The most interesting acquaintanceship I have struck up here is that of Colonel Lapinski. He is without doubt the cleverest Pole - besides being an homme d'action [man of action] - that I have ever met. His sympathies are all on the German side, though in manners and speech he is also a Frenchman. He cares nothing for the struggle of nationalities and only knows the racial struggle. He hates all Orientals, among whom he numbers Russians Turks, Greeks, Armenians, etc., with equal impartiality.... His aim now is to raise a German legion in London.

But Christ is alienated God and alienated man. God has value only insofar as he represents Christ, and man has value only insofar as he represents Christ. It is the same with money.
