But the rapid development of Polish industry,outstripping that of Russia, is in its turn a new proof of the inexhaustible vitality of the Polish people and a new guarantee of its impending national restoration.And the restoration of an independent and strong Poland is a matter which concerns not only the Poles but all of us. A sincere international collaboration of the European nations is possible only if each of these nations is fully autonomous in its own house.The Revolution of 1848, which under the banner of the proletariat, after all, merely let the proletarian fighters do the work of the bourgeoisie, also secured the independence of Italy, Germany and Hungary through its testamentary executors, Louis Bonaparte and Bismarck; but Poland, which since 1792 had done more for the Revolution than all these three together,was left to its own resources when it succumbed in 1863 to a tenfold greater Russian force. The nobility could neither maintain nor regain Polish independence;today, to the bourgeoisie, this independence is, to say the last, immaterial. Nevertheless, it is a necessity for the harmonious collaboration of the European nations.It can be gained only by the young Polish proletariat, and in its hands it is secure. For the workers of all the rest of Europe need the independence of Poland just as much as the Polish workers themselves.
