It is also good to love: because love is difficult. For one human being to love another human being: that is perhaps the most difficult task that has been entrusted to us, the ultimate task, the final test and proof, the work for which all other work is merely preparation. That is why young people, who are beginners in everything, are not yet capable of love: it is something they must learn. With their whole being, with all their forces, gathered around their solitary, anxious, upward-beating heart, they must learn to love. But learning-time is always a long, secluded time, and therefore loving, for a long time ahead and far on into life, is: solitude, a heightened and deepened kind of aloneness for the person who loves. Loving does not at first mean merging, surrendering, and uniting with another person (for what would a union be of two people who are unclarified, unfinished, and still incoherent?), it is a high inducement for the individual to ripen, to become something in himself, to become world, to become world in himself for the sake of another person; it is a great, demanding claim on him, something that chooses him and calls him to vast distances. Only in this sense, as the task of working on themselves ("to hearken and to hammer day and night"), may young people use the love that is given to them. Merging and surrendering and every kind of communion is not for them (who must still, for a long, long time, save and gather themselves); it is the ultimate, is perhaps that for which human lives are as yet barely large enough.
But this is what young people are so often and so disastrously wrong in doing: they (who by their very nature are impatient) fling themselves at each other when love takes hold of them, they scatter themselves, just as they are, in all their messiness, disorder, bewilderment. And what can happen then? What can life do with this heap of half-broken things that they call their communion and that they would like to call their happiness, if that were possible, and their future? And so each of them loses himself for the sake of the other person, and loses the other, and many others who still wanted to come. And loses the vast distances and possibilities, gives up the approaching and fleeing of gentle, prescient Things in exchange for an unfruitful confusion, out of which nothing more can come; nothing but a bit of disgust, disappointment, and poverty, and the escape into one of the many conventions that have been put up in great numbers like public shelters on this most dangerous road. No area of human experience is so extensively provided with conventions as this one is: there are life-preservers of the most varied invention, boats and water wings; society has been able to create refuges of every sort, for since it preferred to take love life as an amusement, it also had to give it an easy form, cheap, safe, and sure, as public amusements are.
