On 21 August 2014, Maria Kasmirli and I gave a joint paper at the ‘Knowing Minds’ conference in Sheffield, held to mark the retirement of George Botterill from the University of Sheffield after 26 years. It was a pleasure to take part, to see so many old friends again, and most of all to express our gratitude to George, under whom we had both studied during our time at Sheffield. Our paper, which was titled ‘Shall we go upstairs? The ethics of implicated consent’, discussed issues surrounding the giving of consent by indirect means. Here are the slides from our talk.
