Barth

Love

may be recognised by the fact that it is determined, and indeed determined upon the life-partnership of marriage. Love does not question; it gives an answer. Love does not think; it knows. Love does not hesitate; it acts. Love does not fall into raptures; it is ready to undertake responsibilities. Love puts behind it all the Ifs and Buts, all the conditions, reservations, obscurities and uncertainties that may arise between a man and a woman. Love is not only affinity and attraction; it is union. Love makes these two persons indispensable to each other. - (CD III.4, 221)
