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.

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).

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'.

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.

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.

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'.

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.
