Since this was written the influence of several generations of town-life in immunizing a stock to the evils of that life (though without reference to prostitution) has been set forth by Reibmayr, Die Entwicklungsgeschichte des Talentes und Genies, 1908, vol. ii, pp. 73 et seq.
In France this intimacy is embodied in the delicious privilege of tutoiement. "The mystery of tutoiement!" exclaims Ernest La Jennesse in L'Holocauste: "Barriers broken down, veils drawn away, and the ease of existence! At a time when I was very lonely, and trying to grow accustomed to Paris and to misfortune, I would go miles—on foot, naturally—to see a girl cousin and an aunt, merely to have something to tutoyer. Sometimes they were not at home, and I had to come back with my tu, my thirst for confidence and familiarity and brotherliness."
