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.

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'.

Every stroke a tennis player plays is different, yet we perceive them as playing in a distinctive and unique way. It's what Heidegger called a certain 'how' of existing. It's ultimately always singular, and the double task of (a) getting it in view and (b) communicating it to others will inevitably be marked more often by failure than success!

I'm not sure how far Derrida's later 'theological' interests are really rooted in post-structuralism or whether they don't rather reflect a kind of Kantian-Marxist trajectory - with a French twist on the centrality of liberty, equality and fraternity (cf. Politics of Friendship). Not to mention the role of Levinas and, behind Levinas, Judaism's twinning of eschatology and the call for justice.

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.

In brief, I regard love as a more decisive focus of meaning than death. In terms of Heidegger's argument, this is because I think he misdescribes the importance of the deaths of others and focuses exclusively on my relation to my own death. But, in reality, the deaths of others have a more urgent and immediate impact on our lives than the purely notional knowledge that I too will one day die.

Now, as at the beginning of the 19th century, there is a certain discovery of Eckhart and related figures. There are questions as to how far our Eckhart accords with the real medieval teacher of that name, but there are certainly images in his work that help us work our way past several of the aporia with which we're confronted in our attempts to think about God.
