I have made hardly any changes in the book as it first appeared, beyond the correction of a few verbal slips. The important political developments which have occurred during the last eighteen months in the English Parliament, in Turkey, Persia, and India, and in Germany, have not altered my conclusions as to the psychological problems raised by modern forms of government; and it would involve an impossible and undesirable amount of rewriting to substitute 'up-to-date' illustrations for those which I drew from the current events of 1907 and 1908. I should desire to add to the books recommended above Mr. W. M'Dougall's Social Psychology, with special reference to his analysis of Instinct.
