INTRO: Once ridiculed, panpsychism – the idea that all matter has some degree of consciousness – has gone mainstream. Philip Goff, one of the main defenders of panpsychism, now turns his attention towards another taboo question: does the universe as a whole have a purpose? In this interview, Ricky Williamson asks Goff how to make sense of fine-tuning, and what role psychedelics and mystical experience might have in coming to view the universe as a conscious mind.
EXCERPT: [...] In your upcoming book 'Why?: The Purpose of the Universe', you argue that the universe has a purpose, and it seems a lot rides on your ideas around cosmological fine-tuning. If the strength of gravity was slightly different, or the mass of an electron, life could not have arisen in our universe - it appears to us then the universe is fine-tuned for life. I think most people dismissed the problem of cosmological fine-tuning when they dismissed the idea of God. Why the focus on fine-tuning? And why is fine-tuning not explained by the idea of a multiverse, where you'd expect one of many (many) multiverses to be able to support life?
Humans always think they’re at the end of history. Before the scientific revolution in the 16th century, people thought Aristotle had basically got everything sorted, including that the Earth was in the centre of the universe. They thought they had it all figured out! And as the evidence against this Earth-centred model of the universe began to mount, people struggled to accept that this version of reality no longer explained the data.
Today, popular science programs regularly scoff at our ancestors’ foolish inability to follow the evidence where it leads. But every generation absorbs a worldview they struggle to see beyond. I believe we’re in the same situation now with respect to fine-tuning. People are ignoring the evidential implications because it doesn’t fit with the picture of the universe we’ve got used to.
I used to go for the multiverse explanation myself. But I became convinced by philosophers of probability that the attempt to explain fine-tuning in terms of a multiverse commits the ‘inverse gambler’s fallacy.’
Suppose you and I go to a casino tonight, and the first person we see is some guy having an incredible run of luck, winning time after time. I turn to you and say, ‘Wow, there must be lots of people playing in the casino tonight.’ Naturally you’re baffled by my comment and request clarification on how I reached that conclusion, to which I reply, ‘Well, if there were few people in the casino, it’d be highly improbable that someone in the casino would have an incredible run of luck. But if there are a huge number of people in the casino, it’s not so improbable that, by chance, someone would win big.’
Now, everyone agrees that this is a fallacious inference: We’ve only observed this one guy, and the number of people elsewhere in the casino has no bearing on whether the one guy we’ve observed will roll well. I think the multiverse theorist is making exactly the same flawed inference. All we’ve observed is this one universe. And whether or not there are other universes out there has no bearing on whether the one universe we’ve observed is fine-tuned... (MORE - missing details)
