Every adult life could be said to be defined by two great love stories. The first - the story of our quest for sexual love - is well known and well charted, its vagaries form the staple of music and literature, it is socially accepted and celebrated. The second - the story of our quest for love from the world - is a more secret and shameful tale. If mentioned, it tends to be in caustic, mocking terms, as something of interest chiefly to envious or deficient souls, or else the drive for status is interpreted in an economic sense alone. And yet this second love story is no less intense than the first, it is no less complicated, important or universal, and its setbacks are no less painful. There is heartbreak here too.

There are few things humans are more dedicated to than unhappiness. Had we been placed on earth by a malign creator for the exclusive purpose of suffering, we would have good reason to congratulate ourselves on our enthusiastic response to the task. Reasons to be inconsolable abound: the frailty of our bodies, the fickleness of love, the insincerities of social life, the compromises of friendship, the deadening effects of habit. In the face of such persistent ills, we might naturally expect that no event would be awaited with greater anticipation than the moment of our own extinction.

Only as we mature does affection begin to depend on achievement.
