About Karl Marx:
Karl Marx was a philosopher, economist, sociologist, journalist, and revolutionary socialist. Born in Germany, he later became stateless and spent much of his life in London in the United Kingdom. Marx's work in economics laid the basis for much of the current understanding of labour and its relation to capital, and subsequent economic thought. He published numerous books during his lifetime, the most notable being The Communist Manifesto (1848) and Das Kapital (1867–1894).
The product of mental labor - science - always stands far below its value, because the labor-time necessary to reproduce it has no relation at all to the labor-time required for its original production.Karl Marx
In a higher phase of communist society... only then can the narrow horizon of bourgeois right be fully left behind and society inscribe on its banners: from each according to his ability, to each according to his needs.Karl Marx
Capitalist production, therefore, develops technology, and the combining together of various processes into a social whole, only by sapping the original sources of all wealth - the soil and the labourer.Karl Marx
Money is the universal, self-constituted value of all things. Hence it has robbed the whole world... of its proper value. Money is the alienated essence of man's labour and life, and this alien essence dominates him as he worships it.Karl Marx
