Virtue Ethics and Democracy Paper

Tomorrow the Queen's Political Philosophy Group will be discussing my new paper titled "Virtue Ethics and the Democratic Life". The group is very good at highlighting the problems with an author's argument- bringing to the fore an author's hidden assumptions, misinterpretations, mistakes, etc. so it should be fun!

A draft version of the paper is available on my academia.edu page,

Cheers,

Getting to Age 100... How Healthy Are Centenarians in the Years Leading Up to that Milestone?


One of the central concerns people often express about longevity science is the worry that science might just extend the number of years we live in a frail, disabled state at the end of life. Our goal should be to "add life to years, rather than simply adding (unhealthy) years to a long life".

The good news is that an aging intervention would most likely address exactly that concern. The bad news is that the current approach of the biomedical sciences (what I call "negative biology"), by striving to tackle each specific disease of aging, is doing *precisely* what we all don't want- extending the amount of time we live managing multi-morbidity, with diminishing quality of life.

So this study appears to be more good news. It looks at how healthy people who make it to age 100 are. Not surprisingly there is variation. But "positive biology" encourages us to focus on the puzzle of explaining the most exemplary of those with exceptional health in late life (e.g. those individuals who escape/or delay the chronic diseases that ravage most people decades earlier). Here are the results of the study:

As they age to 100, centenarians are generally healthier than nonsurviving members of their cohort, and a number of individuals who become centenarians reach 100 with no self-reported diseases or functional impairments. About 23% of centenarians reached age 100 with no major chronic disease and approximately the same number had no disability (18%). Over half (55%) reached 100 without cognitive impairment. Disease and functioning trajectories of centenarians differ by sex, education, and marital status.

Biologically Modified Justice (now forthcoming...)

For the past 15 years I have been working on my book titled Biologically Modified Justice, which is an examination of some of the ethical and social implications of the genetic revolution.

I was thrilled to learn this week that Cambridge University Press has agreed to publish this book. This project has been a true (and lengthy!) labour of love. Now that I am in the final stretch of completing it I thought I would share some reflections on the challenges and joys of writing an interdisciplinary book over so many years.

The book develops a series of ideas, insights and arguments I have published over the past 13 years in diverse journals ranging from Bioethics and the British Medical Journal, to Biogerontology, Social Philosophy and Policy, Hypatia and the Annals of the New York Academy of Sciences. In addition to the external referees who evaluated the complete manuscript for CUP, various chapters of the book started as journal articles and thus were examined by (this is a rough total estimate) some 40-50 referees in philosophy, political science, medicine, geriatrics, genetics, biogerontology and evolutionary biology.

Receiving feedback from such a diverse range of experts proved to both enormously helpful as well as extremely daunting and challenging. By subjecting my work to review by scholars in different disciplines I have forced myself to transcend some of the limiting assumptions and myopic theoretical frameworks that arise from the inward disciplinary specialization typical of any one discipline (especially political philosophy). I did not want to write a book on the genetic revolution that would only appeal to, let alone be comprehended by, political philosophers (many of whom tend not to see the relevance or importance of the genetic revolution, or the biomedical sciences more generally). I wanted to write a book that would stimulate discussion and debate between scholars in many different disciplines so that we increase the probability that we will implement sensible and fair policies concerning the goal of directly modulating our biology via new genetic interventions.

The book brings together ideas I have published in these venues:


Empirical Ethics and the Duty to Extend the Biological Warranty Period
“Normative Theorizing about Genetics”
“Patriarchy and Historical Materialism”
Equality and the Duty to Retard Human Aging” .
Why Aging Research?”
Framing the Inborn Aging Process and Longevity Science” .
Preimplantation Genetic Diagnosis, Reproductive Freedom, and Deliberative Democracy
Towards a More Inclusive Vision of the Medical Sciences
Aging Research, Priorities and Aggregation
Genetic Justice Must Track Genetic Complexity
Has the Time Come to Take on Time Itself?”
Gene Patents and Justice
The Genetic Difference Principle
Genes and Social Justice: A Rawslian Reply to Moore"

A number of specific events proved to be important catalysts in determining the shape of the project. The first formative influence was I had the opportunity to co-teach a graduate level course at Manchester University in 2002 with an excellent colleague. This was a year after the draft sequences of the human genome were published in Nature and Science. It was the first time I taught the course, and we had students from diverse disciplines in the course- politics, philosophy, law and medicine. That experience convinced me there was a number of important issues worth thinking about more seriously, and that interdisciplinary dialogue and debate was absolutely crucial for tackling these issues. The issues were way too complex and challenging to approach with the armchair theorizing so prominent in analytic political philosophy.

