AS I write this, Nelson Mandela is still with us. But this is his fourth hospitalisation in six months and the prognosis for 94-year-old men with persistent lung infections is not good. How will South Africa do without him?
In practice, South Africa has been doing without the man for more than a decade - but psychologically, it is just now getting to grips with the reality that he will soon be gone entirely.
For all its many faults and failures, post-apartheid South Africa is a miracle. Although Mandela left the presidency in 1999, he is still seen as the man who made the magic work, and somehow the guarantor that it will go on working. If only in some vague and formless way, many people fear his death will remove that safety net.
Just in the past two weeks, however, the tone of the discussion has begun to change. On hearing Mandela was in hospital again, Andrew Mlangeni, one of his dearest friends and once a fellow prisoner on Robben Island, said: "It's time to let him go. The family must release him, so that God may have his own way with him."
That comment had a strong resonance in traditional African culture, which holds that a very sick person cannot die until his family "releases" him. They have to give him "permission" to die, by reassuring him that his loved ones will be fine when he's gone. So South Africans must now accept that they can get along without Mandela, and then he will be free to go.
