In my last essay, I decided that I understood ancient Platonism. In this post, though, I will not pretend to understand modern physics. I will, however, say some things about a recent book from an eminent theoretical physicist and cosmologist, Lee Smolin (who also happens to be my uncle), that I recently read: Time Reborn: From the Crisis in Physics to the Future of the Universe.
Many of my posts on here are notable for their sheer cheek in tackling topics, but this one, as they say, takes the cake. If you happen to know about this topic, then please accept this humble disclaimer that I emphatically not a physicist, and take this as what it is: some hopefully interesting comments from a non-expert.
What is the Trouble?
Lee Smolin's task over the last decade or so has been to argue that (1) modern physics and cosmology has reached a crisis point that threatens the bases of the entire field, and (2) only a radical paradigm shift can save it. The former point was argued at most length in his previous book The Trouble with Physics, while Time Reborn attempts to provide a way forward and a sketch of the necessary paradigm shift: an effort that he has more recently followed up on with several other volumes along the same lines.
This, I think, is the best sort of book to gain some measure of understanding of a field: not a textbook or popularization, both of which typically present caricatured versions of research from decades ago without interpretation or explanation, but a interpretation of a field by an acknowledged master with a clear and obvious angle.
Of course, such interpretation of a whole field, especially a field as abstract and analytical as theoretical cosmology, cannot help but be philosophy.
I won't defend this claim, which would drive many physicists crazy, but I will, as stated above, comment on the book's conclusions and arguments from the perspective of someone well-versed in ancient and medieval philosophy.
