The proposition which I set myself to prove may now be taken as demonstrated. In the civilized world there obviously prevails a twilight mood which finds expression, amongst other ways, in all sorts of odd æsthetic fashions. All these new tendencies, realism or naturalism, ‘decadentism,’ neo-mysticism, and their sub-varieties, are manifestations of degeneration and hysteria, and identical with the mental stigmata which the observations of clinicists have unquestionably established as belonging to these. But both degeneration and hysteria are the consequences of the excessive organic wear and tear suffered by the nations through the immense demands on their activity, and through the rank growth of large towns. Led by this firmly linked chain of causes and effects, everyone capable of logical thought will recognise that he commits a serious error if, in the æsthetic schools which have sprung up in the last few years, he sees the heralds of a new era. They do not direct us to the future, but point backwards to times past. Their word is no ecstatic prophecy, but the senseless stammering and babbling of deranged minds, and what the ignorant hold to be the outbursts of gushing, youthful vigour and turbulent constructive impulses are really nothing but the convulsions and spasms of exhaustion. We should not allow ourselves to be deceived by certain catch-words, frequently uttered in the works of these professed innovators. They talk of socialism, of emancipation of the mind, etc., and thereby create the outward show of being deeply imbued with the thoughts and struggles of the times. But this is empty sham. The catch-words in vogue are scattered through the works without internal sequence, and the struggles of the times are merely painted on the outside. It is a phenomenon observed in every kind of mania, that it receives its special colouring from the degree of culture of the invalid, and from the views prevailing at the times in which he lived. The Catholic who is a prey to megalomania fancies he is the Pope; the Jew, that he is the Messiah; the German, that he is the Emperor or a field-marshal; the Frenchman, that he is the President of the Republic. In the persecution-mania, the invalid of former days complained of the wickedness and knavery of magicians and witches; to-day he grumbles because his imaginary enemies send electric streams through his nerves, and torment him with magnetism. The degenerates of to-day chatter of Socialism and Darwinism, because these words, and, in the best case, the ideas connected with these, are in current use. These so-called socialist and free-thinking works of the degenerate as little advance the development of society towards more equitable economic forms, and more rational views of the relations among phenomena, as the complaints and descriptions of an individual suffering from persecution-mania, and who holds electricity responsible for his disagreeable sensations,
