There is something myopic and stunted in focussing only on the meaning of words and sentences. And this myopia is especially unfortunate when combined with a rather abstract view of a language as a set of elements and rules for combining these. For the result is to divorce enquiry into meaning from attention to the way words - and gestures, facial expressions, rituals and so on - are embedded in practices, in what Wittgenstein called 'the stream of life'.

To recognize that you are radically free, in Sartre's sense, but then to live as if you weren't, is to live in bad faith, in denial of what you know to be true. And that's not something anyone can sensibly want to do.

While I am happy to make the occasional foray into educational philosophy - writing, for example, of the difficulty in the contemporary context for a teacher to be 'truthful' - it is more the personal conduct of a life than social institutions that I am concerned to examine.

To describe this world is not to describe reality 'in itself', as it is independently of how we regard and describe it.

Things only 'show up' for us as they do, as Heidegger would put, in and through practical engagements with the world that enable objects to have significance and salience - as hammers, pots, trees or whatever.

I think it's true that for existentialist thinkers, appreciation of what we are - free, makers of meaning, 'issues' for ourselves, and so on - is at the same time a recognition of how we should try to live.

In the doctrine of the world and humankind as 'will to power and nothing else', Heidegger identified not an antidote to nihilism, but the completion of it. For what can be more destructive of truth and value than the doctrine that these are simply the impositions on the world of human exercises of power?
