Whatever the cause of heterogeneous personality may be, we find the extreme examples of it in the psychopathic temperament. All writers about that temperament make the inner heterogeneity prominent in their descriptions. Frequently, indeed, it is only this trait that leads us to ascribe that temperament to a man at all. A _dégénéré supérieur_ is simply a man of sensibility in many directions, who finds more difficulty than is common in keeping his spiritual house in order and running his furrow straight, because his feelings and impulses are too keen and too discrepant mutually. In the haunting and insistent ideas, in the irrational impulses, the morbid scruples, dreads, and inhibitions which beset the psychopathic temperament when it is thoroughly pronounced, we have exquisite examples of heterogeneous personality. Bunyan had an obsession of the words, "Sell Christ for this, sell him for that, sell him, sell him!" which would run through his mind a hundred times together, until one day out of breath with retorting, "I will not, I will not," he impulsively said, "Let him go if he will," and this loss of the battle kept him in despair for over a year. The lives of the saints are full of such blasphemous obsessions, ascribed invariably to the direct agency of Satan. St. Augustine's case is a classic example of discordant personality. You all remember his half-pagan, half-Christian bringing up at Carthage, his emigration to Rome and Milan, his adoption of Manicheism and subsequent skepticism, and his restless search for truth and purity of life; and finally how, distracted by the struggle between the two souls in his breast, and ashamed of his own weakness of will when so many others whom he knew and knew of had thrown off the shackles of sensuality and dedicated themselves to chastity and the higher life, he heard a voice in the garden say, "Sume, lege" (take and read), and opening the Bible at random, saw the text, "not in chambering and wantonness," etc., which seemed directly sent to his address, and laid the inner storm to rest forever. Augustine's psychological genius has given an account of the trouble of having a divided self which has never been surpassed.
