I'm not sure if Cupitt himself still uses this term, but it's useful in suggesting that, actually, there are more choices than the choice between nihilism and faith. In fact, the issue may not be faith as such but the fact that for millennia, Christianity has buttressed itself with a particular kind of metaphysics that has now seemingly reached the end of its life-span. But perhaps Buddhist metaphysics could provide an alternative here - or, at least, offer a direction of travel.

But, inevitably, as he [Kierkegaard] approaches what we might call his Christocentric climax many readers drop off. Many scholars just leave that part of his authorship alone.

But why should a religious person be interested in a work like Heidegger's that many regard as the epitome of nihilism? For a start, because Heidegger forces us in a way that few philosophers do to really think through the seriousness and all-encompassing nature of our mortality.

Perhaps this is an area where every generation starts from scratch. Although the crisis of the First World War inaugurated an especially strong period of disillusion with regard to the optimism of the previous age, the pattern has repeated itself in many ways in more recent times, e.g., the loss of faith in politics as a means of advancing human well-being. And perhaps this also has to do with basic elements in growing up.

And perhaps this has to do with what I sense is a turning away from the idea of religion as being about conserving a certain heritage from the past towards religion as having to do with how we orientate ourselves to the future, to all we truly long for, to hope.

When I'm on the operating table, I'm happy for the surgeon to treat me as a machine, but the moment I return to consciousness I have other needs and aspirations that should be recognized. We're not here only to survive or extend our individual or species life but to do something seemingly more difficult, for which I've used words and phrases like 'love' and the 'Kingdom of God'.

And one thing the void certainly can teach us is how to wait, how to become truly patient, and how to let go of superfluous intellectual baggage - all of which is a good lesson for hyper-agitated multi-tasking goal-focussed contemporary human beings.
