Ludwig Feuerbach,
The Essence of Christianity
“ But love is also the idealism of nature—love is also spirit, esprit. Love alone makes the nightingale a songstress; love alone gives the plant its corolla. And what wonders does not love work in our social life! What faith, creed, opinion separates, love unites. Love even, humorously enough, identifies the high noblesse with the people. What the old mystics said of God, that he is the highest and yet the commonest being, applies in truth to love, and that not a visionary, imaginary love—no! a real love, a love which has flesh and blood, which vibrates as an almighty force through all living. ”
