Panpsychism and Moral Status

Panpsychism is the view that sentience is ubiquitous in the world. Some people find it attractive because it sidesteps the challenge for dualists of explaining why there are two radically different types of things in the world, physical things and mental things.  And panpsychism seems to avoid some of of the challenges that face physicalist accounts of consciousness of explaining how mental properties are related to physical properties; since pan-psychism says that “mentality” is everywhere, the task left for cognitive scientists is simply to explain why that mentality is organized in a particular way rather than needing to directly address the “hard problem of consciousness'” head on.

Many people also find sentientism, the view that sentience is sufficient for moral status, attractive.  So it can be tempting to combine panpsychism and sentientism and conclude that we can assume that all animals, including oysters, snails, and fruit flies, must necessarily have moral status.  This move is a mistake.

The problem with the above move is that it rests on an equivocation on the term “sentient.”  One definition of sentient means “the ability to feel pleasure and pain.”  Another definition means “the ability to have any types of conscious experiences.”  The link to moral status requires the first definition of sentience.  But panpsychism, if true, only entails the second.

Beyond just the definitions, it certainly seems like there are a lot of experiences that are neither positive nor negative…they are simply neutral.  So the fact that some experiences occurred doesn’t tell us that anything morally significant occurred in the absence of further knowledge about what types of experiences they were, even for a sentientist.

But what about observing avoidance behaviour?  If we see that, and we think that mentality is everywhere, shouldn’t we conclude that the avoidance behaviour is indicative of suffering?  But this seems contrary to what we know about pain.  People can still have withdrawal reactions that rely on spinal reflexes, even when they self-report that they don’t feel pain.  In fact, in rare cases, people even report feeling pains but not finding them unpleasant.

So panpsychism doesn’t really sidestep the challenge of determining which types of behaviours in nonverbal populations are indicative of positive or negative experiences.  They may avoid having to take on the hard problem of consciousness but they are left with the hard problem of morally relevant consciousness.

Japan to Allow Human-Animal Hybrids to be Brought to Term

By Mackenzie Graham

The article was originally published at the Conversation

Around the world thousands of people are on organ donor waiting lists. While some of those people will receive the organ transplants they need in time, the sad reality is that many will die waiting. But controversial new research may provide a way to address this crisis.

Japan has recently overturned its ban on the creation of human-animal hybrids, or “chimeras”, and approved a request by researchers from the University of Tokyo to create a human-mouse hybrid.

Scientists will attempt to grow a human pancreas inside a mouse, using a certain kind of stem cell known as “induced pluripotent stem cells”. These are cells that can grow into almost any kind of cell. The stem cells will be injected into a mouse embryo, which has been genetically modified to be incapable of producing a pancreas using its own cells. This hybrid embryo is then implanted in a mouse surrogate and allowed to grow. The goal is to eventually grow a human pancreas in a larger animal – such as a pig – which can be transplanted into a human.

Researchers have grown groups of brain cells in the lab –
known as ‘organoids’ – that produce brain waves resembling
those found in premature infants.

Scientists have become increasingly adept at creating brain organoids – which are essentially miniature human brains grown in the laboratory from stem cells.

Although brain organoid research might seem outlandish, it serves an important moral purpose. Among other benefits, it promises to help us understand early brain development and neurodevelopmental disorders such as microcephaly, autism and schizophrenia.

YouTube interview: Shelly Kagan on Animal Ethics

Should we increase the cognitive capacities of fish if we can? If we enhanced a chimpanzee so that it had the same cognitive capacities as us, would it have exactly the same moral status as us? Is it morally preferable to kill a mouse or to destroy a robot? Could there be beings with a higher moral status than us? These are some of the questions Professor Shelly Kagan (Yale) answers in this interview with Katrien Devolder (Oxford) (Professor Kagan delivered the 2016 Uehiro Lectures on animal ethics at the University of Oxford. The Audio files of these lectures can be downloaded at http://www.practicalethics.ox.ac.uk/l….)

Organ Mules

Julian Savulescu

While politicians wring their hands about sensible solutions to the organ shortage, scientists are progressing with genetic manipulations that may see human organs grown in pigs.

US scientists are creating novel life forms: “human pig chimeras”. These are a blend of human and pig characteristics. They are like mules who will provide organs to us. A mule is the offspring of a male donkey (jack) and a female horse (mare). Horses and donkeys are different species, with different numbers of chromosomes but they can breed together.

In this case, they take a skin cell from a person and turn it back in time to make stem cells capable of producing any cell or tissue in the body, “induced pluripotent stem cells.” They then inject this into a pig embryo. This makes a pig human chimera.

However they do a modification to the pig embryo first. They use gene editing, or CRISPR, to knock out the pig’s genes which produce an organ, say the pancreas. The human stem cells for the pancreas then make an almost entirely human pancreas in the pig human chimera. It functions like an organ mule. (The blood vessels are still porcine.)

In this way, your skin cell could grow a new liver, heart, pancreas, or lung.

This is a technique with wider possibilities: other US teams are working on a chimera –based treatment, this time for Parkinson’s disease which will use chimeras to create human neurones.

CRISPR is also credited with enhancing the safety of this technique, with the BBC reporting  that a Harvard team were able to use the new and revolutionary technique to remove copies of a pig retrovirus.

Safety is always a major concern when science crosses new boundaries. But even if a sufficient guarantee of safety could be reached, are there ethical problems?

The Moral Significance of Animal Suffering

Recently I attended a fascinating Society for Applied Philosophy lecture by Shelly Kagan, entitled ‘What’s Wrong with Speciesism?’. Kagan began the lecture by explaining how, while teaching a course involving some of Peter Singer’s writings on non-human animals, he had begun to doubt the view, defended by Singer, that other things equal the suffering of animals matters no less than that of human beings.

New Book: The Ethics of Embryonic Stem Cell Research

There is wide agreement that embryonic stem cell research holds unique promise for developing therapies for currently incurable diseases and conditions, and for important biomedical research. However, as it is currently done, the isolation of embryonic stem cells involves a process in which an early embryo is destroyed, which many find highly problematic.

This has resulted in what I refer to in my book as

The Problem. Either one supports embryonic stem cell research and accepts resulting embryo destruction, or one opposes embryonic stem cell research and accepts that the potential benefits of this research will be foregone. Continue reading

How the Danziger Story Advances the Abortion Debate in America: Actual Futures, Moral Status, and Common Ground

It has become commonplace in recent years to note that the ‘abortion debate’ in America has become entrenched. Indeed, there seem to be few issues in contemporary politics that elicit less common ground than the abortion debate finds in its stalwartly pro-choice and pro-life opponents. It is just as common, if not more so, these days to speak of the ‘attack on Roe v. Wade’ or ‘the attack on women’s rights,’ particularly in light of recent findings that more abortion restrictions were enacted between 2011 and 2013 in the U.S. than in the entire previous decade. Now more than ever, especially for the pro-choice movement, it is necessary to conceptualize novel approaches to the questions of the beginning, end, and quality of life that sit at the heart of the abortion debate. Here I examine a recent case and how it has the potential to advance this debate. Continue reading
