Members' Weekend 2020, Sat 15th – Sun 16th August

(Held online at a virtual Rewley House)

What is Life?

Links to talk recordings and transcripts will be added in the near future.

This year’s Members’ Weekend tackled one of the oldest problems in philosophy, that of saying what Life really is.

Life, as a natural phenomenon, is studied these days by scientists, who have been very successful at describing living things and living processes in impressive detail. And yet, despite this success, they remain unable to say what Life actually is. There’s no shortage of definitions – over a hundred, according to a recent study – with no single definition providing a clear distinction between things that are living and things that are not.
So, how might we distinguish Life from non-Life? What are the criteria by which we might decide whether something is alive or not alive? Is a virus a living thing? What about computer viruses? If they are living, are they alive in the same way that you are? What is it that makes living things alive? How will we recognise Life if we encounter it on other planets? Without a clear definition of “Life”, none of these questions is easily answered.
Over the course of the weekend, our speakers will address the question What is Life? from a range of different perspectives. This will be followed by a Panel Discussion, where you can put your questions to each speaker, and maybe tell us what you think Life is.

Mike kicks off our discussions by asking what it is we have in our mind when we use the word “Life”, and hence when we ask the question: What is Life? Is it limited to the sort of Life we are familiar with here on earth – cell-based, Carbon-based, DNA-based, etc. - or do we have a broader concept of what Life can amount to – a concept which allows Mr Spock to utter those immortal words: “It’s Life Jim, but not as we know it.” By examining our human conception of Life, Mike sets out to find what key characteristics we look for when we distinguish in our minds between Life and non-Life.
Mike Arnautov is from Prague where he studied mathematics and physics, followed by an MSc in statistics. He came to England in 1970 and was awarded a PhD by Bristol University for research in Artificial Intelligence. He then spent 30 years as a systems programmer / architect in a research environment, supporting biologists, geneticists and bioinformaticians. In his spare time, he reads a lot of science fiction, which is how he got interested in AI. Mike considers all these strands important in shaping his views on life, the universe and everything.

The biological world, ranging from viruses and bacteria to Homo sapiens, is examined and classified by the biological sciences. The man-made world, with all our society, machines, buildings and culture, lies outside of this classification and is examined through other disciplines, e.g. social sciences, history or politics. And yet Nations share many of the same key characteristics we find within living organisms. Gordon examines these characteristics and proposes a new four-level structure for classifying living things.
Gordon Nichols is a scientist who has worked as a Consultant Epidemiologist within Public Health England. He has contributed to research projects on gastrointestinal infections, food, water and the environment, epidemiology, public health and climate change and has been important in surveillance and outbreak management. He has contributions to international initiatives and has given over 400 scientific presentations, written 31 book chapters and 78 papers in peer reviewed journals.

Life, it may seem reasonable to suppose, is an emergent property of matter, which appeared by chance four billion years ago via a yet-to-be-understood process we call abiogenesis. And yet, the idea of Life as an emergent property brings with it a number of problems. What does this so-called ‘emergence’ amount to? How did all the biological capabilities required for Life emerge at the same time? And could this really have happened by chance? But perhaps the biggest challenge for this emergence view of Life, Jeff argues, is that, in order for it to be true, you need to show that God does not exist.
Jeff Morris is an Oxford Trinity 2019 student essay prize winner who has studied metaphysics, logic, and epistemology. He has published a half a dozen popular level articles, and a short philosophical novel entitled, A Moment in Time. He is currently enrolled in graduate studies at Tyndale, one of Canada’s leading theological Universities.

In 1944, Erwin Schrödinger addressed the question What his Life? from a physicist’s perspective, noting the ability of living things to defy the Second Law of Thermodynamics and maintain their bodies far from equilibrium with their environment. In the process, he anticipated the discovery of the aperiodic crystal we call DNA. Seventy years later, Addy Pross addressed the same question, this time from the perspective of a chemist, describing how autocatalytic, replicating chemistry is able to outsmart the Second Law. Tomy and Stewart look at what lessons we can learn from Schrodinger and from Pross.
Stewart Fisher is a retired consultant respiratory physician, an amateur biologist, a lepidopterist and until recently a biological field guide in Central Africa. He collaborated with biologist Brian Goodwin looking at fractal geometry in biological organisms.Tomy Duby, born in Bratislava, is a retired experimental physicist who spent his working life designing superconducting magnets for medical purposes. Since forced retirement five years ago he and Stewart have almost daily sessions where they read books, mostly on philosophy, covering a range of topics from Harold Bloom to Karl Popper. They approach this topic from diametrically opposed perspectives.

