FOURTH BOOK: THE WORLD AS WILL009
This exposition of the significance and inner nature of the bad, which as mere feeling, i.e., not as distinct, abstract knowledge, is the content of remorse, will gain distinctness and completeness by the similar consideration of the good as a quality of human will, and finally of absolute resignation and holiness, which proceeds from it when it has attained its highest grade. For opposites always throw light upon each other, and the day at once reveals both itself and the night, as Spinoza admirably remarks.
