The world's response to the death of Nelson Mandela is a richly deserved recognition of the suffering and struggle he endured in defence of his principles, and the humility and magnanimity he showed when he finally achieved his, and his people's, freedom.
He didn't just proclaim his belief in human dignity and his insistence that we are all equal in our humanity - he lived it. It is this shining example, this living embodiment of the quest for freedom and justice, that has touched so many people.
Nelson Mandela at least had the satisfaction of living long enough to see his life's work vindicated, even by many of those who opposed him. It is a safe bet that a substantial proportion of those world leaders who paid him homage at yesterday's memorial service would not have given him the time of day when he was incarcerated on Robben Island; some, we are told, "can't remember" what they thought of him at that time and others condemned him as a terrorist. The prospect of the presence of such people at his memorial service was an irony that was not, it seems, lost on Mandela himself.
But history is full of examples of brave men and women who stood against the prevailing tide in order to stay true to the ideals of freedom, social justice and human dignity but, unlike Mandela, went to (or were sent to) their graves without ever seeing the fruits of their efforts. For many, it was only in death that their true worth, and the rightness of what they fought for, was recognised.
Mandela was, in this as in so many other respects, an exception to the rule. While he himself was the first to recognise that his eventual triumph did not mean that South Africa became overnight the promised land (in economic terms at least), the outpouring of gratitude for what he had achieved shows how much the freedom from repression and injustice has meant to the people whose interests he served so faithfully. He was left in no doubt that freedom and justice - and the chance of a better life - mattered greatly to those who had been denied them.
