Why? - Philip Goff *****

It might seem a bit odd to review a popular philosophy book here, but Philip Goff's content overlaps sufficiently with cosmology that it's appropriate, and that content is fascinating, even though chances are you won't agree with Goff all the way.

The point of this book is to suggest that there is purpose behind the cosmos. The main evidence for this that Goff uses is the fine tuning of our universe that makes it suitable for life. Most cosmologists agree that this is odd, but many try to explain it using the idea of the multiverse. With some nifty mathematic-less probability (though he does invoke and describe Bayes theorem), Goff demonstrates convincingly that this argument does not hold up. (You can see some detail of how he shows that it's rubbish here.) 

We then take a look at a couple of alternative explanations - a deity, or the universe itself embodying a degree of purpose, which comes under the banner of panpsychism. I didn't honestly find the arguments in either of these sections (for and against) persuasive - but this doesn't stop them from being really interesting. In the God chapter, Goff attempts to logically dismiss the concept, but I found this no more convincing than good old Pascal's wager - people have been attempting to make logical arguments about deities ever since logic existed, and none have succeeded. 

Similarly, I find the argument for panpsychism thin - but it's still interesting to see it explained by one of its major protagonists. Goff also examines other possibilities from a designer that is not all-powerful to the simulation hypothesis. And he takes us into the mind-body problem, presenting three broad options: materialism (the default scientific view of the physical world being fundamental), panpsychism (his preferred option where consciousness is fundamental and the physical world emerges from this), and dualism (the default non-scientific view, where both the physical world and consciousness are fundamental). 

Goff rapidly dismisses dualism making use of Occam's razor, which felt wrong to me. The reality of our understanding of the universe generally requires a lot of 'it's more complicated than we thought' - I don't think Occam's razor is a good enough tool to dispose of an option in such a significant matter as the mind-body problem.

Finally (after a somewhat bizarre plea for the benefits of psychedelics, which I couldn't support), Goff gives us an appendix dealing with the concept that tax is theft. This did slightly emerge from the main text, but is probably best thought of as a separate entity - again, it's a fascinating exercise in thinking about something that brings together moral positions and a field as solid, worldly and sort-of scientific as economics.

It's a slim book and an enjoyable read. Each chapter has an introductory part that takes us into the topic and then a 'digging deeper' part, where Goff takes us through some of the key counter arguments. He suggests you can skip these if you find them too heavy going - but I'd strongly recommend reading them. I've said this book is enjoyable, and it is, but that doesn't mean it's a light read. You do have to think as you go - but the result is well worth the effort.

The Infinite Book – John D. Barrow ****

Authors are often asked to review books on a topic they’ve written on themselves. The reasoning is sensible – they ought to know something about the subject – but there’s always that uneasy suspicion that there’s going to be a bit of bias creeping in. So I think it’s only fair to admit up front that I have written a book on infinity (of which more later). Infinity is a wonderful subject, because it’s intimately mind-bending (if the combination sounds paradoxical, that’s what infinity is all about) and gives you the chance to pull in all sorts of different concepts and assocations along the way, something Barrow does with great gusto. There’s a surprisingly large amount of coverage here for God, and for the universe, and the book jumps around from Aristotle to Hilbert’s Infinite Hotel (explained at great length), from the paradoxes of infinite sets to the paradoxes of time travel. Overall it’s an enjoyable journey that gives plenty of opportunity to be amazed and surprised. The...

Adventures of a Computational Explorer - Stephen Wolfram ***

Stephen Wolfram, the man behind the scientist's mathematical tool of choice, Mathematica, plus a whole host of other software products, including the uncanny Wolfram Alpha knowledge engine, is undoubtedly a genius of the first order. In this book, we get an uncensored excursion into the mind of genius - which is, without doubt, a fascinating prospect. The book consists of a collection of essays and speeches that Wolfram has produced over the last ten to fifteen years, covering an eclectic range of topics. Like all such collections, the result is something that lacks the coherence of a book with a narrative that runs through it, inevitably introducing a degree of repetition and a mix of interesting and not-so-interesting topics - but there's likely to be something to catch the attention anyone who is into computing or mathematics. One of the most interesting pieces is the opening one, where Wolfram describes being a consultant on the SF movie Arrival. He seems to hav...

The Random Universe - Andrew Jaffe *****

This is an absolutely fascinating book for anyone interested in the way that science really works, bearing in mind the difficulties of having to base our models and theories on induction. Andrew Jaffe introduces the difficulties we face when trying to take a scientific view because largely we are dependent on induction: predicting the future from what has previously been observed. He explores what probability is, the two key ways of looking at it (frequentist and Bayesian) and how scientists use (or misuse it) to work out the implications of their experiments for hypotheses. This is then expanded into looking at the nature of scientific models and the philosophy of science before heading out to entropy, quantum randomness and attempting to achieve meaningful cosmology with its potential dearth of evidence.  The topic might sound a little dry, but in fact Jaffe does it with good humour and a very readable style. For example, he uses measuring his daughter's height by making marks on...
