I know I often write about philosophy books on this blog, as it's a big hobby for me. But don't anybody get the idea that I'm breezing through these books. Mind and the World Order is not light reading; it dives more or less immediately into such issues as (for example) whether the universe has some special character or structure that makes it susceptible to interpretation and categorization by the mind, or if, instead, our shared categories are merely "the combined result of the similarity of human animals, and of their primal interests, and the similarities of the experience with which they have to deal." So I have to carefully read and re-read each paragraph, often several times, to understand what is being said and follow the long chains of argument that logicians like Lewis revel in. The only thing I can compare it to is reading a computer program.
So what have I learned about the structure of the universe now that I'm 45 pages into the book? Well, Lewis seems to be saying that the possibility of knowledge does not require us to believe that the fabric of reality itself is somehow uniquely in tune with the interpretive apparatus of the mind. (Compare this with Wittgenstein's "The world divides into facts.")
Lewis is from my own home state of Massachusetts, which may be why I find him a bit easier to read than Wittgenstein. I can read the latter only in translation (not to mention his utterly flat and succinct-as-a-machine-gun writing style.)
