Here is the power point file of the lecture I just gave at the World Congress of Philosophy in Beijing.
In his Tractatus Wittgenstein speaks both of the world and of descriptions of the world. I argue that his use of that second term derives from its occurrence in Alexander von Humboldt's "Kosmos".
My project is simple but demanding. I am trying to reread Wittgenstein from the beginning without, however, relying on any established interpretations. My question is whether we can look at his work with fresh eyes. Ignoring the halo of secondary writing that now surrounds that work does not mean that I will always end up disagreeing with what previous interpreters have said. But my plan is to re-discover their insights where they are such and otherwise go my own way.
In doing this, I want to look more thoroughly at Wittgenstein’s own words than has previously been done. I don’t know how far I will get with this but completeness is not my goal. It is rather to start with the first sentence of the Tractatus and work myself forward from there as far as I can manage.
On the gravestone of the poet Rainer Maria Rilke we can read one of his last poems which says: Oh rose, you pure contradiction. To be nobody's sleep under so many eyelids." Is there a self and if not, who am I?
“In what sense are my sensations private? – Well, only I know whether I am really in pain; another person can only surmise it. – In one way this is wrong, and in another nonsense. If we are using the word ‘to know’ as it is normally used (and how else are we to use it?), then other people often know when I am in pain. – Yes, but all the same not with the certainty with which I know it myself! – It can’t be said of me at all (except perhaps as a joke) that I know I am in pain. What is it supposed to mean – except perhaps that I am in pain.”
Ludwig Wittgenstein was one of the leading philosophical minds of the twentieth century and his thought remains of live interest. Twenty years ago, David Stern and I published the Cambridge Companion to Wittgenstein which was intended to help readers of Wittgenstein along. We have now brought out a second edition of this work with some great new contributions and a completely updated bibliography.
