During these years, indeed, he acquired a most remarkable knowledge of Germany; before, he had lived entirely in Prussia, now he was at the centre of the German political system, continually engaged in important negotiations with the other Courts; after a few years there was not a man of importance in German public life whose character and opinions he had not gauged. Further experience only confirmed in him the observations he had made at the beginning, that it was impossible to maintain a good understanding with Austria. The tone of his letters soon changes from doubt and disappointment to settled and determined hostility. In other matters also he found that the world was not the same place it had seemed to him; he had been accustomed to regard the Revolution as the chief danger to be met; at Frankfort he was in the home of it; here for nearly a year the German Assembly had held its meetings; in the neighbouring States of Baden, Hesse, and in the Palatinate, the Republican element was strong; he found them as revolutionary as ever, but he soon learnt to despise rather than fear them: "The population here would be a political volcano if revolutions were made with the mouth; so long as it requires blood and strength they will obey anyone who has courage to command and, if necessary, to draw the sword; they would be dangerous only under cowardly governments. "I have never seen two men fighting in all the two years I have been here. This cowardice does not prevent the people, who are completely devoid of all inner Christianity and all respect for authority, from sympathising with the Revolution." His observations on the character of the South Germans only increased his admiration for the Prussian people and his confidence in the Prussian State.
