apt to apprehend these too vividly, to behold all in too glaring colours, in too bright a light, and in a fearfully exaggerated form, whereby the individual falls into mere extremes. The following may serve to explain this more accurately. All great theoretical achievements, in whatever sphere they may be, are brought about in this way: Their author directs all the forces of his mind upon one point, in which he lets them unite and concentrate so strongly, firmly, and exclusively that now the whole of the rest of the world vanishes for him, and his object fills all reality. Now this great and powerful concentration which belongs to the privileges of genius sometimes appears for it also in the case of objects of the real world and the events of daily life, which then, brought under such a focus, are magnified to such a monstrous extent that they appear like the flea, which under the solar microscope assumes the stature of an elephant. Hence it arises that highly gifted individuals sometimes are thrown by trifles into violent emotions of the most various kinds, which are incomprehensible to others, who see them transported with grief, joy, care, fear, anger, &c., by things which leave the every‐day man quite composed. Thus, then, the genius lacks _soberness_, which simply consists in this, that one sees in things nothing more than actually belongs to them, especially with reference to our possible ends; therefore no sober‐ minded man can be a genius. With the disadvantages which have been enumerated there is also associated hyper‐sensibility, which an abnormally developed nervous and cerebral system brings with it, and indeed in union with the vehemence and passionateness of will which is certainly characteristic of genius, and which exhibits itself physically as energy of the pulsation of the heart. From all this very easily arises that extravagance of disposition, that vehemence of the emotions, that quick change of mood under prevailing melancholy, which Goethe has presented to us in Tasso. What reasonableness, quiet composure, finished surveyal, certainty and proportionateness of behaviour is shown by the well‐endowed normal man in comparison with the now dreamy absentness, and now passionate excitement of the man of genius, whose inward pain is the mother’s lap of immortal works! To all this must still be added that genius lives essentially alone. It is too rare to find its like with ease, and too different from the rest of men to be their companion. With them it is the will, with him it is knowledge, that predominates; therefore their pleasures are not his, and his are not theirs. They are merely moral beings, and have merely personal relations; he is at the same time a pure intellect, and as such belongs to the whole of humanity. The course of thought of the intellect which is detached from its mother soil, the will, and only returns to it periodically, will soon show itself entirely
