“...[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).”

German philosopher and revolutionary socialist

Karl Marx was a German philosopher, journalist, political theorist, and revolutionary socialist of the 19th century. He is known for shaping modern socialist thought and for his analysis of capitalism and class struggle. He developed historical materialism, arguing that social change is driven by material conditions and conflict between classes. He also co-wrote The Communist Manifesto with Friedrich Engels and spent much of his work on a critique of political economy in Das Kapital. His ideas, later gathered under the name Marxism, became highly influential in politics, scholarship, and revolutionary movements.
