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.

Religious life is about something real in human experience that is not constrained by what Wittgenstein called 'all that is the case'. In this sense Heidegger is not simply 'mistaken' - he just asks us, as philosophers mostly do, to think more carefully about what we're saying.

Perhaps unsurprisingly, there's a paradox here! Kierkegaard's own indirect communication proposes that we start with the experience of those who don't believe and meet them on their own ground. His success in doing this is evidenced by the fact that, at least for some periods of the 20th century, aspects of his work became a major focus for radical thinkers of various kinds, including the non-religious and, interestingly, a significant number of Jewish thinkers (Buber, Rosenzweig, Taubes, and others).

Perhaps - and this goes for the Kyoto School too - one of these insights is that nothingness and unknowing don't have to be equated with a destructive nihilism but with the experience of unity and participation - whilst resisting the tendency of objectifying metaphysics to claim that we can in some way 'know' that this experienced unity is really the truth of how things are, i.e., reveals being itself.

It's strange that in an age when we pride ourselves on our independence of thought we meekly submit without further question to the declaration of a clearly unbalanced nineteenth century philosopher that God is dead! That's cheeky, of course - and one rarely comes away from reading Nietzsche without learning something new and significant. He's certainly FAR more unsettling for faith than any contemporary atheist I know of.

Ethics arises in the recognition of our obligation to care for others as beings, like us, exposed to mortality - that is, beings who need our help. Buddhism, not wrongly, extends this to 'all sentient beings'.

What it does remind us is that 'God' is not to be separated from the quest for the Kingdom of God and is not and cannot be the object of any detached 'scientific' contemplation. Heidegger's critique of onto-theology is also driving a wedge between speaking of God and the aims of science - not so as to get rid of God but rather to free God from a false objectification.
