Friedrich Nietzsche said this quote
“ Remain true to the earth, my brethren, with the power of your virtue! Let your bestowing love and your knowledge be devoted to be the meaning of the earth! . . . Let it not fly away from the earthly and beat against eternal walls with its wings. . . . Lead, like me, the flown-away virtue back to the earth—yes, back to body and life: that it may give to the earth its meaning, a human meaning! ”