A second event was my growing disillusionment with "ideal theory" in discussions of justice. I had completed this book on that topic a decade ago and its concerns informed the methodology I developed for this new book on the genetic revolution. I remember the merging of these two concerns (non-ideal theory and the biomedical sciences) became explicit in my mind after attending a talk by a philosopher on the topic of genetic enhancement. The author argued that genetic enhancements are morally permissible, assuming of course they were safe and equally accessible to all. During the question period I asked the author what their view was if the latter condition did not hold. Did they think genetic enhancements were morally permissible if they were not, at least initially, equally accessible to everyone in the world? I pointed out that such technologies would cost millions of dollars in research, and may or may not ever become a reality. Assuming they did become a reality they would be costly at first and thus not likely to be equally accessible to all. So I was curious if this philosopher still thought genetic enhancements were morally permissible in that scenario.

The response the speaker gave was that they were talking about what is permissible in ideal theory, so concerns about unequal access did not arise. This response let me bewildered and troubled. To me, the question of whether or not genetic enhancements were morally permissible was a live, pressing and interesting question precisely because concerns about safety, efficacy, and accessibility arise. Philosophers would not have to spend time thinking about the moral permissibility of such technologies if they were guaranteed to be safe, effective, cheap and available to all. What is controversial about such interventions? It would be like arguing that a free gym membership for all is morally permissible. The whole point of the intellectual exercise, for me, was to figure out what the proper attitude to take was in the non-ideal "here and now" context. Should we support or oppose the prospect of genetic enhancements? How much risk of harm is reasonable in this context? Should such technologies be privately or publicly funded, and why? But all of these important questions become null and void if one just declares they are a card-carrying member of the "ideal theory" club.

I could not help but feel that the type of response this philosopher made (and it is a very common attitude among political philosophers) was somewhat intellectually dishonest. Who, other than an analytic philosopher specializing in abstract, idealized accounts of distributive justice, would think invoking such fanciful and obviously false empirical assumptions could be a helpful part of the intellectual exercise and discussion? Instead of writing a book on ideal theory, that would be about ideal justice plus an "add genetics and stir" approach, I decided to undertake a much more burdensome but, I think, interesting project. I wanted to learn about the biological sciences, the role genes play in different diseases, the risks and costs associated with gene therapy, the evolutionary explanations of senescence and experiments on the biology of aging. Staying abreast of these scientific findings consumed most of my research for well over a decade. All the while I had no guarantee that a viable book could emerge from this effort. It was a very risky project. But one I felt compelled to undertake and could, professionally, afford to take as I continued to publish in more mainstream venues and topics in philosophy and political theory (so tenure and promotion were not put at risk).

In 2002 I was also fortunate to attend a Wellcome Trust weekend workshop on genetics, which involved getting a tour of the Sanger Institute where part of the human genome was sequenced. Participants in the workshop had the opportunity to extract the DNA from a strawberry and we also participated in group discussions related to the regulatory and ethical issues of genetic technologies. Engaging with scholars from different disciplines on these issues reinforced my conviction that interdisciplinary dialogue and outlook, rather than inward specialization (i.e. idealization and abstraction), was the way for me to move forward with this project.

I was very fortuitous to have the opportunity to spend my first sabbatical at Oxford University for the year 2006/07. I spent time with the theorists in the Centre for the Study of Social Justice and time among the philosophers working on topics in the biomedical sciences. It was a wonderful opportunity to develop new ideas, engage with very bright scholars in the field, and read and write. I also organized this conference on "Genetics and Justice". 7 years later, on my next sabbatical, I spent a term at UCLA where I taught a graduate version of my course on this topic to MA students in public policy. These diverse educative opportunities were crucial in helping to keep me motivated and focused on completing this book project.

