马恩的这篇著作，据说是给工人阶级写的，所以很浅显易懂。原著发表于1848年，但这段是从1888年英译本来的。
"In short, the Communists everywhere support every revolutionary movement against the existing social and political order of things.
In all these movements they bring to the front, as the leading question in each, the property question, no matter what its degree of development at the time.
Finally, they labour everywhere for the union and agreement of the democratic parties of all countries.
The Communists disdain to conceal their views and aims.
They openly 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!"
注意这里的用词是：forceful overthrow，而不是暴力。
