馬恩的這篇著作，據說是給工人階級寫的，所以很淺顯易懂。原著發表於1848年，但這段是從1888年英譯本來的。
"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!"
注意這裏的用詞是：forceful overthrow，而不是暴力。