Another important influence on this project was learning about, and engaging with, the scientific field of study on aging and longevity. In 2005/6 I was still primarily committed to writing a book on genetics and justice that was "intuition driven". This means the litmus test in terms of determining how defensible my normative prescriptions were were my own intuitions. When I first began to seriously consider life extending technologies I was unsure what my intuitions were. There seemed something inherently unfair about worrying about extending the human lifespan when so many people in the world died before reaching late life. So while I was not opposed to research on such technologies, and a potential aging intervention, I did not think it was a pressing concern. And certainly not a priority in terms of investing scarce public funding. But then I decided to seriously listen to the arguments of the biogerontologists who argued for greater public investment and support of their science. I was very impressed by what I heard and learned. I also began to learn about evolutionary medicine, and about global mortality and morbidity trends and then it all came together. While my initial intuitions did not tell me that slowing human aging was an important or viable aspiration for humanity, the rapid rise of chronic disease, the marginal health dividends of tackling specific diseases and the incredible advances being made with understanding how to modulate the aging process convinced that it was.

The final, and perhaps most important influence on my project was my laboratory-- the classroom. For more than a decade I taught undergraduate and graduate students a seminar on "Science and Justice" (which focuses on the genetic revolution). Over that time I estimate that approximately 150 students took my seminar at the University of Manchester, Waterloo University, Queen's University and UCLA. In these seminars I asked students what they thought about the issues, I presented different sides of the arguments, I presented my own positions and listened to, and engaged with, their objections. Year after year I became more convinced that political science students longed to engage in normative questions concerning the regulation of the biomedical sciences. And each year I found that existing normative frameworks were often ill-equipped to do justice to the complexity and nuances of the issues typically at stake in this domain. My students believed that science was vitally important to their future and they wanted to think cogently, imaginatively and rationally about the role science could play in helping to create a more humane and fair future. My teaching this class was an intricate part of my research for this book.

The “biologically modified” account of justice I develop is a theory of distributive justice that possesses three distinct characteristics:

(A) it brings insights from biology to the foreground of a normative analysis of the demands of justice. The fundamental orienting assumption of biologically modified justice’s is Dozhansky’s claim that “nothing in biology makes sense except in the light of evolution”.

(B) it focuses primarily, though not exclusively, on the novel benefits and burdens which may arise out of the genetic revolution.

(C) a biologically modified theory of justice adopts a particular kind of methodology. Rather than advancing a normative analysis that privileges idealized assumptions or abstract theoretical experiments, biologically modified justice emphasizes the importance of adopting a pluralistic, “contextual” analysis of the issues and topics it addresses. Biologically modified justice advances an account of justice that is much more interdisciplinary than the kinds of theories of justice typically advanced in political theory/philosophy. The account of the duty to aid advanced in Part 1, for example, is predicated upon insights from demography and biogertonology. The account of “genetic justice” developed in Part 2 modifies the demands of Rawlsian justice by taking seriously insights from epidemiology and genetics. The framing of the benefits of life extension draws on insights from prospect theory. The analysis of the scope and limits of reproductive freedom advanced in Part 3 relies upon the commitments of “deliberative democracy”. And finally the analysis of the creation and evolution of patriarchy invokes the account of historical materialism advanced by Karl Marx as well as insights from evolutionary biology.

Rather than relying on one theoretical tradition or championing one or two particular normative principles, biologically modified justice advances a pluralistic, contextual analysis. As such, many of the conclusions I reach are very provisional, as they are open to revision in light of new empirical discoveries and moral insights. Below are the provisional conclusions I argue for in the book:

(1) There is a pressing moral imperative to extend the human “biology warranty period” by slowing the rate of molecular and cellular decline. The goal of extending lifespan by retarding the rate of biological aging is distinct from the goal of preventing avoidable mortality by tackling each specific disease of aging (e.g. cancer, heart disease, and stroke).

(2) Inequalities in our biological capacities (e.g. ability to repair DNA damage, regulation of cell division, antioxidant defence, immunity, etc.) to realise the natural primary goods are to be arranged so that they are to the greatest reasonable benefit of the least advantaged (what I call the “lax biological difference principle”).

(3) there is a conditional moral presumption in favour of gene patents that satisfy a stringent utility requirement.

(4) There is a strong presumption in favour of procreative liberty and thus parents should have the freedom to utilize PGD for both medical and non-medical purposes. This liberty is subject only to such reasonable limits prescribed by law as can be demonstrably justified in a fee and democratic society.

