Quotes

• MORAL REALITY AND MORAL FACTS -- https://www.whyarewehere.tv/people/george-ellis/
  • Now what you have to do there is then say, well, what is the nature of the moral reality? And you then have to realise that the simplistic views of morality are not correct. Real morality is not a set of ten laws on a tablet which you can write down, because those are a terrible approximation to the real thing, and from my viewpoint, the deep nature of reality, which is discovered by the spiritual members of all the great traditions in the world, is that the deep nature of morality is to do with self-sacrifice and giving up on behalf of other people. It’s counter-intuitive. It’s not a logical argument, and people are looking for logical laws that they can apply. But the deep nature of morality, from my position, is that it is the counter-intuitive thing: that if you want to get something, and create greater good, you must give up, and the way to getting what you want is giving up what you want, and that’s the way to get what you want.
  • The religious literature has known this for thousands of years: the fact you feel good about something doesn’t mean that it is the good thing to do. Good and evil is not scientifically measurable and so it’s not a scientific concept.
  • My definition of a fundamentalist is someone who takes a partial truth and claims it’s the total truth, and that’s exactly the problem here.
• WHAT IS FINE-TUNING? -- https://www.whyarewehere.tv/people/george-ellis/
  • Fine-tuning is a philosophical problem. It’s not a scientific problem in the sense that there’s an experiment which gives a result. The problem is that some of my colleagues are writing about it as if it can be solved on a purely scientific basis, and I think this is very misleading to the public, and I think it’s very misleading within the scientific community. I think it’s a problem when scientists present a philosophical statement and claim it can be tested or proved scientifically.
• TOP-DOWN CAUSATION -- https://www.whyarewehere.tv/people/george-ellis/
  • Yes, I take the completely unpopular position: I’m a dualist. There’s the mind and the brain, and the mind inhabits the brain… or thoughts, thoughts inhabit the brain and thoughts are not physical things. Thoughts are abstract things which get represented in a physical way. And again we do not understand how this happened, but the brain has a hierarchical structure. Thoughts have a hierarchical structure, and in the computer you can see these different levels. You can understand them, and you have got these interpreters or compilers which do it. I think eventually when we understand the brain enough, we will see exactly the same kind of structure happening in the brain. The logic is going top-down from the top level down to the bottom and it is the logic which is controlling what happens at the bottom level. Abstract entities are driving the physics at the bottom level. The physics is not controlling what happens.
• THE ETERNAL TRUTHS OF MATHEMATICS -- https://www.whyarewehere.tv/people/george-ellis/
  • Yeah, but physicists have great trouble telling you this famous question. Why does mathematics underlie physics? The famous thing that Galileo said that the nature of the universe is written in mathematics. And Wigner and Penrose and other people have pondered, why is it that physics can be written in mathematical terms? And that’s a deep philosophical question for which we don’t have a proper answer.
• "On the limits of quantum theory: Contextuality and the quantum–classical cut", Annals of Physics 327 (2012) 1890–1932
  • The basic viewpoint taken here is that physical theory must explain not only what happens in carefully controlled laboratory experiments, but also the commonplace features of life around us, for which we have a huge amount of evidence in our daily lives.

Importance of philosophy -- https://blogs.scientificamerican.com/cross-check/physicist-george-ellis-knocks-physicists-for-knocking-philosophy-falsification-free-will/

• Above all he believes that these mathematically based speculations solve thousand year old philosophical conundrums, without seriously engaging those philosophical issues. The belief that all of reality can be fully comprehended in terms of physics and the equations of physics is a fantasy.
• You cannot do physics or cosmology without an assumed philosophical basis. You can choose not to think about that basis: it will still be there as an unexamined foundation of what you do.
• Attempts to explain values in terms of neuroscience or evolutionary theory in fact have nothing whatever to say about what is good or bad. That is a philosophical or religious question (scientists trying to explain ethics from these kinds of approaches always surreptitiously introduce some unexamined concept of what is a good life by the back door).
• Actually philosophical speculations have led to a great deal of good science. Einstein’s musings on Mach’s principle played a key role in developing general relativity. Einstein’s debate with Bohr and the EPR paper have led to a great of deal of good physics testing the foundations of quantum physics. My own examination of the Copernican principle in cosmology has led to exploration of some great observational tests of spatial homogeneity that have turned an untested philosophical assumption into a testable – and indeed tested - scientific hypothesis. That’ s good science.
