In his 1886 preface to the second edition of The Gay Science, Nietzsche speaks of the gratitude of the convalescent and by which he refers to the rejoicing of one who has resisted a terrible ordeal or period of sickness without complaint, without submission, and, crucially, without hope.
I have to say, I find this idea - an old Norse idea - very attractive this Christmas; the refusal not only to give in or give up, but to accept the consolation of any teaching that promises a better time to come. It's easy - or at any rate, easier - to endure great hardship or pain if you believe that tomorrow will bring relief or even some form of reward (if not in this life, then in the next).
It takes a more cheerful form of bravery and a more philosophical bent, to abandon all hope and put aside all trust in those ideals and sentimental illusions in which we may have formerly found our virtue and our humanity.
For Nietzsche, we are born into what he terms the greater health when we realise that it is often sickness, suffering and, indeed, wretched failure, which best liberate the spirit; that is to say, it is pain and loss that make us not exactly better souls, but almost certainly more profound thinkers.
Of course, it's true that such a pessimistic teaching means that one is no longer able to trust in life and life's goodness - that life itself becomes problematic (becomes a question of evil). Yet one should not assume that this makes gloomy or unable to love; on the contrary, love remains possible, but one must love differently "with a more delicate taste for joy".
At the bottom of Pandora's box lies the unopened gift of hope - it can stay there!
