Experience praises the most happy the one who made the most people happy. – 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

It is not history which uses men as a means of achieving – as if it were an individual person – its own ends. History is nothing but the activity of men in pursuit of their ends. – Karl Marx
