Otto Weininger quotes - page 2
In men of genius, sterile years precede productive years, these again to be followed by sterility, the barren periods being marked by psychological self-depreciation, by the feeling that they are less than other men; times in which the remembrance of the creative periods is a torment, and when they envy those who go about undisturbed by such penalties. Just as his moments of ecstasy are more poignant, so are the periods of depression of a man of genius more intense than those of other men [Wie seine Ekstasen gewaltiger sind als die der anderen, so sind auch seine Depressionen fürchterlicher]. Every great man has such periods, of longer or shorter duration, times in which he loses self-confidence, ... times in which, indeed, he may be sowing the seeds of a future harvest, but which are devoid of the stimulus to production.
Otto Weininger
That which enables man to have a real relation to truth and which removes his temptation to lie, must be something independent of all time, something absolutely unchangeable, which as faithfully reproduces the old as if it were new, because it is permanent itself; it can only be that source in which all discrete experiences unite and which creates from the first a continuous existence. It is what produces the feeling of responsibility which oppresses all men, young and old, as to their actions, which makes them know that they are responsible, which leads to the phenomena of repentance and consciousness of sin, which calls to account before an eternal and ever present self things that are long past, its judgment being subtler and more comprehensive than that of any court of law or of the laws of society, and which is exerted by the individual himself quite independently of all social codes.
