This presentation by Professor Tom Regan (North Carolina State University, USA) was recorded at the University of Heidelberg in Germany on May 24, 2006. It is a great resource for the classroom and anybody with an interest in animal ethics.
Abstract. Philosopher Tom Regan begins by contrasting the fact that many people make a firm distinction between the animals they live with (cats and dogs, for example) and other animals. He explains how it is that Animal Rights Advocates (ARAs) extend the same sense of compassion and respect that they feel for companion animals, on the one hand, to the other animals who routinely are turned into food, clothing, and the like, on the other. Not all ARAs, he explains, arrive at this destination in the same way. In particular, some need to be convinced; some need a logical argument. Professor Regan accepts this challenge and invites others to consider the main factual and moral questions whose answers inform the conviction that animals have rights.