Starting with the Big Bang, Martin describes the principal changes that enable matter to behave in the way we call Life. He argues that there was no spark or moment when Life began, but rather a continuous process of increasing complexity, which depends on a flow of information through time. Our minds are ill-suited to understanding this continuum, because they build models with well-defined boundaries, and seek to fit our perceptions to them. However, they do provide a habitat for ideas which compete for our conscious attention and, in so doing, themselves fit this understanding of Life.
Martin Jacoby is a life-long naturalist. After reading zoology at Oxford, he taught in schools before going to live in Spain. There, and later in South America, Africa, Caucasian Georgia and elsewhere, he explained to holiday-makers the human impact on wildlife. Personally witnessing desertification and the global collapse of biodiversity, Martin enquired into the human condition, especially the origins of our drive to convert the beautiful places of the Earth into human waste.

4.50 Autopoiesis and the Complexity of LifeBob Clarke

Autopoiesis was conceived in the 1970’s with Maturana and Varela’s description of living things as autopoietic machines – self-producing networks of processes, which constantly regenerate the components from which they are made. Since then, autopoiesis has developed into a much broader understanding of Life, involving a range of concepts, including Cognition, Emergence, Embodiment, Enaction and Embeddedness, providing both a Bottom-Up and a Top-Down view of Life. Bob provides an overview of the field, and explains why a simple answer to the question What is Life? may not be feasible.
Bob Clarke studied Physics at Bristol University in the late 1960s and has since followed a career in Physics and Microwave Engineering – he is still working part-time in this area. He acquired an interest in Philosophy and History of Ideas in the early 1980s and subsequently obtained a BA in History of Ideas from Kingston University in 1994 and an MA in History of Ideas from Birkbeck College in 2010. Bob is a judge for The Philosophical Society’s Student Essay Prizes and occasionally gives talks to amateur philosophy groups.

“The idea of ‘objective reality’ […] undergoes important modifications when it is to be understood, not in relation to the ‘world described by science’, but in relation to the progressing life of a person.” (Iris Murdoch, The Sovereignty of Good)
In our penultimate talk, Fauzia argues that scientific attempts to answer the question ‘What is Life?’ fall foul of several fallacies. Nonetheless, the question is philosophically interesting because of what these attempts show us about human agency and imagination. She concludes with arguably the most pressing and “real” of all questions: not the question ‘What is Life?’ but rather ‘How ought we to live?’
Fauzia Rahman-Greasley is a retired medical practitioner (qualified from St Barts, London) with an MA in Philosophy (from Birkbeck, London). She is a former chairman of The Philosophical Society (2015-18), Editor of the Review (2018-19), and is course director and regular lecturer of the Gerrards Cross Philosophy group. She is author of the farce, ‘The Philosopher’s Tale’, which premiered in Covent Garden in 2013.

11.55 Biogenesis: All Life comes from LifeTim Bollands

Slides (PDF format)
Tim wraps up the weekend by drawing lessons from all seven talks so far, in his attempt to develop a definition for Life that draws a clear and unambiguous distinction between living and non-living things. In doing this, he suggests that any successful definition will necessarily be circular, but that there’s a reason for this. All Life, as Thomas Huxley said, comes from Life – a proposition known as biogenesis and supported by all available evidence. The problem is: biogenesis doesn’t fit with our current scientific understanding of the world. Therefore, for it to be true, our current scientific worldview must be false.
Tim Bollands studied mathematical physics at Oxford, and spent the next 30 years or so as a management consultant, helping large organisations gain greater value from their IT systems. He never lost his desire to make sense of the universe, however, and since the age of 25 has been struggling to write his ‘magnum opus’, in which all the great problems of physics and natural philosophy would finally be solved. On turning 50, he put his career on hold, started writing in earnest and has recently finished his first book: Life, the Universe and Consciousness.