(5) The degree and form of patriarchy present in any particular society is determined by the productive forces it has had at its disposal. Technological, material and medical advances that ease the pressures on high fertility rates (such as the sanitation revolution, vaccinations, birth control, etc.) are the real driving force behind the positive modulations to patriarchy witnessed in the twentieth century.

I wrote this self-reflective blog post on finishing this book primarily for my own benefit (it's a kind of therapy for me! :)), and for the possible benefit of junior scholars who might be slugging away on writing a book and perhaps struggle with finding the motivation to complete it. Why write, and publish, a book? The absolute worst answer to this question is-- "because I need to to get tenure and/or promotion!". It may be true you need to write a book to achieve those things, but why write *this* book, the book you think or hope you are writing? You must go beyond purely careerist instrumental reasoning to stay motivated and engaged in creative, worthwhile scholarly research. Engage in self-reflection frequently, so the following questions are alive in your mind at all times- "what is the significance of this project?", "Why should I be the person to write this book?", "Who am I writing for?" etc. These types of questions should be consistently returned to over and over again. At least doing so has helped me keep my motivation and attention focused on the end-game of completing this book. Perhaps others respond to different incentives.

The book is approximately 115,000 words in length. And here is the table of contents:

Preface
Introduction
Chapter 1: The Genetic Revolution

Part One: The Duty to Aid in an Aging World

Chapter 2: Empirical Ethics and Singer’s Principle of Preventing Bad Occurrences
Chapter 3: The Duty to Extend the Biological Warranty Period
Chapter 4: Equality and the Duty to Retard Human Aging
Chapter 5: Framing the Inborn Aging Process and Longevity Science

Part Two: Genetic Justice

Chapter 6: Science and Justice
Chapter 7: Genetic Justice and the Limitations of Formulating Distributive “Ideals”
Chapter 8: Normative Theorizing about Genetics: A Response to Loi

Part Three: Patents, Reproductive Freedom and Patriarchy

Chapter 9: Gene Patents and Justice
Chapter 10: PGD and Reproductive Freedom
Chapter 11: Historical Materialism and Patriarchy

Conclusion


Once I get the final edits of this book completed (which still constitute a lot of work) I already have a contract for a textbook on genetics and ethics with Polity Press that needs to be completed, and then I hope to undertake some substantive new research on the topics of play, virtue epistemology, non-ideal theory and punishment.

"Back in My Day!" [er, well, when I was a kid anyways! :) ]



This morning I happened to be reading an article from a 1970s issue of Ethics when I was struck by the difference in length and reliance on citation/notes typical of articles in the journal from 40 years ago. So I decided to compare the Jan 2015, 2005, 1995, 1985 and 1975 issues of the journal to get a sense of how philosophical articles in the journal have transformed over that time. Here is what it looks like [I'm assuming one page length then = one page now]:

1975: average size of article is 13 pages with 17 references/notes.
1985: 14 pages and 25 notes
1995: 22 pages and 47 notes
2005: 33 pages and 53 notes
2015: 23 pages with 57 references/notes.

Many of the “notes/references” section of an article published today probably approximate the article length of some articles published 40 years ago.

Assuming (as I think is reasonable) this data indicates a larger trend in journal article publishing in philosophy, I think it is worthwhile pondering how prudent our current expectations are. Does the typical paper published today better exemplify the “intellectual virtues” we want the discipline to exemplify?

When one goes back and reads a great paper in the journal from say the 1970s it is amazing how “trim” and focused the argument and analysis can be, given the shorter length and minimalist reliance on extended notes, the need to attend to all the minor moves and distinctions, the need to demonstrate familiarity with the extended literature in the field, etc.

The specialization of the discipline over the past four decades has really altered the *skill-set* of the enterprise. Here is an interesting test—search through the archives of the journal and pick out a random article from the 1970s and read it. Then pick out a random article from the past decade and read it. Which do you enjoy reading more? Which article did you learn the most from? I ask these questions because I think it is important to critically reflect upon the current practices we employ in the profession. Perhaps the most basic practice is how we write journal articles. Things have significantly changed over the past few decades (e.g. many more journals, especially in ethics and political philosophy) but I’m uncertain as to how beneficial those changes have been in terms of refining the “intellectual virtues” one believes the profession should seek to cultivate.

