

“As Karl Marx once noted: 'Hegel remarks somewhere that all great, world-historical facts and personages occur, as it were, twice. He forgot to add: the first time as tragedy, the second as farce.' William Jennings Bryan and the Scopes trial was a tragedy. The creationists and intelligent design theorists are a farce.”

“What exclusively determines the magnitude of the value of any article is therefore the amount of labour socially necessary, or the labour-time socially necessary for its production.”

“A use-value, or useful article, therefore, has value only because abstract human labour is objectified or materialized in it. How, then, is the magnitude of this value to be measured? By means of the quantity of the "value-forming substance", the labour, contained in the article. This quantity is measured by its duration, and the labour-time is itself measured on the particular scale of hours, days etc.”

“As exchange-values, all commodities are merely definite quantities of congealed labour-time.”
