For all her active goodness, Florence Nightingale herself was far from being the angelic figure of popular adulation: according to Lytton Strachey's Eminent Victorians she was a self-righteous, domineering amazon, who was ruthless in her compassion, merciless in her philantropy, destructive in friendships, obsessional in her list for power, and demonic in her saintliness.

Scandal, it bears repeating, undermines monarchies, but rarely ends them. It may be true that, according to a recent editorial in the New York Times, the British monarchy now exists primarily 'for our amusement'. But as long as people find it amusing, and want to be amused by it, they will be happy to see it undermined but uneager to kill it off.

Royal relationships across the generations have often been strained and distant, rather than close and affectionate. Most eldest sons, interminably waiting to become king, have not been on the best of terms with the sovereign to whose death they look forward with a debilitating combination of guilt-ridden anxiety and eager anticipation. And younger sons (and daughters, too) have often found their lives empty of purpose: cut off by their royal statius, but unable to find anything rewarding with which to fill the time.

David Irving has consistenly applied an evidential double standard, demanding absolute documentary proof to convict the Germans (as when he sought to show that Hitler was not responsible for the Holocaust), while relying on circumstantial evidence to condemn the British (as in his account of the Allied bombing of Dresden).

Prince Charles's concern for the underprivileged and disadvantaged has not exactly endeared him to the Conservative Central Office. As Norman Tebbit replied, it is not surprising that the Prince is so sympathetic towards the unemployed: he is by way of being one of them himself.

Of all the memorable phrases that have been minted and mobilised to describe modern British royalty, 'constitutional monarchy' is virtually the only one which seemes to have neither been anticipated nor invented by Walter Bagehot. It was he who insisted that 'a princely marriage is the brilliant edition of a universal fact, and as such it rivets mankind'; and he who warned that the monarchy's 'mystery is its life. We must not let in daylight upon magic'.

Charitable endeavour exalts the prestige and the status of the giver. This may sound unduly cynical but as with all philantrophic activity, it is not easy to unravel the mutually reinforcing motives of selflessness and self-interest. All that can safely be said is that most members of the royal family have difficulty distinguishing between concern about society, concern about the social order and concern about what best to do so they can remain at the top of it.
