↑ "You know that the institutions, mores, and traditions of various countries must be taken into consideration, and we do not deny that there are countries – such as America, England, and if I were more familiar with your institutions, I would perhaps also add Holland – where the workers can attain their goal by peaceful means.

La Liberté Speech delivered by Karl Marx on 8 September 1872, in Amsterdam
