Are human beings like any other animals? This is the question Georges Chapouthier answers by showing the thin limits between animality and humanity. Chapouthier starts his lecture by summarizing the human point of view on animals throughout history, and then recalls the similarities between human beings and animals, culture-wise and intelligence-wise. To prove his point, he gives numerous examples of elephants, monkeys, dolphins and birds that demonstrate their culture and intelligence. Chapouthier ends his presentation by listing the characteristics that make human beings different from animals among which are the concept of duration, the use of imagination, and the importance of neoteny.
