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.

Why Nobody Understands Quantum Physics - Frank Verstraete and Céline Broeckaert **

It's with a heavy heart that I have to say that I could not get on with this book. The structure is all over the place, while the content veers from childish remarks to unexplained jargon. Frank Versraete is a highly regarded physicist and knows what he’s talking about - but unfortunately, physics professors are not always the best people to explain physics to a general audience and, possibly contributed to by this being a translation, I thought this book simply doesn’t work. A small issue is that there are few historical inaccuracies, but that’s often the case when scientists write history of science, and that’s not the main part of the book so I would have overlooked it. As an example, we are told that Newton's apple story originated with Voltaire. Yet Newton himself mentioned the apple story to William Stukeley in 1726. He may have made it up - but he certainly originated it, not Voltaire. We are also told that ‘Galileo discovered the counterintuitive law behind a swinging o...

How to Keep a Plane in the Sky - Alex Davies ****

If there's one big gap in the science writing sphere, it's popular engineering (you can quibble over whether engineering is science, but where else would you put popular engineering?). Alex Davies does the field a real service with this insightful introduction to the world of test engineering. The concept is simple. If we build something and sell it, we need to test it to make sure that it won't fail in a way that's dangerous to the consumer. The most obvious example is airliners, which feature at some length, but this applies to everything from cuddly toys to hair straighteners: someone needs to predict what could go wrong and to put the product through its paces to see if it will survive under any reasonable circumstances. When Davies is telling a story of test engineering in action, the book is a delight. He opens with the way that real bears are used to test if bears can get into coolers and trash cans - and the impressive ways these animals can  circumvent human in...

On the Equality of All Things - Carlo Rovelli ****

There is a wide gulf between the worldviews of physicists and philosophers. Many physicists present a rather sweetly naive, child-like view of the world, where philosophers bring a distinctly more adult, cynical tone. This being the case, it can be a little worrying when a physicist dips a toe into the philosophical mire. Infamously, in The Grand Design , Stephen Hawking and co-author Leonard Mlodinow told us that philosophy was now dead because science could deal with anything it had previously been needed for. Thankfully, Carlo Rovelli is not trying to do away with philosophy, though it has to be said that when he veers into the topic that physicist's naivety can make it feel like the philosophising of an earnest eighteen-year-old. Take the opening paragraph, which tells us 'electrons and minds, stones and laws, judgements and galaxies do not essentially differ in nature from one another. They are notions that illuminate each other'. I almost expected a Pink Floyd soundtr...
