We have a number of invited speakers from within mathematics and in other disciplines who will talk about diverse topics. We have two distinct classes of speaker.

The first is a collection of these mathematicians who have worked on ethics in mathematics. These are people who have either written articles or papers on the relevance of ethics in mathematics, or who have delivered their own course on ethics in mathematics to mathematicians.

The second class is a collection of allied experts from outside mathematics with relevant experience and knowledge. These include: a psychologist with experience with Autism and Aspergers, a lawyer with experience in mathematical technology, a philosopher who specialises in ethics, and a mathematician-turned-whistleblower with 30 years experience working for the NSA.

This is a vital interdisciplinary aspect of the workshop; it takes several people from several areas to make this effective.

The workshop will be opened by a pre-recorded message from Sir Michael Atiyah (Fields medallist and former president of the Royal Society) who, as well as being one of the most prolific British mathematicians of the 20th/21st century, has also been heavily involved with, and spoken openly about, ethical issues that relate to mathematics. There will be ample time allocated for group discussion, both structured and unstructured.

This workshop is the initiative of Dr Maurice Chiodo, with the close assistance of Dr Piers Bursill-Hall. Since April 2016, they have been spearheading an effort from within the Faculty of Mathematics in Cambridge to teach ethics to mathematicians. This has led to the formation of the Cambridge University Ethics in Mathematics Society, a series of student seminars titled Ethics for the Working Mathematician delivered by Dr Chiodo, shortlisting for an award by the European Commission on Contribution to a better society with a concurrent invite to participate in a panel discussion during the ceremony, a workshop co-organsied with Martin Hellman on Ethics in Mathematics and Computer Sciece at the Heidelberg Laureate Forum 2017, a research grant from the Teaching and Learning Innovation Fund of the University of Cambridge, an invitation by the London Mathematical Society to participate in the Voice of the Future event in the Houses of Parliament, and finally this workshop.

Maurice Chiodo
Postdoctoral researcher in mathematics

Maurice Chiodo is a postdoctoral research fellow in the Department of Pure Mathematics and Mathematical Statistics at the University of Cambridge, bye-fellow in mathematics at King's College Cambridge, co-ordinator at the Cambridge University Ethics in Mathematics Society and lead investigator of the Cambridge University Ethics in Mathematics Project.

Piers Bursill-Hall
Lecturer of History of Mathematics

Piers Bursill-Hall has spent most of his academic life in the Department of Pure Mathematics at Cambridge (with occasional forays out of Cambridge for good behaviour). He has taught undergraduate courses in history of mathematics and most aspects of history of science. His research and teaching has concentrated on history of Ancient, Renaissance, and Enlightenment mathematics and mathematical arts, and more recently a small detour into early Islamic mathematics and science.


University of Cambridge, Centre for Mathematical Sciences,
Wilberforce Rd, Cambridge, CB3 0WA.
The workshop will commence at 09:00 on Friday 20 April, and conclude at 18:00 on Saturday 21 April.
All talks will be held in room MR4
(Enter through the main entrance and go down the stairs; there will be signs).

That the practice of mathematics can invoke ethical issues is probably obvious to everyone – but not to most mathematicians. It is also obvious that high-powered and sophisticated mathematics is ubiquitous in modern technology, finance, the nation’s infrastructure and defence, and social media. And pretty much anywhere else in the 21st century. Much of mathematics can be used for good – but simply put: it can also be a tool for harm. We think it is clear that mathematical research and practice may take its practitioners to deep and professionally specific ethical issues.

So far as we know, there is no university in the world that currently offers a wide-ranging specifically mathematical ethical training for mathematicians. For lawyers, medics, biologists, computer scientists, physicist, and others, the question of subject specific ethics is not news – it is part of their training, part of their professional practice and regulation, and part of their understanding of their work as professionals. It is striking that this is not the case for mathematicians.

There have been a number of studies and smaller or larger projects that have looked at specific ethical questions in mathematics; it is well known that statistical practice and the public dissemination of statistics is dense with ethical questions, and the use of algorithms in all sorts of decision making systems has, in the last few years, elicited some public and professional investigation. The role of mathematicians developing financial instruments that were little understood by the rest of the financial industry has come to light because of the financial crisis of the 2000s. Moreover, the use of extremely sophisticated mathematical tools by the state security institutions around the world has raised deep questions about cyber- security and privacy – and it is mathematicians who are developing the tools that enable these bodies to place the entire population under extraordinary and detailed surveillance. But such studies have been limited, and focussed on the very particular technical details in each of these domains. Many of these studies have been both fascinating and deeply worrying. However, all of this has focussed on narrow issues – and they have succeeded exactly because of this focus. It is now time for a broader discussion to start, a discussion about all mathematicians in society, about the professional social responsibility and the ethics of which mathematicians are often quite extraordinarily ignorant. Whereas such training is normal in other disciplines, for mathematicians it simply doesn't exist, anywhere. Until now. In Cambridge we have recently set up and run an annual seminar series titled Ethics for the working mathematician, where we developed entirely new content including case studies, and analysis of ways that ethics enters into mathematics. A reasonably large minority of undergraduates have attended these seminars, and they are – to some extent – working: there are now some undergraduate mathematicians who have taken on board the idea that regardless of what mathematical work mathematicians end up doing as a professional, they will most likely come up against ethical issues.

This meeting is – we think – the first such meeting aimed at bringing together some of the people (that we in Cambridge happen to know of) who have worked on issues of ethics in mathematics, who have tried to start a teaching course on ethics for mathematicians in their universities, or who have published something about ethics in mathematics. The recurring problem we have observed is that almost all such people are "singletons" working alone, sometimes with mere disinterest from their institutions, sometimes meeting active hostility from colleagues. We want to bring these people together to make a community - and the tiny kernel of a new discipline: the study of Ethics in Mathematics. Not just the ethics of algorithms, or mathematicians working for the intelligence services, but all mathematics and all mathematicians. We want to broaden the discussion to grasp the role of mathematics that has grown in the last 20-30 years, where almost everything we have or we do has a vast amount of highly technical, highly specialised mathematics behind it, and which is utterly incomprehensible to almost everyone who is not a trained mathematical professional. Mathematicians have become one of the most powerful communities in the world, yet they do not know it, and do not know how to take responsibility for their actions; nobody ever tells them.

Nobody can do this from outside the profession. Only mathematicians can talk to mathematicians about ethics: the discourse of philosophers (which is infinitely more sophisticated than anything we can hope to achieve) will go over the heads of most mathematicians, and simply will not address the specifically mathematical, technical ethics we face. The ethical questions of computer scientists or economists, physicists or geneticists, are pressing and important – but they are not those of the professional mathematician and they are not going to teach her how to deal with the issues that she may face in the working environment of mathematicians. So only mathematicians can do this, and we need to begin the process of forming a community: supporting each other, sharing knowledge, experiences, best practice, and a vision of what we can teach our students.

The workshop we are organising is a small first step in doing something really innovative and creating a new (and deeply multidisciplinary) project. It will be the first such meeting, and it will necessarily be a small pilot project, bringing together a small group of mathematicians we know to be interested in ethics in mathematics and who have tried, one way or another, to research or teach this. We will bring together some experts in fields outside mathematics to talk to the mathematicians about the particular properties of the nature of the mathematical community and mathematicians, and the reasons for the failure of mathematicians to contribute to policy and ethical considerations outside their own very narrow domains. This group of mathematicians already knows about the issues of ethics in mathematics, but they have no working community and little experience with those outside mathematics who may be able to inform or deepen their own thinking about the ethics of mathematical research and practice.
