In this seminar, we will take a voyage together exploring the biological and cultural evolution of individual identity, and the consequences of our self-perspective for major global, social, and environmental issues.

Part one draws on evidence from molecular biology and neuroscience, such as how most of our 37 trillion cells have such a short lifespan that we are essentially made anew every few weeks, whilst the bacteria, fungi, and viruses that make up our bodies influence our moods and even manipulate our behavior. This is combined with evidence from neuroscience and psychology to challenge the sense of ourselves as unchanging, discrete entities. For example, every word and every touch we receive from other people transforms the neural networks in our brain. In Part 2, we will encounter how our sense of identity as isolated individuals is an illusion that is becoming increasingly maladaptive in the modern world. It is responsible for many interlinked environmental, health, and economic problems and we will critically explore the proposition that solving these urgent problems lies in transforming our self-identity.
