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'.

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.

Ultimately, we live in the face of an irresolvable mystery about our origin and, for that matter, about our end. And what Schleiermacher would have us do is (a) acknowledge that this is the case and (b) accept it as something positive, a point of departure for a life of trusting joy.

Of course, it's always difficult to disentangle fact from fiction in relation to, e.g., the singularity project. Many scientists I know are dismissive of transhumanist claims, BUT the last 100 years has surely taught us never to underestimate the pace and scope of scientific progress. However, even if much of this turns out to be science-fiction, it also reveals a way of thinking about human life that I find deeply troubling.

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.

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.

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'.
