All the symptoms enumerated are the consequences of states of fatigue and exhaustion, and these, again, are the effect of contemporary civilization, of the vertigo and whirl of our frenzied life, the vastly increased number of sense impressions and organic reactions, and therefore of perceptions, judgments, and motor impulses, which at present are forced into a given unity of time. To this general cause of contemporary pathological phenomena, one may be added special to France. By the frightful loss of blood which the body of the French people suffered during the twenty years of the Napoleonic wars, by the violent moral upheavals to which they were subjected in the great Revolution and during the imperial epic, they found themselves exceedingly ill-prepared for the impact of the great discoveries of the century, and sustained by these a more violent shock than other nations more robust and more capable of resistance. Upon this nation, nervously strained and predestined to morbid derangement, there broke the awful catastrophe of 1870. It had, with a self-satisfaction which almost attained to megalomania, believed itself the first nation in the world; it now saw itself suddenly humiliated and crushed. All its convictions abruptly crumbled to pieces. Every single Frenchman suffered reverses of fortune, lost some members of his family, and felt himself personally robbed of his dearest conceptions, nay, even of his honour. The whole people fell into the condition of a man suddenly visited by a crushing blow of destiny, in his fortune, his position, his family, his reputation, even in his self-respect. Thousands lost their reason. In Paris a veritable epidemic of mental diseases was observed, for which a special name was found--_la folie obsidionale_, ‘siege-madness.’ And even those who did not at once succumb to mental derangement, suffered lasting injury to their nervous system. This explains why hysteria and neurasthenia are much more frequent in France, and appear under such a greater variety of forms, and why they can be studied far more closely in this country than anywhere else. But it explains, too, that it is precisely in France that the craziest fashions in art and literature would necessarily arise, and that it is precisely there that the morbid exhaustion of which we have spoken became for the first time sufficiently distinct to consciousness to allow a special name to be coined for it, namely, the designation of _fin-de-siècle_.
