We must go a step farther and say that not only the mystics among the degenerate, but in the main all the degenerate, of whatever nature they may be, are moulded from the same clay. They all show the same lacunæ, inequalities, and malformations in intellectual capacity, the same psychic and somatic stigmata. If, then, anyone, having a certain number of degenerate subjects to judge from, were to bring into prominence and represent as their exclusive peculiarity merely mystical thought in some, merely erotic emotionalism in others, merely vague, barren, fraternal love and a mania for regenerating the world, or else merely an impulsion to commit acts of a criminal nature, etc., he would manifestly be seeing only one side of the phenomenon, and taking no account of the rest. One or another stigma of degeneration may, in a given case, be especially apparent; but, on duly careful inspection, the presence of all the others, or, at least, indications of them, will be discerned.

To the celebrated French alienist, Esquirol, is due the signal merit of having discovered that there are forms of mental derangement in which thought proceeds apparently in a perfectly rational manner, but in which, in the midst of intelligent and logical cerebral activity, some insane presentations appear, like erratic boulders, thus enabling us to recognise the subject as mentally diseased. But Esquirol has committed the fault of not digging deep enough; his observation is too much on the surface. It was through this that he came to introduce into science the notion of ‘monomania,’ that is, of well-delimitated, partial madness, of an isolated, fixed idea beside which all the rest of the intellectual life operates with sanity. This was an error. There is no monomania. Esquirol’s own pupil, the elder Falret, has sufficiently proved it, and our Westphal, from whose other merits I have no wish to detract, was far from standing in the forefront of research, when, half a century after Esquirol, and thirty years after Falret, he still described the ‘fear of space,’ or agoraphobia, as a special mental malady, or kind of monomania. What is apparently monomania is in reality an indication of a profound organic disorder which never reveals itself by one single phase of folly. A fixed idea never exists in isolation.[230] It is always accompanied by other irregularities of thought and feeling, which, it is true, at a cursory glance, may not be so distinctly remarked as the more strongly developed insane idea. Recent clinical observation has discovered a long series of similar fixed ideas or ‘monomanias,’ and recognised the fact that they are one and all the consequence of a fundamental disposition of the organism, viz., of its degeneration. It was unnecessary for Magnan to give a special name to each symptom of degeneration, and to draw up in array, with almost comical effect, the host of ‘phobias’ and ‘manias.’ Agoraphobia (fear of open space), claustrophobia (fear of enclosed space), rupophobia (fear of dirt), iophobia (fear of poison), nosophobia (fear of sickness), aichmophobia (fear of pointed objects), belenophobia (fear of needles), cremnophobia (fear of abysses), trichophobia (fear of hair), onomatomania (folly of words or names), pyromania (incendiary madness), kleptomania (madness for theft), dipsomania (madness for drink), erotomania (love madness), arithmomania (madness of numbers), oniomania (madness for buying), etc. This list might be lengthened at pleasure, and enriched by nearly all the roots of the Greek dictionary. It is simply philologico-medical trifling. None of the disorders discovered and described by Magnan and his pupils, and decorated with a sonorous Greek name, forms an independent entity, and appears separately; and Morel is right in disregarding as unessential all these varied manifestations of a morbid cerebral activity, and adhering to the principal phenomenon which lies at the base of all the ‘phobias’ and ‘manias,’ namely, the great emotionalism of the degenerate.[231] If to emotionalism, or an excessive excitability, he had added the cerebral debility, which implies feebleness of perception, will, memory, judgment, as well as inattention and instability, he would have exhaustively characterized the nature of degeneration, and perhaps prevented psychiatry from being stuffed with a crowd of useless and disturbing designations. Kowalewski approached much nearer to the truth in his well-known treatise,[232] where he has represented all the mental disorders of the degenerate as one single malady, which merely presents different degrees of intensity, and which induces in its mildest form neurasthenia; under a graver aspect impulsions and groundless anxieties; and, in its most serious form, the madness of brooding thought or doubt. Within these limits may be ranged all the particular ‘manias’ and ‘phobias’ which at present swarm in the literature of mental therapeutics.

