Nietzsche’s recipe for wisdom: “Brave, unconcerned, mocking” with “joyful distrust” and “love of irony”, but also with “underground seriousness”.
In this torn desert world there is no love because pleasure and desire play the greatest roles, yet without love your daily life has no meaning. And you cannot have love if there is no beauty. Beauty is not something you see—not a beautiful tree, a beautiful picture, a beautiful building, or a beautiful woman. There is beauty only when your heart and mind know what love is. Without love and that sense of beauty there is no virtue, and you know very well that, do what you will, improve society, feed the poor, you will only be creating more mischief, for without love there is only ugliness and poverty in your heart and mind. But when there is love and beauty, whatever you do is right, whatever you do is in order. If you know how to love, then you can do what you like because it will solve all other problems.
