I am deeply sensitive to the spell of nationalism. I can play about thirty Bohemian folk songs... on my mouth-organ. My oldest friend, who is Czech and a patriot, cannot bear to hear me play them because he says I do it in such a schmalzy way, 'crying into the mouth organ'. I do not think I could have written the book on nationalism which I did write, were I not capable of crying, with the help of a little alcohol, over folk songs, which happen to be my favourite form of music.
