“Great wits to madness sure are near allied,
And thin partitions do their bounds divide.”
Especially instructive in this respect is Goethe's “Torquato Tasso,” in which he shows us not only the suffering, the martyrdom of genius as such, but also how it constantly passes into madness. Finally, the fact of the direct connection of genius and madness is established by the biographies of great men of genius, such as Rousseau, Byron, and Alfieri, and by anecdotes from the lives of others. On the other hand, I must mention that, by a diligent search in lunatic asylums, I have found individual cases of patients who were unquestionably endowed with great talents, and whose genius distinctly appeared through their madness, which, however, had completely gained the upper hand. Now this cannot be ascribed to chance, for on the one hand the number of mad persons is relatively very small, and on the other hand a person of genius is a phenomenon which is rare beyond all ordinary estimation, and only appears in nature as the greatest exception. It will be sufficient to convince us of this if we compare the number of really great men of genius that the whole of civilised Europe has produced, both in ancient and modern times, with the two hundred and fifty millions who are always living in Europe, and who change entirely every thirty years. In estimating the number of men of outstanding genius, we must of course only count those who have produced works which have retained through all time an enduring value for mankind. I shall not refrain from mentioning, that I have known some persons of decided, though not remarkable, mental superiority, who also showed a slight trace of insanity. It might seem from this that every advance of intellect beyond the ordinary measure, as an abnormal development, disposes to madness. In the meantime, however, I will explain as briefly as possible my view of the purely intellectual ground of the relation between genius and madness, for this will certainly assist the explanation of the real nature of genius, that is to say, of that mental endowment which alone can produce genuine works of art. But this necessitates a brief explanation of madness itself.50
A clear and complete insight into the nature of madness, a correct and distinct conception of what constitutes the difference between the sane and the insane, has, as far as I know, not as yet been found. Neither reason nor understanding can be denied to madmen, for they talk and understand, and often draw very accurate conclusions; they also, as a rule, perceive what is present quite correctly, and apprehend the connection between cause and effect. Visions, like the phantasies of delirium, are no ordinary symptom of madness: delirium falsifies perception, madness the thoughts. For the most part, madmen do not err in the knowledge of what is immediately present; their raving always relates to what is absent and past, and only through these to their connection with what is present. Therefore it seems to me that their malady specially concerns the memory; not indeed that memory fails them entirely, for many of them know a great deal by heart, and sometimes recognise persons whom they have not seen for a long time; but rather that the thread of memory is broken, the continuity of its connection destroyed, and no uniformly connected recollection of the past is possible. Particular scenes of the past are known correctly, just like the particular present; but there are gaps in their recollection which they fill up with fictions, and these are either always the same, in which case they become fixed ideas, and the madness that results is called monomania or melancholy; or they are always different, momentary fancies, and then it is called folly, fatuitas. This is why it is so difficult to find out their former life from lunatics when they enter an asylum. The true and the false are always mixed up in their memory. Although the immediate present is correctly known, it becomes falsified through its fictitious connection with an imaginary past; they therefore regard themselves and others as identical with persons who exist only in their imaginary past; they do not recognise some of their acquaintances at all, and thus while they perceive correctly what is actually present, they have only false conceptions of its relations to what is absent. If the madness reaches a high degree, there is complete absence of memory, so that the madman is quite incapable of any reference to what is absent or past, and is only determined by the caprice of the moment in connection with the fictions which, in his mind, fill the past. In such a case, we are never for a moment safe from violence or murder, unless we constantly make the madman aware of the presence of superior force. The knowledge of the madman has this in common with that of the brute, both are confined to the present. What distinguishes them is that the brute has really no idea of the past as such, though the past acts upon it through the medium of custom, so that, for example, the dog recognises its former master even after years, that is to say, it receives the wonted impression at the sight of him; but of the time that has passed since it saw him it has no recollection. The madman, on the other hand, always carries about in his reason an abstract past, but it is a false past, which exists only for him, and that either constantly, or only for the moment. The influence of this false past prevents the use of the true knowledge of the present which the brute is able to make. The fact that violent mental suffering or unexpected and terrible calamities should often produce madness, I explain in the following manner. All such suffering is as an actual event confined to the present. It is thus merely transitory, and is consequently never excessively heavy; it only becomes unendurably great when it is lasting pain; but as such it exists only in thought, and therefore lies in the memory. If now such a sorrow, such painful knowledge or reflection, is so bitter that it becomes altogether unbearable, and the individual is prostrated under it, then, terrified Nature seizes upon madness as the last resource of life;
