The animal is one with its life activity. It does not distinguish the activity from itself. It is its activity. But man makes hislife activity itself an object of his will and consciousness. He has a conscious life activity. It is not a determination with which he is completely identified.
Karl MarxThe 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 Marx
