As I plodded back and forth I reflected miserably upon my own political rootlessness, in a world where politics is so important. When I am with Tories I am a violent advocate of reform; when I am with reformers I hold forth on the value of tradition and stability. When I am with communists I become a royalist - almost a Jacobite; when I am with socialists I am an advocate of free trade, private enterprise and laissez-faire.
