Philip Goff - Five Way Interview

Philip Goff is Professor of Philosophy at Durham University. His research focuses on consciousness and the ultimate nature of reality. Goff is best known for defending panpsychism, the view that consciousness pervades the universe and is a fundamental feature of it. He is the author of  Why? the Purpose of the Universe (OUP, 2023).

Why philosophy?  

I love science, and try to stay as up to date as I can. But not every question can be answered with an experiment. Philosophy is about how all the different stories we tell about reality fit together. How does free will fit together with (near) deterministic physics? How do ‘right’ and ‘wrong’ fit with the value-less facts of science? How do invisible feeling and experiences mesh with the observable electro-chemical signalling of the brain? Experiments can inform our answers to these questions, but they can’t decisively settle them. 

Why this book?

So many people feel they have to fit into the dichotomy of either believing in the God of traditional Western religion or being a secular atheist. I was raised Catholic, but decided I didn’t believe in God when I was 14, and was happily on Team Secular for a long time. It wasn’t as though there was a God-shaped hole in my life, as far as I was aware. But over a long period of time, I came to think that both of these worldviews – the God hypothesis on the one hand, and the secular atheists belief in a purposeless universe on the other – were inadequate, both of them had things they can’t explain about reality. This led me to write this book defending cosmic purpose in the absence of the traditional God, and exploring its implications for human meaning and purpose.

Your demolition of the multiverse argument from fine tuning is impressive - why do you think we don’t see this argument cropping up in popular science?

I think it’s a typical case of academic talking to themselves. This objection to the inference from fine-tuning to a multiverse – that it commits the ‘inverse gambler’s fallacy’ – has been in the academic journals for decades. And yet nobody outside of academic philosophy knows about it, despite huge interest in this stuff. Moreover, believe it or not, nobody has ever linked this specific objection to the science of the multiverse, which is something I do in the book. So I’m really excited to get these ideas out to a broader audience. I’ve always thought fine-tuning needed explaining, and for a long time I thought the multiverse was the more plausible explanation. But I was slowly persuaded – dragging kicking and screaming, might be a better way of putting it – to these arguments from experts in probability theory that there’s some dodgy reasoning going on in the attempt to explain fine-tuning in terms of a multiverse. As a result I now think explaining fine-tuning has to involve cosmic purpose. That’s weird, and not how we expected science to turn out. But we should aside our cultural biases – both religious and secular – and just follow the evidence where it leads.

What’s next?

A rest. After that, I want to explore in more depth the under-explored challenge of how to make sense of the evolution of consciousness, which is one of the themes of the book. Natural selection just cares about behaviour, because it’s only behaviour that matters for survival. But recent developments in AI and robotics have revealed to us that you can have incredible complex information processing and behaviour in a system that doesn’t have any kind of conscious inner life. So why didn’t natural selection make survival mechanisms: complex biological robots that can mechanically track features of their environment and initiate complex survival behaviour, without being conscious? If we can’t answer that question, then we can’t explain why consciousness evolved at all.

What’s exciting you at the moment?

I’m excited to see scientists and philosophers coming together to make progress on these big questions. Science and philosophy need each other, especially when it comes to things like consciousness where no one really knows yet what the rules of the game are. In my previous book Galileo’s Error, I explored how the father of modern science Galileo put consciousness outside of the domain of science, to pave the way for mathematical physics. That worked really well for last four hundred years, because it gave scientists a focused, manageable project. But if we now want to bring consciousness back into the domain of science, if we want to answer the ‘Why?’ questions as well as the ‘How?’ questions, we need to find ways for scientists to work hand in glove.

Target Earth – Govert Schilling *****

I was biased in favour of this great little book even before I started to read it, simply because it’s so short. I’m sure that a lot of people who buy popular science books just want an overview and taster of a subject that’s brand new to them – and that’s likely to work best if the author keeps it short and to the point. Of course, you may want to dig deeper in areas that really interest you, but that’s what Google is for. That basic principle aside, I’m still in awe at how much substance Govert Schilling has managed to cram into this tiny book. It’s essentially about all the things (natural things, I mean, not UFOs or space junk) that can end up on Earth after coming down from outer space. That ranges from the microscopically small particles of cosmic dust that accumulate in our gutters, all the way up to the ten kilometre wide asteroid that wiped out the dinosaurs. Between these extremes are two topics that we’ve reviewed entire books about recently: meteorites ( The Meteorite Hunt...

The Decline and Fall of the Human Empire - Henry Gee ****

In his last book, Henry Gee impressed with his A (Very) Short History of Life on Earth - this time he zooms in on one very specific aspect of life on Earth - humans - and gives us not just a history, but a prediction of the future - our extinction. The book starts with an entertaining prologue, to an extent bemoaning our obsession with dinosaurs, a story that leads, inexorably towards extinction. This is a fate, Gee points out, that will occur for every species, including our own. We then cover three potential stages of the rise and fall of humanity (the book's title is purposely modelled on Gibbon) - Rise, Fall and Escape. Gee's speciality is palaeontology and in the first section he takes us back to explore as much as we can know from the extremely patchy fossil record of the origins of the human family, the genus Homo and the eventual dominance of Homo sapiens , pushing out any remaining members of other closely related species. As we move onto the Fall section, Gee gives ...

The New Lunar Society - David Mindell *****

David Mindell's take on learning lessons for the present from the eighteenth century Lunar Society could easily have been a dull academic tome, but instead it was a delight to read. Mindell splits the book into a series of short essay-like chapters which includes details of the characters involved in and impact of the Lunar Society, which effectively kick-started the Industrial Revolution, interwoven with an analysis of the decline of industry in modern twentieth and twenty-first century America, plus the potential for taking a Lunar Society approach to revitalise industry for the future. We see how a group of men (they were all men back then) based in the English Midlands (though with a strong Scottish contingent) brought together science, engineering and artisan skills in a way that made the Industrial Revolution and its (eventual) impact on improving the lot of the masses possible. Interlaced with this, Mindell shows us how 'industrial' has become something of a dirty wo...
