The Communists disdain to conceal their views and aims. They open declare that their ends can be attained only by the forcible overthrow of all existing social conditions. Let the ruling classes tremble at a Communistic revolution. The proletarians have nothing to lose but their chains. They have a world to win. WORKING MEN OF ALL COUNTRIES, UNITE!
Karl MarxAll social life is essentially practical. All mysterious which lead theory to mysticism find their rational solution in human practice and in the comprehension of the practice.
