Thesis
So here's the thesis (PDF, 250 pages, 1.7 MB and in German). I'm a little dissatisfied with the presentation: it shows that it was finished in a hurry. I will do some polishing before the obligatory publication, and I'd recommend not reading it through in its current state.
For the most part, the book is an overview of Lewis's philosophy, with an emphasis on metaphysics. I discuss Lewis's views on non-present times and non-actual worlds, on mathematics and properties, his physicalism and Humean Supervenience, and the basic framework of his philosophy of language. One aim of this is to ease the understanding of Lewis's positions by tracing out all the interconnections between his theories. More importantly, I try to show how the package can be broken up: that one can, for example, accept most of what Lewis says about language and laws of nature without accepting his modal realism and his doctrine of objective naturalness. There's also a rather lengthy discussion about methodology and the relationship between modal/metaphyical and analytical reduction.
I've posted most of the interesting bits in this weblog here while I was working on them, and I'll probably write two or three small papers (in English) about some of it in the coming months.
many thanks for making that available. I flipped through it - decent reading has to wait until I manage to print it -; what first comes to mind: Think of publishing this as a book, it seems to be laid back and clear, not the fury of thought and "formulae" one finds sometimes in this part of the woods.
Congratulations and all that
M.
