and often pathetic sincerity, as by their absurdity and monstrous ignorance of all real relations. Finally, a cardinal mark of degeneration which I have reserved to the last, is mysticism. Colin says:[21] ‘Of all the delirious manifestations peculiar to the hereditarily-afflicted, none indicates the condition more clearly, we think, than mystical delirium, or, when the malady has not reached this point, the being constantly occupied with mystical and religious questions, an exaggerated piety, etc.’ I will not here multiply evidence and quotations. In the following books, where the art and poetry of the times are treated of, I shall find occasion to show the reader that no difference exists between these tendencies and the religious manias observed in nearly all degenerates and sufferers from hereditary mental taint. I have enumerated the most important features characterizing the mental condition of the degenerate. The reader can now judge for himself whether or not the diagnosis ‘degeneration’ is applicable to the originators of the new æsthetic tendencies. It must not for that matter be supposed that degeneration is synonymous with absence of talent. Nearly all the inquirers who have had degenerates under their observation expressly establish the contrary. ‘The degenerate,’ says Legrain,[22] ‘may be a genius. A badly balanced mind is susceptible of the highest conceptions, while, on the other hand, one meets in the same mind with traits of meanness and pettiness all the more striking from the fact that they co-exist with the most brilliant qualities.’ We shall find this reservation in all authors who have contributed to the natural history of the degenerate. ‘As regards their intellect, they can,’ says Roubinovitch,[23] ‘attain to a high degree of development, but from a moral point of view their existence is completely deranged.... A degenerate will employ his brilliant faculties quite as well in the service of some grand object as in the satisfaction of the basest propensities.’ Lombroso[24] has cited a large number of undoubted geniuses who were equally undoubted mattoids, graphomaniacs, or pronounced lunatics; and the utterance of a French savant, Guérinsen, ‘Genius is a disease of the nerves,’ has become a ‘winged word.’ This expression was imprudent, for it gave ignorant babblers a pretext, and apparently a right, to talk of exaggeration, and to contemn experts in nervous and mental diseases, because they professedly saw a lunatic in everyone who ventured to be something more than the most ordinary, characterless, average being. Science does not assert that every genius is a lunatic; there are some geniuses of superabundant power whose high privilege consists in the possession of one or other extraordinarily developed faculty, without the rest of their faculties falling short of the average standard. Just as little, naturally, is every lunatic a genius; most of them, even if