I think there is something troubling about the way the discipline has transformed over the past 40 years. Consider, for example, two exemplar papers from the 1970s: Singer’s “Famine, Affluence and Morality” PPA 1972 and Judith Jarvis Thomson “A Defence of Abortion” PPA 1971. The former is 14 pages in length and has just 5, yes 5!, references/notes. And Thomson’s paper is 19 pages and 8 references/notes. You just can’t write (or at least publish in a top journal) articles like that anymore. Sure there are admirable lengthy papers, but I think something valuable has been lost in terms of how we conceive what the philosophical enterprise ought to be. And that concern is not simply stylistic (e.g. papers should be shorter). The stylistic issues concern me because I believe they have an impact on *substance*. They impact the way we conceive of what is manageable and desirable to write about and engage with in an article.

Colin

New Paper on Virtue Epistemology and Democracy (Work in Progress #1)

I am currently writing a commissioned article (for OUP's Oxford Handbook on Virtue) on virtue epistemology and democracy. In this first blog post I want to briefly outline the basic framing of the exercise, at least as I have it worked out so far.

Very General Frame: virtue ethics has a PR problem when it comes to democracy. It is typically associated with anti-democratic ideals, and its main historical proponents (namely Plato and Aristotle) criticized democracy. This article aspires to show how the virtue ethicist’s focus on what kind of person we should be can yield valuable insights for democratic theory.

More Specific Frame: Integrating insights from the Ancient Greeks (e.g. concerning virtue, eudaimonia and democracy), John Dewey and recent work in virtue epistemology, I argue that an account of democracy which conceives of democracy as an “inquiry-based mode of social existence” can overcome three common objections typically raised against democracy. These three objections are:

The Irrationality Objection (Downs)- why bother voting, or even learning about politics, considering your one vote will incur a certain cost on you for no (likely) benefit?

The Autonomy Objection (Wolff): democracy violates moral autonomy. The latter requires us to take responsibility for making the final decisions about what to do. Both representative democracy and majoritarian democracy violate our moral autonomy.

The Objection from Epistocracy (Plato/Mill): democracy is rule by the ignorant. A better political system would ensure those with expertise (for Plato this is philosophers) govern or, in the case of JS Mill, have more votes.

What all three of these objections to democracy share is they tend to equate democracy with a political system of majority rule voting. But this is a very narrow, and superficial, understanding of democracy. The original Greek meaning of democracy is- "the collective capacity of a public to make good things happen in the public realm". This understanding of democracy lends itself well to a virtue epistemological analysis of democracy, for virtue epistemologists define knowledge as ‘success from ability’ (Greco, 2010, p. 3) or ‘a state of cognitive contact with reality arising out of acts of intellectual virtue’ (Zagzebski, 1996, p. 270).

In the bulk of the paper I then proceed to formulate a virtue ethics defence of democracy (understood not as a form of government, but as "a life of free and enriching communion” (Dewey)). This defence emphasizes the importance of the "intellectual virtues" cultivated and refined by the democratic way of life. If successful, this account of democracy yields an account that explains how living a democratic life is rational, autonomous and conducive to creating knowledge. This is still very provisional and subject to revision as I still have a few months of work left on the paper and will no doubt be tweaking the main conclusions further.

Comments on the blog are closed, but I will post this on FB as well and friends are welcome to make FB comments pertaining to suggested readings, obvious mistakes I'm making!, demolishing objections I must address, etc.

Cheers,
Colin

Framing One's Worldview

I posted this on my FB and any academics currently not FB friends that wish to send along their answers can email me. thanks

Non-scientific poll for philosophers and theorists who teach on topics like global justice, equality, democracy, freedom, etc.

Question #1.

When you reflect upon the way you frame with subject matter you teach, is there an apparent "Negative Worldview" (humanity is heading towards the dumps) or "Positive Worldview" (humanity's prospects are improving and will likely continue to do so) perspective that you have?

Question #2.

If you answered "yes" to number 1, please briefly expand upon the factual accuracy of that perspective. What I'm specifically interested to hear about are (a) the timeframe of comparison you typically invoke (e.g. How things were compared to 20 years ago, or 200 years ago, or 20 000 years ago or compared to some counterfactual or hypothetical state-of-affairs, etc.) and (b) the variables or measure you use to draw such conclusions (e.g, is it life expectancy, level of socio-economic inequality, number and health of democratic countries in the world, etc.).

