When under any kind of noxious influences an organism becomes debilitated, its successors will not resemble the healthy, normal type of the species, with capacities for development, but will form a new sub-species, which, like all others, possesses the capacity of transmitting to its offspring, in a continuously increasing degree, its peculiarities, these being morbid deviations from the normal form—gaps in development, malformations and infirmities. That which distinguishes degeneracy from the formation of new species (phylogeny) is, that the morbid variation does not continuously subsist and propagate itself, like one that is healthy, but, fortunately, is soon rendered sterile, and after a few generations often dies out before it reaches the lowest grade of organic degradation.[6]

Degeneracy betrays itself among men in certain physical characteristics, which are denominated ‘stigmata,’ or brand-marks—an unfortunate term derived from a false idea, as if degeneracy were necessarily the consequence of a fault, and the indication of it a punishment. Such stigmata consist of deformities, multiple and stunted growths in the first line of asymmetry, the unequal development of the two halves of the face and cranium; then imperfection in the development of the external ear, which is conspicuous for its enormous size, or protrudes from the head, like a handle, and the lobe of which is either lacking or adhering to the head, and the helix of which is not involuted; further, squint-eyes, hare-lips, irregularities in the form and position of the teeth; pointed or flat palates, webbed or supernumerary fingers (syn-and polydactylia), etc. In the book from which I have quoted, Morel gives a list of the anatomical phenomena of degeneracy, which later observers have largely extended. In particular, Lombroso[7] has conspicuously broadened our knowledge of stigmata, but he apportions them merely to his ‘born criminals’—a limitation which from the very scientific standpoint of Lombroso himself cannot be justified, his ‘born criminals’ being nothing but a subdivision of degenerates. Féré[8] expresses this very emphatically when he says, ‘Vice, crime and madness are only distinguished from each other by social prejudices.’

There might be a sure means of proving that the application of the term ‘degenerates’ to the originators of all the fin-de-siècle movements in art and literature is not arbitrary, that it is no baseless conceit, but a fact; and that would be a careful physical examination of the persons concerned, and an inquiry into their pedigree. In almost all cases, relatives would be met with who were undoubtedly degenerate, and one or more stigmata discovered which would indisputably establish the diagnosis of ‘Degeneration.’ Of course, from human consideration, the result of such an inquiry could often not be made public; and he alone would be convinced who should be able to undertake it himself.

Science, however, has found, together with these physical stigmata, others of a mental order, which betoken degeneracy quite as clearly as the former; and they allow of an easy demonstration from all the vital manifestations, and, in particular, from all the works of degenerates, so that it is not necessary to measure the cranium of an author, or to see the lobe of a painter’s ear, in order to recognise the fact that he belongs to the class of degenerates.

Quite a number of different designations have been found for these persons. Maudsley and Ball call them ‘Borderland dwellers’—that is to say, dwellers on the borderland between reason and pronounced madness. Magnan gives to them the name of ‘higher degenerates’ (dégénérés supérieurs), and Lombroso speaks of ‘mattoids’ (from matto, the Italian for insane), and ‘graphomaniacs,’ under which he classifies those semi-insane persons who feel a strong impulse to write. In spite, however, of this variety of nomenclature, it is a question simply of one single species of individuals, who betray their fellowship by the similarity of their mental physiognomy.

In the mental development of degenerates, we meet with the same irregularity that we have observed in their physical growth. The asymmetry of face and cranium finds, as it were, its counterpart in their mental faculties. Some of the latter are completely stunted, others morbidly exaggerated. That which nearly all degenerates lack is the sense of morality and of right and wrong. For them there exists no law, no decency, no modesty. In order to satisfy any momentary impulse, or inclination, or caprice, they commit crimes and trespasses with the greatest calmness and self-complacency, and do not comprehend that other persons take offence thereat. When this phenomenon is present in a high degree, we speak of ‘moral insanity’ with Maudsley;[9] there are, nevertheless, lower stages in which the degenerate does not, perhaps, himself commit any act which will bring him into conflict with the criminal code, but at least asserts the theoretical legitimacy of crime; seeks, with philosophically sounding fustian, to prove that ‘good’ and ‘evil,’ virtue and vice, are arbitrary distinctions; goes into raptures over evildoers and their deeds; professes to discover beauties in the lowest and most repulsive things; and tries to awaken interest in, and so-called ‘comprehension’ of, every bestiality. The two psychological roots of moral insanity, in all its degrees of development, are, firstly, unbounded egoism,[10] and, secondly, impulsiveness[11]i.e., inability to resist a sudden impulse to any deed; and these characteristics also constitute the chief intellectual stigmata of degenerates. In the following sections of this work, I shall find occasion to show on what organic grounds, and in consequence of what peculiarities of their brain and nervous system, degenerates are necessarily egoistical and impulsive. In these introductory remarks I would wish only to point out the stigma itself.

