Assessing the Moral Status of Robots: A Shorter Defence of Ethical Behaviourism

[This is the text of a lecture that I delivered at Tilburg University on the 24th of September 2019. It was delivered as part of the 25th Anniversary celebrations for TILT (Tilburg Institute for Law, Technology and Society). My friend and colleague Sven Nyholm was the discussant for the evening. The lecture is based on my longer academic article ‘Welcoming Robots into the Moral Circle: A Defence of Ethical Behaviourism’ but was written from scratch and presents some key arguments in a snappier and clearer form. I also include a follow up section responding to criticisms from the audience on the evening of the lecture. My thanks to all those involved in organizing the event (Aviva de Groot, Merel Noorman and Silvia de Conca in particular).

Introduction My lecture this evening will be about the conditions under which we should welcome robots into our moral communities. Whenever I talk about this, I am struck by how much my academic career has come to depend upon my misspent youth for its inspiration. Like many others, I was obsessed with science fiction as a child, and in particular with the representation of robots in science fiction. I had two favourite, fictional, robots. The first was R2D2 from the original Star Wars trilogy. The second was Commander Data from Star Trek: the Next Generation. I liked R2D2 because of his* personality - courageous, playful, disdainful of authority - and I liked Data because the writers of Star Trek used him as a vehicle for exploring some important philosophical questions about emotion, humour, and what it means to be human. In fact, I have to confess that Data has had an outsized influence on my philosophical imagination and has featured in several of my academic papers. Part of the reason for this was practical. When I grew up in Ireland we didn’t have many options to choose from when it came to TV. We had to make do with what was available and, as luck would have it, Star Trek: TNG was on every day when I came home from school. As a result, I must have watched each episode of its 7-season run multiple times. One episode in particular has always stayed with me. It was called ‘Measure of a Man’. In it, a scientist from the Federation visits the Enterprise because he wants to take Data back to his lab to study him. Data, you see, is a sophisticated human-like android, created by a lone scientific genius, under somewhat dubious conditions. The Federation scientist wants to take Data apart and see how he works with a view to building others like him. Data, unsurprisingly, objects. He argues that he is not just a machine or piece of property that can be traded and disassembled to suit the whims of human beings. He has his own, independent moral standing. He deserves to be treated with dignity. But how does Data prove his case? A trial ensues and evidence is given on both sides. The prosecution argue that Data is clearly just a piece of property. He was created not born. He doesn’t think or see the world like a normal human being (or, indeed, other alien species). He even has an ‘off switch’. Data counters by giving evidence of the rich relationships he has formed with his fellow crew members and eliciting testimony from others regarding his behaviour and the interactions they have with him. Ultimately, he wins the case. The court accepts that he has moral standing. Now, we can certainly lament the impact that science fiction has on the philosophical debate about robots. As David Gunkel observes in his 2018 book Robot Rights: “[S]cience fiction already — and well in advance of actual engineering practice — has established expectations for what a robot is or can be. Even before engineers have sought to develop working prototypes, writers, artists, and filmmakers have imagined what robots do or can do, what configurations they might take, and what problems they could produce for hu