Cheers,
Colin

The Problem

Humanity faces a major problem (what I refer to here simply as the Problem) this century. And given the nature of the Problem it will most likely be a significant problem for all future generations as well, unless we seriously tackle this problem.

The Problem is one of the most significant problems we have ever faced. Sadly not very many people realize how big of a problem the Problem is, and few believe there is anything we can do to remedy the Problem. Thus people do not pressure their governments to take action to address the Problem.

There is an extremely strong scientific consensus concerning the likelihood that the Problem will impose unprecedented levels of suffering, disease and disability on people in both rich and poor countries. Indeed this is a certainty if we do nothing to prevent the Problem. Furthermore, the Problem threatens to undermine the economic prosperity of all nations, rich and poor alike.

Humanity is collectively responsible for the Problem. Our actions, especially over the past century and half, have made the Problem the reality it is today. If we hadn't pursued the actions we did, the Problem would not exist. It's a "man-made problem", and the only way to fix it is with a "man-made solution".

Some claim we should just focus on "adaptation" to minimize the harms of the Problem. Those taking this position doubt we can do anything to directly alter the certainty and severity of the problem. And yet many of the scientists with expertise on the nature of the Problem believe we can directly manipulate the factors responsible for the Problem. Numerous scientific experiments have demonstrated that the biological processes involved in senescence (aging) can be modulated, thus slowing down the rate of molecular and cellular decline. So if you hadn't yet guessed it, the Problem is GLOBAL AGING (what did you think it was?)

By the middle of this century there will be 2 billion people in the world over the age of 60. Most people over the age of 60 suffer from at least one serious medical condition, if not more. And they are a significant risk of co-morbidity. The number of people who die from age-related chronic disease each year is unprecedented. Never before in human history have so many humans died from such a slow and painful (and expensive) death.

Global aging is a product of human action. Civilization has become so successful at preventing early and mid-life mortality- thanks to public health measures like the sanitation revolution, immunizations, antibiotics, changes in behaviour and increases in material prosperity- that our populations now age. This was not the case for 99.9% of our species' existence. Life expectancy at birth for humans was 30 years or less for the vast majority of the time homo sapiens existed. Today it is age 70 for the world as a whole, and is expected to rise to age 80 by the end of the century.

While in many respects this is an incredible success story, it is also a story of the creation of a new and novel health challenge- the challenge of keeping our bodies and minds healthy beyond the biological warranty period (estimated to be approximately 70 years) that evolved from our life in hunter gather societies.

Given the rapid rise of chronic disease that has already occurred, and will dramatically rise this century as populations age, what can be done? The strategy of adaptation is one that simply takes the biology of aging we have inherited from our specie’s life and evolutionary history as a given, and looks for ways to minimize the harmful effects of aging. So promoting exercise, or tackling specific diseases of aging by funding medical research on cancer or Alzheimer’s disease, or redesigning cities to better promote the mobility of aging populations, raising the age of eligibility for social security, etc. these are all adaptive solutions. They are important, but of very limited impact. Eliminating all 200+ types of cancer would only likely increase life expectancy at birth by a few years (e.g. 3 years) because those most at risk of death by cancer (age >60) would simply die from one of the other major causes of age-related death, like a stroke or heart disease.

A more ambitious and rational strategy would be to aspire to modulate aging itself. Some humans naturally possess the ability to retard the normal rate of aging. Centenarians and supercentenarians (age > 110) possess “longevity genes” that delay and even insulate them from the more common health conditions that afflict the normal person decades earlier. I believe the development of a drug that activates the “anti-aging” genes these rare individuals naturally possess would be, by far, the most significant advancement in medicine this century. It would, at a minimum, simultaneously delay age-related frailty, disease and disability. It might also compress morbidity and mortality at the end of the lifespan, so that the period of time it takes to die once our health has faded is shorter than how we die under the normal rate of biological aging. Retarding human aging could dramatically increase the health span and reduce the period of time humans will suffer chronic disease. Such an intervention could be something all future generations benefit from as well. There are hardly any global problems as pressing and significant as tackling aging is today.

Cheers,
Colin
