Without slavery, no Greek state, no Greek art and science, without slavery, no Roman Empire. But without the basis laid by Hellenism and the Roman Empire, also no modern Europe. We should never forget that our whole economic, political and intellectual development presupposes a state of things in which slavery was as necessary as it was universally recognised. In this sense we are entitled to say: Without the slavery of antiquity no modern socialism.

The more I think about it, the more obvious it becomes to me that the Poles are une nation foutue [a finished nation] who can only continue to serve a purpose until such time as Russia herself becomes caught up into the agrarian revolution. From that moment Poland will have absolutely no raison d'étre any more. The Poles' sole contribution to history has been to indulge in foolish pranks at once valiant and provocative. Nor can a single moment be cited when Poland, even if only by comparison with Russia, has successfully represented progress or done anything of historical significance.