Another mental stigma of degenerates is their emotionalism. Morel[12] has even wished to make this peculiarity their chief characteristic—erroneously, it seems to me, for it is present in the same degree among hysterics, and, indeed, is to be found in perfectly healthy persons, who, from any transient cause, such as illness, exhaustion, or any mental shock, have been temporarily weakened. Nevertheless it is a phenomenon rarely absent in a degenerate. He laughs until he sheds tears, or weeps copiously without adequate occasion; a commonplace line of poetry or of prose sends a shudder down his back; he falls into raptures before indifferent pictures or statues; and music especially, even the most insipid and least commendable, arouses in him the most vehement emotions. He is quite proud of being so vibrant a musical instrument, and boasts that where the Philistine remains completely cold, he feels his inner self confounded, the depths of his being broken up, and the bliss of the Beautiful possessing him to the tips of his fingers. His excitability appears to him a mark of superiority; he believes himself to be possessed by a peculiar insight lacking in other mortals, and he is fain to despise the vulgar herd for the dulness and narrowness of their minds. The unhappy creature does not suspect that he is conceited about a disease and boasting of a derangement of the mind; and certain silly critics, when, through fear of being pronounced deficient in comprehension, they make desperate efforts to share the emotions of a degenerate in regard to some insipid or ridiculous production, or when they praise in exaggerated expressions the beauties which the degenerate asserts he finds therein, are unconsciously simulating one of the stigmata of semi-insanity.

Besides moral insanity and emotionalism, there is to be observed in the degenerate a condition of mental weakness and despondency, which, according to the circumstances of his life, assumes the form of pessimism, a vague fear of all men, and of the entire phenomenon of the universe, or self-abhorrence. ‘These patients,’ says Morel,[13] ‘feel perpetually compelled ... to commiserate themselves, to sob, to repeat with the most desperate monotony the same questions and words. They have delirious presentations of ruin and damnation, and all sorts of imaginary fears.’ ‘Ennui never quits me,’ said a patient of this kind, whose case Roubinovitch[14] describes, ‘ennui of myself.’ ‘Among moral stigmata,’ says the same author,[15] ‘there are also to be specified those undefinable apprehensions manifested by degenerates when they see, smell, or touch any object.’ And he further[16] calls to notice ‘their unconscious fear of everything and everyone.’ In this picture of the sufferer from melancholia; downcast, sombre, despairing of himself and the world, tortured by fear of the Unknown, menaced by undefined but dreadful dangers, we recognise in every detail the man of the Dusk of the Nations and the fin-de-siècle frame of mind, described in the first chapter.

With this characteristic dejectedness of the degenerate, there is combined, as a rule, a disinclination to action of any kind, attaining possibly to abhorrence of activity and powerlessness to will (aboulia). Now, it is a peculiarity of the human mind, known to every psychologist, that, inasmuch as the law of causality governs a man’s whole thought, he imputes a rational basis to all his own decisions. This was prettily expressed by Spinoza when he said: ‘If a stone flung by a human hand could think, it would certainly imagine that it flew because it wished to fly.’ Many mental conditions and operations of which we become conscious are the result of causes which do not reach our consciousness. In this case we fabricate causes a posteriori for them, satisfying our mental need of distinct causality, and we have no trouble in persuading ourselves that we have now truly explained them. The degenerate who shuns action, and is without will-power, has no suspicion that his incapacity for action is a consequence of his inherited deficiency of brain. He deceives himself into believing that he despises action from free determination, and takes pleasure in inactivity; and, in order to justify himself in his own eyes, he constructs a philosophy of renunciation and of contempt for the world and men, asserts that he has convinced himself of the excellence of Quietism, calls himself with consummate self-consciousness a Buddhist, and praises Nirvana in poetically eloquent phrases as the highest and worthiest ideal of the human mind. The degenerate and insane are the predestined disciples of Schopenhauer and Hartmann, and need only to acquire a knowledge of Buddhism to become converts to it.
