"The philosophers have only interpreted the world,..." - Quote by Karl Marx

“Change the economic base and you will change human beings.”

“The labour-power is a commodity , not capital, in the hands of the labourer, and it constitutes for him a revenue so long as he can continuously repeat its sale; it functions as capital after its sale, in the hands of the capitalist, during the process of production itself.”

“In bourgeois society capital is independent and has individuality, while the living person is dependent and has no individuality.”

“"Why, what I may think after dinner," returns Mr. Jobling, "is one thing, my dear Guppy, and what I may think before dinner is another thing."”

“Everything changes and nothing remains still.”

“Society is a wave. The wave moves onward, but the water of which it is composed does not.”

“The world, nature, human beings, do not move like machines. The edges are never clear-cut, but always frayed. Nature never draws a line without smudging it.”

“Underneath the reality in which we live and have our being, another altogether different reality lies concealed.”

“Philosophy consists very largely of one philosopher arguing that all others are jackasses. He usually proves it, and I should add that he also usually proves that he is one himself.”