But if it be untenable to make a particular malady out of every symptom in which the fundamental disorder (i.e., degeneration) shows itself, it should not, on the other hand, be ignored that among certain of the degenerate a group of morbid phenomena distinctly predominates, without involving the absence of the other groups. Thus, it is permissible to distinguish among them certain principal species, notably, beside the mystics, of whom we have studied the most remarkable representatives in contemporary art and poetry, the ego-maniacs (Ichsüchtigen). It is not from affectation that I use this word instead of the terms ‘egoism’ (Selbstsucht) and ‘egoist,’ so generally employed. Egoism is a lack of amiability, a defect in education, perhaps a fault of character, a proof of insufficiently developed morality, but it is not a disease. The egoist is quite able to look after himself in life, and hold his place in society; he is often also, when the attainment of low ends only is in view, even more capable than the superior and nobler man, who has inured himself to self-abnegation. The ego-maniac, on the contrary, is an invalid who does not see things as they are, does not understand the world, and cannot take up a right attitude towards it. The difference I make in German between Ichsucht and Selbstsucht, the French also make in their language, where a careful writer will never confound the word ‘egotisme,’ borrowed from the English, with ‘egoïsme’—that is, selfishness.

Of course the reader to whom the mental physiognomy of ego-maniacs is shown ought always to remember that, if the principal representatives of this species and of that of the mystics are characterized with sufficient clearness, the confines of the latter type are fluctuating. The ego-maniacs are, on the one hand, at once mystics, erotics, and, though it seems paradoxical, even affect occasionally an appearance of philanthropy; among the mystics, on the other hand, we frequently meet with a strongly-developed ego-mania. There are certain specimens among the degenerate in whom all the disorders are produced to such an equal degree that it is doubtful whether they ought to be classed with the mystics or the ego-maniacs. As a general rule, however, co-ordination under one class or the other will not be very difficult.

That egoism is a salient feature in the character of the degenerate has been unanimously confirmed by all observers. ‘The degenerate neither knows nor takes interest in anything but himself,’ says Roubinovitch;[233] and Legrain[234] asserts that he ‘has ... only one occupation, that of satisfying his appetites.’ This peculiarity establishes a bond which unites the highest of the degenerate to the lowest, the insane genius to the feeble mental cripple. ‘All delirious geniuses,’ remarks Lombroso, ‘are very much captivated by, and preoccupied with, their own selves,’[235] and Sollier writes on the subject of their antipodes, the imbeciles: ‘Undisciplined as they are, they obey only through fear, are often violent, especially to those who are weaker than themselves, humble and submissive towards those they feel to be stronger. They are without affection, egoistic in the highest degree, braggarts.’[236]

The clinicist is satisfied with indicating the fact of this characteristic egoism, but for ourselves we wish further to investigate what are its organic roots, why the degenerate must be more than egoistic, why he must be an ego-maniac, and cannot be otherwise.

In order to understand how the consciousness of the ‘I’ (morbidly exaggerated and frequently increasing to megalomania) originates, we must recall how the healthy consciousness of the ‘I’ is formed.

It is, of course, not my intention here to treat of the whole theory of cognition. It is only the most important results of this science, so highly developed in the present day, that can find place in this work.

It has become a philosophical commonplace that we know directly only those changes which take place in our own organism. If, in spite of this, we are able to form an image of the external world surrounding us, from perceptions derived only from within, it is because we trace the changes in our organism which we have perceived to causes exterior to it; and from the nature and force of the changes taking place in our organism draw conclusions as to the nature and force of the external events causing them.

How we come in general to assume that there is something exterior, and that changes perceived by us only in our organism can have causes which are not in the organism itself, is a question over which metaphysics has cudgelled its brain for centuries. So little has it found an answer, that, in order to put an end to this difficulty anyhow, it has simply denied the very question, and jumped to the conclusion that the ‘I’ has actually no knowledge of a ‘not-I,’ of an external world, and cannot have it because there is no external world at all, that what we so call is a creation of our mind, and exists only in our thought as a presentation, but not outside our ‘I’ as a reality.
