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.

There are kinds of unity other than those of the explicit and systematic unity that Poole is attacking. There are kinds of movement - in music or athletics, for example - that present themselves as having a certain unity about them. In some sphere we might talk about 'style'.

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.

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.

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.

Interpretation is a task that we repeatedly have to take up and start again from the beginning, Sisyphus-like. But, as Camus said, we must always imagine Sisyphus happy, and this is not so difficult when it's a matter of texts that reveal important truths about being human.

In a sense these are questions that most people ask themselves to some extent. They become philosophical when asked with a persistence and rigour that pushes past conventional or evasive answers. It's nothing to do with acquiring a technical facility in an academic discipline.
